Slurry and preparation method and application thereof

The invention discloses slurry as well as a preparation method and application thereof. The slurry comprises a particle material, a linear material and a two-dimensional plane structure material, the length-diameter ratio of the linear material is greater than or equal to 200; the particle material, the linear material and the two-dimensional plane structure material are mutually crosslinked to form a net structure. The particle material, the linear material and the two-dimensional plane structure material are adopted to form good interface contact with the electrode active material and the current collector, a continuous three-dimensional transmission network is formed, and the heat conduction capability and the comprehensive performance are superior to those of a traditional heat conduction material. A complete heat conduction network enables the slurry to have good heat conductivity, and the heat dissipation performance of the battery is greatly improved. 本申请公开一种浆料及其制备方法和应用；该浆料包括粒子材料、线状材料和二维平面结构材料；所述线状材料的长
