A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period. Credit: Dr. Zhuangnan Li (UCL) While at the proof-of-concept stage, this new bendable graphene-based supercapacitor shows enormous potential as a portable power supply in several practical applications […]

A team of engineers demonstrated how they could — by using aqueous electrolytes instead of the typical organic electrolytes — assemble a substantially safer, cost-efficient battery that still performs well. Non-flammable, cost-efficient, and effective battery developed at Rensselaer Polytechnic Institute. As the lithium-ion batteries that power most phones, laptops, and […]

At left, a 3D model by Rice University materials scientists shows a phase boundary as a delithiating lithium iron phosphate cathode undergoes rapid discharge. At right, a cross-section shows the “fingerlike” boundary between iron phosphate (blue) and lithium (red). Rice engineers found that too many intentional defects intended to make […]

Monash University researchers have developed the world’s most efficient lithium-sulfur battery, capable of powering a smartphone for five continuous days. Prototype cells have been developed in Germany. Further testing in cars and solar grids to take place in Australia in 2020. Researchers have a filed patent on the manufacturing process, […]

High-energy-density polymeric cathode for fast-charge sodium- and multivalent-ion batteries. Next-generation batteries will probably see the replacement of lithium ions by more abundant and environmentally benign alkali metal or multivalent ions. A major challenge, however, is the development of stable electrodes that combine high energy densities with fast charge and discharge […]

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have reported a new mechanism to speed up […]

Lithium ion batteries revolutionised the way we use, manufacture and charge our devices. They’re used to power mobile phones, laptops and even electric cars. Shutterstock British-born scientist M. Stanley Whittingham, of Binghamton University, was one of three scientists who won the 2019 Nobel Prize in Chemistry for their work developing […]

A new design for lithium-ion batteries could dramatically reduce charging times. (Credit: buffaloboy/Shutterstock) Forget the 10 hours it can take to charge your Tesla Model X. A new battery, created by researchers at Penn State, can complete a charge in as little as 10 minutes. Described in a report published today in Joule, the […]

Images taken during a test of APL’s latest lithium-ion battery technology exhibit its inflammable and self-extinguishing qualities.
