Samsung show off tech that doubles lithium-ion battery life

29 June 2015

lemmon_battery_ Battery life is one of the main bugbears of anyone who has a mobile. Well, researchers at Samsung reckon they've found the new technology that will enable batteries to offer up to 1.5 and 1.8 times higher capacity than those doing the rounds now.

How? Well, they've come up with a brand new way of coating the battery cathodes, which means they can get more juice for your device.

The report explains to those people who understand this sort of thing: "Here we report direct graphene growth over silicon nanoparticles without silicon carbide formation. The graphene layers anchored onto the silicon surface accommodate the volume expansion of silicon via a sliding process between adjacent graphene layers. When paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free graphene coating allows the full cell to reach volumetric energy densities of 972 and 700 Wh l-1 at first and 200th cycle, respectively, 1.8 and 1.5 times higher than those of current commercial lithium-ion batteries."

We fell asleep about half way through the second sentence of that. However, BATTERIES THAT LAST LONGER! WE'RE INTO THAT!

The best thing about this, is that Samsung think this is commercially viable, which means this isn't one of those developments that stay in the lab, which means this should end up in the phones they release in the future.

When will we see this fancy new batteries? Well, Samsung are working things out, trying to improve the effectiveness of the battery.
