Composite ceramic membrane for lithium ion batteries and preparation method thereof
ActiveCN103956451AAvoid thermal runawayImprove high temperature thermal stabilityCell component detailsElectrolytic agentCeramic coating
The invention discloses a composite ceramic membrane for lithium ion batteries and a preparation method thereof, including a ceramic coating modification method and a ceramic lithium battery membrane. The ceramic protective layer is mainly prepared from a ceramic-adhesive mixture subjected to graft modification by a sodium-sulfonate / sodium-carboxylate-group-containing anionic surfactant. The grafting is completed by using a grafting-on process under the action of a coupling agent; the grafting ratio of the ceramic is higher; the high-temperature-resistant large-surface-area nano ceramic is introduced to the conventional PP (polypropylene) membrane surface, the insulativity and electrolyte wettability of the modified ceramic membrane are greatly enhanced; and the membrane has excellent high-temperature heat stability especially at the high temperature of 130 DEG C, 150 DEG C and 180 DEG C. The lithium battery composite membrane avoids the thermal shrinkage of the convention membrane, thereby avoids the thermorunaway in the battery due to thermal shrinkage, and further enhancing the safe reliability of the lithium ion battery.

Large-area TiB-TiC reinforced titanium-based composite coating and preparation method thereof
The invention discloses a large-area TiB-TiC reinforced titanium-based composite coating prepared from the following components in percentage by weight: 83-88 percent of Ti, 5-7 percent of B4C, 2-4 percent of Al, 1-3 percent of nano TiC and 3-5 percent of rare-earth oxide. The invention adopts a new method for preparing a pre-coating layer which has the advantages of smooth surface, controllable thickness, less adhesive and relatively simple process. In addition, the invention optimally selects the proportioning of a cladding material system so that the coating after cladding has reinforcing phases of TiB and TiC; in addition, since a base body and a base body material Ti6Al4V are both titanium alloy, the coating and the base body have favorable physical compatibility. The invention also remarkably lowers the intensity degree of reaction for generating TiB and TiC by adding a little amount of thinner nanoTiC.
