As wearable devices becomes smaller and smaller as days goes by, the size of the new fangled battery which Panasonic has just launched also comes in a diminutive package.
The electronics titan made known to the public of its lithium battery which resembles like a pin and just measures 20 mm in length and has a diameter of 3.5 mm. It is just 1/20 of the size of the common AAA batteries. This minuscule battery is the smallest on its category as far as the capacity by volume is taken into consideration.
This small yet power-packed battery is dubbed as CG-320 battery which boasts of a nominal capacity of 13 mAh and voltage of 3.75 V. It can also connect Bluetooth and NFC (near-field communication) links with smartphones.
Panasonic is also on the stage of whipping up two more pin-shaped batteries with current rating of 30 mAh and 50 mAh, though these variants are quite bigger and heavier than the CG-320.
A series of endeavors have been made to enhance the materials and the innards of batteries for wearable devices.
The CG-320 can be likened to the common cylindrical lithium-ion batteries with negative and positive electrode sheets enfolding each other beneath the undersized stainless steel tube.
