Panasonic Corporation announced that it has developed a Pin Shaped Lithium Ion Battery (CG-320, nominal capacity 13mAh) with a diameter of 3.5mm and a weight of 0.6g suitable for powering small devices such as wearable devices. This product, on top of being the industry’s smallest*1 cylindrical shaped rechargeable Lithium Ion battery, features the high reliability and high output required for near-field communications (NFC). Mass production and shipping are planned to begin in February 2015 with a monthly production of one hundred thousand units.
The full-scale introduction of wearable device products, anticipated widely as the next wave in mobile devices after smartphones, is expected in a wide variety of applications from 2014. Rechargeable batteries, the power source for wearable devices, are expected to be not only small and light, but also to have a high level of reliability and performance.
Panasonic has taken advantage of its battery material technology cultivated with lithium ion batteries used in information and communication equipment applications, and coin-shaped and other small lithium battery production technology, to commercialize this battery, which at 3.5mm is the industry’s smallest pin-shaped lithium ion battery. This product is a rechargeable battery that can be used repeatedly and has the output capability required for NFC. A stainless steel can is used for the exterior providing for dimensional stability. It will be possible to ensure good design for slim devices such as pen-shaped or spectacles-shaped products.
Panasonic will apply the know-how and technology cultivated from many years of material and production technology development to further expand the line-up of this new product, which is an innovation in battery technology.
This product was displayed at CEATEC JAPAN 2014 from October 7th to the 11th at Makuhari Messe
