Why Does Winston Battery Use a Prismatic Plastic Shell Cell Design?

Winston Battery uses prismatic plastic-shell cells based on long-term safety and structural stability considerations. Plastic enclosures are electrically insulating, chemically inert, and corrosion-resistant, making them well suited for humid, saline, or harsh environments. The prismatic form factor enables more uniform heat distribution and better control of mechanical stress. In abnormal conditions, plastic shells also reduce the risk of conductive short circuits or heat transfer through the enclosure. This design choice prioritizes safety and predictable behavior over aesthetics or minimal weight.
