The Untapped Potential and Advantages of Pouch Cells

In the rapidly evolving field of battery technology, pouch cells have emerged as a highly promising contender, especially in the realms of future solid-state batteries and low-altitude economy development. The ultra-high safety and energy density of pouch cells make them a desirable choice in many applications. Let’s explore the untapped potential and advantages of pouch cells.

What Are Pouch Cells?

Pouch cells are a type of lithium-ion battery characterized by high safety, flexible packaging, lightweight, and high energy density. Unlike cylindrical or prismatic cells, pouch cells use laminated foil-like casings, giving them significant adaptability in terms of shape and size. This adaptability opens up a wide range of applications, from consumer electronics to electric vehicles and renewable energy storage systems.

Advantages of Pouch Cells

1. High Safety Performance

Pouch cells use aluminum-plastic film packaging, which generally only swells and cracks when safety issues occur, unlike steel or aluminum shell cells that might explode.

2. High Energy Density

Currently, the average energy density of mass-produced ternary pouch power cells is 240-250Wh/kg, whereas the energy density of the same material system’s ternary prismatic (hard shell) power cells is 210-230Wh/kg.

3. Lightweight

Pouch cells are 40% lighter than steel-cased lithium batteries and 20% lighter than aluminum-cased lithium batteries of the same capacity.

4. Lower Internal Resistance

The lower internal resistance of ternary pouch power cells significantly reduces self-discharge, improves battery rate performance, generates less heat, and extends cycle life.

5. Flexible Design

The shape can be changed to any form, making them thinner and customizable according to customer requirements, facilitating the development of new cell models.

Future Prospects

The future of pouch cells looks bright, with ongoing research and development aimed at further improving their performance, safety, and cost-effectiveness. Advances in materials science, such as the development of solid-state electrolytes, could potentially enhance the energy density and safety of pouch cells even further.
