The new batteries exhibit high voltages between 2.45-2.8 V, delivering high capacities close to its theoretical value, which is a first for aqueous-based batteries. Mumbai-born scientist Dr Gautam Yadav has invented a new high-voltage, energy-dense rechargeable manganese dioxide (MnO2) zinc|(Zn) battery, which could be an alternative to Li-ion batteries that have dominated the energy storage […]
