ultrathin lithium ion batteries
Round format lithium polymer cell.
Up to now lithium polymer batteries have all had rectangular shapes. Now we have developed a technology to make round or even free-form shapped batteries.

1. High operating voltage (3.7V)
2. Energy density is high
3. No memory effect
4. Self-discharge is less than 1% per month
5. Charge/discharge cycle characteristics are excellent
6. Safety characteristics are excellent
7. Processing temperatures for these cells is 100°C for less than 60 seconds, 120°C for less than 20 seconds and 140°C for less than 5 seconds.
8. Custom sizes can be developed with tooling and minimum order quantity costs. Maximum thickness 5mm, maximum diameter 50mm
