Lithium-ion batteries power smartphones, laptops, electric vehicles and many other devices. However, their ability to hold energy slowly declines with repeated charging and discharging. Scientists have now developed an electrolyte additive that could help these batteries last much longer by strengthening a protective layer inside them. The research was led by Professor Noriyoshi Matsumi at […] Th…

Nature Communications, Published online: 08 September 2026; doi:10.1038/s41467-026-77521-0 Ruthenium oxide can lower the demand for scarce iridium in acidic water electrolysis, but its long-term stability is limited. Here, the authors report a two-dimensional carbon-ruthenium oxide composite that stabilizes active sites and enables durable water-splitting performance.

Ontario's OVIN fund is putting up to $696,000 CAD into a $2 million-plus HYGN Energy hydrogen battery pilot at a Rainbow Concrete site in northern Ontario. <p>The post Ontario invests in HYGN Energy’s hydrogen battery storage pilot first appeared on Winssolutions .</p>

China's power battery industry has reported robust growth through the first seven months of 2026, driven by rising demand across both electric vehicles and stationary energy storage applications. According to the latest data from the Ministry of Industry and Information Technology of the People's Republic of China (MIIT), cumulative sales of power batteries reached 790.4 gigawatt-hours (GWh) betw…

A signal that appears to show ions moving inside a battery may, in fact, be an illusion caused by an uneven surface. A KAIST research team has identified the origin of this type of artifacts, which can lead researchers to misinterpret what is happening inside a battery, and has developed a method to reduce it. The findings are expected to enable more accurate analysis of ion movement and improve …

Fraunhofer EMI’s one-of-a-kind system films thermal runaway inside large prismatic cells at up to 1,000 frames per second.

Nature Communications, Published online: 07 September 2026; doi:10.1038/s41467-026-77589-8 Lithium metal batteries face safety and lifespan challenges. Here, authors develop a nanocluster electrolyte that suppresses dendrites, forms stable interphases, and enables >800 cycles in high loading cells and >500 Wh kg-1 in Ah-level pouch cells, with nail penetration and overcharge tolerance.

Researchers at Nagoya University have grown an oxyfluoride crystal with a lithium-ion conductivity of 16.3 millisiemens per centimetre, the highest reported for oxide-related solid electrolytes. A research team at Nagoya University has grown millimetre-sized crystals of a lithium lanthanum niobium oxyfluoride solid electrolyte, known as LLNOF. At room temperature, the material reached a bulk lith…

LANXESS is further expanding its business with materials for lithium iron phosphate (LFP) batteries. The specialty chemicals company has opened a new battery laboratory at its Krefeld-Uerdingen site. There, LANXESS tests and develops battery materials based on iron oxide and iron phosphate. The labo...

A metal surface that becomes more active as it changes could help green hydrogen electrolyzers run harder and longer. Researchers at the Chinese Academy of Sciences have developed an electrode that combines five metals in a high-entropy antiperovskite structure. Supported on porous nickel foam, the material helped an anion exchange membrane (AEM) electrolyzer sustain industrially [...]

Researchers have found an unexpected way to make salt water batteries more powerful: adding a small amount of bleach. The discovery could support the development of safer and less expensive batteries for storing electricity on power grids. Scientists at the US Department of Energy’s Oak Ridge National Laboratory, or ORNL, were initially trying to improve […] The post Bleach Gives Saltwater Batter…
