NEC develops ultra-thin organic radical battery compatible with IC cards
NEC has developed an ultra-thin, 0.3mm thick, organic radical battery (ORB) that is compatible within standard IC cards of 0.76mm thickness.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.
Conventional ORBs of 0.7mm thickness are difficult for IC cards of standard 0.76mm thickness to adopt. 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.
