Background

A "lithium battery" is a type of battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a positive/negative electrode material. Lithium metal batteries were first proposed and studied by gilbertn. lewis in 1912. In the 70 s of the 20 th century, m.s.whitetingham proposed and began to study lithium ion batteries. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. With the development of scientific technology, lithium batteries have become the mainstream. Before sulphuric acid is injected, sulphuric acid and water need to be uniformly mixed in equal proportion, and when stirring and mixing are carried out, the device can generate some vibrations, and after long-time work, internal parts are easy to loosen, so that unnecessary damage is caused.
