Lithium-ion

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.

Carefully introducing new materials into the design of today’s lithium-ion batteries has the potential to greatly improve their performance, and scientists have just happened upon a promising possibility in carbon nanotubes.

Despite advances in new battery designs, good old lithium-ion batteries are still the frontrunner. There’s plenty of room for improvement though, and now researchers have identified a new cathode coating that could make them safer and longer lasting.

Researchers out of the Chinese University of Hong Kong have used a polymer commonly found in skin cream as a stabilizing agent for an aqueous lithium-ion battery, keeping costs and toxicity low and creating a stable voltage for common usage.

California's Enevate says it's managed not only to achieve an incredibly fast-charging solution for lithium-ion EV batteries, but one that handily boosts energy density as well. Using silicon anodes, it could give you 250 miles of range in 5 minutes.

A new ultrasound device developed at US San Diego offers a solution to a key roadblock when it comes to lithium metal batteries, by using sound waves as a way of preventing dangerous growths that cause them to catch fire and fail.

Described as a “dream material,” lithium metal could give lithium-ion batteries a huge boost but safely integrating it has proven problematic. Scientists have now come up with a new design that avoids these issues and stops it going up in flames.

Lithium-ion batteries degrade over time, but there are ways you can make them last longer. A team at the University of Michigan, Ann Arbor, has put together a list of best practices to preserve the life of lithium-ion batteries as long as possible.

In a quest for safer lithium-ion batteries, a team of engineers at the University of Illinois have come up with a solid polymer-based electrolyte that can not only heal itself but is recyclable without the need for high temperatures or strong acids.

Researchers at Australia's Deakin University say they've managed to use common industrial polymers to create solid electrolytes, opening the door to double-density solid state lithium batteries that won't explode or catch fire if they overheat.

The 2019 Nobel Prize in Chemistry has been awarded to three scientists for the invention and development of the lithium-ion battery.
