Wearable devices are predicted to become the next big thing in the mobile industry, perhaps even taking the lead over smartphones. Since these wearable devices would depend heavily on batteries that can be recharged multiple times, manufacturers see the increasing need to produce rechargeable batteries that are highly reliable and very efficient.
Panasonic's new CG-320 battery is touted as the ideal battery option for wearable devices because of its compact form and light weight. It is designed to fit devices such as hearing aids, fitness bands, glasses and even electronic pens. It also exhibits flexibility and adaptability, which makes it easier for manufacturers of communication devices to accommodate various design options.
The CG-320 battery, which is around one-twentieth the size of a triple A battery, weighs only 0.6g, making it highly suitable for powering small wearable devices. It is currently the industry's smallest lithium ion battery in cylindrical form and features Bluetooth and NFC connectivity options with a 13 mAh nominal capacity and 3.75 voltage quantity.
"The size, which is the smallest of its kind in the industry, can allow more flexible product designs, and the high strength and stability of form deliver high reliability," a spokeswoman for Panasonic said in an email.
The CG-320's 13 mAh capacity may be lower than the 32 mAh capacity of the Jawbone UP24's lithium ion polymer battery. However, this is understandable since its size is also considerably smaller than the latter.
Panasonic plans to develop two additional pin-shaped batteries that will feature capacities of 30 mAh and 50 mAh, which would make them larger and heavier compared to the current CG-320.
Another feature of the new CG-320 battery is its sturdy stainless steel exterior. This type of technology allows the battery to prevent any instances of swelling.
Battery size and power are two of the most important factors considered by makers of wearable devices. The Apple Watch, for instance, needs to be recharged on a daily basis. This frequency in charging may become too big a hassle for such a small device, an issue that Apple needs to find a solution to fast in order to capitalize on the momentum of the market for wearable devices.
Panasonic plans to mass produce the battery and begin shipping by February 2015. A monthly production of 100,000 units is also targeted. The product will be on display at the 2014 CEATEC JAPAN on October 7-11 at Makuhari Messe.
