Cleaner Energy Storage: Cradle-To-Gate Life Cycle Assessment Of Aluminum-Ion Batteries With An Aqueous Electrolyte
FRONTIERS IN ENERGY RESEARCH(2021)
摘要
In the context of growing demand on energy storage, exploring the holistic sustainability of technologies is key to future-proofing our development. In this article, a cradle-to-gate life cycle assessment of aqueous electrolyte aluminum-ion (Al-ion) batteries has been performed. Due to their reported characteristics of high power (circa 300Wkg(-1) active material) and low energy density (circa 15Wh kg(-1) active material), these results were compared with those of supercapacitors (per kW). Initial findings suggest these aluminum-ion cells have fewer environmental impacts than commercial supercapacitors, hence offering a more environmentally sensitive energy storage technology solution. Al-ion batteries are in their early development, and this result shows a strong argument for continuing research into this technology alongside other emerging energy storage systems.
