Meta Materials to buy assets and IP of Optodot’s battery separator and coating tech

Materials and surfaces developer Meta Materials has signed an agreement to acquire all the assets and intellectual property of Optodot, a nano-composite battery separator and coating technology company. The acquisition, valued at $48.5 million, includes 67 patents and 22 pending patents. One of Optodot’s patents is for its third-generation NPORE ECS (electrode-coated separator) technology. “Optodot… Read more »

Researchers develop new method for making thin and oxide-based solid-state electrolytes

A team of researchers from MIT and Samsung have invented a new approach for manufacturing oxide-based and thin solid-state electrolytes that doesn’t require sintering. In an article published in Energy & Environmental Science, the researchers write: “We report a ceramic manufacturing method termed sequential decomposition synthesis (SDS), which results in ceramic films with thicknesses between… Read more »

CATL to supply batteries for Solaris electric buses in Europe

Chinese battery supplier CATL has announced that it will provide lithium iron phosphate batteries for Solaris Bus & Coach electric buses produced for the European market.

Brookhaven researchers describe benefits of electrolyte additive

A team led by researchers at DOE’s Brookhaven National Laboratory has investigated the benefits of a lithium difluorophosphate additive for electrolytes in lithium batteries with nickel-rich layered cathodes. According to Brookhaven, the possibility of high-energy-density cells composed of nickel-rich layered cathodes and lithium metal anodes is limited by processes that reduce their capacity. In an… Read more »
