Currently, fast charging has become a new label for measuring battery performance。 It is particularly important in the new energy vehicles, AGV industry。
Except to improving the charging rate, the fast charge battery technology should also consider the energy density, life, price, safety and other features,so which power battery would stand out?
1。 Lithium titanate Power Battery:
Lithium titanate Power Battery is named as anode material, and the cathode is made of ternary material. From the performance, the low temperature performance of lithium titanate battery is superior, the safety and the circulation use performance is good, as fast charging pool's magnification performance also obtains the industry affirmation. However, the problem of lithium titanate has two points: firstly, the energy density is relatively low. Second, by the high cost of raare metal materials such as titanium, nickel, cobalt, lithium titanate battery cost is significantly higher than other systems.
2。 Lithium manganese oxide(LiMn2O4) fast charging power battery:
Lithium Manganese oxide battery has the characteristics of power performance, good discharge rate performance, good low temperature performance, high voltage frequency, and the cost advantage of LiMn2O4 is being gradually highlighted when ternary raw material rising rapidly. However, the disadvantage of using this kind of positive material is also obvious, first, the cycle life is not long enough, in addition, in energy density, high temperature performance, etc. still need to improve, and need to continue to test through practices.
3. Lithium iron phosphate(LiFePo4) fast charging battery:
Lithium iron phosphate Fast charge battery is developed with the most mature technology of lithium iron phosphate system , material costs are relatively low, combined with the mature technical background and stable product performance, lithium iron phosphate fast rechargeable battery development potential is enormous。
