CR1220 battery

　　Advantages of CR1220 battery

　　CR1220 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, safety, stability, green and environmental protection and other characteristics, so it has very broad application prospects in the field of communication power supply.

　　CR1220 battery is a lithium titanate used as a negative electrode material for lithium ion batteries. It can be combined with lithium manganate, ternary materials or lithium iron phosphate and other positive electrode materials or lithium ion secondary batteries. In addition, it can also be used as a positive electrode and a lithium secondary battery composed of metallic lithium or lithium alloy negative electrode. The working voltage of CR1220 battery is greater than 2C charging current. In 2-3 years, lithium titanate material will definitely become the anode material of the new generation of lithium-ion batteries and be widely used in new energy vehicles, electric motorcycles and applications requiring high safety, high stability and long cycle.

　　Advantages of CR1220 battery:

　　1. Good safety and stability: Once the traditional carbon electrode is overcharged after lithium is embedded, metallic lithium is easy to precipitate on the surface of the electrode, and its reaction with the electrolyte will produce flammable gas, posing safety risks. The electric potential of lithium titanate is higher than that of pure metal lithium, and it is less likely to produce lithium dendrites. The discharge voltage is stable, and therefore the safety performance of lithium batteries is improved.

　　2. Fast charging performance: Compared with carbon negative electrode materials, CR1220 battery packs have a higher lithium ion diffusion coefficient and can be charged and discharged at high rates.

　　3. Long cycle life: Compared with the current lithium iron phosphate battery pack that can be used for up to 5 years with slow charging and 2 years with fast charging, lithium titanate batteries have very outstanding advantages.

　　4. Good wide-temperature resistance: The spinel structure of the CR1220 battery has a three-dimensional lithium ion diffusion channel, so the CR1220 battery also performs very well in high and low temperature performance. The CR1220 battery has good wide-temperature resistance and is durable. It has strong resistance and can be charged and discharged normally from minus 50℃ to above zero 60℃.

　　Disadvantages of CR1220 battery:

　　1. Compared with other types of lithium-ion power batteries, the energy density is lower.

　　2. The problem of flatulence has always hindered the application of lithium titanate batteries.

　　3. Compared with other types of lithium-ion power batteries, the price is relatively high.

　　4. There are still differences in battery consistency, and the differences in battery consistency will gradually increase as the number of charges and discharges increases.
