 "all-ceramic lithium alloy anodes.with oxide-based solid (safer, lighter, cheaper, longer performance, faster charging, stable) electrolyte... replacing existing coin-shaped batteries for small electronics (watches)... ceramics are not suitable for larger-sized batteries (even sized for smartphones) where they would be more fragile... start shipping samples of its new battery prototype to clients from next year and hopes to be able to move into mass production after that"
