In mobile devices, battery designers used to have two knobs to turn: energy density and cost. Now, mobile device manufacturers are fine tuning all the characteristics of battery and power management, including volumetric density, safety, form factor, thermal tolerance and durability. For instance, wearable device designers are choosing batteries that have moldable form factors and excellent volumetric density over gravimetric density.
Just in the meantime of the develop of various wearable devices around the world, a wide range of Lithium Polymer battery cells with quite special technology have been designed, and manufactured in mass, to meet the increasing needs of the wireless electric devices,such as smart watches, smart bracelets, fitness trackers, children safety devices, pet trackers,and so on.
