Manufacturing method of long-life high-capacity tubular storage battery

Abstract

The invention relates to a manufacturing method of a long-life high-capacity tubular storage battery. The manufacturing method comprises the following steps: firstly, adding basic lead sulfate seed crystals and graphite into 100 kg of lead powder with the apparent specific gravity of 1.20-1.35 g / cm; mixing; then pouring the obtained mixture into a positive tubular plate; then placing the tubular plate into which powder is poured in a diluted sulphuric acid solution to be soaked; after that, curing and drying under the condition of 100% humidity; assembling a positive plate and a negative plate which are processed; adopting a PE separator to wrap the negative plate; processing the wrapped plate via such procedures as welding, through the partition welding, heat sealing and terminal welding to obtain an assembled semi-finished battery; finally, adopting a diluted sulphuric acid internal circulation formation process to perform charging formation on the semi-finished battery.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a method for manufacturing long-life and high-capacity tubular storage batteries. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's material life, batteries have become a necessity in our daily life. At present, lead-acid batteries have become a very widely used chemical "power source". Because it has the advantages of safety, reliability, low price, and wide application range, the output of storage batteries is the largest and the most widely used among various types of batteries. [0003] With the increasing calls for environmental protection, people's awareness of electric vehicles and electric cars replacing diesel and gasoline vehicles to a certain extent is getting stronger and stronger. The market demand for new energy vehicles is growing explosively. The heart of new energy vehicles—— T...

Problems solved by technology

At present, the tubular power batteries used in the market have problems such as low specific energy, short life, and difficulty in charging and discharging, which lead to an increase in the use cost of the battery

Similarly, with the development of communication, electric power and other industries, the demand for tubular batteries for energy storage has also increased geometrically. short and low discharge capacity, which has caused certain difficulties in the market promotion of tubular energy storage batteries

[0004] In view of the above problems, the low specific capacity, poor charge and discharge performance, and short life of tubular batteries have limited the development of tubular batteries. Therefore, the market urgently needs a battery manufacturing method with high specific capacity, long life and good charge and discharge performance. And the manufacturing process replaces the existing tubular battery manufacturing process, increases the market share of tubular batteries, and improves user satisfaction
