Bhagyashree Avinash kadam presented on bio batteries on 21/01/2024. A bio battery generates electricity from renewable fuels like glucose through enzymes and microorganisms. It allows instant recharging without an external power supply. Bio batteries provide a clean, non-toxic alternative to conventional batteries and do not cause explosions or leakages. When enzymes break down glucose, electrons and protons are released which can be harnessed to generate electrical energy through bio batteries.
