Lithium ion battery has many advantages such as high energy density, high discharge voltage, low battery self-discharge rate, long cycle life, high charge-discharge efficiency, wide operating temperature range, etc. It is widely believed in the industry that lithium ion battery is the most looking forward to becoming the protagonist of energy Internet energy storage system.
Lithium battery solar street lamp is a kind of energy saving, environmental protection, green free from contamination of new energy products. At the beginning, with the continuous development of the lithium battery solar street lamp industry, the scope has been expanded, and the technological skills have been promoted. In the solar street light industry, more and more street light manufacturers choose lithium batteries. In order to improve our understanding of lithium batteries, today xiaobian will invite the company's technical personnel to introduce some basic knowledge of the battery.
The capacity of lithium battery has rated capacity and actual capacity. Quantity refers to the design and manufacturing of the battery to determine or guarantee the battery in a certain discharge premise, should release the minimum amount of electricity.
Li-ion battery at room temperature, constant current (1C) constant voltage (4.2V) control of charging under the premise of charging 3h, the actual capacity of the battery refers to the battery in a certain discharge premise of the actual amount of electricity released, the important discharge rate and temperature (so strictly speaking, the capacity of the battery should specify the premise of charge and discharge).
Common capacity units include mAH and AH (AH=1000mAh).
