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

电化学储能（EES）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，并且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途的EES技术之一，因为它们可以在短时间内（不到几分钟）快速充放电，并能够快速响应自然灾害造成的电力中断，从而提高加拿大的电网弹性和能源安全。然而，目前的商用超级电容器通常提供10 Wh/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，由刘健博士领导的UBC研究人员与位于不列颠哥伦比亚省的清洁技术公司Atlas Power Technologies合作，将使用创新的材料和电解质方法开发一种新型超级电容器，该电容器具有70 Wh/kg的高能量，低至-70°C的优异存储性能，以及固有的高安全性。高能量和耐低温超级电容器技术将被转让给阿特拉斯电力技术公司，并纳入其在bc省的超级电容器制造工厂，该工厂将创造110个新的高水平工作岗位，到2023年年产11兆瓦时超级电容器。这种加拿大制造的超级电容器将加速清洁能源的转型和部署，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.
