A spreadable interlayer could make solid state batteries more stable
Solid state batteries are of great interest to the electric vehicle industry. Scientists at Chalmers University of Technology, Sweden, and Xi'an Jiaotong University, China now present a new way of taking this promising concept closer to large-scale application. An interlayer, made of a spreadable, ‘butter-like’ material helps improve the current density tenfold, while also increasing performance and safety. “This interlayer makes the battery cell significantly more stable, and therefore able to withstand much higher current density. What is also important is that it is very easy to apply
