Existing lithium-ion battery (LIB) technologies have serious cost and performance limitations that hinder the efficient use of renewable energy sources and the rapid transition to electric vehicles (EVs), hybrid electric vehicles (HEVs) and plug-in hybrid vehicles (PHEVs). Despite manufacturing demand for LIBs with greater power and increased specific energy density with longer runtimes, a stronger emphasis is being placed on the reduction of overall manufacturing cost in the new product development initiatives. Currently, the fabrication steps contribute to the overall LIB pack cost of $400-600 /kWh, which must still be reduced by 3-4x to be competitive with a conventional fuel tank in order to take its place in the widespread commercialization of HEVs, PHEVs and EVs. A tremendous effort is needed to reduce the processing cost, material cost, and amount of needed material to meet this goal. A novel carbon structure ? Carbon Micro/Nano Pillars (C-MNP) was invented by University of Massachusetts Lowell as the promising anode material for LIBs. The C-MNP anode based LIB demonstrates significant improvement in specific energy. Moreover, the new anode manufacturing process is well suitable for mass production and is compatible with existing battery manufacturing process offering to significantly reduce the investment for new battery manufacturing. The developed technology can provide automotive LIB manufacturers with a high performance and low cost anode manufacturing process, which will accelerate the widespread commercialization of electric vehicles. The proposed study will also contribute to a fundamental understanding of NIL technology, polymer carbonization, ion diffusion, and charge-surface interactions. Furthermore, the developed C-MNP structure and manufacturing process can be used for manufacturing of high performance cathode. Other potential applications include but are not limited to, crossover-proof membrane of fuel cells, electrodes of super capacitors, sensing surface of sensors for harsh environment, de- and anti-icing surfaces for wind turbines, and membrane for waste water purification. This I-Corps Teams project will help determine the market value based on the responses and insights of the automotive LIB manufacturers for the potential commercialization of proposed innovation. If successful, the developed technology could be licensed to automotive LIB manufacturers as a high performance and low cost anode manufacturing process or a small custom manufacturing company could be started to provide C-MNP based anodes to small/midsized LIB manufacturers as custom battery solutions.

现有的锂离子电池（LIB）技术具有严重的成本和性能限制，这阻碍了可再生能源的有效利用以及快速过渡到电动汽车（EVS），混合动力汽车（HEVS）和插电式混合动力汽车（PHEVS）。尽管制造对液化的需求具有更大的功率和更长时间的特定能量密度，但新产品开发计划中总体制造成本的降低仍在更加强调。 目前，制造步骤有助于整体LIB包成本为400-600美元 /千瓦时，必须将其减少3-4倍，以使其与传统的燃油箱具有竞争力，以便在HEV，PHEVS和EVS的广泛商业化中占据一席之地。需要巨大的努力来降低处理成本，材料成本和所需材料的数量以实现这一目标。一种新颖的碳结构？马萨诸塞大学洛厄尔大学发明了碳微/纳米支柱（C-MNP）作为有前途的阳极材料。基于C-MNP的LIB表现出特定能量的显着改善。此外，新的阳极制造过程非常适合大规模生产，并且与现有的电池制造工艺产品兼容，可大大降低新电池制造的投资。开发的技术可以为汽车LIB制造商提供高性能和低成本阳极制造工艺，这将加速电动汽车的广泛商业化。拟议的研究还将有助于对零技术，聚合物碳化，离子扩散和电荷表面相互作用的基本理解。此外，开发的C-MNP结构和制造过程可用于制造高性能阴极。其他潜在的应用包括但不限于燃料电池的交叉膜，超级电容器的电极，用于刺激性环境的传感器的传感表面，用于风力涡轮机的除染色表面以及用于废水净化的膜。这个I-Corps团队项目将根据汽车自由贸易商制造商的反应和见解来帮助确定市场价值，以实现拟议创新的潜在商业化。如果成功的话，可以将开发的技术作为高性能和低成本阳极制造工艺或小型定制制造公司许可，或者可以开始向中小型中小型LIB制造商提供基于C-MNP的阳极作为自定义电池解决方案。
