even after repeatedly being bent to a radius of nearly an inch or twisted to an angle of 25 degrees, Panasonic said. The company plans to start sample shipments of the battery by the end of October, it said. “Product development will continue towards mass production, with an eye to an even slimmer form factor ideal for various IoT devices such as card devices and wearable devices.” Repeated bending and twisting of conventional lithium-ion cells “can cause a big impact on the charge and discharge cycle and life of a battery,” it said. The new battery has been shown to have 80 percent “initial capacity retention” despite 1,000 charge and discharge cycles, and 1,000 bending or twisting repetitions, it said. CEATEC Japan opens Tuesday at the Makuhari Messe convention center for a four-day run.
