This PFI: AIR technology translation project will facilitate the development and commercialization of graphene and graphene-silicon composite anodes in next-generation Lithium-ion batteries, with significantly higher energy density as compared to their present-day counterparts. The proposed technology is important because Lithium-ion batteries need significant improvement to keep pace with the needs of customers who are demanding high specific energy, long service life, high power on demand and quick charging. If scalable, the proposed graphene technology could help satisfy these requirements and could find widespread use in various applications such as wearables (smart watches and google glass), portable electronics (cell phones, laptops), unmanned aerial vehicles as well as electric vehicles and grid storage. This project will result in a scaled-up demonstration of a minimally viable product (MVP). Based on preliminary testing, this MVP is expected to deliver volumetric and gravimetric energy densities of up to ~1000 Watt-hour/liter and ~650 Watt-hour/kilogram respectively. These performance metrics are 2-3 fold superior to the incumbent graphite anode technology which is extensively used in today's Lithium-ion batteries.This project addresses the following technology gap(s) as it translates from research discovery toward commercial application: (1) Methods to achieve scalable (roll-to-roll) manufacturing of graphene electrodes for Lithium batteries and (2) Assembly of the electrodes into larger format pouch/cylindrical cells that can deliver the voltage and capacity-ratings of various end-use applications. To address manufacturing, the team will develop novel aqueous electrode slurries that can be deposited in a scalable manner using state-of-art doctor blade and slot-die coating methods. The deliverable for this project will be a minimally viable product (pouch and cylindrical cell batteries) that can be subjected to third-party validation and also field-tested by potential customers. This will facilitate joint development agreements with customers and private investors to begin production at industrially relevant scales. The students (1 graduate and 2 undergraduates) involved in the project will develop important skill-sets including scalable electrode manufacturing, pouch/cylindrical cell assembly and system level testing of the prototypes. In a pure laboratory environment, such studies are often excluded, thereby preventing the students from experiencing the stringent standards and rigors of the industry. Additionally, the students will actively participate in conferences and other networking events where they will have extensive networking opportunities and the potential to meet like-minded entrepreneurial students and industry experts.

该PFI：空气技术翻译项目将有助于下一代锂离子电池中石墨烯和石墨烯 - 硅综合阳极的开发和商业化，与当今的同行相比，能量密度明显更高。提出的技术很重要，因为锂离子电池需要显着改进，以跟上要求高能量，长期使用寿命，高功率按需和快速充电的客户的需求。如果可扩展，则提议的石墨烯技术可以帮助满足这些要求，并可以在各种应用中找到广泛使用，例如可穿戴设备（智能手表和Google Glass），便携式电子设备（手机，笔记本电脑），无人驾驶飞机以及电动汽车以及电动汽车和网格存储。该项目将导致最小可行的产品（MVP）的扩展演示。根据初步测试，该MVP有望提供容量和重量的能量密度，分别为〜1000瓦小时/升和〜650瓦小时/千克。 These performance metrics are 2-3 fold superior to the incumbent graphite anode technology which is extensively used in today's Lithium-ion batteries.This project addresses the following technology gap(s) as it translates from research discovery toward commercial application: (1) Methods to achieve scalable (roll-to-roll) manufacturing of graphene electrodes for Lithium batteries and (2) Assembly of the electrodes into larger format pouch/cylindrical cells that can提供各种最终用途应用的电压和容量评价。为了解决制造业，该团队将开发新型的水电浆，可以使用最先进的医生刀片和插槽涂层方法以可扩展的方式沉积。该项目的可交付方式将是一种最低限度可行的产品（小袋和圆柱电池电池），可以经过第三方验证，也可以受到潜在客户的现场测试。这将促进与客户和私人投资者的共同开发协议，以在工业相关规模开始生产。该项目涉及的学生（1名毕业生和2名本科生）将开发重要的技能集，包括可扩展的电极制造，小袋/圆柱细胞组件和原型的系统水平测试。在纯粹的实验室环境中，这种研究通常被排除在外，从而阻止学生体验严格的标准和严格的行业。此外，学生将积极参加会议和其他网络活动，在那里他们将拥有广泛的网络机会，并有可能与志趣相投的企业家学生和行业专家见面。
