这个小企业创新研究（SBIR）项目的更广泛的影响/商业潜力是将植物基石墨烯产品用作电池材料，以提高储能密度，减少充电时间并延长电池寿命。对社会的好处是，植物基材料可以促进电动汽车的采用，降低可再生能源的电网存储成本，从而可能提供更大的能源安全性。该材料的成本效益将促进石墨烯在其他先进技术领域的广泛应用，如复合材料，导电油墨，可印刷电子，催化，传感器和生物医学设备，从而推动纳米技术的前沿。该SBIR第一阶段项目提出开发一种绿色可持续的工艺，使用丰富的植物材料作为输入，生产具有上级物理属性的极高纯度石墨烯。这项可行性研究将证明，高质量的SP2 Hybrid石墨烯可以用植物为基础的原材料制造，成本低于目前的石墨烯生产方法，并且是环境可持续的。目前石墨烯的生产，例如液体/化学剥离，使用源自不可再生资源的起始材料。拟议的工艺利用丰富的木薯作物作为原料，在美国和海外作为商品销售。 SP2 Hybrid石墨烯性能的初步样品已由第三方验证，具有4倍的表面积（2956 m2/g）和高达5X（5.0 cm 3/g）当前溶液的孔体积，作为电池和超级电容器中的电极材料提供更好的性能。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值进行评估而被认为值得支持和更广泛的影响审查标准。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is applying a plant-based graphene product as a battery material to increase energy storage density, decrease charging times and extend battery life. The benefit to society is that the plant-based material may facilitate adoption of electric vehicles and reduce the grid storage cost of renewable energy, potentially providing greater energy security. The proposed material's cost-efficient nature will facilitate broader adoption of graphene in other advanced technology areas such as composites, conductive inks, printable electronics, catalysis, sensors, and biomedical devices, thereby pushing nanotechnology frontiers.This SBIR Phase I project proposes to develop a green sustainable process using an abundant plant material as input and producing extremely high purity graphene with superior physical attributes. This feasibility research will demonstrate that high-quality SP2Hybrid graphene can be manufactured from a plant-based raw material at lower costs than current methods of graphene production and is environmentally sustainable. Current production of graphene, such as liquid/chemical exfoliation, uses starting materials derived from non-renewable resources. The proposed process utilizes an abundant cassava crop as feedstock sold as commodity in the US and overseas. Preliminary samples of SP2Hybrid graphene properties have been validated by third parties to have 4X the surface area (2956 m2/g) and up to 5X (5.0 cm3/g) the pore volume of current solutions, offering better performance as an electrode material in batteries and supercapacitors.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.
