Lithium battery technology

ternary lithium battery

The three elements of the ternary lithium battery are called "nickel", "cobalt" and "manganese", and the formulas are 111, 523, and 811 respectively, representing the percentage of these three elements in the battery:

• 111 is 33.33% each
• 523 is 50% nickel, 20% cobalt, 30% manganese
• 811 is 80% nickel, 10% cobalt, 10% manganese

The higher the nickel content, the higher the battery life, the higher the cobalt content, the more battery cycles, the higher the manganese, and the more stable the battery. However, cobalt and manganese are both precious metals and the cost is high, so most ternary batteries on the market areThey all use the formula 811, which seems to have more battery life and low cost, but nickel is an active element and is very unstable. Extrusion, puncture, soaking in water, high temperature, and high nickel materials start to decompose and release at about 200°C.Oxygen, causing detonation.See clearly, it is deflagration, explosion + burning!Moreover, once the nickel burns, there is currently no fire extinguishing method that can extinguish him, only to let him burn out and extinguish itself!The fire brigade is useless, at most it is to pull the security cordon.
