Panasonic Corporation has developed a pin shaped Lithium Ion battery (CG-320, nominal capacity 13 mAh) with a diameter of 3.5 mm and a weight of 0.6 g. This battery is suitable for powering small devices such as wearable devices. This product, in addition to being the industry's smallest cylindrical shaped rechargeable Lithium Ion battery, features 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 to affect a wide variety of applications beginning in 2014. Rechargeable batteries, the power source for wearable devices, will be small and light as well as feature a high level of reliability and performance.
Panasonic has utilized its battery material technology such as lithium ion batteries, coin-shaped and other small lithium battery production technology, to produce this battery. An exterior stainless steel can provides dimensional stability. This design is suitable for slim devices such as pen-shaped or spectacle shaped products.
