Earlier today, we did hear about how the folks over at LG are working on a new kind of hexagonal battery technology for smartwatches, and this time around, we have received word that Samsung, too, are interested in churning out new batteries for mobile devices. The whole point of these new batteries would be to deliver a far more improved battery life – so much so that Samsung has ambitiously targeted double the amount of today’s capacity, as they want to ensure this dream comes to fruition through the use of new materials as well as new technologies. Samsung mentioned, “By doubling battery capacity, most phones will eventually end up with units capable of holding over 6,000mAh of charge which should be enough to get even the most intensive of users through a day – even when the battery begins to wear out.”
How will this new battery come into play then? Well, the graphene layers will first need to be anchored onto the silicon surface in order to make room for the volume expansion of silicon through a sliding process between adjacent graphene layers. When it is paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free graphene coating will enable the full cell to achieve volumetric energy densities of 972 and 700 Whl-1 at first and 200th cycle, respectively, which happen to be 1.8 and 1.5 times higher compared to those of current commercial lithium-ion batteries. Good luck to them – us consumers would not really mind how it works, as long as it gets the job done! We do wonder whether it can forewarn users though of an impending explosion or meltdown.
