Abstract

The invention discloses a graphene-lead alloy as well as a preparation method and application thereof. The graphene-lead alloy is prepared from the following components in percentage by weight: 0.0015-0.1 percent of graphene, 96.96 percent of lead and any one, two, three or four of 0.1-1.6 percent of tin, 0.015-0.05 percent of aluminum, 0.05-1.2 percent of strontium and 0.05-0.09 percent of copper. The invention also discloses the preparation method and the application to a grid alloy. The graphene-lead alloy used by a grid is high in rigidity, good in toughness, mobility and creep resistance, strong in corrosion resistance and firm in combination of the grid and an active substance without a barrier layer. According to the invention, a battery manufactured by the graphene-lead alloy is little in water loss and long in cycle life.

Description

technical field [0001] The invention relates to the field of graphene alloys, in particular to a graphene lead alloy, a preparation method and an application thereof. Background technique [0002] As we all know, the mainstream grid alloys of lead-acid batteries are divided into lead-calcium series and lead-antimony series. Lead-calcium series include commonly used lead-calcium-tin-aluminum, uncommonly-used lead-calcium-high-tin, lead-calcium rare earth, lead-calcium-bismuth-silver, etc.; lead-antimony series include high-antimony, medium-antimony, low-antimony multi-element, lead-antimony-cadmium positive grids, etc. alloy. Calcium-based and antimony-based alloys have their own advantages and disadvantages: lead-calcium alloys have the advantages of less water loss, small internal resistance, and long-term floating charge resistance, and have been widely used in backup power applications; lead-antimony series are mainly used for high-current discharge occasions and deep c...
