Energy density of lithium ternary batteries

What is lithium ternary battery?

Lithium Ternary Battery This is a type of lithium-ion battery, which consists of battery cathode material, anode material and electrolyte. Lithium-ion batteries have the advantages of high energy density, high voltage, low cost and safety, therefore, lithium-ion batteries have become one of the most advanced renewable energy storage technologies. At this stage, lithium-ion batteries are widely used in cell phones, notebook computers, digital cameras and other portable electronic products.

Characteristics of ternary lithium battery

1. Small size:

Ternary lithium batteries are small in size and large in capacity, so they can hold more and more power in a limited space and have a much larger capacity than ordinary lithium batteries.

2. High durability:

Li-ion ternary batteries are highly durable, able to support a long time of use, not easy to break, and are not affected by any ambient temperature.

3. Environmental protection:

Ternary lithium batteries do not contain mercury, do not cause pollution to the environment, and can be recycled, which is a green, environmentally friendly energy.

Energy density of lithium ternary batteries

Energy density is the size of the energy reserve in a given space or mass of material. The energy density of a battery is also the amount of electrical energy released per unit area or mass of the battery on average. Battery energy density = battery capacity x discharge platform/battery thickness/battery width/battery length, with the basic element Wh/kg (watt-hours per kilogram). The greater the energy density of a battery, the more power is stored per unit area.

High energy density is the biggest advantage of ternary lithium-ion battery packs, so the same weight of lithium-ion battery packs with higher battery capacity, the car will run farther distance, speed can be faster. The voltage platform is an important indicator of battery energy density, directly related to the basic effectiveness of the battery and expenditure, the higher the voltage platform, the greater the specific capacity, so the same volume, net weight, and even the same ampere-hour battery, the voltage platform is higher ternary material lithium-ion batteries have a longer range.

Ternary lithium-ion batteries are lithium-ion batteries that use lithium nickel manganese cobalt manganate ternary cathode material for the battery cathode material. Compared to lithium iron phosphate battery, ternary lithium-ion battery pack has a more average overall performance, higher energy density, volume specific energy is also higher, and with the battery industry development plan, the price of ternary lithium-ion batteries has come to a range that manufacturers can accept.
