The most important part of any new Smartphone or tablet is the battery, that powers everything in that device. Batteries capacities (mAh) has increased slightly over the last decade but not as expected. As we can't make batteries any bigger, increases in raw capacity are needed, and researchers have been looking to new materials to find the solution.


This is where Samsung's research comes in. The company has come up with a new coating method for battery cathodes, which overcomes the cycling performance and capacity limitations imposed by current implementations. The new process makes use of that excellent conductive material known as Graphene, which is grown directly onto the silicon coating surface without silicon carbide formation.

Samsung's researchers claim that its technique allows the full cell to reach volumetric energy densities of 972 and 700 Wh l-1 at first and 200th cycle respectively, when paired with a commercial lithium cobalt oxide cathode. This is around 1.8 and 1.5 times greater than commercialized lithium ion batteries, meaning more battery capacity for a given area. Typically, these type of designs reduce the battery's life span due to more charge and discharge cycles, but this time the researchers also claim good cycling performance, due to its multi-layer design.

 

Samsung expects that its breakthrough will have important implications for both mobile devices and the electric car industry, which both really need additional battery capacity. However, like most new ideas, industry observers expect that the technology is at least two or three years away from commercialization.
