Birnessite What Is And What It Could Mean For Batteries

August 3, 2021 | Leave a Comment

North Carolina State University scientists are researching birnessite. Birnessite is a hydrated layered form of manganese oxide that can quickly store and release a variety of positive ions from electrolytes for many cycles. This makes it promising for use in high-power electrochemical energy storage, or in emerging electrochemical technologies such as desalination and rare element […]

Lithium Air Battery Progress Makes Electrolyte Improvement

June 17, 2021 | 1 Comment

Research led by the University of Liverpool, in partnership with Johnson Matthey PLC and Loughborough University has made significant progress in the development of stable and practical electrolytes for lithium-oxygen batteries. The lithium-oxygen (Li-O2) battery (or lithium-air battery), consisting of Li-metal and a porous conductive framework as its electrode’s, releases energy from the reaction of […]

New Electrolyte Idea Offers Better Lithium Ion Batteries

April 21, 2021 | Leave a Comment

Massachusetts Institute of Technology (MIT) researchers have identified a novel electrolyte that could be useful for next-generation lithium-ion batteries, increasing their power per weight without sacrificing the cycle life. Lithium-ion batteries have made possible the lightweight electronic devices whose portability we now take for granted, as well as the rapid expansion of electric vehicle production. […]

Better Supercapacitors With New Detergents Added

August 29, 2019 | Leave a Comment

An international team of scientists, including a professor of chemistry from the University of Bristol has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of detergents chemically related to laxatives. Their paper, published today in the journal Nature Materials, explained why these detergents, called ionic liquids, are […]

A New Flow Battery Chemistry

March 4, 2015 | 1 Comment

Pacific Northwest National Laboratory (PNNL) is announcing a new zinc-polyiodide redox flow battery that uses an electrolyte that has more than two times the energy density of the next-best flow battery and may exceed lithium-ion. The new zinc-polyiodide redox flow battery is described in the team’s paper published in Nature Communications. The zinc-polyiodide redox energy […]
