A composite anode made of tin nanoparticles embedded in hard carbon supposedly improves the charging speed and durability of lithium-ion and sodium-ion batteries. Researchers from South Korea have developed this new battery technology.https://www.notebookcheck.net/Next-gen-battery-utilizes-tin-nanoparticles-for-better-charging-and-longevity.1004475.0.html
Unfortunately anything with Nano and baking in batteries costs a lot. But lets home they will partner with someone to actually make these batteries.
