"Aluminate"solid polyelectrolytes carrying lithium tetra (alkoxy) aluminate complex units or "Thioaluminate"types carrying tetra (alklthio) aluminate complex units were newly developed. These solid polyelectrolytes gave single ionic conductivity on the contrary to the bi-ionic nature of hybrid polyelectrolytes as high as 10^<-6> and 10^<-5>S/cm, respectively. Both polyelectrolytes are thermally stable up to 250ﾟC,and easily disposable becausse of non-toxicity.Among the examination of rechargeable batteries with metakkic lithium anodes, the best results were obtained when TiS_2 or oxidized state polyaniline were used as cathodes. Especially when the extra lithium salts were added to the polyelectrolyte in suitable amount in order to realize the ideal bi-ionic conduction, t_+=t_-=0.5, high capacity of about 20 mAh/g was established without the significant decay of discharging plateau potential. While the aluminate polymer complex polyelectrolytes were stable in contact with metal oxide cathode materials, the corresponding thioaluminate types decomposed due to contaminating moisture. Only sulfide or selenide calcogen materials were available as cathode materials in the case of thioaluminates.During the course to search for non-flameable and safe electrode mataerials, we found anormalous dda graphite (AG) fine powders with strong acceptor properties which will be used in stead of ordinary calcogenides. This AG material may open the possibility to prepare high performance all carbon cells such as [Graphite-Li (anode) /electrolyte/AG]. At the same time, as AG can be used as a cathode material in combination with the highly conductive but unstable thioaluminate polyelectrolytes, it may provide the rechargeable batteries with higher capacity and current density.

新开发的“铝酸”固体聚电解质（含烷氧基）铝制复合物或“硫代铝酸盐”类型的“硫氧化剂”类型的类型载有四（alklthio）铝制复合物。这些固体聚电解质在与分别高至10^<-6>和10^<-5> s/cm的杂交聚电解质的双子性质形成鲜明对比的情况下给出了单离子电导率。两种聚电解质的热稳定最高为250 c，并且由于无毒性而易于处置。在检查使用Metakkic锂阳极可充电电池的检查时，当Tis_2或氧化的态态多苯胺用作阴茎时，获得了最佳效果。尤其是当将多余的锂盐添加到合适量的聚电解质中以实现理想的双离子传导，t _+= t _- = 0.5时，建立了大约20 mAh/g的高容量，而没有明显的排放高原电位的衰减。虽然与金属氧化物阴极材料接触的铝制聚合物复合物聚合物稳定，但由于污染的水分而导致相应的硫氧化氢类型分解。在硫代氧化的情况下，仅作为阴极材料可用硫化物或硒化的钙元材料。在寻找非固定和安全的电极材料的过程中，我们发现具有强受受体特性的非正态DDA石墨（AG）优质粉末，这些粉末具有强大的受体特性，这些粉末将代替普通的骨化剂。该AG材料可能会为所有碳细胞（例如[Graphite-Li（Anode） /Electrolyte /ag]等所有碳细胞准备高性能。同时，由于AG可以与高电导性但不稳定的硫氧化聚电解质一起用作阴极材料，因此它可以提供可充电电池具有更高的容量和电流密度。
