What is the charging current limit of an 18650 lithium battery?

Usually referring to 3C and 5C, most of 10c is the battery capacity rate.

For example, for our commonly used 2000 mAh lithium battery, if we need a discharge rate of 3C, that is, a lithium battery Normal lithium 2000 mAh has a theoretical maximum discharge of 6A. This is just a simple example.

The average 18650 lithium battery should be below 3C, but the high rate can be 10 degrees Celsius or even 20 degrees Celsius. For most of us who are new to the lithium battery industry, we can simply and roughly understand this C as explosive energy. The greater the burst C, the greater the conversion of energy supplied in the short term.

Tips for proper storage and use of 18650 lithium battery: The storage temperature range of 18650 is 0℃ to +60℃, the temperatureOperating temperature: -20℃ to 50℃ and the optimum operating temperature is 20℃. -40℃. 60 degrees is the temperature that guarantees battery life. High temperatures will shorten battery life. Generally, 130 degrees will burn or explode.

Tips for properly charging and using 18650 lithium battery: The charging temperature of 18650 lithium battery is between 0℃ and +45℃. The safe working voltage range of 18650 lithium battery is 2.8-4.2V. may be lower or higher than this voltage. The lithium ions in the range's batteries become very unstable and can even cause accidents. To ensure the battery is within a safe range, specialized chargers are required to automatically adjust the charging method based on the current condition of the battery.

1. The operating current of the lithium batterym iron phosphate is generally 1C, the maximum is 15C.

2. Charging current is the same as operating current, generally 1C, the maximum is 15C.

3. The general operating voltage of standard lithium iron phosphate batteries is 3.2V; the maximum operating voltage is 3.65V.

Lithium iron phosphate:

Lithium iron phosphate electrode material is mainly used in various lithium-ion batteries. Since the Japanese NTT first revealed the olivine-structured lithium battery cathode material of AyMPO4 (A is an alkali metal, M is a combination of CoFe: LiFeCoPO4) in 1996, John B. Goodenough of the 'Texas State University in the United States in 1997 and others. research groups also subsequently reported the reversible transfer and desorption of lithium characteristics from LiFePO4.

The United States and Japan have publishedcoincidentally the structure of olivine (LiMPO4), which attracted great attention to this material and caused extensive research and rapid development. Compared with traditional lithium-ion secondary battery cathode materials, LiMn2O4 spinel structure and LiCoO2 layered structure, LiMPO4 has wider sources of raw materials, is cheaper and has no environmental pollution.

Lithium iron phosphate battery:

Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium ion batteries mainly include lithium cobalt oxide, lithium manganate and nickel.Lithium acid phosphate, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material currently used in most lithium-ion batteries.
