Abstract
Battery modification directed to problem of reduced withdrawable current capacity of transiently highly-loaded discharging batteries. Prior art batteries reviewed are: two which enhance galvanic reaction during discharge by circulating low-viscosity electrolyte around magnets spaced between electrodes; and one using magnetic material at negative electrodes to limit dendrite formation during battery charging, whether the electrolyte is a liquid solution or solidified by gelling. The present invention is a current collector preferably comprising a magnetized sheet of foamed nickel having North and South poles on opposite faces, and folded about a small coercivity mumetal insert, installing such an assembly as the current collector of any two-sided type plate electrode. A variety of embodiments is disclosed, as are various arrangements combining more than one type embodiment per battery.
