ST’s EnFilm™ thin-film batteries are a new concept of extremely thin (220 µm), rechargeable solid-state batteries with fast constant-voltage recharge and a lifetime of more than 10 years or 4000 cycles.
They feature a LiCoO2 cathode, LiPON ceramic electrolyte and a lithium anode, on a 25.7 x 25.7 mm footprint so are completely safe from risks of burning or explosion.
