Efficient and mild: Recycling of used lithium-ion batteries

Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles—and increasingly also vehicles—with power. As the share of volatile renewable energy needing electricity storage increases, more and more ...

The role of energy density for grid-scale batteries

Because the sun does not shine at night but all our screens do, we need energy storage to shift solar energy production during the day to when it is needed in the evening. To cope with this intermittence of renewables, we ...

Team develops a novel, completely solid, rechargeable air battery

Metals are typically used as active materials for negative electrodes in batteries. Recently, redox-active organic molecules, such as quinone- and amine-based molecules, have been used as negative electrodes in rechargeable ...

An atomic look at lithium-rich batteries

Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium ion, many challenges still exist—like achieving ...
