Lithium-ion (Li-ion) batteries are the most promising technology at the moment for large-scale energy storage. EU-funded researchers achieved battery designs that are more durable and with better features by improving the chemistry of the electrolyte components.
In their bid to reduce carbon dioxide emissions, power companies have turned to renewable energy sources such as wind, wave and solar. However, the power supplied by these sources is intermittent, as it depends on external variables. Making renewable energy practical requires examining new methods of storing energy on a large scale and releasing it on demand.
