　　Advantages and Disadvantages of lithium ion battery cells 18650

　　Lithium titanate ion battery has small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charge and discharge, long cycle life, wide working environment temperature range, safe, stable and green Environmentally friendly and other characteristics, it has very broad application prospects in the field of communication power supply.

　　The biggest disadvantages of lithium ion battery cells 18650 are low energy density and high cost. In particular, the low energy density is due to the principle performance of the negative electrode material lithium titanate, which makes it difficult to make a big breakthrough. Costs can be reduced through scale, but fundamental weaknesses cannot be changed through technology.

　　Advantages and Disadvantages of Lithium Iron Phosphate Batteries

　　The lithium iron phosphate battery has an ultra-long life. The cycle life of the long-life lead-acid battery is about 300 times, with a maximum of 500 times. The cycle life of the lithium iron phosphate power lithium battery reaches more than 2,000 times;

　　Safe to use, lithium iron phosphate ion batteries completely solve the safety hazards of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganate will explode under strong collisions, posing a threat to consumers' lives, while iron phosphate batteries Lithium has undergone rigorous safety testing and will not explode even in the worst traffic accidents;

　　High-current 2C fast charge and discharge. With a special charger, the battery can be fully charged within 40 minutes, and the starting current can reach 2C. However, lead-acid batteries currently do not have this performance;

　　High temperature resistance, lithium iron phosphate electric heating peak can reach 350℃500℃, while lithium manganate and lithium cobalt oxide are only around 200℃.

　　The tap density of the cathode material of lithium iron phosphate batteries is small, and the volume of lithium iron phosphate batteries of the same capacity is larger than that of lithium ion batteries such as lithium cobalt oxide, so it does not have an advantage in micro batteries.
