Abstract

The invention discloses a lead-acid storage battery with excellent starting performance and a preparation method of the lead-acid storage battery, the lead-acid storage battery comprises a positive plate, a negative plate, an isolating membrane, an electrolyte and a shell, the positive plate is formed by coating positive electrode lead paste on a positive electrode mesh grid and curing and drying,and the negative plate is formed by coating negative electrode lead paste on a negative electrode mesh grid and curing and drying. The storage battery prepared by the invention has good low-temperature starting performance and long cycle life; compared with a grid formed by casting, the low-temperature starting performance and the cycle durability of the storage battery can be better improved byadopting the pull net type grid in a scientific and reasonable proportion, the superficial area of the grid is increased by adopting the pull net type grid, and lead plaster is prevented from fallingoff, so that the low-temperature starting performance and the cycle durability of the storage battery can be improved. The internal resistance can be reduced to a certain extent, and the utilization rate of active substances can be further increased by reducing the internal resistance and increasing the surface area.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a lead-acid battery with excellent starting performance and a preparation method thereof. Background technique [0002] The starter lead-acid battery is the main member of the lead-acid battery series. All fuel vehicles used in our daily life have a starter lead-acid battery to provide power for starting, ignition, lighting, electrical appliances, etc. In the IEC international standard and GB5008 national standard, the CCA index under the condition of -18°C is the most important performance index of the lead-acid battery used for starting. However, 90% of the usage scenarios in daily life are at room temperature (-5~30°C). In particular, daily use does not have the strict -18°C test conditions. Therefore, people generally use the method of normal temperature detection starting ability (commonly known as: normal temperature CCA, or card meter CCA) in daily use and sa...
