This Small Business Research Innovation (SBIR) Phase I project will develop extrudable high performance solid polymer electrolyte (SPE) nanocomposites with high room temperature (RT) conductivity for lithium ion polymer battery applications. The proposed technology aims to offer a high performance SPE that will favorably compete in the secondary battery market and provide a safe alternative to lithium ion batteries that have problems with volatile liquid electrolyte leakage and fire hazards. The technology proposed herein aims to create a nanocomposite containing high concentrations of conductive moieties able to withstand thermal processing and provide a wide temperature use range. It is anticipated that the Aquazol-based copolymer nanocomposites will result in the first SPE with RT conductivity greater than currently available materials in an easy to process form. The development of a high performance solid polymer electrolyte that can compete with lithium ion and gel electrolytes without the safety and fire hazards has significant market value. Potential applications include high performance solid state batteries, chemical sensors, electrochemical capacitors, energy conversion by the fuel cells, electro-chromic displays or windows and analog memory devices. Significant environmental benefits are provided due to the limited quantities of volatiles used in the synthesis of copolymers and SPE nanocomposite production. In addition, these proposed novel Aquazol-based copolymers are a new addition to the family of poly(2-ethyl-2-oxzoline) products commercially available and their chemical and physical properties may find applications in fields such as personal care and medical products.

这个小型企业研究创新（SBIR）第一阶段项目将开发可挤出的高性能固体聚合物电解质（SPE）纳米复合材料，具有高室温（RT）电导率，用于锂离子聚合物电池应用。所提出的技术旨在提供一种高性能SPE，其将在二次电池市场中有利地竞争，并为具有挥发性液体电解质泄漏和火灾危险问题的锂离子电池提供安全的替代品。本文提出的技术旨在产生含有高浓度导电部分的纳米复合材料，其能够经受热加工并提供宽的温度使用范围。预计基于Aquazole的共聚物纳米复合材料将导致第一个SPE，其RT电导率大于易于加工形式的当前可用材料。开发能够与锂离子和凝胶电解质竞争而没有安全和火灾危险的高性能固体聚合物电解质具有显著的市场价值。潜在的应用包括高性能固态电池、化学传感器、电化学电容器、燃料电池的能量转换、电致变色显示器或窗口以及模拟存储器设备。由于在共聚物合成和SPE纳米复合材料生产中使用的挥发物数量有限，因此提供了显着的环境效益。此外，这些提出的新颖的基于Aquazole的共聚物是市售的聚（2-乙基-2-恶唑啉）产品家族的新成员，并且它们的化学和物理性质可以在诸如个人护理和医疗产品的领域中找到应用。
