Abstract

The invention discloses cathode diachylon used for a power-type lead-acid storage battery, comprising the following components: 100kg of lead powder, 0.10-0.12kg of short fiber, 0.40-0.60kg of humic acid, 0.12-0.30kg of sodium lignin sulfonate, 1.00-2.00kg of acetylene black, 1.00-1.50kg of conduction graphite, 2.00-3.00kg of activated carbon, 0.60-1.00kg of barium sulphate, 15000-22000g of deionized water and 7200-6000ml of sulfuric acid with the concentration of 1.30-1.40g/cm<3>(25 DEG C). The cathode diachylon has the beneficial effect that the power-type battery produced by the cathode diachylon has the advantages of high specific energy and good large current discharging capability, the low-temperature volume and cycle life are obviously improved.

Description

technical field [0001] The invention relates to a lead-acid battery, in particular to a negative electrode lead paste for a power-type lead-acid battery and a manufacturing method thereof. Background technique [0002] With the advent of the new energy era, the discovery of electric vehicles (including hybrid and pure electric power) is changing with each passing day. At present, the heart of electric vehicles, the power part-battery, has become the focus of attention in the electric vehicle industry, and the safety of lithium batteries Under the condition that the cost performance has not been effectively solved and other chemical power sources cannot be effectively civilized, lead-acid batteries have become the largest and most practical power source for users. [0003] Lead-acid batteries have changed from conventional standby use and low-current and low-power methods to high-current, high-power use methods, facing the dilemma of low specific energy and short life. At pre...
