SECONDARY BATTERY AND METHOD FOR ITS MANUFACTURING

The present invention relates to secondary battery which comprises - A negative electrode (anode) having a first metal or a first alloy or a host material capable of reacting with or intercalating a chloride ion as anode material, - A positive electrode (cathode) having a chloride of a second metal or of a second alloy or a chloride intercalation compound as cathode material, - A separator to separate the cathode from the anode, and - An electrolyte which exhibits an chloride ionic conductivity. The present invention further relates to a method for manufacturing such a secondary battery. The present invention refers to a safe and energetic rechargeable battery which is based on the transfer of chloride ions. The main advantage of such a battery is attributed to the fact that chloride ions are environmentally friendly and abundant at the same time.
