The European Battery Business Club (EBBC) is a unique lifelong learning program hosted by Fraunhofer IFAM, which combines battery expertise with years of experience in advanced training.
CATL is working on a more powerful sodium-ion battery:
CATL is developing the second generation of its sodium-ion batteries, which are designed to offer an energy density of 200 Wh/kg. Mid-2021 CATL was one of the first battery manufacturers to present its own sodium-ion battery. The first generation had an energy density of 160 Wh/kg according to the information available at the time. A second generation with 200 Wh/kg has now been announced. By comparison, lithium-ion batteries with liquid electrolyte are maxed out at around 350 Wh/kg.
