Graphene aerogel sponge promises battery boost

Researchers in Sweden have used a graphene aerogel to develop lithium sulphur (Li-S) battery that retained 85 per cent capacity after 350 cycles. Developed at the Chalmers University of Technology in Gothenburg, the prototype consists of slices of porous graphene oxide aerogel in a cell battery that soaks up a sulphur-rich ‘catholyte’ solution. This catholyte…

New ‘blue-green’ solution for recycling world’s batteries

Rice scientists show solvent leaches cobalt, lithium for reuse from spent batteries Materials scientists demonstrate an environmentally friendly solution to remove valuable cobalt and lithium metals from spent lithium-ion batteries. The metals and the eutectic solvent they use to extract them can then be recycled. A solution turns green as it pulls cobalt from a…

Energy Aggregation Brings Renewable Energy To More Companies

Power purchase agreements are wonderful for large energy consumers like Google, Facebook, and Apple, which can sign up with a renewable energy developer to take all or a major portion of the electricity produced by a solar or wind farm. But smaller companies are often unable to get the same access to renewables because they…

Modeling and Simulation for Meeting the Challenges of Battery Design

The biggest challenges for battery design are energy density, power density, charging time, life, cost, and sustainability. Modeling and simulation are very efficient methods that can assist researchers, developers, and designers in meeting these challenges. By: Ed Fontes Energy density is limited by the battery’s chemistry, which even without losses limits the theoretical energy density.…
