The parameter to describe the energy storage size of lithium ion battery is energy density, which is approximately equivalent to the product of voltage and lithium battery capacity in numerical value.

32650 lithium battery is a cylindrical battery, 32mm in diameter, 65mm in height, generally common lithium iron phosphate battery.

Battery bulge will affect the use of mobile phones or digital cameras, in addition to the existence of gas between the battery plate will also affect the capacity of the battery charge and discharge.

Since the size of the 18650 battery is fixed, “18” represents the diameter, “65” represents the height, and “0” represents the cylinder.

Lithium battery is a kind of battery which is made of lithium metal or lithium alloy as negative electrode material and USES non-aqueous electrolyte solution.

Do not use the battery for a long time should be disconnected from the car battery, and interval of time to add some battery power

This paper starts from the charging circuit principle of lithium battery, introduces the design of charging circuit of rechargeable battery on the basis of a deep understanding of the principle of lithium battery

A new energy car with a guideline price of 300,000 yuan may have a battery cost of 100,000 yuan or more.

Generally, 3.7v lithium battery requires “protection plate” with overcharge and over discharge.
