Energy density of ternary lithium batteries

source:Industry News release time:2024-01-17 Hits:     Popular:AG11 battery

  

  Energy density refers to the size of energy stored in a certain space or mass of matter. The energy density of a battery is the average amount of electrical energy released per unit area or mass of the battery. Battery energy density=battery capacity × The basic elements of discharge platform/battery thickness/battery width/battery length are Wh/kg (watt hours/kg). The higher the energy density of a battery, the more electricity is stored per unit area.

  High energy density is the biggest advantage of ternary lithium-ion battery packs, so lithium-ion battery packs of the same weight have a higher battery capacity, which allows the car to run farther and at a faster speed. The voltage platform is an important indicator of battery energy density, directly related to the basic efficiency and cost of the battery. The higher the voltage platform, the larger the specific capacity. Therefore, for batteries with the same volume, net weight, or even the same ampere hour, ternary lithium-ion batteries with higher voltage platforms have longer battery life.

  A ternary lithium-ion battery refers to a lithium-ion battery that uses nickel cobalt manganese lithium ternary cathode material as the positive electrode material. Compared to lithium iron phosphate batteries, ternary lithium-ion battery packs have a more average overall performance, higher energy density, and higher volume to energy ratio. With the development plan of the battery industry, the price of ternary lithium-ion batteries has also reached an acceptable range for manufacturers.
