How long is the life of a lithium battery.

According to the current technical level of ternary lithium batteries, if used properly, it can be used for at least 5 years on electric vehicles. If used improperly, the 2-3 year lithium battery life will be attenuated.

The so-called use or not, mainly depends on whether you can abide by the principle of shallow filling and shallow, do not overuse.

Introduction:

The ternary polymer lithium battery refers to a lithium battery using a lithium nickel cobalt manganese ternary positive electrode material for the positive electrode material. There are many kinds of positive electrode materials for the lithium ion battery, mainly lithium cobaltate, lithium manganate, lithium nickelate, and ternary materials, lithium iron phosphate and the like. At present, the ternary material battery replaces the widely used lithium cobalt oxide battery, and is widely used in the field of notebook batteries.

Ternary polymer lithium battery parameters:

Nominal capacity: 1250mAh

Standard discharge continuous current: 0.2C

Maximum discharge continuous current: 1C

Product size: MAX9.5*35*52mm

Finished product internal resistance: ≤150mΩ

Lead type: national standard line UL1007/24#, line length 55mm

Protection parameters: overcharge protection voltage / 4.325 ± 0.025V per string

Over-discharge protection voltage 2.5±0.05V

Overcurrent value: 2~6A or 3-8A

Ternary polymer lithium battery performance:

The material with relatively balanced capacity and safety has better cycle performance than normal lithium cobaltate. Its nominal voltage is only 3.5-3.6V in the early stage due to technical reasons. However, there are restrictions on the scope of use, but until now, with the formulation with continuous improvement and perfect structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide battery.

Terpolymer lithium battery status:

SANYO, PANASONIC, SONY, LG, and SAMSUNG have launched batteries for ternary materials. A considerable number of notebook battery lines have replaced the previous lithium cobalt oxide batteries with batteries of ternary materials, SANYO. In the SAMSUNG column battery, the production of lithium cobalt oxide batteries turned to ternary cells was completely discontinued. At present, most of the small high-power batteries at home and abroad use ternary cathode materials.

Lithium batteries have a service life of only two to three years.

Lithium batteries are generally capable of charging and discharging 300-500 times. It is best to partially discharge the lithium battery instead of completely discharging it, and try to avoid frequent full discharges. Once the battery is off the production line, the clock begins to move. Lithium batteries last for only two to three years, whether you use them or not.

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation lithium-metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate and performance price ratio are better than lithium-ion batteries. Due to its own high technical requirements, only a few companies in the country are producing such lithium metal batteries.
