专利汇可以提供Lithium solid electrolyte battery专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a lithium solid electrolyte battery which has a small internal resistance and an excellent discharge characteristic by roughening the surface of a formed positive pellet. CONSTITUTION:A formed pellet contains PbI2, MoS2 and TiS2 used as positive active materials, and at least one powder chosen from among plastic metals such as Pb, Cu and Al. The contact interface of the above formed pellet which touches a solid electrolyte is roughened. Such roughening of the formed pellet can be easily performed by packing a given amount of mixture powder consisting of the positive active materials and a plastic metal into a specific cylinder, and then pressure-molding the mixture powder by means of either a press piston which is provided with a sand paper stuck on its press surface, or a press piston having a rough press surfac. The formed pellet prepared in such a manner as above provides a large contact area between the active material and the solid electrolyte. As a result, the internal resistance of the battery is decreased, and the discharge current of the battery is increased.,下面是Lithium solid electrolyte battery专利的具体信息内容。
