How is a pouch battery made?

Pouch batteries, also known as flexible batteries, are a type of lithium-ion battery that uses aluminum-plastic film as the packaging material. Unlike metal shell cells, which can be made of steel or aluminum and come in cylinder or square shapes, pouch cells offer a range of advantages, including superior safety performance, lightweight design, small internal resistance, long cycle life, flexible shape and design options, and more.

One of the key advantages of pouch batteries is their safety performance. Because they use aluminum plastic film in their structure, pouch batteries are less likely to explode in the event of a security problem. Instead, the battery will generally blow open, which is a much safer outcome than an explosion. This is in contrast to metal shell cells, which can be more dangerous in certain situations.

Another advantage of pouch batteries is their lightweight design. The weight of a pouch battery is typically 40% lighter than a steel shell lithium battery of the same capacity and 20% lighter than an aluminum shell lithium battery. This makes them an excellent choice for applications where weight is a critical factor, such as in portable electronic devices.

Pouch batteries also have a smaller internal resistance than other types of lithium-ion batteries, which can greatly reduce self-discharge. This means that the battery will retain its charge for longer periods of time, which is important in applications where the battery may not be used for extended periods.

In addition to their long cycle life, which is typically 100 times or more, pouch batteries offer flexible design options. Their shape can be variable and customized according to customer needs, which is important for applications where space is limited or unconventional shapes are required.

One of the primary applications of pouch batteries is in the power battery field. With the introduction of new subsidy policies for new energy vehicles, the system energy density of batteries has become an important assessment index. The capacity of ternary pouch battery is typically 10-15% higher than the steel shell battery of the same size specification, and 5-10% higher than the aluminum shell battery. Additionally, the weight of a ternary pouch battery is lighter than that of a steel shell or aluminum shell battery of the same capacity specification. As a result, the subsidy new policy is more favorable for ternary pouch batteries.

Industry experts expect that as battery technology continues to develop, the penetration rate of pouch batteries in the new energy vehicle market will continue to improve. The proportion of pouch batteries in various types of batteries is expected to exceed 50% in the future.

The pack method of pouch battery is also unique. The material used in the shell determines the way they are packaged. Only pouch batteries have aluminum plastic film, which requires thermal packaging to combine the three layers of material evenly and firmly together. The aluminum plastic film generally has three layers, including a nylon layer to ensure the appearance of the film and reduce damage to the shell, an Al layer to prevent water infiltration and maintain the internal environment of the cell, and a polypropylene (PP) layer for thermal packaging. The PP layer melts at temperatures of more than 100 ℃ and has viscosity, which allows it to bond together under the action of head heating. Once the head is removed, the cooling solidifies the bonding. PP will not be dissolved or swollen by the organic solvent in the cell, which effectively prevents the internal electrolyte from contacting the Al layer and avoids corrosion.

Overall, pouch batteries offer a range of advantages over other types of lithium-ion batteries. They are safer, lighter, and have a smaller internal resistance, longer cycle life, and flexible design options. They are particularly well-suited for applications where weight is a critical factor, and their use in the new energy vehicle market is expected to continue to grow in the coming years.
