The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project includes providing a high-throughput system for recycling critical metals like cobalt to reduce the conventional energy-intensive mining and refining processes used to produce materials for manufacturing today. Most importantly, this project will help secure a supply of critical materials, reducing the United States’ reliance on foreign supply chains and guaranteeing a secondary source of battery materials. A new, domestic supply will also reduce the social and human health impacts associated with artisanal mining, and significantly reduce the environmental impact of batteries and electric vehicles.This SBIR Phase II project proposes to (1) validate novel electro-extraction nanotechnology based separations technology in the battery recycling and cobalt mining space, and (2) validate a new, value-added product (a battery cathode precursor material) for this rapidly growing market, rendering the conventional refining stages unnecessary. The proposed electroextraction process utilizes flow-through water electrolysis to produce high local concentrations of hydroxide to precipitate transition metals as metal hydroxides. This understanding will allow tuning the device operating conditions for metal or mixed-metal specific precipitation, for example, the precipitation of Ni-Mn-Co hydroxides at battery stoichiometries or highly selective precipitation of individual metals.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.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力包括提供一个高通量系统，用于回收关键金属（例如钴），以减少用于生产当今制造材料的常规能源密集型采矿和炼油过程。最重要的是，该项目将有助于确保关键材料的供应，从而减少美国对外国供应链的缓解，并保证电池材料的次要来源。新的国内供应还将减少与手工采矿相关的社会和人类健康影响，并大大降低电池和电动汽车的环境影响。这项SBIR II期项目提案提案（1）验证新型的电脱水学分离技术在基于电池回收的电池回收和cobalt Mining Space，以及（2）型号的Product（2）级别的Product（2）ADAD ADAD ADAD ADAD ADAD ADAD APAD ADAD APAD ADAD APAD ADAD A.不必要的市场不必要的市场，使传统的精炼阶段不必要。拟议的电萃取过程利用流通水电来产生局部浓度的氢氧化物，以将过渡金属作为金属氢氧化物沉淀。这种理解将允许调整金属或混合金属特异性降水的设备工作条件，例如，在电池石化膜片或高度选择性的单个金属的降水中，Ni-Mn-CO氢氧化物的降水量。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识优点和广泛影响的评估来通过评估来进行评估的珍贵支持。
