项目摘要
The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to help all market sectors where lithium ion (Li-ion) batteries are currently used, such as aerospace & defense, transportation, medical, oil & gas, and consumer electronics. Li-ion, the highest-performing commercially available battery technology, currently accounts for 37% of the $23.5 billion battery market. However, it has currently reached the maximum performance that physics and chemistry allow. For the electric vehicle market, these performance limits would require a 1200 lb, $15,000 battery pack in an all-electric sedan, and therefore broad deployment in SUVs, pickup trucks or heavy-duty military or commercial vehicles would be commercially and economically impractical. The envisioned battery technology uses a different chemistry that potentially offers four times better storage capability than Li-ion batteries and is much lighter, leading to new economically feasible electric cars. Through unique partnerships with industry and technology commercialization, this PFI-TT project will enable testing, evaluation & refinement of the proposed technology, production scale-up and a battery prototype.The proposed project focuses on development of Li-S batteries using a commercially-viable carbonate electrolyte, the liquid responsible for transporting Li+ ions between electrodes. The past R&D efforts for Li-S use ether electrolytes that have low boiling point (~42 degrees C) making them extremely flammable and commercially non-viable. Fundamental investigations on the role of the sulfur phase in altering the reaction mechanism have led to the development of sulfur cathodes that successfully function in carbonate electrolytes - like those used in commercial Li-ion batteries for three decades - with a stable four-fold higher capacity at the material level for 1000+ cycles. This PFI-TT project will undertake development activities to reduce battery weight and increase sulfur loading based on success metrics provided by potential partners during preliminary customer discovery, with the objective to achieve four-fold improvement in the "device-level" specific capacity. The proposed technology will also eliminate dead weight (up to 25% of electrode weight) of binders and current collectors' passive components used in current devices and consequently eliminate slurry processing, a necessary processing step needed for current powder-based electrodes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该创新合作伙伴关系 - 技术转化 (PFI-TT) 项目的更广泛影响/商业潜力是帮助目前使用锂离子 (Li-ion) 电池的所有市场领域,例如航空航天和国防、运输、医疗、石油和天然气,以及消费电子产品。锂离子电池是性能最高的商用电池技术,目前占 235 亿美元电池市场的 37%。 不过目前已经达到了物理和化学允许的最大性能。 对于电动汽车市场来说,这些性能限制需要在全电动轿车中配备 1200 磅、价值 15,000 美元的电池组,因此在 SUV、皮卡车或重型军用或商用车辆中广泛部署在商业和经济上都是不切实际的。设想的电池技术使用不同的化学物质,其存储能力可能是锂离子电池的四倍,而且重量更轻,从而催生新型经济可行的电动汽车。通过与行业和技术商业化的独特合作,该 PFI-TT 项目将能够测试、评估和完善拟议技术、扩大生产规模和电池原型。该拟议项目重点开发使用商业化锂硫电池。可行的碳酸盐电解质,负责在电极之间传输锂离子的液体。过去的锂硫研发工作使用低沸点(约 42 摄氏度)的醚电解质,使其极易易燃且在商业上不可行。对硫相在改变反应机制中的作用的基础研究导致了硫阴极的开发,这些阴极成功地在碳酸盐电解质中发挥作用——就像商业锂离子电池中使用了三十年的那些——具有稳定的四倍高容量在材料层面上循环 1000 多次。 该PFI-TT项目将根据潜在合作伙伴在初步客户发现过程中提供的成功指标,开展减轻电池重量和增加硫负载的开发活动,目标是实现“设备级”比容量提高四倍。所提出的技术还将消除电流器件中使用的粘合剂和集电器无源元件的自重(高达电极重量的 25%),从而消除浆料加工,这是当前粉末基电极所需的必要加工步骤。该奖项反映了通过使用基金会的智力价值和更广泛的影响审查标准进行评估,NSF 的法定使命被认为值得支持。
