Abstract
The invention relates to a cathode material of nickel-hydrogen battery, which comprises nanometer copper oxide. It adds 3-10wt% nanometer copper oxide (the content of Cuo is 100%) into the cathode AB5 or AB2 hydrogen storage alloy powder of nickel-hydrogen battery to be mixed uniformly; and adds a little of 1wt% PTFE (polytetrafluoroethylene) adhesive to be mixed again. The invention has simple preparation process, lower quantity, high electrode property, high specific power and specific capacity and lower cost.
Description
(1) Technical field [0001] The invention relates to a material, in particular to a battery electrode material. (2) Background technology [0002] MH / Ni battery is a kind of high-energy and environment-friendly "green energy". It has significant advantages such as high specific energy, high specific power, long life, and no pollution. It is an ideal choice for power batteries for electric vehicles. Among the performance parameters of power batteries, specific power and specific energy are important indicators to determine the quality of batteries. There are two ways to improve the specific power and specific energy of the battery: one is to improve the performance of the battery, and the other is to reduce the quality of the battery. The current methods all focus on the first way, that is, to improve the performance of the battery through some treatments and additives. For example, the commonly used methods include adding various additives to the positive electrode of the b...
