1. A battery module with nano-composite coating, comprising:
at least one battery pack including a plurality of batteries and at least two busbars, each battery having a metal barrel body, two opposite ends of the metal barrel body of each battery being connected with two electrodes, an outer surface of the metal barrel body of each barrel-shaped battery being coated with a first nano coating, the first nano coating being composed of a first macromolecule waterproof coating, two busbars being respectively mounted to the two electrodes of each battery, and the plurality of the batteries being connected to the two busbars by a plurality of wires, so the plurality of the batteries being connected in series, each busbar and the electrodes of the plurality of the batteries connected to each busbar and exposed outside being coated with a second nano coating, the second nano coating being formed by successively coating a second macromolecule waterproof coating and the first macromolecule waterproof coating on surfaces of each busbar and the electrodes of the plurality of the batteries connected to each busbar and exposed outside; and
at least one circuit board being coated with a third nano coating, the third nano coating being formed by successively coating a first solution, the first macromolecule waterproof coating, the second macromolecule waterproof coating, a third macromolecule waterproof coating and a second solution on the at least one circuit board, the first macromolecule waterproof coating and the second macromolecule waterproof coating having different compositions, the first macromolecule waterproof coating and the third macromolecule waterproof coating having different compositions, and the first solution and the second solution having different compositions;
wherein the plurality of the wires are used for being soldered with each battery and each busbar, soldering positions among each wire, each battery and each busbar are coated with a fourth nano coating, the fourth nano coating is formed by coating the third macromolecule waterproof coating and the first macromolecule waterproof coating on the soldering positions among each wire, each battery and each busbar successively, the first macromolecule waterproof coating has a flowability larger than a flowability of the second macromolecule waterproof coating, the second macromolecule waterproof coating has a viscosity larger than a viscosity of the first macromolecule waterproof coating and the third macromolecule waterproof coating has a viscosity stronger than the viscosity of the second macromolecule waterproof coating and the first, second, third and fourth nano coatings have different compositions.
