Battery refers to the part of the space in which an electrolyte solution and a metal electrode are generated to produce a current, a slot, or other container or a composite container. With the progress of science and technology, the battery can produce small electric device can refer to the. Such as solar cells. The performance parameters of the battery mainly include electric potential, capacity, specific energy and resistance.

(1) open circuit voltage of the battery

(2) the internal resistance of the battery

(3) working voltage of the battery

(4) charge voltage

Charge voltage refers to the two time when the battery is charged, the external power supply and the voltage at the two ends of the battery. The basic method of constant current charging and constant voltage charging charging. Constant current charging, which is characterized by the constant current charge in the process of constant. With the charge, the active material is recovered, the electrode reaction area is reduced, and the polarization of the motor is gradually increased.

(5) battery capacity

Battery capacity refers to the amount of power received from the battery, commonly used C said, the unit commonly used Ah or mAh said. Capacity is an important indicator of battery power. Battery capacity is generally divided into theoretical capacity, actual capacity and rated capacity.

The capacity of the battery is determined by the capacity of the electrode, and the capacity of the battery is determined by the size of the electrode, but it is not the sum of the positive and negative capacity.

(6) the storage performance and life of the battery

One of the main characteristics of the chemical power is that it can emit electricity when using it. The so-called storage performance for the two time for the battery to maintain the ability to charge.

For two batteries, the battery performance is an important parameter to measure the performance of the battery. The two battery after a charge and discharge, known as a cycle (or a cycle). Under a certain charge and discharge system, the battery capacity of a specified value before the battery can withstand the charge and discharge times of the battery charge and discharge times, known as the use of the two battery cycle. Lithium ion battery has good storage performance and long cycle life.
