This Small Business Innovation Research Phase I project will establish the feasibility of a unique class of hydroxide-conducting, polymer solid electrolyte compositions. These materials are referred to as Hydroxide Exchange Membranes (HEM), which exhibit high OH- conductivity ( 10-2 S/cm) while retaining good film forming properties and mechanical strength. This material would be the first known hydroxide-conducting solid electrolyte. In a preliminary study, Reveo has identified two possible means of synthesizing HEMs. The focus of this study will be on evaluating these HEMs for their hydroxide conductivity, mechanical strength, and film-forming ability, as well as, optimizing the relationships between these parameters.Cost-effective fabrication methods will be identified, and the effect of temperature on performance will be demonstarted. Preliminary results indicate that these HEMs have great potential to fill a tremendous market need in the alkaline battery industry. Since a competing hydroxide-conducting membrane technology does not currently exist, this material will have immediate applications in the alkaline battery industry. It will further have applications and uses in the Reveo zinc-air Fuel Cell Battery and a hybrid class of hydrogen fuel cells. This will remove the need for protection against corrosion or leakage of the liquid electrolyte and increasing the battery energy and power densities. In particular, this material could dramatically reduce alkaline battery material and manufacturing costs while imparting environmentally-safe disposability.Keywords: membrane, hydroxide, fuel cell, battery, solid electrolyte, alkaline, polymerElectrolyte

该小型企业创新研究第一阶段项目将确定一类独特的氢氧化物导电聚合物固体电解质组合物的可行性。 这些材料被称为氢氧化物交换膜（HEM），其表现出高OH-传导率（10- 2S/cm），同时保持良好的成膜性能和机械强度。 这种材料将是第一个已知的氢氧化物传导固体电解质。 在一项初步研究中，Reveo已经确定了两种可能的合成HEMs的方法。 本研究的重点将是评估这些HEMs的氢氧化物导电性，机械强度和成膜能力，以及，优化这些参数之间的关系。成本效益的制造方法将被确定，并将演示温度对性能的影响。 初步结果表明，这些HEMs有很大的潜力，以满足碱性电池行业的巨大市场需求。 由于目前还不存在与之竞争的氢氧化物导电膜技术，这种材料将立即应用于碱性电池工业。 它将进一步在Reveo锌空气燃料电池和混合型氢燃料电池中应用和使用。 这将消除对防止液体电解质的腐蚀或泄漏的保护的需要，并增加电池能量和功率密度。 特别是，这种材料可以大大降低碱性电池材料和制造成本，同时赋予环境安全的一次性使用。关键词：膜，氢氧化物，燃料电池，电池，固体电解质，碱性，聚合物电解质
