The Panasonic Flexible Lithium-ion Battery is a new type of lithium-ion battery. It is smaller than a credit card and can be repeatedly bent or twisted 1,000 times and still maintain 80% its capacity. Panasonic presented three versions of the new battery at CES 2017.
Yoriko Yagi, assistant chief of planning in Panasonic’s wearable energy department, said that the battery is now ready for mass production, which she expects will begin sometime between April 2018 and March 2019. “Our small devices are increasing, like wearables and IoT devices, and the product design depends on battery size,” Yagi said. “If we want small devices, we need small batteries.”
