Features and Benefits
- High Energy Density
~500Wh/l and 400Wh/Kg vs. 300Wh/l and 260Wh/Kg in typical coin cells — enables smaller, lighter devices. - Excellent Storage Life
Retains >98% capacity after 1 year at room temp; no passivation issues. - Stable Voltage Output
Operates between 3.3V–1.5V — ideal for low-voltage electronics. - Ultra-Slim Profile
As thin as 1.1mm; perfect for compact devices like ID tags and smart cards. No swelling during use/storage.
- High Rate Capability
Low-resistance design supports high bursts of energy — great for RF transmitters. - Wide Temperature Range
Operates from -20°C to +60°C — functions even when other batteries freeze. - Standard & Custom Sizes
Custom cell sizes can be designed to fit within the following dimensions:- Length: 20–305mm
- Width: 20mm-205mm
- Thickness: 1.1mm-6mm
Certified, Safe & Ready to Ship
All Thin Cells® are certified to UL 1642 and UN 38.3, with select models meeting IEC 60086-4. They perform in temperatures from -20°C to +60°C and won’t swell during use or storage.
Available in multiple sizes or fully customizable for your application needs.
