A
nickel-
metal hydride storage battery comprises a shell, an
electrode and
electrolyte, the
electrode comprises a positive
electrode plate, a negative electrode plate and a diaphragm, the electrode is completely immersed in the
electrolyte, materials of the positive electrode plate comprise a positive active material, a positive conductive agent, a positive additive and a positive
adhesive, the positive active material comprises
nickel hydroxide, the positive conductive agent comprises
cobalt or
nickel, the positive electrode additive comprises
calcium hydroxide or
zinc oxide, the positive electrode plate
adhesive comprises
carboxymethyl cellulose or
polytetrafluoroethylene, the negative electrode plate is prepared from
hydrogen storage
alloy powder, a negative electrode conductive agent, a negative electrode additive and a negative
electrode adhesive, the negative electrode conductive agent comprises conductive carbon or nickel
powder, the negative electrode additive comprises
zinc oxide or aluminum
oxide, the negative
electrode adhesive comprises hydroxypropyl
methyl cellulose and
butadiene styrene rubber, lining plates are arranged on the outer sides of the positive electrode plate and the negative electrode plate respectively, the lining plates are made of elastic materials, and a plurality of through holes are further formed in the lining plates. The invention provides a novel nickel-
metal hydride storage battery which is safe, reliable, environment-friendly,
pollution-free, long in service life, good in wide-temperature performance and large in capacity ratio.
