SBIR Phase I: Novel Low Lattice Energy, Plasticizing Lithium Salt for Rechargeable Solid Lithium Batteries

9860114这个小型企业创新研究项目将研究将一种用于可充电固体锂电池的新锂盐商业化的可行性。由于与电池的关键部件--固体聚合物电解液(SPE)商业化有关的问题，这些电池无法商业化。需要新的材料来改善固相萃取的性能，同时保持简单和具有成本效益的配方。为此，该项目将概述一种新的锂盐的设计、合成和测试，它将改进和简化任何给定的固相萃取。提出了一种多功能盐，它结合了低晶格能和塑化能力这两个关键特性，既能改善SPE的导电性，又能改善SPE的形态。该盐将使用记录充分的程序合成，配制成测试SPE，并与行业标准的商业可获得的锂盐双(三氟甲基磺酰亚胺)锂进行评估和比较。这项第一阶段研究计划将集中在目前使用的盐与本提案中描述的新盐之间的直接比较。固态离子导电电解质可以在广泛的商业应用中使用。灵活的可充电锂电池将用于移动通信设备、笔记本电脑和电动汽车。在电池行业之外，离子导电膜将应用于电化学传感器和人造肌肉。

9860114 This Small Business Innovation Research project will study the feasibility of commercializing a new lithium salt for Rechargeable Solid Lithium Batteries. These batteries are not commercially available, due to the problems related to the commercialization of a key part of the battery, the solid polymeric electrolyte (SPE). New materials are needed that will improve the performance of the SPE while maintaining a simple and cost effective formulation. To that end, this project will outline the design, synthesis and testing of a new lithium salt that will improve and simplify any given SPE. A multifunctional salt is presented that will both improve the conductivity and the morphology of the SPE by combining two key features, low lattice energy and plasticizing ability. The salt will be synthesized using well-documented procedures, formulated into test SPEs and evaluated and compared with the industry-wide standard commercially available lithium salt, lithium bis(trifluoromethylsulfonyl)imide. This Phase I research plan will concentrate on direct comparisons between the salt used currently and the new salt described in this proposal. Solid state ion-conducting electrolytes can be used in a wide range of commercial applications. Flexible rechargeable lithium batteries will be used in mobile communication equipment, laptop computers, and electric vehicles. Outside of the battery industry, ion-conducting membranes will be applied to electrochemical sensors and artificial muscles.
