Battery technology is increasingly evolving and playing an important role in meeting the energy demands of the future. This article details the latest developments in next-generation battery technology and their implications for the year 2025.
Latest Trends in Next Generation Battery Technology
Evolution of Lithium-Ion Batteries
Lithium-ion batteries are rapidly evolving to achieve higher energy density and longer life. Through the latest research and development, high-performance batteries with energy densities exceeding 1,200 Wh/L are being realized. This is approximately 1.7 times the energy density of conventional lithium-ion batteries and has the potential to significantly extend the cruising range of electric vehicles.
Furthermore, the development of new electrode materials utilizing nanotechnology is expected to shorten charging times and extend the life of batteries. For example, anode materials using silicon nanowires have been reported to have more than 10 times the capacity of conventional graphite anodes. If this technology is put to practical use, it could more than double the current battery life of smartphones.
In addition, research into graphene-based electrode materials is underway, which has the potential to significantly reduce charging times. Using graphene-based electrodes, a research team at the University of Manchester has succeeded in increasing the charging speed by a factor of five or more compared to conventional batteries. If this technology is commercialized, electric vehicles could be recharged in one-twentieth the time it takes today, making them as convenient as gasoline-powered vehicles.
The Rise of Solid State Batteries
Solid-state batteries are gaining attention as a next-generation technology that combines safety and energy density: BMW's innovative solid-state battery is said to have an energy density of 1,200 Wh/L and can travel more than 100 km on a 10-minute charge. By replacing the conventional liquid electrolyte with a solid electrolyte, the technology significantly reduces the risk of ignition while simultaneously increasing energy density.The joint venture between QuantumScape and Volkswagen aims to mass produce solid-state batteries by 2025, and the electric vehicle could revolutionize the industry.
In addition, Toyota Motor Corporation is also developing its own solid-state battery technology and aims to commercialize it by 2025. Toyota's technology has been reported to reduce charging time to just 10 minutes and has the potential to travel more than 1,000 km on a single charge. If this technology becomes a reality, the biggest issues facing electric vehicles, namely cruising range and charging time, could be solved in one fell swoop.
Solid-state batteries have the potential to revolutionize not only electric vehicles, but also wearable devices and medical devices. For example, flexible solid-state batteries are being developed for use in bendable electronic devices and medical devices that can be implanted in the body.
Next-generation battery applications
Impact on electric vehicles
Next-generation battery technology has the potential to dramatically improve the performance of electric vehicles.
Goldman Sachs forecasts that the cost of EV batteries will drop by 401 TP3T to $99 per kWh by 2025. This is expected to bring the price of EVs on par with internal combustion engine vehicles and expand their market share to 171 TP3T in 2025 and 351 TP3T in 2030.
If this prediction becomes a reality, the electric vehicle market will expand rapidly and revolutionize the entire automotive industry. For example, Tesla CEO Elon Musk has set a goal of producing 20 million electric vehicles per year by 2030. This is equivalent to approximately 20% of current global vehicle production.
In addition, next-generation battery technology will revolutionize the performance aspects of electric vehicles. For example, the Lucid Air electric vehicle being developed by Lucid Motors has a range of 832 km on a single charge. This is a longer range than many gasoline-powered vehicles and greatly improves the utility of electric vehicles.
The advent of high-performance batteries is also expected to accelerate the spread of commercial vehicles such as electric trucks and electric buses. For example, Tesla's electric truck "Semi" can travel approximately 800 km on a single charge, which may significantly reduce operating costs compared to conventional diesel trucks.
With these innovations, electric vehicles are evolving from just an environmentally friendly option to a superior choice in terms of performance and economy, and it may not be long before electric vehicles become a mainstream part of the automotive market after 2025.
Integration with renewable energy
Next-generation batteries complement the unstable supply of renewable energy and improve the stability of the power grid.
For example, Tesla's Megapack, with a capacity of up to 3 MWh, can store surplus electricity from wind and solar power generation and supply it during peak demand periods. This can significantly increase the use of renewable energy and reduce dependence on fossil fuels.
In addition, next-generation battery technologies are revolutionizing grid-scale energy storage systems. For example, the iron-air battery being developed by Form Energy could enable energy storage for longer than 100 hours and offer a new option for absorbing the variability of renewable energy. If commercialized, this technology could overcome the challenges of solar and wind power variability and accelerate the large-scale deployment of renewable energy.
Advances in battery technology have also contributed to the realization of microgrids. Microgrids are small-scale power grids that manage the production and consumption of electricity on a regional basis, and have the advantage of being able to continue supplying power independently in the event of a disaster. Microgrids utilizing next-generation batteries are expected to promote local production for local consumption of energy and increase the resilience of power systems.
Home Energy Storage
Home energy storage systems are also evolving with next-generation battery technology. LG Chem's RESS, for example, has a capacity of up to 16 kWh and, when combined with a solar power generation system, enables households to become energy self-sufficient. This not only reduces electricity costs, but also serves as a backup power source in the event of power outages, thereby contributing to resilience.
In addition, residential battery systems are beginning to work with power companies to form "virtual power plants" (VPPs). For example, a VPP project using Tesla's Powerwall is contributing to the stabilization of the power grid by balancing the supply and demand of electricity through the integrated control of thousands of batteries. If this technology becomes widespread, it could lead to a new energy system in which each household contributes to the stabilization of the power grid while at the same time benefiting economically.
In addition, advances in next-generation battery technology are leading to smaller and more powerful home energy storage systems. For example, systems using all-solid-state batteries under development by Sony are said to have more than twice the energy density per volume of conventional lithium-ion batteries. This could make it easier to install high-capacity battery systems in urban homes with limited space.
Research and development of next-generation batteries
Major Corporate Initiatives
Major companies around the world are investing heavily in research and development of next-generation battery technologies.
For example, Toyota has announced plans to invest approximately 1.5 trillion yen in battery development by 2030. Tesla is also developing its own 4680 battery cell to improve energy density and production efficiency. In addition, startups are also gaining attention for their innovative technological developments. For example, Israel's StoreDot has successfully developed an ultra-fast-charging battery that can be recharged in five minutes and is aiming for commercialization by 2024. In addition, Sila in the U.S. has developed a silicon-based anode material that has successfully increased energy density by 20-40% compared to conventional lithium-ion batteries.
Competition and cooperation among these companies is driving rapid advances in battery technology. For example, BMW and Ford have jointly invested in Solid Power, a developer of solid-state batteries, to accelerate technology development. Such cross-industry efforts could hasten the commercialization of next-generation battery technology.
Government support and regulation
Many countries are supporting the development of next-generation battery technology.
For example, the EU has announced plans to invest approximately 300 billion yen in battery R&D by 2025. In addition, governments have introduced subsidy programs and regulations to promote the spread of electric vehicles, and these policies are encouraging the development of next-generation battery technology.
Of particular note is the Chinese government's aggressive support measures. China has formulated a "New Energy Vehicle Industry Development Plan" with the goal of increasing the share of new energy vehicles in new vehicle sales to at least 20% by 2025. This policy has led to the rapid growth of Chinese battery manufacturers such as CATL and BYD, which are expanding their share of the global market.
At the same time, regulations regarding the procurement of battery materials, the environmental impact of the production process, and labor issues are being tightened. For example, the EU plans to introduce regulations requiring disclosure of the carbon footprint of batteries by 2024. These regulations are expected to have the effect of encouraging the development of more sustainable battery technologies.
Challenges and Prospects for Next-Generation Batteries
Cost Reduction
Reducing costs is essential to the widespread adoption of next-generation battery technology.
Currently, the battery pack of an electric vehicle accounts for about 301 TP3T of the total vehicle cost, which is the main reason for the high price of electric vehicles.
However, technological innovation and mass production are driving battery costs down rapidly: BloombergNEF reports that the cost of lithium-ion batteries fell $89% between 2010 and 2020, to $137/kWh. Furthermore, it is projected to break through the $100/kWh barrier by 2024 and drop to $58/kWh by 2030.
Once this price point is reached, the cost of producing electric vehicles will fall below that of internal combustion engine vehicles, and market share could increase rapidly. Key factors for cost reductions include
- economy of scale: Increased production volume helps to spread out fixed costs.
- Advances in Materials Technology: Development of less expensive and higher performance materials is underway.
- Manufacturing Process Improvements: Automation and efficiency can reduce production costs.
- Development of recycling technology: Increased recovery of materials from used batteries will reduce raw material costs.
For example, Tesla aims to reduce production costs by 56% and increase energy density by a factor of five through the development of its proprietary 4680 battery cell. These innovations are enabling a rapid decline in battery costs.
Resource Conservation and Recycling
Securing and recycling the resources needed for battery production is an important issue for the sustainable development of next-generation battery technology. Of particular concern is the stable supply of rare metals such as lithium, cobalt, and nickel. According to a report by the World Economic Forum, by 2030, demand for electric vehicle batteries is expected to increase 19-fold over current demand. To meet this rapid increase in demand, it is essential to develop new resources and establish recycling technologies.
The following are examples of efforts to secure resources
- Development of new mining technologies: For example, a technology for extracting lithium from geothermal power plant wastewater is attracting attention.
- Research on alternative materials: Research is underway to reduce dependence on rare metals, including the development of cobalt-free batteries.
- Development of submarine resources: Extraction of rare metals from manganese nodules existing at the bottom of the deep sea is under consideration.
On the other hand, with regard to recycling, the concept of a "circular economy" is becoming increasingly important, taking recycling into account from the battery design stage. For example, Northvolt aims to manufacture 50% of the batteries it produces by 2030 from recycled materials. In addition, Japan's Sumitomo Metal Mining has developed a technology to recover nickel and cobalt from used lithium-ion batteries with a purity of 99% or higher. The widespread use of such highly efficient recycling technologies is expected to lead to more effective use of resources and a reduction in environmental impact.
Improved safety
Improving battery safety is an extremely important issue for the spread of next-generation technologies. There is a history of fires and other accidents involving electric vehicles that have occurred in the past, which have caused consumer concern. However, the latest technological developments have dramatically improved battery safety.
Key safety improvement initiatives include the following
- Improved thermal management systems: High-performance cooling system ensures proper battery temperature management and reduces the risk of thermal runaway.
- Enhanced separator: Use of heat-resistant separators reduces the risk of internal short circuits.
- Use of sensor technology: A sensor system is installed to detect abnormalities at an early stage and prevent accidents from occurring.
- Advanced software control: An advanced AI-based control system constantly monitors battery status to maintain optimal operation.
For example, the solid-state battery being developed by BMW does not use liquid electrolyte, which significantly reduces the risk of ignition compared to conventional lithium-ion batteries. Tesla has also developed its own "structural battery pack" to improve crash safety. These innovations have dramatically improved the safety of next-generation batteries and are a key factor in gaining consumer confidence.
Summary and Future Outlook
As we move toward 2025, next-generation battery technology is rapidly evolving and could be the key to a sustainable future. New battery technologies with high energy density, long life, and fast recharging are expected to accelerate the spread of electric vehicles and expand the use of renewable energy.
The International Energy Agency (IEA) predicts that by 2030, the global electric vehicle fleet will reach 245 million, about 20 times the number in 2020. This rapid growth will be made possible by advances in battery technology. Next-generation battery technology also has the potential to revolutionize the field of energy storage systems, with BloombergNEF forecasting that by 2030 global energy storage capacity will increase more than 15-fold over current levels, reaching over 1,000 GWh. This will enable the large-scale deployment of renewable energy and contribute significantly to the realization of a decarbonized society.
However, in order to realize these possibilities, there are still challenges to overcome, such as cost reduction, securing resources, and improving safety. Industry-academia-government collaboration and international cooperation are essential to tackle these challenges. It is important to continue to focus on the evolution of battery technology and to take full advantage of its potential.
Next-generation battery technology has the potential to significantly change the way we live our lives and contribute to the realization of a sustainable society. To keep up with this wave of technological innovation, each of us must understand the potential of new technologies and actively utilize them.
