The invention discloses a sand
electroless plating metal polar plate and a preparing method thereof. The polar plate comprises
copper plated sand in a graininess shape, resourceful sand serves as the core of the polar plate, optimized sand grains serve as forming carriers, electroless
copper plating is carried out on the surface of the sand after activation and
sensitization to form the
copper plated sand, the reacting
dose participating in a storage battery is used as the criterion of the plating
layer thickness, the copper plated sand is directly packaged or packaged after pretreatment through a packaging bag, a
metal barrier and a packaging box to form the polar plate, and the copper plated sand grains accumulate to form a macroporosity space structure to be applied to the environments of a lead-acid storage battery, an alkaline storage battery and a dry battery as a
current collector. The copper sand is made of the sand through electroless
copper plating, the technology is simple,
conductivity is high after
copper plating, the sand is rich in resource, as the sand grains are different in size, people have many choices when using the sand grains for manufacturing the polar plate, the grain
porosity is large, the pore number per unit area is larger than that of foamy copper, the
plasticity is higher, the manufacturing cost is low, and the sand
electroless plating metal polar plate can be widely used for the technical field of
electrochemistry storage batteries.
