Description

Technical field [0001] The present invention relates to the technical field of zinc ion batteries, and specific to a defective type K 0.5 Mn 2 O 4 Nanomaterials and preparation methods, zinc ion batteries. Background technique [0002] Energy and environments are two major issues that have a human survival and social development in today's human survival, due to the continued demand of portable electronic products and electric vehicles, the battery is widely used as a high-efficiency electrochemical energy storage device. In the secondary battery, it is mainly based on anhydrous organic solution as an electrolyte, which enables a higher energy density. However, organic solvents are usually poisonous and flammable, so in the process of use, there is a big safety problem in the battery, and the battery must be produced in anhydrous environment to cause increased production cost, thereby limiting the possibility of wide application. It is expected to further reduce costs and improve...
