Li metal batteries are promising for energy storage due to their high energy and power density, but they face stability issues with typical Li-ion electrolytes.
Combining Li metal with a polymer electrolyte can enhance safety and performance by addressing key factors like ionic conductivity and mechanical stability.
A new multifunctional polysalt, made from sustainable materials, has been developed to improve compatibility with Li metal and reduce decomposition, allowing for the use of high-voltage nitrile-based plasticizers in polymer batteries.
