High-performance quasi-solid-state zinc-ion capacitors coupling carbonaceous electrodes with eutectic hydrogel electrolytes

锌离子电容器是一种面向电网应用的新型储能技术，具有高能量和功率密度、超长循环寿命、低成本等优点。然而，由于碳材料和含水电解质的结构和性能限制，目前最先进的锌离子电容器存在低存储容量和较差的循环性能。为了应对这一挑战，加拿大不列颠哥伦比亚大学的Jian Liu博士团队和德国帕德博恩大学的Nieves博士López-Salas团队提出将新型碳质电极与共晶水凝胶电解质结合起来，开发新一代锌离子电容器，显著提高能量和功率密度以及寿命。这项国际合作将利用材料科学和能源存储技术方面的专业知识来加速锌离子电容器的发展。该项目的成功将开发一种新的储能设备，用于并网，加速清洁能源转型，并为加拿大清洁能源部门培养未来的高素质人才。

Zinc-ion capacitors are new energy storage technology for grid applications and have great potential for high energy and power density, ultralong cycling lifetime, and low cost. However, state-of-the-art zinc-ion capacitors present low storage capacity and poor cycling performance due to structure and property limitations in carbon materials and aqueous electrolytes used. To address this challenge, Dr. Jian Liu's team at the University of British Columbia (Canada) and Dr. Nieves López-Salas's team at Paderborn University (Germany) propose to couple novel carbonaceous electrodes with eutectic hydrogel electrolytes to develop new-generation zinc-ion capacitors with significantly improved energy and power density and lifetime. This international collaboration will leverage expertise in materials science and energy storage technology to accelerate the development of zinc-ion capacitors. The success of the project will develop a new energy storage device for integration into the grid, accelerate the clean-energy transition, and train future highly qualified personnel for the clean-energy sector in Canada.
