Create Best Curved Polymer Battery Cell For Wearables Prototype – LIPOL

Curved Polymer Battery is the critical developed battery for us, designed for the wearable prototype. A curved polymer battery can make the most of internal space but also keep high volume capacity, extend cycle life, good durability, and reliability. It makes the wearable device looks more lightweight, portable, and comfortable.

Just Like Prismatic polymer battery, we prefer to manufacture some popular curved polymer battery samples for prototyping and evaluation. It can delivered in 5-7days, and help you lock the Mechanical Design in a shorter time. What’s more, PCM (protective board), NTC (Thermistor), and connectors(Molex, JST, Horse) are optional, only included when requested.

We also provide custom special shape polymer batteries for your mechanical design.


1. Curved compact shape

2. High operating voltage (3.7V average, 4.2 volts peak)

3. High density energy but lightweigh

4. Safe with Japan IC+Mos, overdischarge/ overcharge detection

5. Durability and reliability, keep 75%~80%capacity after 500 life cycles

6. Extended polymer battery life, lower self-discharge(only 3%-5% per month)

7. Custom dimensions, capacity for your special wearable design.
