Secondary Batteries (Rechargeable Batteries): Lithium Ion Pin-type Battery

Lithium Ion Pin-type Battery design engineers Panasonic
A 3.6mm diameter pin-shaped lithium ion battery which expands design options for micro devices.

The industry's smallest-diameter cylindrical rechargeable battery has been developed using extremely fine components and materials compared to standard Lithium-Ion batteries. Its outstanding technical design makes this battery ideal for wearable devices with heavy power demands. Panasonic intends to expand this new battery line-up successively to meet the requirements of next-generation mobile communication devices.
