Samsung is working on lithium-ion batteries with graphene balls, which allows to increase the charge capacity, durability and charging speed of the batteries.

We have seen this year how batteries have started to be a very important problem for smartphones. We have seen how the iPhone batteries exploded or warped, something like what happened last year with the Samsung terminal, which 'exploded' due to faulty batteries. The future is in solid batteries, but these will not arrive until 2019. Although solid state batteries aim to take over the market, Samsung continues to research and develop new solutions for batteries, in this case, they would be working on a battery of solid state based on graphene.

Samsung Advanced Institute of Technology, a division of the company, has managed to develop graphene balls, which if implemented in lithium-ion batteries, increase durability and charge them, too. This is a very important solution in a market that is looking for the transition from problematic and unstable lithium to a solid quality solution that guarantees optimal capacity, correct durability and with them, avoid all the problems that are hitting on lithium-ion batteries lately.

Thanks to graphene, the capacity can be increased up to 45% and not only this, it has been possible to increase the charging speed of the batteries by five times, which is to solve other problems of lithium batteries, which are slow loading. The dimensions of the batteries do not change, so we would be facing 4.500mAh batteries that charge in just under a quarter of an hour. Graphene also provides batteries with more stability and resistance.

These new batteries could solve another of the problems of lithium batteries, which is that they heat up, these batteries with graphene, would not exceed 60ºC. Something also very interesting is that these batteries achieve a charge capacity after 500 complete charge and discharge cycles of 78.6%. The technology has been patented by Samsung and its commercial version could take a long time to arrive, but what matters is that graphene is used for a tear and a tear.
