NOVELTY - Lithium polymer secondary battery negative electrode and a positive electrode separated by an electrolyte layer. The electrodes have a solid electrolyte layer in which an organic electrolyte liquid is contained in a polymer.The content of vinylene carbonate of precursor solution of the positive electrode side is smaller than the content in the precursor solution of the negative electrode side.    USE - Used as lithium polymer secondary battery.    ADVANTAGE - It is possible to utilize the properties of the positive electrode and the negative electrode to the maximum. The battery has excellent load characteristics, temperature characteristics and cycle characteristics. A battery of a long lifetime is obtained where the properties are not deteriorated on repeated cycling.    DETAILED DESCRIPTION - Lithium polymer secondary battery a negative electrode and a positive electrode separated by an electrolyte layer. The negative electrode and the positive electrode have a solid electrolyte layer in which an organic electrolyte liquid is contained in a polymer. The polymer is obtained by solidifying a precursor solution including vinylene carbonate. The content of vinylene carbonate of the precursor solution of the positive electrode side is smaller than the content of the vinylene carbonate in the precursor solution of the negative electrode side.    An INDEPENDENT CLAIM is also included for the manufacture of the lithium polymer secondary battery by gradually solidifying the precursor solution of the polymer composing the solid electrolyte of the positive electrode side and the negative electrode side, and combining the electrodes via the electrolyte layer.
