Problems solved by technology

The start-stop battery is one of the core basic components of the car start-stop system. The start-stop battery usually uses a lead-acid battery, but the traditional lead-acid battery is prone to sulfation due to the negative electrode in a partially charged state, resulting in battery Early failure, can not meet the requirements of use well

Embodiment 1）

[0015] A lead-carbon start-stop storage battery for automobiles belongs to the technical field of lead-acid storage batteries. The battery adopts AGM side-by-side structure, the shell material is made of high-strength and high-temperature-resistant PP material, the side thickness is increased, and the deformation resistance strength is strengthened; the grid adopts a current-simulating radial structure, and the current distribution is more uniform; the negative electrode paste is added with composite carbon material ( Activated carbon 1.0%~4.0%, conductive carbon black 0.5%~3.0%, graphene 0.5%~2.0%). The rest of the process borrows the current lead-acid battery technology to make 20 sample batteries of 12V60Ah. The formation adopts the internalization process. After the battery is offline, it is left to stand for 72 hours, and 3 are randomly selected from the sample for the charge acceptance test, and 1 is subjected to high temperature. Life cycle test, 1 only for start-stop l...

Abstract

The invention relates to an automobile lead carbon start-stop storage battery, and belongs to the technical field of a lead-acid storage battery. The battery adopts an AGM side-by-side structure, anda high-strength and high-temperature-resistant PP material is adopted as the shell material, so that the side surface thickness is increased and deformation resistant strength is improved; a grid adopts a current simulation radial structure, so that more uniform current distribution can be achieved; and negative electrode lead paste is added with a composite carbon material (1.0-4.0% of active carbon, 0.5-3.0% of conductive carbon black and 0.5-2.0% of graphene). The charging accepting performance and the high-temperature cycle life of the battery are improved and prolonged; and the start-stopcycle life is greater than 200,000 times, so that the problems of high temperature resistance and short start-stop cycle life of the existing storage battery are solved, and the lead carbon start-stop storage battery is applicable to a storage battery for automobile start and stop.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a lead-carbon start-stop battery for automobiles. Background technique [0002] The automobile industry is my country's basic industry. In recent years, my country's automobile industry has developed rapidly, and the total production and sales volume has continued to grow. The average annual sales volume of automobiles exceeds 20 million, and the number of vehicles in stock exceeds 160 million. According to statistics, more than 70% of the annual new oil consumption is consumed by new cars. Therefore, accelerating energy conservation and emission reduction in the automobile industry has become the top priority of my country's energy conservation and emission reduction work. [0003] Because the start-stop system has a good fuel-saving effect, and the cost is relatively low (about 500-3,500 yuan according to its complexity) under the condition of not changing the stru...
