Abstract

The invention provides a lead acid battery and a preparation method thereof, belongs to the field of lead acid battery preparation, and can overcome the defects that the existing lead acid battery is large and is poor in current performance, and cycle life is short. Graphite is added to lead paste of an anode and a cathode of the lead acid battery, activated carbon is added to the lead paste of the anode of the lead acid battery, and the lead acid battery made of the lead paste of the anode and the cathode overcomes the defects that the existing lead acid battery is large and is poor in current performance and cycle life is short.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a lead-acid battery and a preparation method thereof. Background technique [0002] Traffic exhaust emissions and the burning of fossil fuels have had an impact on the climate that cannot be underestimated. With the depletion of oil and other resources, human beings are facing the two urgent problems of environmental protection and rational use of resources. New energy vehicles are approaching the era of hybrid vehicles, and the development of hybrid vehicles with zero exhaust emissions, no pollution, and no noise has broad application prospects. [0003] The core of a hybrid vehicle is a power source, and lead-acid batteries are currently the most widely used storage batteries. However, the high current performance and cycle life of existing lead-acid batteries cannot meet the requirements of hybrid batteries. Contents of the invention [0004] The purpose of the present i...
