摘要

Like other accumulator types Ni-MH batteries are unable to keep high characteristics in the temperature range -30℃ to +40℃. To solve this problem the negative electrode material - intermetallic compound (IMC) hydride - must have dissociation pressure of 0.1-1.5 atm in this temperature interval. The IMC composition was calculated with mathematic model. The model describes dependence of IMC hydrides properties on IMC composition. Using calculation results series of alloys were prepared and their hydrogen absorption and electrochemical properties were studied. The best alloy is CeMn_(0.5)Co_(0.25)Al_(0.5)Ni_(3.75). The sample has discharge capacity 275 mAh/g, keeps 95% of this value at 40℃ and 40% at -30℃.
