Abstract

The invention discloses lead-acid storage battery grid lead alloy and relates to the technical field of electrochemistry. The lead-acid storage battery grid lead alloy comprises, by weight, calcium 0.15%-0.18%, tin 1.50%-1.90%, aluminum 0.04%-0.06%, ferrum less than or equal to 0.002%, bismuth less than or equal to 0.005%, zinc less than or equal to 0.001%, antimony less than or equal to 0.001%, silver less than or equal to 0.001%, copper less than or equal to 0.0015%, arsenic less than or equal to 0.001% and the balance lead. The lead-acid storage battery grid lead alloy can solve the problem that storage battery plates are low in mechanical strength and large in internal resistance.

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to an alloy for manufacturing lead-acid storage battery grids. Background technique [0002] Batteries for hybrid electric vehicles are a huge new market for the battery industry. Lead-acid batteries have great advantages when used in hybrid electric vehicles and electric vehicles. They are low in price, stable in voltage, high in safety performance, and have a good manufacturing base. [0003] The core component of the battery is the pole plate, and the performance of the pole plate is directly determined by the grid and lead paste, and the quality of the grid depends on the performance of the grid lead alloy. The quality of the grid lead alloy affects the strength of the grid, and the content of each alloy element in the grid lead alloy has a great influence on the electrical and mechanical properties of the plate. The existing grid lead alloy has defects such as low me...
