Technical Field

The invention relates to the technical field of lithium batteries, in particular to a lithium battery pack for a field solar street lamp.

Background

A "lithium battery" is a type of battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a negative electrode material. Lithium metal batteries were first proposed and studied by Gilbert n. Lewis in 1912. In the 70 s of the 20 th century, m.s.whittingham 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 science and technology, lithium batteries have become the mainstream nowadays. Especially in the application of photovoltaic street lamps.

After the battery pack for the conventional street lamp is installed, the waterproof grade difference exists, the shell is easy to corrode, and the maintenance and replacement difficulty is high.
