Recent advances in high energy density batteries have included the development of solid polymer electrolytes to replace conventional liquid or gel electrolytes and the development of organic based redox materials to replace traditional intercalation compounds as the cathode. Problems need to be addressed for the synthesis of these two materials because: (1) Solid polymer electrolytes have a much lower conductivity than conventional liquid or gel electrolytes. The resistance of the polymer film can be reduced by making the film very thin. It is difficult to make ultra-thin polymeric films, though, that are free of pin-holes. (2) The rate capability of solid state lithium batteries can be improved by using organo-sulfur and di-sulfur containing polymers as the cathode material instead of intercalation compounds (such as TiS2), which are presently used in most thin, rechargeable batteries. These new polymeric cathodes also present processing problems because it is difficult to form the required ultra-thin films without defects. The PIs plan to develop plasma polymerization techniques to produce solid polymer electrolytes and polymer redox cathodes for thin, solid-state, rechargeable, alkaline batteries. They will prepare and characterize solid polymeric electrolytes based on plasma polymers of siloxane compounds and polymeric redox materials based on plasma polymerized carbon-sulfur compounds such as carbon disulfide. Substituted phenolic groups will be incorporated into the siloxane plasma polymers (by co-sublimation / plasma polymerization techniques) to prepare the single ion (lithium, sodium or potassium) conducting electrolytes. The relationship between deposition conditions and properties of the materials will be examined. Simple batteries based on these plasma polymerized films will be constructed to test the applicability of these materials.

高能量密度电池的最新进展包括开发固体聚合物电解质以替代常规液体或凝胶电解质，以及开发有机基氧化还原材料以替代传统的插层化合物作为阴极。这两种材料的合成需要解决的问题是：（1）固体聚合物电解质具有比常规液体或凝胶电解质低得多的电导率。聚合物膜的电阻可以通过使膜非常薄来降低。然而，很难制造没有针孔的超薄聚合物膜。(2)固态锂电池的倍率性能可以通过使用含有机硫和二硫的聚合物作为阴极材料而不是目前用于大多数薄的可再充电电池中的插层化合物（例如TiS 2）来改善。这些新的聚合物阴极还存在加工问题，因为难以形成所需的无缺陷的超薄膜。PI计划开发等离子体聚合技术，以生产固体聚合物电解质和聚合物氧化还原阴极，用于薄型固态可充电碱性电池。他们将制备和表征基于硅氧烷化合物的等离子体聚合物的固体聚合物电解质和基于等离子体聚合的碳硫化合物（如二硫化碳）的聚合物氧化还原材料。取代的酚基将被并入硅氧烷等离子体聚合物中（通过共升华/等离子体聚合技术）以制备单离子（锂、钠或钾）导电电解质。将检查沉积条件和材料的性质之间的关系。基于这些等离子体聚合膜的简单电池将被构造以测试这些材料的适用性。
