When designing smartphones, manufacturers always have to make some compromises. Just look at the Samsung Galaxy S6, which albeit being beautifully designed, comes with a skimpy, insufficient battery life.

But with the next-gen Galaxy S7, Samsung might be able to make things better, a lot better, actually. Researchers at Samsung Electronics have announced they have developed a new technology that allows them to produce a silicone cathode material that coats graphene onto a silicon surface in order to allow for higher energy density (as seen at Business Korea).

The layman’s translation to this sentence is that Samsung has managed to identify a way that could almost double the capacity of the lithium batteries that will eventually go on to power future smartphones and tablets.

As you probably know very well, smartphone battery capacity has been slightly increasing in the past few years, but the technology continues to be limited by the physical restrictions of the gadgets and the materials used inside the battery.

Are you ready for a new era in mobile device history?

Early Android devices were bundled with small batteries that offered pretty skimpy battery life due to relatively inefficient internal components and poorly optimized software.

But luckily, advancements in this technology continued to be made. Like Samsung’s new discovery which brings forth a new coating method for battery cathodes. This new technique overcomes the cycling performance and capacity limitations current batteries are faced with.

The process uses graphene, which is grown directly onto the silicon coating surface, without seeing any silicon carbide formation.

Samsung researchers say that the technique will allow the whole cell to reach volumetric energy densities of 972 and 100 Wh l−1 initially and 200th cycle, respectively, when working in concert with a commercial lithium cobalt oxide cathode.

This is 1.8 and 1.5 times greater than the current lithium ion batteries we have on the market today.

Since the batteries boast a multi-layer design, the researchers at Samsung also cite good cycling performance, which should maintain the prolonged life cycle.

Samsung prophesizes that the breakthrough will bring about important implications for both mobile devices and the electric car industry.

So there you have it, folks. Samsung is making great advancements into producing more capable batteries, and hopefully, the next-gen Galaxy S7 will benefit from a typical 2-3 day life cycle.
