Hello, I would like to ask about the difference between 18650 lithium battery 3c and 5c and the curr

The difference is capacity. The 3c and 5c of 18650 lithium battery refer to the discharge rate of the lithium battery, and 1C means discharge at a current of 1 times the capacity. The discharge current of 2000mah 3C lithium battery is 6A, the discharge current of 2200mah 3C lithium battery is 6.6A, and the discharge current of 2000mah lithium battery mah 5C is 10A.

Factors that limit the charging and discharging performance of lithium batteries:

Generally, a conductive agent is added inside the cathode active material to reduce the contact resistance between the active materials and between the active material and the matrix cathode/current collector, and improve the conductivity (ion) of the cathode material and electronic conductivity) to improve the performance ofSpeed. Conductive agents of different materials and shapes will affect the internal resistance of lithium batteries, thereby affecting their performance.

My lithium battery is labeled INR18650A205 A 562131029160. What does this mean?

300W power, powered by 12.6 voltage V, the battery discharge current reaches 24A; 2200 mAh battery It is impossible to normally provide such a large continuous operating current. If this battery is subjected to a load of 12.6V and a power of 300W, it is very likely that the battery will amount to an output short circuit and cause heat, or even damage. There is no point in calculating how long this will last.

INR1865P2200mAh represents the ternary18650 lithium battery, the power type, and thecapacity of the batteryis 2200mAh. ?

INR represents generalment a cylindrical lithium battery made of ternary material. I stands for lithium battery. N stands for ternary material. R stands for cylindrical type. 18650 represents the battery model. P means power type. 2200 mAh represents the battery capacity.

The best 18650 batteries are now made from lithium iron phosphate. For example, the IFR18650P1200mAh battery has a magnification rate between 30C and 60C, and IFR replaces the cylindrical lithium iron phosphate battery.

Lithium batteries are divided into two types: lithium metal batteries and lithium ion batteries.

1. Lithium metal battery

Lithium metal battery generally uses manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the negative electrode material, and uses non-aqueous material. electrolyte solution. The principle of the discharge reaction is: Li+MnO2=LiMnO2.

2. Lithium-ion battery

Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and use non-aqueous electrolytes. The reaction that occurs on the positive charge electrode is: LiCoO2==Li(1-x)CoO2+XLi++Xe- (electrons); the reaction on the negative charge electrode is: 6C+XLi++Xe- = LixC6; the total reaction of the rechargeable battery: LiCoO2+6C = Li(1-x)CoO2+LixC6; .
