C: The ratio used to represent the magnitude of battery charging and discharging current, also known as the rate. Charge and discharge rate=charge and discharge current/rated capacity. For example, for a 1200mAh battery, 0.2C represents 240mA (0.2 rate for 1200mAh), and 1C represents 1200mA (1 rate...

C: The ratio used to represent the magnitude of battery charging and discharging current, also known as the rate. Charge and discharge rate=charge and discharge current/rated capacity.

1. Lithium metal battery:

Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and non-aqueous electrolyte solutions.

2. Basic principles of lithium-ion batteries

Discharge reaction: Li+MnO2=LiMnO2

3. Lithium ion battery

Lithium ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and non-aqueous electrolytes. Total reaction of rechargeable battery: LiCoO2+6C=Li (1-x) CoO2+LixC6

Time rate

Hourly rate: It is a discharge rate expressed in terms of discharge time, which is the time it takes to discharge a certain current to the specified termination voltage. For example, if a battery has a rated capacity of 20 hours and the rate is 12AH, which is expressed as C20=12AH, then the battery should be discharged at a current of 12/20=0.6A. If it continues to reach 20H, it is considered qualified. It indicates that the articles published on this website are all from the Internet. If there is infringement, please contact to delete.
