Description

technical field [0001] The invention relates to the technical field of secondary batteries, in particular to a copper-air molten salt secondary battery and a preparation method thereof. Background technique [0002] A secondary battery, also known as a rechargeable battery, is a battery that can be repeatedly charged and discharged and used many times. Compared with non-reusable primary batteries, secondary batteries have the advantages of low cost and less environmental pollution. At present, the main secondary battery technologies include lead-acid batteries, nickel-chromium batteries, nickel-metal hydride batteries, and lithium-ion batteries. Among them, lithium-ion batteries are the most widely used, and daily-used mobile phones, notebook computers, digital cameras, etc. are all powered by lithium-ion batteries. The core components of a lithium-ion battery usually include a positive electrode, a negative electrode, and an electrolyte. It realizes electrical energy stor...
