A Japanese research team has created a quasi-solid-state lithium-ion battery (LIB) that is non-flammable, overcoming the drawbacks of traditional batteries.
The innovation, developed by scientists from Doshisha University and TDK Corporation, combines liquid and solid electrolytes to enhance safety and durability. Increasing the energy density of positive and negative electrode active materials typically reduces cycle performance and safety, but the innovation offers a balanced solution.
According to the team, the design offers a safer and more durable solution compared to all-solid-state batteries while maintaining high energy density.
“The improved safety and charge/discharge performance demonstrated the feasibility of quasi-solid-state batteries as a near-future technology,” said the team in the study abstract.
Yesterday, a US battery tech firm, Microvast, claimed that its all-solid-state EV battery breakthrough offers more energy density and a longer range.
