CATL launched Freevoy Super Hybrid Battery, the first hybrid vehicle battery to achieve a pure electric range of more than 400 kilometers and 4C superfast charging, heralding a new era for high-capacity EREV and PHEV batteries. With EREVs (extended range electric vehicles) and PHEVs (plug-in hybrid electric vehicles) gaining prominence... Read more →

Argonne scientists have advanced sodium-ion batteries by preventing cracks in the cathode particles during the synthesis process, making them a cost-effective and sustainable alternative to lithium-ion batteries. This research first appeared in Nature Nanotechnology. Artistic rendering illustrating the key finding that lowering the heat-up rate during cathode preparation for sodium-ion... Read more →

A team from Chung Yuan Christian University in Taiwan has fabricated a novel Fe3V3O8 (FVO) anode material for Na/Li-ion storage using hydrothermal technology for the first time. The electrochemical results indicated that the initial sodiation capacity of the FVO anode is as high as 805 mA h g−1 at 100... Read more →

Altris, a Swedish developer and prototype manufacturer of sodium-ion batteries, and Stora Enso, a provider of renewable products in packaging, biomaterials and wooden construction, are partnering to drive the adaptation of Stora Enso’s hard carbon solution Lignode (earlier post) as an anode material in Altris’ sodium-ion battery cells. Altris’ sodium-ion... Read more →

Clarios and Altris, a Swedish developer and prototype manufacturer of sodium-ion batteries, announced an exclusive Joint Development Agreement (JDA) for low-voltage mobility applications. Under the new JDA, Altris will focus on developing the sodium-ion cell technology for low-voltage applications, while Clarios will leverage its expertise in Battery Management Systems (BMS),...
