Use (discharge) precautions
For batteries, normal use is the process of discharging. Need to pay attention to the discharge of lithium battery:
First, the discharge current should not be too large. Excessive current causes heat inside the battery, which may cause permanent damage. On the mobile phone, this is no problem, you can not consider it.
As can be seen from the image on the right, the larger the battery discharge current, the smaller the discharge capacity and the faster the voltage drop.
Second, you must never over discharge! Lithium battery internal storage of electrical energy is achieved by a reversible chemical change of electrochemistry. Excessive discharge will cause irreversible reaction of this chemical change, so lithium battery is most afraid of overdischarge, once the discharge voltage is lower than 2.7V, May cause the battery to be scrapped. Fortunately, the inside of the mobile phone battery has been installed with a protection circuit, the voltage is not low enough to damage the battery, the protection circuit will work, stop discharging.
Advantages of carbon coated aluminum foil in lithium ion battery applications
1. Suppress battery polarization, reduce thermal effects, and improve rate performance;
2, reduce the internal resistance of the battery, and significantly reduce the dynamic internal resistance increase of the cycle;
3. Improve consistency and increase battery cycle life;
4. Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece;
5. The protective current collector is not corroded by the electrolyte;
6. Improve the processing properties of lithium iron phosphate and lithium titanate materials.
