Abstract

The invention provides a sintering device used for sintering lithium phosphate, which comprises a feeding reactor. The feed reactor comprises a horizontally fixed feeder shell and a pushing screw rod arranged in the feeder shell, wherein both ends of the feeder shell are respectively provided with a feeding hole and a discharge hole; the sintering device also comprises a sintering kiln body sleeved outside the feeder shell; the feeding hole and the discharge hole are respectively arranged at the outer sides of both ends of the sintering kiln body; a first cooling device is arranged between the feeding hole and the sintering kiln body; and a second cooling device is arranged between the discharge hole and the sintering kiln body; and the sintering device also comprises a driving device fordriving the pushing screw rod to rotate and a gas protecting device connected with the feeding reactor.

Description

technical field [0001] The invention relates to a sintering device, in particular to a sintering device for sintering lithium iron phosphate. Background technique [0002] LiCoO as cathode material for commercial Li-ion batteries 2 Mainly, the material has reliable performance and long cycle life, but due to the relative lack of cobalt resources, the cost of the material is too high; moreover, cobalt has certain toxicity, and there are unsafe factors when the battery is abused. Therefore, people have been working hard to find alternatives to LiCoO 2 s material. Among various materials that may replace lithium cobalt oxide, lithium iron phosphate is one of the current research hotspots. Whether it is from the perspective of resources, environment or performance, lithium iron phosphate is considered to be an alternative to LiCoO 2 the most ideal material. [0003] In the prior art, the synthesis methods of lithium iron phosphate mainly include solid-phase synthesis, hydro...
