High-Energy and Low-Temperature Pseudocapacitor Energy Storage Technology for Post-Pandemic Green Economic Recovery

电化学储能技术是我们日常生活中不可或缺的一部分，支持电动汽车、便携式备用电源和智能电网系统，在利用许多可再生能源方面至关重要。超级电容器是最有前景的EES技术之一，因为它们可以在短时间(不到几分钟)内快速充电和放电，并能够对自然灾害造成的电力中断做出快速反应，从而提高加拿大电网的弹性和能源安全。然而，目前的商用超级电容器通常提供10Wh/kg的低能量密度，并且在低温下性能较差。为了克服这些限制，刘健博士领导的UBC研究人员与总部位于卑诗省梅蒂斯的清洁技术公司Atlas Power Technologies合作，将使用创新材料和电解液方法开发一种新型超级电容器，具有70Wh/kg的高能、低至-70°C的出色存储性能和固有的高安全性。高能和耐低温超级电容器技术将转移到Atlas Power Technologies，并纳入其位于不列颠哥伦比亚省的超级电容器制造厂，这将创造110个新的高口径工作岗位，到2023年将拥有11兆瓦时超级电容器的年产量。这种加拿大制造的超级电容器将加速清洁能源的过渡和部署，特别是在偏远社区和加拿大北部，并以绿色和公平的方式大力支持大流行后的经济复苏。

Electrochemical energy storage (EES) technologies are an indispensable part of our daily lives, supporting electric vehicles, portable backup power supplies, and intelligent grid systems, and are essential in harnessing many renewable energy sources. Supercapacitors are among the most promising EES technologies because they allow rapid charge and discharge in a short period (less than minutes) and enable fast responses to power interruption from natural disasters, thus improving grid resilience and energy security in Canada. However, current commercial supercapacitors typically deliver a low energy density of 10 Wh/kg and poor performance at low temperatures. To overcome these limitations, UBC researchers led by Dr. Jian Liu, in collaboration with Atlas Power Technologies, a Métis-led, B.C.-based clean technology company, will use innovative materials and electrolyte approaches to develop a new type of supercapacitors with the high energy of 70 Wh/kg, excellent storage performance down to -70 °C, and intrinsic high safety. The high-energy and low-temperature tolerant supercapacitor technology will be transferred to Atlas Power Technologies and incorporated into their supercapacitor manufacturing facility in B.C., which will create 110 new high-caliber jobs and have an annual production of 11 MWh supercapacitors by 2023. This made-in-Canada supercapacitor will accelerate clean energy transition and deployment especially in remote communities and northern Canada and strongly support the post-pandemic economic recovery in a green and equitable way.
