Ultra-Thin and Compact Energy Storage Solution

EnerCera Pouch

Rapid, Constant-Voltage Charging Now a Reality thanks to an Ultra-Slim Rechargeable Battery that Can be Bent more than 5000 Times*1

EnerCera Pouch

*1 Testing performed in accordance with ISO14443 Part 1: physical properties of smart cards

Issues to be solved

Have you ever faced issues such as

  • There is no compact and thin Lithium-ion rechargeable battery that is powerful enough to drive wireless communication and yet light enough to be unobtrusive in wearable devices.

  • There is no readily mass-producible Lithium-ion rechargeable battery that can be hot-laminated.

  • There is no compact energy storage device which can efficiently store the minuscule currents yielded from energy harvesting and wireless recharging, can supply high power with little voltage drop, and can be used as maintenance-free power sources.

EnerCera Pouch to the rescue!

EnerCera Pouch features

  • EnerCera Pouch is an ultra-thin (0.45mm / 0.018inch), bend-resistant rechargeable Lithium-ion battery that can be embedded into a credit card

  • It is also the first ever Lithium-ion battery able to withstand the hot lamination process used in smart card manufacture

  • EnerCera Pouch can be charged rapidly using contactless card readers
