The invention discloses a manufacturing method of a high-power nickel-hydrogen battery capable of being used in different temperature environments. A product is mainly suitable for the high-power nickel-hydrogen battery capable of being used in different temperature environments. According to the technical scheme, a battery cathode material is formed by electrically coating spherical Ni(OH)<2> which has high-rate discharge performance at a high temperature and a low temperature with 8%-10% of Co and then adding titanium dioxide used for improving the high-temperature charging efficiency; a battery anode material is formed by adding 4.38% of MmNi, 0.46% of Co, 0.11% of Mn, 0.3% of Al and 0.05% of Mg to an alloy material of an Mg element with reactive high-temperature and low-temperature environment reaction; and a low-temperature active material is added to an electrolyte. A nickel screen with superconducting ability through high-temperature ageing and high-rate charging and discharging is formed on a negative electrode; and high-rate discharging of the battery in a temperature environment of -45 DEG C to 85 DEG C can be achieved, so that the high-rate working current of the nickel-hydrogen battery at different environment temperatures is improved.
