Advantages and disadvantages of lithium titanate batteries
Lithium titanate battery has the advantages of 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 and stable green Environmental protection and other characteristics, so it has a very wide range of application prospects in the field of communication power supply.
The biggest disadvantage of lithium titanate batteries is their low energy density and high cost. In particular, the low energy density is due to the principle and performance of the anode material lithium titanate, and it is difficult to have a big breakthrough. Cost can be reduced through scale, but based on the weakness of the principle, it cannot be changed through technology.
Advantages and disadvantages of lithium iron phosphate batteries
Lithium iron phosphate battery has super long life, the cycle life of long-life lead-acid battery is about 300 times, the highest is 500 times, and the cycle life of lithium iron phosphate power lithium battery reaches more than 2000 times;
It is safe to use. The lithium iron phosphate battery completely solves the potential safety hazards of lithium cobalt oxide and lithium manganese oxide. Lithium cobalt oxide and lithium manganese oxide will explode under a strong collision and pose a threat to consumers’ lives. Lithium has undergone strict safety tests and will not explode even in the worst traffic accidents;
High-current 2C fast charge and discharge, with a dedicated charger, the battery can be fully charged within 40 minutes of charging, and the starting current can reach 2C, but the lead-acid battery does not have this performance now;
High temperature resistance, the peak value of lithium iron phosphate electric heating can reach 350℃500℃, while lithium manganate and lithium cobaltate are only around 200℃.
The tap density of the positive electrode material of lithium iron phosphate battery is relatively small, and the volume of lithium iron phosphate battery of equal capacity is larger than that of lithium cobalt oxide and other lithium ion batteries, so it does not have an advantage in miniature batteries.
