Lithium-ion

Scientists have made a breakthrough that overcomes a technical issue that has held back highly promising lithium-metal battery architecture, which could pave the way for batteries with as much as 10 times the capacity of today's devices.

A technique is allowing researchers to measure endogenous lithium concentrations in the human brain for the very first time. Researchers found natural lithium levels in white matter were lower in suicidal subjects than healthy controls.

An MIT team has developed an electrolyte solution that can accommodate high-capacity lithium-metal battery chemistry, paving the way for electric cars and mobile devices that could last far longer on each charge.

By swapping out conventional materials for experimental ones scientists continue to make exciting advances in the performance of lithium batteries, and a team in Japan has just published research around a particularly promising one.

Owing to its abundance and low cost, lead is an alternative battery material with plenty of appeal, and scientists have just demonstrated how it can form the basis of a new anode that offers far greater storage capacity than graphite.

QuantumScape has announced stunning performance figures for what may be the first commercially viable solid-state lithium-metal battery. It's claimed to add as much as 80% to the range of an electric car, and charge from 0-80% in just 15 minutes.

A new breakthrough could boost the eco-credentials of an environmentally friendly form of lithium battery even further, by restoring it to its original condition once it is spent using just a fraction of the energy of current approaches.

We got it wrong, folks. The Superbattery from Skeleton Technologies is not a hybrid battery/ultracapacitor energy system, it's an entire new type of cell that sits somewhere in between the two. And it will make it into EVs – just not how we expected.

French company Nawa technologies says it's already in production on a new electrode material that can radically boost the performance of existing and future battery types, delivering 3x the energy density, 10x the power, and vastly faster charging.

A new device from engineers at TU Delft overcomes some of the dependability issues of lithium-metal batteries thanks to a new electrolyte that breaks down and forms a key protective layer during charging.

Just because a lithium-ion battery no longer holds a charge doesn't mean it no longer holds any value. It still contains useful metals, which can now be reclaimed via a more eco-friendly technique – the key ingredient is orange peel waste.

Plans are afoot to build a monster battery cell production facility in the UK, but it's not going to another Tesla Gigafactory. Startup Britishvolt expects construction of its 30-GWh GigaPlant to start in Wales next year.
