Air bound is exhausted, and surface does not have the generation of the impurity such as lithium carbonate, lithium nitride.After metal lithium bands deposit, spray equipment is in metal lithium bands
Surface spraying organic matter prepares one layer of organic protection layer.Patent CN201645921U is using the method reacted in lithium band exposure atmosphere
Protective layer is prepared, not only not fine and close but also thickness and uniformity can not be precisely controlled protective layer prepared by this method.This practicality
The device of new offer be more convenient control protective layer thickness and the uniformity, at any time can by varying organic solution component,
Solution concentration and spraying rate change protective layer.Protective layer can effectively completely cut off the reaction of electrolyte and lithium metal, stablize gold
