L a m i n a t e t y p e ( UM A L )
Rechargeable battery having long cycle life
High rate charge/discharge is available.
New
Advantages
①
High rate charge/discharge
200mohm low ESR and high rate(10C,120mA) 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 5K cycles. It can realize maintenance free design
