Prismatic Cell
A Prismatic Cell is a type of rechargeable battery design that's shaped like a rectangular box or prism (hence the name). It's commonly used in electric vehicles, consumer electronics, and energy storage systems. Unlike traditional cylindrical batteries, prismatic cells are more space-efficient and can be packed together more tightly. Think of them as book-shaped batteries that can be stacked neatly together. They're part of the broader lithium-ion battery family, which includes other formats like cylindrical and pouch cells. When you see this term in job descriptions, it usually relates to roles involving battery manufacturing, design, or quality control.
