Research shows NMC cathode voltage fade is reversible

New research from the University of California San Diego has found one of the causes of voltage fade in lithium-rich layered oxides (LRLO).  LRLO is a promising candidate as a cathode material as it can provide 50% more capacity than current alternatives. However, voltage fade reduces the energy capacity of this material over time. UC… Read more »

Hyundai invests in solid-state battery materials specialist Ionic Materials

Hyundai’s venture capital division, Cradle, is investing in Massachusetts-based battery materials developer Ionic Materials. Ionic says its patented solid polymer material enables solid-state batteries that are inherently safe, high in energy density and operational at room temperature. The special properties of Ionic’s polymer electrolyte also support lithium-ion cells with little to no cobalt in their cathodes…. Read more »

Audi Hungaria begins mass production of electric motors for e-tron quattro lanuch

One of Audi’s key manufacturing plants, Audi Hungaria, has officially begun series production of electric motors. Audi’s first all-electric vehicle, the e-tron, will rely heavily on the plant’s electric motor production capacity. The new dedicated 8,500-square-meter floor space uses a modular intelligent-assembly system in order to roll out 400 electric-axle motors per day. Though this number… Read more »

Midtronics sells Stationary Power Division to focus on automotive market

In order to focus on the global transportation market, battery management specialist Midtronics has sold its Stationary Power Division (SPD) to Franklin Electric. The SPD will be combined with Franklin Electric’s Electric Grid Solutions division and will provide the same contact information for product service and support. “The divestiture of the Stationary Power Division enables us… Read more »

Tesla files patent for a system to isolate damaged battery cells

Tesla recently filed a patent on a new technology that could make its battery packs safer. The system is designed to isolate damage caused by failed battery cells, and prevent them from affecting intact cells in the pack. When battery cells fail, they typically release hot gases that can spread the damage to nearby cells…. Read more »

Comparing liquid-dispensed gap fillers and thermal pads in battery packs: WEBINAR

Heat generated in high-density automotive battery packs is often managed by connecting battery cells and/or modules to a heat sink via a thermal interface material (TIM). The TIMs promote heat conduction by displacing any air that resides within the large gaps and microscopic rough surfaces that exist between the substrates to be bridged. In practice, battery… Read more »

Ecovolta to build automated 200 MWh battery assembly plant in Switzerland

Swiss battery system and production specialist ecovolta (don’t kill us yet folks, the lowercase isn’t a typo) will build a 200 MWh battery pack assembly plant this September in the Swiss canton of Schwyz. The plant will use fully-automated processes to produce both prismatic and cylindrical batteries. The battery packs will have voltage levels ranging… Read more »
