Provided is a lithium polymer battery having a solar cell, which is capable of self charging without using a separate battery charger when a discharged lithium polymer battery is charged. The lithium polymer battery(20) having a solar cell(10) comprises: a pouch adhesion part which is formed on the back glass of the solar cell(10) and has a gap for vacuum; a lower foil formed within the pouch adhesion part; an insulating coating layer formed on the lower foil; a lithium polymer battery(20) which is formed on the insulating coating layer of the lower foil and is obtained by stacking a plurality of negative electrodes, separators, and positive electrodes; a pouch which has an edge member to be glued to the pouch adhesion part and covers the lithium polymer battery; and a protection circuit module(40) which has a circuit for protecting the lithium polymer battery(20). The lithium polymer battery(20) having a solar cell(10) is prepared by gluing the edge member of the pouch to the pouch adhesion part, making a space between the pouch and the lower foil into a vacuum state by the gap for vacuum, and performing pressing and sealing. |
