SBIR Phase I: Development of Polymer-Based Hydroxide Conducting Membranes

这个小企业创新研究第一阶段项目将建立一种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），它具有高OH-导电性（10-2 S/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导电固体电解质。在初步研究中，revo已经确定了两种可能的合成hem的方法。本研究的重点将是评估这些hem的氢氧化物电导率、机械强度和成膜能力，以及优化这些参数之间的关系。将确定具有成本效益的制造方法，并演示温度对性能的影响。初步结果表明，这些hem具有填补碱性电池行业巨大市场需求的巨大潜力。由于目前还没有与之竞争的氢氧化物导电膜技术，这种材料将在碱性电池工业中立即得到应用。它将进一步应用于revo锌空气燃料电池和氢燃料电池的混合类。这将消除防止腐蚀或液体电解质泄漏的需要，并增加电池的能量和功率密度。特别是，这种材料可以大大减少碱性电池的材料和制造成本，同时赋予环境安全的一次性。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

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
