High-energy-density polymeric cathode for fast-charge sodium- and multivalent-ion batteries Summary: 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 rates. Scientists now report a high-performance cathode made of
Hope has been restored for the rechargeable lithium metal battery — a potential battery powerhouse relegated for decades to the laboratory by its short life expectancy and occasional fiery demise while its rechargeable sibling, the lithium-ion battery, now rakes in more than $30 billion a year. A new coating could make lightweight lithium metal batteries safe and long lasting, a
Tesla has reportedly signed a battery supply deal with LG Chem for Gigafactory 3 in China. It would be Tesla’s first deal to supply battery cells for its electric vehicles with a company other than Panasonic. At first, CEO Elon Musk said that all of Tesla’s new factories, including Gigafactory 3 in China, will include the production of both battery
Metal-air batteries are one of the lightest and most compact types of batteries available, but they can have a major limitation: When not in use, they degrade quickly, as corrosion eats away at their metal electrodes. Now, MIT researchers have found a way to substantially reduce that corrosion, making it possible for such batteries to have much longer shelf lives.
HYVE, the UK’s largest independent battery manufacturing facility opened in Sunderland. The site is home to Hyperdrive Innovation, a developer and manufacturer of lithium-ion battery technology. Hyperdrive makes battery packs for electric vehicles and energy storage systems and has invested £7m into its manufacturing capabilities since moving to the site in 2014. The new site will allow the company to produce up to
MIT Researchers have devised a new pulsed laser deposition technique to produce thinner lithium electrolytes using less heat. According to the researchers, the use of thinner lithium electrolytes could allow faster charging and might lead to higher-voltage solid-state lithium-ion batteries. Key to the new processing technique for the solid-state battery electrolyte is alternating layers of the active electrolyte lithium garnet component
Finding economical ways to replace the graphite anodes in commercial lithium-ion batteries could lead to lighter batteries that can store more charge. The improved energy density would result from a combination of factors including the lithium-metal anode’s high specific capacity, light weight (low density), and low electrochemical potential. Switching to lithium-metal anodes would greatly extend the range of electric vehicles
Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation’s power grid and longer-lasting batteries in cell phones and laptops.

Deciding how we’re going to invest in clean energy storage requires a similar analysis, say researchers
A team of researchers from Shinshu University in Nagano, Japan is now closer to a thin, high-capacity lithium-ion battery that could open the gates to better energy storage systems for electric vehicles. The research team was led by professor Katsuya Teshima, director of the Center for Energy and Environmental Science (hereinafter called CEES) at Shinshu University in Japan. They published
