Abstract

The invention discloses a manufacturing method of a lead storage battery special for high-voltage express delivery, which overcomes the problems of short service life, small specific energy and long charging time of a lead storage battery in the prior art, and comprises the following steps: preparing a battery shell, and pre-burying a pole nail for conducting two single cells on the battery shell before injection molding; preparing a positive electrode plate and a negative electrode plate; assembling the battery shell, the positive electrode plate, the negative electrode plate, the AGM partition plate and the AGM diaphragm paper into a single battery; and assembling the plurality of single batteries into a finished battery. The invention further provides a lead storage battery special for high-voltage express delivery. The battery is long in service life, short in charging time and large in specific energy, energy consumption caused by the weight of the battery of the electric vehicle is reduced, and therefore the overall performance of the electric vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of lead storage batteries, in particular to a special lead storage battery for high-voltage express delivery and a manufacturing method thereof. Background technique [0002] Lead-acid battery is one of the most widely used batteries at present. Its development has lasted more than 150 years since the 19th century, and its application fields are very wide. In recent years, electric vehicles have developed rapidly in my country due to their better mobility performance, lower storage space requirements and excellent price advantages. At present, 90% of urban electric transportation vehicles such as express electric vehicles use lead-acid batteries produced by traditional techniques. Lead storage battery is a reversible DC power supply, which can convert chemical energy into electrical energy, and also convert electrical energy into chemical energy. The current lead-acid battery is mainly compo...
