18650 high capacity lithium battery voltage and main parameters

by:dcfpower     2020-11-24

18650 lithium battery voltage and capacitance of the specifications of battery is the most important performance indicators, also is the key to affect the price of lithium battery elements, like technology, our factory can design the difference between the capacity of 18650 lithium-ion batteries, which affected by the material and technology, customers have special requirements such as to develop customized, we can also do battery research and development work.

18650 lithium batteries main parameter

18650 lithium batteries is the battery model based on the dimensions to be named, said so, as 18650 lithium batteries the appearance of one of the main parameters is almost the same size. Considering the 18650 lithium batteries and divided across the electrodes in fact can be attributed to the difference between cobalt acid lithium, manganese acid lithium, ternary material, lithium iron phosphate four standard system, remove the lithium iron phosphate, the other three materials can replace each other in essence.

18650 lithium battery voltage is 18650 of lithium-ion batteries is important one of the main parameters, mastering 18650 battery voltage of professional knowledge, a relatively scientific and rational 18650 battery charge and discharge and idle security have vital functions, the following is our three. 7 v5200mahpos machine 18650 ternary lithium battery pack main parameters in detail! !

charging current: standard charge: 0. 2 c, quick charge: 1 c

charging time: standard charge: 5. 5 ~ 6. 5 h, quick charge: 1 ~ 1. 5 h

maximum charging current: 1 c

standard point discharge current: constant current: 0. 2 c cut-off voltage: 3. 0 v

maximum point discharge current: 2 c

operating environment: charging: 0 ℃ ~ 45 ℃ Max. 90% RH, point discharge: - 10℃~ 60℃max。 90% RH

lithium electricity protection, overcharge protection, discharge protection, point discharge over-current protection, short-circuit protection point discharge, etc.

point discharge cut-off voltage: 3. 0 v

section 18650 lithium battery pack voltage main parameters below

a, 18650 lithium battery pack voltage standard is the key to working voltage, also called nominal voltage, 3. 7 v, this is the equivalent of three concatenated nickel cadmium or nickel metal hydride batteries, there is a certain battery manufacturer in mainland China standard voltage of 3 design work. 6V。

2, charging limited working voltage: this is the maximum limited, relative to 18650 battery voltage is 4. 2 v, 18650 lithium batteries link is to 18650 battery voltage by 3 at work. 7 v up to 4. 2 v link, link end, express the battery is full charge. Beyond the 4. 2 v, is the overcharge, can produce damage to the battery.

three, finish working point discharge voltage: 18650 lithium battery voltage reduced to minimum standard of work doesn't fit again again point discharge voltage, to 2. 75 v, if the battery on the end of working voltage, of the following is put, discharge will make 18650 battery electrode structure, irreversible reaction in the lithium ion, serious affect 18650 battery life.

18650 lithium battery pack electric capacity?

18650 lithium battery electric capacity is that many manufacturing customers and individual customers, that is largely because, 18650 lithium battery, the greater the capacitance is used, the longer the time to provide customers with more power, but under the same standard system, 18650 lithium battery pack negative functions of high capacitance will bring high prices, so the electric capacity and price stable equilibrium is very crucial.

18650 mAh lithium battery electric capacity distribution in 1500 to three thousand between mAh, but more mature technical is in commonly 1800 mAh to 2600 mAh, this is largely because, 18650 lithium battery pack capacity is too low, can affect the battery working time regulation, effectively shortcomings on the scope of application. While 18650 lithium battery capacity is too high, cost is larger, and the more specific industry of high capacity lithium battery 18650 meaning also is not very big.
