Global energy demand is growing rapidly and significantly as energy, the key ingredient in all sectors of modern economy, has invaded the quality of life today due to our dependency on its abundant and uninterrupted supply. Fabrication of economically viable and environment friendly high energy storage device is one of the major challenges for the current scientific community. To meet the urgent need for environment-friendly, high efficiency energy storage and conversion devices for high-power electronic devices, backup power supplies, and electric vehicles, efforts have been made to develop batteries, fuel cells, and supercapacitors (ECs) with the aim of replacing fossil fuel use. Supercapacitors have received much attention because they can simultaneously achieve high power and high energy densities and have shown great promises for use in electronic devices, backup power supplies, and electric vehicles. A supercapacitor device is fabricated using two electrodes, immersed in an electrolyte, like batteries, but separated by an insulated porous material such as polymer membranes. In this project, nanostructure translon metal oxides (TMO) thin films will be grown on aluminum since it will be used as charge collectors. These thin films will be further modified with carbon nanotube, graphene or conducting polymer, separately, to create nanostructured composite thin films supercapacitor electrodes with improved electronic and ionic conductivities. Above all, these nanocomposite thin films electrodes will utilize both energy storage mechanisms of pseudocapacitors and electrical double layer capacitors (EDLC) due to the presence of both TMO and carbon materials. The fabricated electrodes will be used to assemble lab-scale supercapacitor devices and characterize them systematically. The nanocomposite materials will be fabricated by decomposing superhydrophobic organic-inorganic network which is completely innovative; hence the outcome of the research is patentable. Due to the possibilities to control of the size of the nanopatterns on aluminum using anodized aluminum pore (AAO) and micro-nanosphere lithography, the outcome of the research will enable us to fabricate a supercapacitor device having light weight, small size, low cost with high energy, high power and long cycle life. Similarly, use of nanocrystalline cellulose (NCC), a product of wood, in energy application would bring fundamental knowledge as well as practical applications for Quebec, Canada as well as internationally. This new knowledge will be transferred through training of four HQP’s who expected to be graduated within five years. Moreover, this transfer will be disseminated through publications in international journals.

全球能源需求正在快速而显着地增长，因为能源是现代经济各部门的关键组成部分，由于我们依赖于其丰富且不间断的供应，能源已经影响到了人们的生活质量。为满足大功率电子设备、备用电源和电动汽车对环境友好、高效的能量存储和转换器件的迫切需求，是当前科学界面临的重大挑战之一。电池、燃料电池和超级电容器以取代化石燃料为目标的超级电容器因其可以同时实现高功率和高能量密度而受到广泛关注，并在电子设备、备用电源和电动汽车中显示出巨大的应用前景。使用两个电极制成，浸入电解质中，如电池，但由绝缘多孔材料（如聚合物膜）隔开。在该项目中，将采用纳米结构 Translon 金属氧化物（TMO）薄膜。这些薄膜将分别用碳纳米管、石墨烯或导电聚合物进行改性，以制造具有改进的电子和离子电导率的纳米结构复合薄膜超级电容器电极。由于 TMO 和碳材料的存在，薄电极将利用赝电容器和双电层电容器 (EDLC) 的储能机制，所制造的电极将使用薄膜来组装。实验室规模的超级电容器装置并系统地表征它们将通过分解超疏水有机-无机网络来制造，这是完全创新的；因此，由于可以控制纳米图案的尺寸，因此该研究成果是可申请专利的。利用阳极氧化铝孔（AAO）和微纳米球光刻技术，研究成果将使我们能够制造出重量轻、尺寸小、成本低、高性价比的超级电容器器件。同样，纳米晶纤维素（NCC）（一种木材产品）在能源应用中的应用将为魁北克省、加拿大乃至国际带来基础知识和实际应用。通过培训四名预计在五年内毕业的总部人员进行转移，而且这种转移将通过国际期刊上的出版物进行传播。
