New Electrostatic Nanocapacitors Offer High Power and High Energy Density

Green Car Congress

Batteries, particularly lithium-ion, store large amounts of energy but have more difficulty with high power or fast recharge. Conventional electrochemical supercapacitors store charge in electric double layers or in faradic reactions, permitting larger energy density storage on the electrode surfaces.

Mercedes unveils VISION EQXX electric halo car; range and efficiency

Green Car Congress

Those who paid attention in physics class will know that heat is an energy form in a new guise. The solar energy is stored in a lightweight lithium-iron-phosphate battery, which supplies a climate blower, the lights, the infotainment system and other ancillaries. Overall, the battery weighs around 1,091 lbs, including the OneBox.
