New battery needs seconds of sunlight to keep wearables charged

Researchers at Surrey's Advanced Technology Institute have demonstrated a new, highly integrated, flexible photo-rechargeable system based on zinc-ion batteries and perovskite solar cells. It only needs a few seconds of sunlight to keep smart wearables charged.Thirty seconds of sunlight is all it takes for a prototype battery demonstrated by Surrey's Advanced Technology Institute (ATI) to charge with sufficient energy to power other wearables for periods of 10 minutes. The photo-rechargeable system merges stable and ultra-high-rate quasi-solid-state zinc-ion micro-batteries and flexible perovskite ...
