Researchers in Europe are working on a self-healing 'sandwich' EV battery that aims to address range anxiety.The battery uses a special 'super glue' made of binders and separators to maintain its structure even after damage.The battery features a cobalt-free cathode with less nickel and less lithium, improving charging times and performance.The anode is made from a silicon-graphite composite, providing strength, stability, and larger energy storage.
