SBIR Phase I: High Performance Aquazol-based Copolymer Nanocomposites for Lithium Ion Polymer Batteries

这个小型企业研究创新(SBIR)第一阶段项目将为锂离子聚合物电池应用开发具有高室温(RT)导电性的可挤压高性能固体聚合物电解质(SPE)纳米复合材料。这项拟议的技术旨在提供一种高性能的SPE，将在二次电池市场上有利地竞争，并为存在挥发性液体电解液泄漏和火灾危险问题的锂离子电池提供一种安全的替代方案。这里提出的技术旨在创造一种含有高浓度导电部分的纳米复合材料，能够承受热加工并提供广泛的温度使用范围。预计以水为基础的共聚纳米复合材料将以易于加工的形式产生第一个RT导电性大于当前可用材料的SPE。开发一种既能与锂离子和凝胶电解质竞争又不存在安全和火灾隐患的高性能固体聚合物电解质具有重要的市场价值。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和模拟存储设备。由于在合成共聚物和SPE纳米复合材料生产中使用的挥发物数量有限，因此提供了显著的环境效益。此外，这些新型的基于水分子的共聚物是市场上可获得的聚(2-乙基-2-恶唑啉)产品家族的新成员，其化学和物理性能可能会在个人护理和医疗产品等领域得到应用。

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.
