Abstract

The invention discloses a cadmium free lead-antimony grid alloy for traction batteries. The lead-antimony alloy contains antimony, mischmetal and lead and the weight percentage of the antimony in the lead-antimony alloy is 0.5 to 4.5 percent, that of the mischmetal is 0.05 to 2 percent and the rest is the lead. The grid alloy adds rare earth elements into the lead-antimony alloy and causes the grains of the alloy to become small and even, thereby solving the problem of the hot cracking of the lead-antimony alloy and obviously improving and increasing the toughness, aging strength and corrosion resistance of the alloy. Meanwhile, the adding of the rare earth obviously inhibits the growth of the Pb(II) oxide film and reduces the impedance thereof, thus improving the charging and discharging performance and the deep circulation of the battery. Batteries for electric vehicles combined by lead-acid battery grids produced by the alloy have the advantages of corrosion resistance, deep circulation, high-current discharge and long service life.

Description

Technical field:

[0001] The invention relates to the field of metallurgy, in particular to a lead-antimony alloy, in particular to a cadmium-free lead-antimony grid alloy for traction batteries. Background technique:

[0002] Lead-antimony alloy grids are widely used in traction batteries for electric vehicles. However, the lead-antimony alloy is easy to crack and has poor toughness, which makes the battery poor in corrosion resistance, shallow in cycle and short in life.

[0003] At present, many domestic electric bicycle batteries generally use lead-cadmium-antimony alloys. However, cadmium is a toxic element, and products containing cadmium are gradually restricted at home and abroad, which also limits the application prospects of lead-cadmium-antimony alloys. Invention content:

[0004] The object of the present invention is to provide a cadmium-free lead-antimony grid alloy for traction batteries. The rare-earth lead-antimony alloy should solve the problem that the l...
