Researchers in Japan have made a breakthrough in lithium-ion battery technology that could address one of the key challenges in electric vehicle (EV) development: creating energy-dense batteries without compromising safety. The new “quasi-solid-state” battery combines solid and liquid components, offering a solution that balances performance with safety.
Led by Ryosuke Kido from Doshisha University and TDK Corporation, the team has demonstrated that their innovative battery design delivers high energy density while significantly improving safety compared to traditional lithium-ion batteries. Their findings, published in the Journal of Energy Storage on November 15, 2024, offer a promising alternative to the risks posed by current battery technologies.
Kido explained that increasing the capacity of battery materials often leads to reduced cycle performance and safety. However, their flame-retardant quasi-solid-state battery, which integrates both liquid and solid electrolytes, offers enhanced durability and safety, making it a viable solution for future EV power systems.
