In terms of shape, they can be divided into soft-pack batteries, cylindrical batteries and square hard-shell batteries. Its nominal voltage can reach 3.6-3.8V, with relatively high energy density, high voltage platform, high tap density, long cruising range, large output power, poor high temperature stability, but excellent low temperature performance and relatively high cost.
What is a ternary lithium battery? The full name of a ternary lithium battery is "ternary material battery", which generally refers to the use of lithium nickel cobalt manganate (Li (NiCoMn) O2, NCM) or lithium nickel cobalt aluminate. (NCA) Lithium batteries with ternary cathode materials use nickel salt, cobalt salt, and manganese salt as three different component ratios and adjust them differently, so they are called "ternary" and include many types of batteries with different ratios. Distinguished by shape, they can be divided into soft-pack batteries, cylindrical batteries and square hard-shell batteries. Its nominal voltage can reach 3.6-3.8V, with relatively high energy density, high voltage platform, high tap density, long cruising range, large output power, poor high temperature stability, but excellent low temperature performance and relatively high cost.
Battery industry experts believe that blade batteries have five major advantages
1. According to the raw material standard system, the conceptual energy density can reach 350 watt-hours per kilogram, so the development potential is huge compared to lithium iron phosphate. is important.
2. The volumetric energy density has been significantly improved. Through the patented "Blade Battery" technology, the PACK volumetric energy density can exceed 330 watts per hour/L, which can be improved by 30 or more compared to the inherent battery system.
3. The cost is significantly reduced by thirty or more. By rationally saving raw materials, labor service costs, etc., the cost of battery packs is expected to be significantly reduced by 30%.
4. Good heat dissipation performance. Since the "blade battery" is thinner than the traditional prismatic battery, the heat dissipation effect is stronger.
5. It has high safety, single battery array combination, very safe and reliable. The difference between blade batteries and ternary lithium batteries is very obvious. The biggest advantage of lithium iron phosphate is safety, stability and cycle. The shortcomings of long service life are poor low-temperature performance and relatively low energy density. Ternary lithium batteries can achieve relatively high energy density, but have poor high-temperature performance and are slightly less safe and stable than lithium iron phosphate. inferior. If the "blade battery" launched by BYD can really effectively solve the energy density problem and the price is very competitive, it will still have great market potential.
