The application discloses a programmable drug release anti-infection and bone formation promoting multifunctional orthopedic internal implant device and a preparation method thereof. The implant is prepared according to the following steps: 1) introducing a titanium nanotube (TNT) structure on the surface of a titanium alloy base by using an anodic oxidation method; 2) sequentially loading an anti-infection component, a bone formation promoting factor and a blood vessel formation promoting factor into the TNT tube by using a vacuum sequential loading process; and 3) finally, coating a poly-tannic acid (PTA) coating on the surface of the material base by using a tannic acid (TA) in-situ self-polymerization technology. The multifunctional bone implant device can sequentially release the anti-infection drug, the blood vessel formation promoting factor and the bone formation promoting factor in the order of the vacuum drug loading, and the modified surface of the device has good drug release and oxidation resistance, so that the bone infection can be efficiently prevented and treated, and the bone repair efficiency is improved.

The invention relates to a lithium ion battery in the technical field of lithium batteries, in particular to a solid-state lithium ion battery. A double-layer electrode structure is adopted to achieve the synergistic effect of lithium-rich manganese and lithium manganate, the double-layer positive electrode active material layer is arranged in the positive electrode, the thickness ratio and the mass ratio of the second positive electrode active material layer to the first positive electrode active material layer are controlled, and meanwhile, the lithium supplementing material is added into the positive electrode, so that the lithium-rich manganese-lithium battery is obtained. And the rate capability and the electrochemical stability of the battery are improved. Specifically, the positive electrode includes a positive electrode current collector, a first positive electrode active material layer including spinel manganese oxide, and a second positive electrode active material layer including lithium manganese oxide of a layered structure and a third positive electrode active material. Through the design, the performance of the lithium battery is remarkably improved, the structural stability is enhanced, and the cycle life of the lithium battery is prolonged.
