THREE-TAB LAMINATED COMPOSITE BATTERY

Disclosed is a three-tab laminated composite battery, where the positive electrode plate and the negative electrode plate are alternately stacked, and adjacent plates are separated by the separator; the positive electrode plate comprises a first positive electrode plate and a second positive electrode plate; the first positive electrode plate comprises a first positive electrode current collector and a supercapacitor positive electrode material arranged on both sides; the second positive electrode plate comprises a second positive electrode current collector and a lithium-ion battery positive electrode material arranged on both sides; the first and the second positive electrode plates are connected to a first and a second positive electrode tab respectively and independent of each other; and the negative electrode plate is connected to a negative electrode tab. The composite battery has the advantages of a lithium ion battery and a supercapacitor, and could avoid a self-discharging effect.
