The invention relates to the field of fire extinguishing agents special for lithium ion batteries, in particular to a high-cooling-performance water-based fire extinguishing agent for a lithium ion battery and a preparation method of the high-cooling-performance water-based fire extinguishing agent, and the high-cooling-performance water-based fire extinguishing agent comprises the following components in parts by mass: 4-5.4 parts of an organic silicon surfactant, 0.1-0.25 part of a fluorine surfactant, 0.1-2 parts of a hydrocarbon surfactant, 0.5-1.6 parts of polyhydric alcohols, 0.3-4 parts of esters, 0.001-0.002 part of metal salt and 90-94 parts of water. The water-based fire extinguishing agent special for the lithium ion battery can efficiently restrain fire disasters of the lithium ion battery, and the fine water mist water-based fire extinguishing agent can further enhance the lasting cooling effect, reduce the surface tension of water, improve the water mist atomization effect and improve the stabil
