The invention discloses a
nickel-
hydrogen battery capable of being used in a low-temperature environment and a preparation method of the
nickel-
hydrogen battery, and relates to the
nickel-
hydrogen battery and the manufacturing method of the nickel-hydrogen battery. The nickel-hydrogen battery capable of being used in the low-temperature environment comprises a shell, an
anode, a
cathode,
electrolyte and a diaphragm, wherein the
anode, the
cathode, the
electrolyte and the diaphragm are arranged in the shell; the diaphragm isolates the
anode and the
cathode; and the cathode is made of a
cerium-rich or
lanthanum-rich
hydrogen storage alloy. The preparation method comprises the following steps of: A, manufacturing a positive plate and a negative plate; B, eliminating a position for
spot welding of a nickel strap from a center position in the length direction of the anode through ultrasonic
waves, wherein the nickel strap is welded together with a nut cap during subsequent
assembly to serve as a leading-out end of the anode; and C, winding the positive plate, the negative plate and the diaphragm into cylindrical shapes by using a
winding machine, placing the positive plate, the negative plate and the diaphragm into a nickel plated steel shell, and adding the
electrolyte to assemble a battery. When the nickel-hydrogen battery is used in an outdoor environment in winter,
electrical equipment can use the
electric power for a longer time, so that use requirements of customers are met, the cycle life of the nickel-hydrogen battery is long, and the
power performance of the nickel-hydrogen battery is high.
