Description

technical field [0001] The invention relates to a nickel-hydrogen power capacitor battery in which a capacitor and a battery are bisexual inline, and in particular to a nickel-hydrogen power capacitor battery having both the characteristics of a super power capacitor and a nickel-hydrogen power battery. Background technique [0002] At present, power batteries mainly include lead-acid power batteries, nickel-metal hydride power batteries, lithium-ion power batteries, super capacitors, etc. Lead-acid batteries are safe, reliable, and low in cost, but there are hidden dangers of lead pollution and low power density. Although the specific energy of lithium-ion power batteries is high, the potential safety hazards are always difficult to completely solve. Although nickel-hydrogen and nickel-cadmium power batteries have good safety and high power density, nickel-cadmium batteries are prone to cadmium pollution and have a strong memory effect. Ni-MH power batteries have a high se...
