Abstract: The present disclosure discloses a prelithiation reagent for a lithium-ion battery (LIB), and a preparation method therefor and use thereof. The prelithiation reagent for the LIB has a chemical formula of Li5FeO4@C; and the prelithiation reagent for the LIB has a structure of secondary particles generated from the agglomeration of Li5FeO4 primary particles, and carbon is coated on a surface of the Li5FeO4 primary particles. In the present disclosure, a carbon source is mixed with a soluble salt of Fe, such that Fe ions are attached to the carbon source; then aqueous ammonia is added, such that a hydroxide with small particles and high dispersibility is generated; and then a solvothermal reaction is conducted to obtain a nano-scale oxide.

Abstract: A refrigerator (100) having an air blower (102) located downstream of a transverse side of an evaporator (150) is provided. The refrigerator includes: a cabinet defining a cooling chamber (133) and at least one storage compartment, the evaporator (150) arranged in the cooling chamber (133), and the air blower (102) arranged on the transverse side of the evaporator (150) and located downstream of the evaporator (150) in an airflow path. The air blower (102) does not occupy a space behind or in front of the evaporator (150), which reduces a space occupied by the cooling chamber (133) in a front-rear direction, and ensures the thickness of a foamed material between the rear of the cooling chamber (133) and a housing of the cabinet.

Abstract: The automatic door opening and closing device includes: a housing having a mounting space formed therein; and a pushing and rotating assembly provided in the mounting space and having a push rod controlled to be telescopic and a guide rod which extends outwards from the mounting space and is controlled to be movable; wherein the push rod is configured to push open a door of the refrigerator when controlled to extend, and the guide rod is configured to drive the door of the refrigerator to rotate after the push rod pushes open the door of the refrigerator. By integrating the push rod and the guide rod in the mounting space inside the housing.

Abstract: Disclosed is a storage device. The storage device comprises a box body, at least one door body and an automatic door-opening assembly for opening the at least one door body. The automatic door-opening assembly comprises a housing and at least one automatic door-opening device. The housing is fixedly connected to the box body. Each automatic door-opening device is at least partially provided on a side, close to the box body, of the housing, and is fixedly connected to the housing, so as to fix the at least one automatic door-opening device. In the storage device of the present invention, the automatic door-opening device is first fixed to the housing to form an integrated assembly, and then the assembly is fixedly connected to the box body.

Abstract: An air-cooled refrigerator, comprising a bottom liner, an evaporator, a water receiving tray, and a heating wire. A cooling chamber located at the bottom of the bottom liner is defined inside the bottom liner, and the bottom wall of the bottom liner is provided with a water receiving tank with a water drainage outlet at its bottom; the evaporator is provided in the cooling chamber; the water receiving tray is provided between the evaporator and the bottom wall of the bottom liner to receive water on the evaporator, and a plurality of through holes are formed in a region of the water receiving tray facing towards the water receiving tank; the heating wire is coiled and provided between the water receiving tray and the evaporator to heat and defrost the evaporator, and the heating wire has an extension portion extending to the water receiving tank through the through holes.

Abstract: Provided is an air-cooled refrigerator with an evaporator at the bottom of a cabinet thereof. The air-cooled refrigerator comprises: a cabinet with a bottom liner; a partition cover plate transversely arranged in the bottom liner to divide the bottom liner into a storage space and a cooling chamber below the storage space; a return air cover arranged at the front of the cooling chamber and provided with at least one front return air inlet; and an evaporator, which is in a flat cuboid shape and is mounted in the cooling chamber in a manner of inclining upwards from front to back, where a front portion of a top surface of the evaporator, the partition cover plate and the return air cover define a frost-accommodating space, such that some of the air that enters from the front return air inlet enters the evaporator from the frost-accommodating space.

Abstract: A refrigerator (100) is provided. The refrigerator includes: a cabinet, in which are defined a cooling chamber (133) and at least one storage compartment; an evaporator (150), arranged in the cooling chamber (133) and configured to cool an airflow entering the cooling chamber (133) to form a cooled airflow; and an air blower (102), arranged on a transverse side of the evaporator (150), located upstream of the evaporator (150) in an airflow path, and configured to cause a return airflow in the at least one storage compartment to flow into the cooling chamber (133) to be cooled by the evaporator (150), and cause at least part of the cooled airflow to flow into the at least one storage compartment.

Abstract: A method for detecting whether an article with an abnormal temperature is placed in a refrigerator. The method includes: controlling a plurality of infrared sensors to collect temperature values after a door body is opened; determining whether an abnormal storage space in which the article with the abnormal temperature is possibly placed exists in a plurality of storage spaces; acquiring a first temperature change value of the abnormal storage space between time points before and after the article with the abnormal temperature is possibly placed in the abnormal storage space and a second temperature change value of the abnormal storage space caused by heat exchange between an external environment and the abnormal storage space between said time points; and determining whether the article with the abnormal temperature is placed in the abnormal storage space according to the first temperature change value and the second temperature change value.
