  What are the key technologies of high-temperature Ni-MH batteries?

  Nickel-cadmium (Ni-Cd) batteries have always been one of the battery targets of environmental protection workers because they contain cadmium, a highly toxic element. Organizations such as the European Union continue to issue policies and directives ("Waste Electrical and Electronic Equipment Directive" WEEE and "Restrictions on Electronic and Electrical Equipment")

  Nickel-cadmium (Ni-Cd) batteries have always been one of the battery targets of environmental protection workers because they contain cadmium, a highly toxic element. Organizations such as the European Union continue to issue policies and directives ("Waste Electrical and Electronic Equipment Directive" WEEE and "Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive" RoHS), which has accelerated the process of replacing nickel-cadmium batteries with other batteries. Nickel-metal hydride (Ni-HM) batteries are the most promising alternative. How to deal with the performance problems of nickel-hydrogen batteries in high-temperature environments is the key to whether they can be used in a wider range. In the process of charging and discharging and in the environment of use, nickel-metal hydride batteries will inevitably involve the issue of temperature on battery performance and service life. High-capacity mobile power supplies urgently needed by the military, aerospace, navigation, petroleum, coal, geological exploration and operations, ice And secondary mobile power for mountaineering sports, which has strong strategic significance, scientific value and economic value. In addition, nickel-metal hydride-powered lithium-ion batteries also have important application value prospects in hybrid vehicles such as fuel-powered lithium batteries + nickel-hydrogen batteries (electric-electric hybrids) and gasoline + nickel-hydrogen batteries (oil-electric hybrids).

  During the charging and discharging process of rechargeable batteries, changes in ambient temperature, etc., have an impact on battery performance. Although all battery materials have a certain impact on battery performance, however, as far as high-temperature batteries are concerned, improving and optimizing positive and negative electrode materials is a A better way is to improve the hydrogen storage alloy except for a small number of patent disclosures. The critical technology lies in the positive electrode material, including adding rare earths, rare metals, alkaline earth elements, etc., such as Mg, Ca, Sr, Sc, Y, La, Lanthanides, Ti, Zr, Cr, Mo, W, Mn, Fe, Co, Cu, Zn, Cd, b, Al, Ga, In, Si, p, As, Sb, bi One or more of oxides and hydroxides. Since it is difficult to achieve a complete balance of several materials with different properties when the positive electrode is prepared, it is considered to use coprecipitation to dope the above elements when manufacturing spherical nickel hydroxide, and it is also considered to coat a layer of hydroxides of the above elements on the spherical nickel.
