Abstract

The invention discloses a beryllium-copper alloy battery probe for a new energy automobile and a processing technology thereof, and particularly relates to the technical field of battery probes. The beryllium-copper alloy battery probe comprises beryllium, zirconium, nickel, copper and a surface treating agent. The conductive performance of the beryllium-copper alloy battery probe can be effectively enhanced, the low-temperature performance of the probe can be effectively improved, meanwhile, it is guaranteed that the probe keeps good conductive performance at a low temperature, and then the power supply stability of an automobile battery is guaranteed. The zirconium metal is added into beryllium-copper alloy so that grains of the beryllium-copper alloy can be effectively refined, and the strength of the beryllium-copper alloy is further improved. Nano-silver particles and nano-zinc oxide particles can be formed, CVD processing treatment is carried out, graphene is formed on the surface of copper alloy foil, the nano-zinc oxide particles are reduced to form nano-zinc, nano-silver and the nano-zinc are doped into the graphene, the conductivity of the graphene can be effectively enhanced, and the graphene is embedded into the copper alloy foil. The conductive performance of the copper alloy foil can be effectively enhanced, and the low temperature resistance of the copper alloy foil can also be effectively enhanced.
