Russian Scientists Amp Up Battery Power by Finding Out How to Double Capacity

Researchers from the Siberian Federal University (SFU), the Krasnoyarsk Center at the Siberian Division of the RAS, and the National University of Science and Technology MISIS have discovered a way to make lithium-ion double its capacity. To do so, they came up with the idea to use and vanadium disulfide as an anode. The discovery is described in an article published recently in the Journal of Physical Chemistry.

“The results of our study show that the structures comprised of graphene and vanadium disulfide can be applied as a perspective anode material for lithium-ion batteries with a high unit capacity and charge rate,” the authors wrote in the research article.

The lithium-ion batteries are rechargeable batteries, used today in most electronic devices, including all modern smartphones. This type of has two electrodes: the positively charged anode and negatively charged cathode, separated with a polymer material. When connected to a power outlet, the ions of lithium move from cathode to anode, while the reverse process takes place in the course of giving up the .
