What are the reasons for the safety of lithium iron phosphate batteries?

[DelJocelyn]

Lithium iron phosphate batteries are safe because the PO bond in the lithium iron phosphate crystal is stable, difficult to decompose, and does not collapse, generate heat, or form strongly oxidizing substances under high temperatures or overcharging. The advantages of lithium iron phosphate batteries are: 1. Long lifespan; 2. Safe to use; 3. Fast charging; 4. High-temperature resistance; 5. Large capacity; 6. No memory effect; 7. Environmentally friendly. The disadvantages of lithium iron phosphate batteries are: 1. Low tap density of the cathode material; 2. Poor conductivity; 3. Poor low-temperature performance.
