UMAL361421B024TA01

## **Small Energy Device** New **Laminate type (UMAL)** ~~sere~~ **Rechargeable battery having long cycle life High rate charge/discharge is available.** 

## **Advantages** 

## ① **High rate charge/discharge** 

100mohm low ESR and high rate(10C,240mA) enabled by optimizing materials and structure 

## ② **High safety** 

No thermal runaway occurs because of its low capacity and chemically stable materials. 

## ③ **Long cycle life** 

Charge (capacity) recovery is over 90% even after 5000 cycles. It can realize maintenance free design 

## **Applications & Benefits** 

## **1. Energy Harvesting Systems** 

## **2. Backup** 

- ・ Charge/Discharge in Wide Input/Output Range 

   - ・ Can backup system during replacing main battery 

- ・ Long working time due to Low Leakage Current 

- ・ Long backup time over 30sec
