The company production of lithium battery which runs?
1. 18650 3.7V capacity lithium battery, the single capacity of up to 3400mAh, widely used in notebook computers, mobile power, a variety of portable electronic devices
2.18650 3.7V power lithium battery, single capacity up to 3000mAh, meet the 10C discharge, widely used in power tools, electric vacuum cleaners, electric vehicles, etc.
3. Polymer lithium battery, a single capacity of 50mAh~10000mAh, can be customized for any size, widely used in Bluetooth equipment, smart home, lamps, beauty equipment, GPS, etc.
Protection circuit for lithium battery
1.Because of its own characteristics, the ion battery needs to add protective circuit. The protection board is to ensure the safety of the overcharge and discharge state, and to prevent the deterioration of the characteristics.
2.Lithium battery protection circuit is composed of IC and two MOSFET power protection, the protection of IC to monitor the battery voltage to the power switch to the MOSFET plug-in to protect the battery when charging and discharge state, the protection function of IC overcharge protection, over discharge protection and overcurrent / short-circuit protection
How to use lithium ion battery correctly
1.Charge according to the standard time and program, even the first three times
2.When the machine power is too low, it should start charging as soon as possible
3.Lithium battery activation does not require special methods, in the normal use of the machine, the lithium battery will naturally activate
4.The use of lithium ion batteries should pay attention to fire prevention and waterproof, when the machine is not used for a long time, should take the lithium battery, placed in the dry, low temperature place to properly keep, in order to prevent and avoid the use of lithium batteries caused by improper family fire accidents
What are the components of a lithium-ion battery?
1.Upper and lower cover of battery
2.Positive electrode active material is lithium cobalt oxide
3.Diaphragm -- a special composite membrane
4.Negative electrode active material is carbon
5.Organic electrolyte
6.Battery shell (divided into two kinds of steel shell and aluminum shell)
7.Protective plate (preventing overcharge, over discharge and short circuit protection)
Compared with Ni MH battery, what are the advantages of lithium ion battery?
1.The working voltage is 3.7V, Ni MH battery is only 1.2V, and the energy density is high. High energy density means that batteries of the same size store more energy. Let me put it another way，
High energy density lithium ion batteries can reduce the volume of the battery itself and its related products
2.High power density, high power density means that batteries of the same size offer higher real-time power. In other words, the high power density lithium ion battery can reduce the volume of the battery itself and its related products
3.With faster battery charging capability, lithium-ion batteries must charge and store before transporting electric energy, and the charging process takes a relatively short time, which makes the terminal users more convenient to use
4.Up to 500-1000 cycles of charge / discharge can be carried out
5.Lithium ion battery plus protective circuit, the battery pack is more free than the combination of nickel and hydrogen, string and more flexible
