Advantages and Disadvantages of 18650 lithium ion battery cell

　　The working principle of 18650 lithium ion battery cell is the same as that of liquid lithium batteries. The key difference is that the electrolyte of lithium batteries is different from that of liquid lithium batteries. The key structures of rechargeable batteries include positive batteries, negative batteries and electrolysis. Lithium phosphate rechargeable batteries have the advantages of non-toxic, non-polluting, good safety factor, low raw materials, low price, and long service life.

　　Advantages of polymer lithium battery:

　　1. The working standard voltage of a single rechargeable battery is significantly higher than Ni-h and Ni-cd batteries.

　　2. The volume density is greater than or higher than Ni-h rechargeable batteries or Ni-cd batteries;

　　3. Lithium batteries have a short service life and suffer little volume damage after long-term storage.

　　4. The polymer lithium battery has a long life, and the cycle system has a service life of more than 500 times.

　　5. The polymer lithium battery has no memory and does not need to be empty before charging, making it easy to use;

　　6. The safety factor of 18650 lithium ion battery cell is better.

　　Disadvantages of 18650 lithium ion battery cell:

　　1. Increase the cost of 18650 lithium ion battery cell and increase the difficulty of purifying the electrolyte.

　　2. The need to maintain routing control, overcharging or power loss will cause cross-destruction of the internal compounds of the rechargeable battery, thereby causing more serious damage to the life of the rechargeable battery;
