Researchers find environment friendly way to develop batteries

Washington: Researchers have developed a new concept for an aluminium battery, which will give it twice the energy density as compared to previous versions, and with least environmental impact.
The idea has the potential for large scale applications, including storage of solar and wind energy. Researchers from Chalmers University of Technology, Sweden, and the National Institute of Chemistry, Slovenia, are behind the idea.
Using aluminium battery technology could offer several advantages, including a high theoretical energy density, and the fact that there already exists an established industry for its manufacturing and recycling.
Compared with today’s lithium-ion batteries, the researchers’ new concept could result in markedly lower production costs, reported the study published in the journal, ‘Energy Storage Materials’.
“The material costs and environmental impacts that we envisage from our new concept are much lower than what we see today, making them feasible for large scale usages, such as solar cell parks, or storage of wind energy, for example,” said Patrik Johansson, Professor at the Department of Physics at Chalmers.
“Additionally, our new battery concept has twice the energy density compared with the aluminium batteries that are ‘state of the art’ today,” added Johansson.
