The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to demonstrate the feasibility of Battery Resourcers recycling process on a scale that has commercial significance. This will further allow Battery Resourcers to scale its process such that it can be a player in the lithium ion battery recycling market place. Battery Resourcers' ultimate goal is into increase recycling rates of spent Li-ion batteries by providing an economically viable domestic recycling option. Additionally, Battery Resourcers process produces low cost cathode materials for the battery industry which may ultimately further enable green technologies like solar, wind and electric vehicles.This SBIR Phase 1 award proposes to scale the Battery Resourcers recycling process from 50kg to 0.5 tons of spent Li-ion batteries. The proposed research focuses on process speed, safety and the quality of the recovered materials. Rate limiting steps in Battery Resourcers recycling process will be studied with an effort to improve process speed. Specifically, Battery Resourcers will look at new filtering methods for the solutions generated in its process. A method to safety shred Li-ion batteries is examined by controlling the atmosphere and removing the batteries' stored energy. Finally, the production of quality cathode materials from spent Li-ion batteries is scaled from 50kg to 0.5 tons. Battery Resourcers' goal is to produce commercial quality cathode powder on a scale that matters to industry.

这个小企业创新研究（SBIR）项目的更广泛的影响/商业潜力是证明电池资源回收过程在具有商业意义的规模上的可行性。这将进一步允许Battery Resourcers扩大其流程，使其能够成为锂离子电池回收市场的参与者。Battery Resourcers的最终目标是通过提供经济可行的国内回收选择来提高废旧锂离子电池的回收率。 此外，Battery Resourcers工艺为电池行业生产低成本的阴极材料，最终可能进一步推动太阳能、风能和电动汽车等绿色技术的发展。SBIR第一阶段合同建议将Battery Resourcers回收工艺从50公斤扩大到0.5吨。拟议的研究重点是加工速度、安全性和回收材料的质量。将研究电池资源回收过程中的限速步骤，以提高过程速度。具体来说，Battery Resourcers将研究新的过滤方法，以解决其过程中产生的解决方案。研究了一种通过控制气氛和去除蓄电池储能来安全粉碎锂离子电池的方法。最后，从废旧锂离子电池中生产优质正极材料的规模从50公斤扩大到0.5吨。 Battery Resourcers的目标是以对行业至关重要的规模生产商业质量的阴极粉末。
