SBIR Phase II: Low Cost, High Performance Electrolytes for Lithium-ion Batteries

这一小型企业创新研究（SBIR）第二阶段项目准备通过使用一类新的低成本、高性能锂盐，为锂离子电池引入上级电解质。 目前，电池的成本不仅受到锂盐的高成本的影响，而且还受到限制电池寿命的相对较低的稳定性的影响。 如果成功的话，这些电解质将在第二阶段项目下开发，将具有更高的离子电导率和上级热和电化学性能，这将是非常有吸引力的，特别是适用于电动汽车和混合动力汽车（EV/HEV）的全尺寸锂离子电池。 该公司早期成功开发了一种新的两步合成策略，以制备这些含有两个锂离子的盐，而目前使用的盐中含有一个锂离子，该项目将优化和扩大合成工艺，从而以更低的成本生产这些盐，同时满足所有主要规格，包括高迁移数，电池在零度以下的温度下正常工作的吸引人的特性。 该项目还将进一步探索合成方法，以提供更低的成本来占领小型锂电池市场，其中应用于计算机，手机，相机和医疗设备。 该项目的更广泛/商业影响将在可充电电池行业领域，特别是在EV/HEV的竞技场。 成本、性能和电池寿命是该行业的主要驱动力。 低成本、高性能和增强稳定性的电解质的可用性将有助于降低成本，使电池驱动的应用对用户来说更实惠。 该项目的成功成果预计将有助于美国政府对可再生能源的重视，特别是能源部关于先进电池的路线图，这些电池具有更强大，更稳定的化学性质和成本效益。

This Small Business Innovation Research (SBIR) Phase II project is poised to introduce superior electrolytes to the lithium-ion batteries by using a new class of low-cost, high-performance lithium salts. Currently, the cost of batteries is impacted not only by the high cost of the lithium salts, but also their relatively lower stability that limits battery lifetime. If successful, these electrolytes, to be developed under this Phase II project, will possess higher ionic conductivity and superior thermal and electrochemical properties that will be very attractive particularly for full size lithium-ion batteries applicable to electric vehicles and hybrid electric vehicles (EV/HEV). Building on the company's earlier success in developing a novel two-step synthetic strategy to prepare these salts which contain two lithium ions versus one in currently used salts, this project will optimize and scale up the synthetic process leading to the production of these salts at much lower cost, while meeting all principal specifications, including high transference number, an attractive property of a battery to function properly at subzero temperatures. This project will also further explore synthetic approaches to deliver even lower cost to capture the small size lithium battery market, where the applications are in computers, cell phones, cameras, and medical devices. The broader/commercial impact of this project will be in the area of the rechargeable battery industry, especially in the arena of EV/HEV. Cost, performance and battery life are major drivers of this industry. The availability of electrolytes of lower cost, high performance and enhanced stability will contribute to cost reduction needed to make battery driven applications more affordable to users. The successful outcomes of this project are expected to contribute to the US Government's emphasis on renewable energy and particularly, the Department of Energy's roadmap on advanced batteries with more robust and stable chemistries and cost effectiveness.
