Many research centers are developing new solutions for long-term storage of energy, and to improve the existing batteries.
A method to improve the performance of lithium-ion batteries found researchers lab Lawrence Livermore . Scientists have used hydrogen and lower temperatures to change the structure of the graphene electrode, because of which they form defects - pinholes, through which lithium ions can penetrate. As a result, the battery can be charged faster and store more energy.
Researchers estimate that will allow them to improve lithium-ion battery is charged to 40% faster. In the case of energy intensity gains can be from 10% to 40%, but the pre-scholars need to resolve a number of issues.
