The main components of lithium battery electrolyte include solvents, solutes, additives and other raw materials.
The electrolyte is primarily responsible for the conduction of conductive ions between the positive and negative electrodes, but it also plays a key role in energy density, lifespan, power density, safety performance, wide temperature. application, etc. drums. The effect is called blood battery. In battery applications, the electrolyte must meet performance indicators such as high conductivity, good thermal stability, high chemical stability, wide electrochemical window, wide operating temperature range and good safety.
Solvents, solutes, additives and other raw materials are prepared in proportion and under certain conditions. The quality proportions of troThe raw materials are 80 to 85%, 10 to 12% and 3 to 5%, respectively, and the cost proportions are 25 to 30%, 40 to 50% and 10%. 30% respectively.
Identification of lithium batteries
General nickel cadmium batteries are 500 mAh or 600 mAh, and nickel hydrogen batteries do not than 800 to 900 mAh while lithium-ion; Cell phone batteries have a capacity of 1300-1400 mAh, so the lithium battery is fully charged and can be used 1.5 times longer than the nickel-hydrogen battery and about 3.0 times longer long as the nickel-cadmium battery. If you find that the operating time of the lithium-ion cell phone battery you purchased is not as long as advertised or specified in the manual, it may be counterfeit.
The original battery has a uniform wear-resistant surface and isMade of PC material, which is not brittle. Counterfeit batteries do not have a wear-resistant surface or are too rough and are made from recycled materials. are prone to fragility. If a nickel-cadmium or nickel-hydrogen battery pack is used to simulate a lithium-ion cell phone battery pack, it must be made up of five individual cells. The charging voltage of a single battery generally does not exceed 1.55V and total. the battery pack voltage does not exceed 7.75 V. When the total charge voltage of the battery pack is less than 8.0 V, it may be a nickel-cadmium or nickel-hydrogen battery.
