Abstract: A sealing assembly for a battery, a method of preparing the sealing assembly and a lithium ion battery are provided. The sealing assembly for a battery comprises: a ceramic ring (3) having a receiving hole (31), a metal ring (4) fitted over the ceramic ring (3) for sealing an open end of the battery, and a column (2) formed in the receiving hole (31) which comprises a metal-metal composite (21), wherein the metal-metal composite (21) comprises: a metal porous body, and a metal material filled in pores of the metal porous body.

Abstract: A sealing assembly, a method of preparing the sealing assembly and a battery are provided. The sealing assembly comprises a metal ring having a mounting hole therein; a ceramic ring having a connecting hole therein and disposed in the mounting hole; and a core column disposed in the connecting hole, wherein at least one of an inner circumferential wall surface of the metal ring, an outer circumferential wall surface of the ceramic ring, an inner circumferential wall surface of the ceramic ring and an outer circumferential wall surface of the core column is configured as an inclined surface, and an inclination angle of the inclined surface relative to a vertical plane is about 1 degree to about 45 degrees.

Abstract: An electric heater, and an apparatus, a heating and air conditioning system and a vehicle, each comprising the electric heater, are provided. The electric heater comprises an outer frame; a heating core configured to connect to a power source and disposed within the outer frame; and a sealing-waterproof glue member disposed within the outer frame and configured to encase at least one end of the heating core. The heating core further comprises: a plurality of heat dissipating components and heating components arranged alternately, and each of the heat dissipating component is coupled with a heating component via a thermal conductor. Each of the heating components further comprises a core tube and a positive temperature coefficient thermistor disposed in the core tube.

Abstract: A method for metallizing a surface of a ceramic substrate includes molding and sintering a ceramic composition to obtain the ceramic substrate, in which the ceramic composition comprises a ceramic powder and a functional powder dispersed in the ceramic powder, radiating a predetermined region of the surface of the ceramic substrate, and performing chemical plating on the ceramic substrate.
