Maxwell claims that its dry electrode tech enables an energy density of over 300 Wh/kg in current demonstration cells and they see a path to over 500 Wh/kg.
That’s believed to be about 15 to 100 percent better than Tesla’s current technology.
They also demonstrate close to 90% capacity retention after almost 1,500 cycles and their cells maintain their capacity at higher discharge rates and much better than the same cells without their dry electrode.
