Description

technical field [0001] The invention belongs to the field of application of novel green energy batteries in the electronics industry, communication industry, and electric vehicle power batteries, and in particular relates to a low-temperature inorganic molten salt aluminum ion supercapacitor battery and a preparation method thereof. Background technique [0002] In recent years, environmental pollution and the greenhouse effect have intensified, and non-renewable fossil fuels such as coal, oil, and natural gas have been increasingly depleted. Energy crisis and environmental protection have become two major problems facing the world. Therefore, the development and utilization of clean and renewable energy has become a hot spot in current research, and electric energy has become the key to the development and utilization of renewable energy because it is at the core stage of various energy conversions. Since Japan's SONY company successfully launched lithium-ion batteries, lit...
