The invention relates to the technical field of sodium ion battery material preparation, in particular to a high-performance hard carbon negative electrode material and a preparation method and application thereof.The preparation method comprises the following steps that S1, porous carbon and liquid asphalt are mixed, a binder, a conductive agent and a dispersing agent are added, and an active substance is obtained; and S2, performing ball milling on the active substance, coating the surface of a copper foil with the active substance, drying, covering the surface of the active substance with a layer of copper foil to form a copper foil-active substance-copper foil structure, and performing high-temperature calcination to obtain the high-performance hard carbon negative electrode material. The hard carbon negative electrode material prepared by the method shows relatively high reversible capacity and first coulombic efficiency in the sodium-ion battery, has good cycling stability, and is beneficial to large-scale production of the sodium-ion battery negative electrode material.

The utility model discloses a multifunctional cowshed environment regulation and control device, including the cowshed body of setting, the cowshed body top inside installation has the slide rail, the slide rail inside slide connection has the sliding block, the water storage tank is connected through the installation component under the sliding block, the water storage tank lower portion is provided with the regulator and the control box, the control box inside installation has the motor, the regulator and motor are electric connection, the motor output end is connected with the rotating shaft, the rotating shaft outside installation has the fan. This multifunctional cowshed environment regulation and control device, the whole device is slid with the slide rail and the sliding block, can move along the cowshed body top, the whole moving structure breaks the limitation of fixed installation, greatly expands the coverage of environmental regulation, reduces the problem that the cowshed use space is affected by setting multiple detection structures, the fan operation realizes the air circulation in the cowshed, and the whole structure is simple, reduces the problem that the maintenance cost increases by setting complex system.
