Abstract: PURPOSE: A solid polymer electrolyte and method for producing lithium polymer battery are provided for enhancing adhesiveness and mechanical stability of laminate formed by the solid electrolyte without alteration of ionic conductivity by blending PAN and PVdF polymers. CONSTITUTION: The solid polymer electrolyte is produced by mixing PAN and PVdF polymers as the starting materials in a weight ratio of 10:1-1:5, blending it with the organic solvent, SiO2 and the plasticizer; heating the resultant mixture to form solid polymer electrolyte matrix; casting the matrix. The amount of organic solvent added is 1-5 times the amount of the starting materials. The amount of SiO2 is 1-20 wt.% based on the weight of the starting materials. The heating process is carried out at 110-180 deg.C. for 10 minutes to 2 hours. The lithium polymer battery is produced by mixing the solid polymer electrolyte together with the plasticizer to prepare the combined anode and cathode and laminating the electrolyte to form the final product.

Abstract: PURPOSE: A battery having a trench structure and a method for fabricating the battery are provided to improve the quality of the battery by adopting a trench structure into the battery. CONSTITUTION: A battery comprises a substrate(10). The first collector(1) is formed on the substrate(10). A cathode(2) is formed on the first collector(1). An electrolyte(3) is formed on the cathode(2). An anode(4) is formed on the electrolyte(3). The second collector(6) makes contact with the anode(4). One of the first collector(1) and the cathode(2) is etched so as to form a plurality of trenches. The remaining thin film elements are sequentially deposited on the trenches so that the amount of the cathode(2) and the effective contact interface between the cathode(2) and the electrolyte(3) are increased.

Abstract: 본 발명은 카본 전극의 전리튬화 방법과 이를 이용한 리튬 이차전지 제조방법에 관한 것으로, 종래의 리튬 이차전지는 음극으로 사용된 카본 전극이 피막형성 반응의 비가역적 반응으로 리튬 이온의 소모를 가져와 전지의 용량을 감소시키는 역효과와 싸이클 수명이 저하하게 되는 문제점이 있는 바, 본 발명은 카본 전극과 리튬 금속을 저항으로 연결하거나 직접 접촉시킨 상태에서 온도와 전해질의 이온전도도를 변화시켜서 카본 전극이 리튬화 되는 속도와 양을 조절하고, 리튬화 후에 일정 온도와 시간 동안 안정화 시킴으로써 카본 전극 표면상에 안정한 피막을 형성하여 카본 전극의 가역성을 향상시키고, 리튬화된 카본 전극으로 리튬 이차전지를 제조하여, 카본 전극에서의 비가역용량에 의한 용량저하를 방지함으로써 용량증가와 충방전시 충� �전 효율 문제로 인하여 소모되는 리튬의 양을 보충해줌으로써 싸이클 수명을 향상시키도록 한 것이다.
