Lithium batteries are more and more favored by enterprises. Today, Shenzhen Topband Lithium Battery will share the characteristics of lithium batteries with you!
1. It has higher component energy ratio and volume energy ratio;
2. High voltage, the voltage of single-cell lithium battery is 3.6V, which is equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries;
3. Small self-discharge and long-term storage, which is the most outstanding advantage of the battery;
4. No recall effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so there is no need to discharge lithium batteries before charging;
5. Long life. Under normal operating conditions, the number of charge/discharge cycles of lithium batteries is much greater than 500;
6. Fast charging. Lithium batteries can generally be charged with a current of 0.5 to 1 times the capacity, which shortens the charging time to 1 to 2 hours;
7. Can be used in parallel at will;
8. Since the battery does not contain heavy metal elements such as cadmium, lead, and mercury, it has no pollution to the environment and is the most advanced green battery in contemporary times;
9. High cost. Compared with other rechargeable batteries, lithium batteries are more expensive.
The structure of lithium battery
Lithium batteries generally have two shapes: cylindrical and rectangular.
The interior of the battery adopts a spiral wound structure, and a very precise and highly permeable polyethylene film is used to separate the material between the positive and negative electrodes. The positive electrode includes a lithium ion collector composed of lithium and cobalt dioxide and a current collector composed of an aluminum thin film. The negative electrode is composed of a lithium ion collector composed of sheet carbon materials and a current collector composed of a copper film. The battery is filled with an organic electrolyte solution. Others are also equipped with safety valves and PTC components to protect the battery from damage when the battery is in an abnormal state and the output is short-circuited.
The voltage of a single-cell lithium battery is 3.6V, and the capacity cannot be infinite. Therefore, the single-cell lithium battery is often processed in series and parallel to meet the requirements of different occasions.
