This invention relates to a rechargeable lithium-ion micro battery and associated method of manufacture. The rechargeable micro battery is a cylindrical shape and has a wound jellyroll comprised of an anode electrode sheet, a separator sheet and a cathode electrode sheet. The anode electrode sheet is a mixture of active material (graphite, Si), conductive carbon and binder coated on a copper current collector. A piece of Li metal film is also attached on the copper current collector close to but not contact with graphite mixture. The Li metal film acts as lithium source in the battery and will travel to graphite automatically after injecting the electrolyte into the battery. The loading of Li metal is designed to get the whole anode fully lithiated. The cathode electrode sheet is a mixture of active material (lithium free cathode, like S, MnO2 or delithiated LiCoO2, LiNiMnCoO2, Li2Mn2O4), conductive carbon and binder coated on aluminum current collector. The Li metal attached anode electrode sheet, separator sheet, and lithium free cathode electrode sheet are then wound to a cylindrical shape jellyroll. The jellyroll is sealed in a cylindrical can (Al, stainless steel or Ti) with electrolyte filled in it. With the design anode and cathode, the height of the rechargeable micro battery can be downsized to 1.6 mm with a diameter of 1.8 mm while 4 mm of height is a limit for current winding technology in lithium-ion battery.
