The present invention describes a rechargeable electrochemical lithium-ion cell for energy storage that combines active materials (anode, cathode, electrolyte) in a way that it can operate with high energy density (>200 Wh/kg) and high performance during charging and discharging at a wide temperature range and more specifically at temperatures lower than -20°C and at least as low as -40°C. The present invention facilitates the development of systems and devices requiring high energy density storage systems and thus low weight and operation at low temperature conditions with low energy consumption. The present invention can be applied to Space Technology, military applications as well as in the automotive industry where the interest is focused in low weight batteries being capable to operate efficiently at low temperatures. |
