NEC Corp has developed an ultra-thin, 0.3mm thick, organic radical battery (ORB) that is compatible within standard IC cards of 0.76mm thickness.

n

The adoption of these ultra-thin ORBs featuring greater flexibility, higher power output and faster recharging speeds than existing rechargeable batteries, including lithium-ion batteries, is expected to enable advanced new functions in IC cards, electronic paper and other technologies.

n

Conventional ORBs of 0.7mm thickness are difficult for IC cards of standard 0.76mm thickness to adopt.

n

These new 0.3mm ORBs are less than half the thickness of existing units, a size reduction that was accomplished by using printing technologies to integrate circuit boards with batteries. As a result, IC cards embedded with these batteries can be used for a wide range of functions, including displays, transmission and advanced encryption processing.
