Scientists in Australia have come up with a new design for lithium sulfur batteries that involves adding a sugar to address inherent stability issues, a move that keeps the experimental cells ticking across more than 1,000 cycles.

Stanford University scientists experimenting with a decades-old, single-use battery architecture have led the development of a version that is not only rechargeable, but offers around six times the capacity of today's lithium-ion solutions.

Graphene is already shaping the future of battery technology in some interesting ways, and now scientists have deployed a novel form of the wonder material in a sustainable sodium battery to bring about a tenfold increase in capacity.

A team in Germany has just taken an important step forward in energy storage research, demonstrating a lithium-metal battery with a remarkable energy density of 560 Wh/kg and an ability to retain its performance across hundreds of cycles.

Scientists at Oak Ridge National Laboratory have developed a new robotic system that automatically disassembles spent electric vehicle batteries with great efficiency and safety, making them easier to recycle.

Electronics and batteries are vulnerable to very high or low temperatures, but a new thermal switch could help deal with both. Made from graphene foam, it can dynamically trap heat when it’s cold out or allow heat to escape when it gets too warm.

We've seen how "structural batteries" could be applied to electric vehicles and gear for soldiers as a way of saving weight, and now scientists have applied this type of thinking to microbatteries light enough to be carried by insects.

Scientists in Japan have put forward a promising solution to an inherent instability plaguing lithium sulfur batteries, integrating a novel sponge material that enabled a prototype to safely endure hundreds of cycles.

Leveraging salt could help us avoid much of the cost and difficulty in sourcing scarcer lithium, and Chinese giant CATL is looking to lead the charge by launching its first commercial sodium-ion battery.

A team led by the Nobel-Prize-winning inventor of rechargeable lithium batteries has come up with a way to boost their capacity, developing a novel coating that protects against significant losses at the outset.

Scientists at Sandia National Laboratories have come up with a new design that addresses a number of shortcomings with current molten salt batteries, demonstrating one that can be constructed far more cheaply than currently available versions.

German startup Sono Motors has introduced new battery technology for its forthcoming Sion electric vehicle that promises to not only power the vehicle across longer trips but allow higher charging rates in between.
