    • The present invention relates to a novel process for preparing a lithium polymer secondary battery which comprises a step of direct coating of a plasticized and crosslinked polymer electrolyte onto a lithium electrode. The process for preparing a lithium polymer secondary battery comprises the steps of: (i) dissolving a mixture of a crosslinking agent and a monomer in a molar ratio of 1:1 to 1:11 in a liquid electrolyte of 100 to 400% (w/w) to obtain a polymer electrolyte; (ii) applying the polymer electrolyte onto one side of a lithium electrode and treating with heat or UV to obtain a polymer-coated electrode; and, (iii) bonding the polymer-coated electrode to a positive electrode. In accordance with the present invention, a lithium polymer secondary battery with an improved interfacial stability between a lithium electrode and a polymer electrolyte can be prepared in a simple manner, which makes possible its wide application in the development of lithium polymer secondary battery.
    • 本发明涉及一种制备锂聚合物二次电池的新方法,其包括将塑化和交联的聚合物电解质直接涂覆在锂电极上的步骤。 制备锂聚合物二次电池的方法包括以下步骤:(i)将溶液的摩尔比为1:1至1:11的交联剂和单体的混合物在100至400%(w / w),得到聚合物电解质; (ii)将聚合物电解质施加到锂电极的一侧上,用热或UV进行处理以获得聚合物涂覆的电极; 和(iii)将聚合物涂覆的电极粘合到正极上。 根据本发明,可以以简单的方式制备具有改善锂电极和聚合物电解质之间的界面稳定性的锂聚合物二次电池,这使得其可广泛应用于锂聚合物二次电池的开发中。
