Abstract
A method for rapidly charging an electrically rechargeable battery or batteries string by a series of charging pulses, interspersed with battery discharge pulses effective to eliminate undesired concentration polarization by substantially thinning or dispelling electrical double layers and diffusion layers at electrodes contacted by an aqueous electrolyte solution. In contrast to related schemes which intermittently discharge a limited portion of battery charge to a load comprising components featuring significant resistance and/or inductance, in this case supercapacitors receive the reversedly pulsed depolarizing discharge.
