Abstract

The invention discloses a lithium battery material furnacing seggar which can effectively solve the problem in the prior art that a seggar has large structural force which easily causes crackles. The lithium battery material furnacing seggar comprises a bottom surface and lateral walls, the lateral walls and the bottom surface form a concave cavity for furnacing, the lateral walls feature circular arc transition, so do the lateral walls and the bottom surface. The invention has the advantages that: the product is easily formed, thus reducing the structural force and forming force of the seggar, crackles are not easily caused, thus lengthening service life of the seggar, reducing production cost and obviously improving product quality.

Description

technical field [0001] The invention relates to a sagger for roasting lithium battery materials. Background technique [0002] The existing lithium battery material roasting sagger is basically the sagger of ordinary fired products simply made into a shape change for lithium battery material roasting, such as the sagger used in the kiln for producing lithium ion battery cathode materials with application number 200620172461.8 Saggers, saggars with circular or nearly circular cross-sections, as well as known square saggars, have corner transitions between their surfaces. Such saggers have a large structural stress and are prone to cracks, which will affect their service life. , reduce product quality. Contents of the invention [0003] The object of the present invention is to provide a lithium battery material roasting sagger, which can effectively solve the problem of high structural stress and easy cracks in the prior art. [0004] In order to solve the above-mentioned...
