The present disclosure provides a safe conductive coating slurry, a composite current collector and a preparation method thereof, and a battery, and belongs to the field of battery materials. The safe conductive coating slurry for the composite current collector comprises, in terms of mass fraction, 15-30 parts of a main material, the main material comprising microcrystalline glass; 10-30 parts of a binder; 10-20 parts of a solvent; 0.5-2 parts of a dispersing agent; 0.5-1 part of a wetting agent; and 0.5-1 part of a leveling agent. The coating slurry of the present disclosure comprises microcrystalline glass, which can simultaneously play the roles of a conductive coating and a safe coating by only coating one layer of coating, thereby simplifying the preparation process and the coating process; when combined with an electrode active material, the coating slurry does not cause the electrode active material to fall off; and the safe conductive coating has no cracking phenomenon. The technical problems of the prior art, such as the complexity of the slurry preparation process and the coating process when the two-layer structure of the conductive coating and the safe coating is coated on the composite current collector, the easy falling off of the electrode active material when combined with the electrode active material, and the easy cracking of the conductive coating, are avoided.

The invention belongs to the technical field of water conservancy and transportation engineering maintenance, and particularly relates to a ship lock concrete surface repairing coating in a seawater soaking environment and a construction method of the ship lock concrete surface repairing coating. Comprising a permeation anchoring bottom coating, a stress buffering middle coating and a super-weather-resistant protective surface coating which are sequentially arranged from inside to outside, and the permeation anchoring bottom coating is a bi-component epoxy-biomineralization composite system. The construction method of the ship lock concrete surface repairing coating comprises the steps that a base plane is diagnosed and cleaned; constructing a negative pressure microenvironment; carrying out in-situ vacuum dehydration and exclusion; negative-pressure prime coat leading-in is carried out; performing controlled ventilation and re-pressing permeation; and constructing a multi-layer system. According to the method, capillary water wedge resistance can be overcome under the condition that a dry base plane does not need to be stopped for a long time, deep penetration and high-strength anchoring of a repairing material to concrete microcracks are achieved, and the chloride ion penetration resistance and durability of a ship lock structure are greatly improved.
