Researchers have developed for the first time a lithium-ion battery that uses a water-salt solution as its electrolyte and reaches the 4.0 volt mark desired for household electronics, such as laptop computers, without the fire and explosive risks associated with some commercially available non-aqueous lithium-ion batteries.

Novel lithium electrodes coated with indium could be the basis for more powerful, longer-lasting, rechargeable batteries. The coating hinders undesirable side-reactions between the electrode and electrolyte, provide a more uniform deposition of lithium when charging, and augments storage in the lithium anode via alloying reactions between lithium and indium. Their success stems from the good diffusion of lithium ions along the interfacial layer.

LiPo batteries (short for Lithium Polymer) are a type of rechargeable battery that has taken the electric RC world by storm, especially for planes, helicopters, and multi-rotor/drone.

Avoid replacing your Roomba's expensive battery and keep it vacuuming longer with these handy tips.

University of Central Florida Assistant Professor Yang Yang's research group has developed two promising energy storage technologies in its work with sustainable energy systems.

A step towards new "beyond lithium" rechargeable batteries with superior performance has been made by researchers at the University of Bath.

The crystal structure for single-crystalline 3Q, a novel organic material developed by Professor Loh Kian Ping and his team at National University of Singapore.

Scanning electron microscope images show an anode of asphalt, graphene nanoribbons and lithium at left and the same material without lithium at right. The material was developed at Rice University and shows promise for high-capacity lithium batteries that charge up to 20 times faster than commercial lithium-ion batteries.

We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of engineers has a different type of lithium sulfur battery that could be more efficient, less expensive and safer.

Motivated by the challenge to drastically reduce the cost of storing renewable energy on the grid while capturing more of it, a group of scientists has developed a battery powered by sulfur, air, water, and salt -- all readily available materials -- that is nearly 100 times less expensive to produce than batteries currently on the market and can store twice as much energy as a lead-acid battery. The inventors present their prototype in Joule.
