Lithium ternary prismatic batteries

Lithium ternary prismatic batteries are lithium-ion batteries that use lithium ternary material as the cathode active material, and are encapsulated in the form of a prismatic shape, which is commonly known as a square battery. This type of battery combines the high energy density of Li-ion ternary material with the space utilisation advantages of prismatic battery structure, and is suitable for a variety of demanding applications, such as electric vehicles, energy storage systems and high-end electronic devices.

 1.Ternary lithium materials

Lithium ternary materials are anode materials composed of three elements such as nickel (Ni), cobalt (Co), manganese (Mn) or aluminium (Al), and common combinations include nickel-cobalt-manganese (NCM) and nickel-cobalt-aluminium (NCA). Lithium ternary materials are widely used because of their high energy density, better cycle stability and voltage characteristics.

 2.Prismatic Packaging

Prismatic batteries are packaged in a rectangular or square shape. Compared to cylindrical batteries, prismatic batteries can be more tightly packed, reducing wasted space in the pack and increasing the overall energy density. In addition, the shape of prismatic batteries is conducive to thermal management, facilitating heat dissipation and contributing to the stable operation of the battery under various environmental conditions.

The specificities of a ternary lithium battery

l High energy density: The use of lithium ternary material makes the battery have high energy density, and the prismatic package further optimises the use of space for applications that require high energy storage.

l Thermal management: The shape of the prismatic cell facilitates the design of an efficient thermal management system to ensure temperature control during operation.

l Customisation: Prismatic cells can be customised in size and shape to suit specific application needs, to accommodate different device interior spaces and installation requirements.

l Safety: While lithium ternary materials may pose a safety risk under extreme conditions, the structural design of prismatic batteries can increase safety, such as the use of metal casings to improve mechanical strength.

Application

Ø Electric Vehicles: used as power batteries to provide high energy density and fast charging capability.

Ø Energy Storage Systems: Used in grid storage, home storage and industrial storage to provide stable and reliable power backup.

Ø High-end electronic devices: Provide long-lasting usage time and high power output in laptops, tablets and professional-grade electronic devices.

Development trend

As battery technology advances, the performance of lithium ternary prismatic batteries will continue to improve, including higher energy density, longer cycle life and better safety. At the same time, solid-state battery technology and cobalt-free material development may also lead the way to the next generation of lithium ternary prismatic batteries
