Description

technical field [0001] The invention relates to a technology in the field of zinc-lithium ion batteries, in particular to a 3D printing one-time molding water-based zinc-ion battery and its realization method. Background technique [0002] Traditional lithium-ion batteries need to be prepared through procedures such as cutting, coating, drying, liquid injection, and packaging. The process is complicated, the cycle is long, and the cost is high. Lithium-ion batteries currently on the market can be divided into cylindrical, button-type, and square according to their shapes. Lithium-ion batteries of different shapes require different molds and machines, resulting in a lot of waste of resources and space. Moreover, because the organic electrolyte used is volatile, flammable, and reacts with water and oxygen, traditional lithium-ion batteries must strictly control the content of oxygen and water in the environment during assembly, and there are still safety issues after assembly....
