热电池用氯化镍正极材料研究OA北大核心CSTPCD

Using the sublimated nickel chloride as the raw material,the nickel chloride cathode mate-rials were prepared through different carbon material doping processes and assembled into the bat-teries.The nickel chloride cathode materials prepared by graphene coating has the best electrical per-formance.In the matching experiment of graphene-coated nickel chloride cathode materials and dif-ferent types of membranes,the ternary all-lithium membrane and high conductivity membrane have the best matching properties with the nickel chloride cathode materials.The graphene-coated nickel chloride cathode matched with the ternary all-lithium membrane has better power characteristics than the sulfide cathode.Compared with the sulfide cathode,the nickel chloride cathode has a higher voltage platform.At 1 000 mA/cm2 pulse current,the power of the battery with the nickel chloride cathode is about 20%higher than that of the battery with the sulfide cathode,and the nickel chloride cathode is more suitable for the short-time high-power thermal batteries.
