Novel negative plate used in low temperature environment

Abstract

The invention relates to a novel negative plate used in low temperature environment. The negative plate comprises 2.5-2.9kg of acetylene black, 2-2.8kg of humic acid, 9-12kg of barium sulfate, 1.5-2.5kg of lignin, 1.0-1.5kg of barium stearate, 110-120kg of pure water, 1000kg of lead powder, 850-900g of short fiber and 75-90kg of sulfuric acid, the length of the short fiber is 2-4mm, and the concentration sulfuric acid is 50%. The original formula of the negative plate is changed, and a new formula is adopted, so the usability of a battery is improved, the charging acceptance of the battery used in low temperature environment is improved by 30%, and the usability of the battery at a low temperature of -15DEG C is improved by 25%. The novel negative plate has the advantages of novel formula, simple making, improvement of the usability of the battery, and improvement of the starting performance of a storage battery.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a negative plate of a battery, specifically a novel negative plate for use in a low-temperature environment. Background technique [0002] This year, with the shortage of oil resources and rising prices, the development and use of electric drive vehicles has become the hottest topic today, and the bottleneck restricting the development of electric drive vehicles is the storage battery. Currently, the use of lead-acid batteries occupies an absolute proportion. However, the lead-acid battery has a short cycle life and poor high-current performance, especially when used in a low-temperature environment in winter. The starting performance of the battery is poor. Contents of the invention [0003] In order to solve the above problems, the present invention provides a negative plate of a lead-acid battery used in a low-temperature environment with long discharge time and go...

[0002] This year, with the shortage of oil resources and rising prices, the development and use of electric drive vehicles has become the hottest topic today, and the bottleneck restricting the development of electric drive vehicles is the storage battery. Currently, the use of lead-acid batteries occupies an absolute proportion. However, lead-acid batteries have short cycle life and poor high-current performance, especially when used in low-temperature environments in winter. The starting performance of the battery is poor, and the use time is significantly shorter than that in summer and other high-temperature weather, and the discharge capacity at one time is small.
