Samsung Electro-Mechanics is currently testing a new all-solid-state battery for wearable devices. Unlike the currently employed lithium-ion batteries, no liquid electrolytes are necessary with a solid-state battery which is, in fact, solid. The energy density of the solid-state battery, at 200Wh/L, not only tops the density of lithium-ion batteries, it also has the highest density in the industry. Samsung’s Electro-Mechanics unit has been working for three years on the solid-state battery and created a prototype that customers are currently testing.
Another advantage to solid-stater batteries is that they can be manufactured in different shapes which helps when you plan on using the batteries on small wearable devices. Samsung seeks to protect its lead over other tech companies in this segment of the battery market as it has filed over 40 patent applications related to oxide-based all-solid-state batteries.

Manufacturers have been looking for a way to replace lithium-ion batteries and Samsung seems to have a replacement just a couple of years away. The solid-state battery can be produced in sizes ranging from millimeters to centimeters depending on the needs of each customer. Samsung says that to produce these batteries, it would use its multi-layer ceramic capacitors production technology which alternately prints thin layers of material and then stacks them.
