This invention discloses a low-temperature high-performance cathode material, its preparation method, and its application, relating to the field of lithium-ion battery cathode material technology. The cathode material is a layered LiNi alloy. 0.6 Co 0.2 Mn 0.2 Using O2 as a matrix, a composite interface layer is constructed in situ on the particle surface. This composite interface layer comprises an outer continuous coating layer and an inner near-surface control layer. Surface reactions and heat treatment using a Li2O, B2O3, and Li3PO4 precursor system are employed to suppress interfacial side reactions, stabilize the near-surface structure, and achieve low-temperature Li... + Improved transport capacity. At -20°C, the preferred sample achieved a discharge specific capacity of 154.21 mAh g⁻¹ in the 10th cycle. ‑1 The rate performance, cycle stability and polarization index are all superior to the original sample and the key control group.

This utility model relates to the field of electric curtain technology, specifically to an electric curtain guide rail, including a guide rail body, multiple mounting mechanisms, multiple recessed plates, and multiple connecting plates. The interior of the guide rail body has a corrugated texture. In use, a slider is placed inside the guide rail body and fixed in place by the multiple connecting plates. The added recessed plates make it easier and tighter to assemble the guide rail body, solving the problem of guide rail jamming and excessive noise caused by improper assembly after transporting in sections. The innovative symmetrical design of the guide rail body allows the motor to be installed vertically or upside down, meeting personalized installation needs. Furthermore, the corrugated texture inside the guide rail body reduces the contact area between the transmission belt and the guide rail body during sliding, reducing friction and noise.

The utility model relates to a split mounting type highway bridge construction site protective fence which comprises a plurality of stand columns, the height of each stand column is 1-1.2 m, a protective fence body is arranged between every two adjacent stand columns, a plurality of idler wheels are arranged on the bottom wall of each protective fence body, a plurality of connecting blocks are arranged on the stand columns, and the connecting blocks are connected with the stand columns. The connecting blocks are arranged in the height direction of the stand column, the protective fence is provided with plug pins connected with the connecting blocks, and the connecting blocks are provided with positioning pieces for locking the plug pins. The bolt is inserted into the inserting groove, the positioning piece is used for locking the bolt, a bolt connection mode is replaced, and the installation convenience can be improved.

The utility model discloses a kind of multifunctional ecological revetment blocks for river regulation, belong to the technical field of hydraulic engineering construction, the block includes block body and wedge, block body four side surface structures are same, are equipped with tenon, mortise and half hole, when arbitrary two side surfaces are spliced, tenon is embedded mortise, vertical wedge hole is formed in its half hole alignment, when construction, first assemble block to form revetment level, then the conical frustum wedge of same material is driven into wedge hole, wedge uses its wedge effect to generate huge radial pressure, adjacent block is locked transversely, while its lower end is deeply into foundation, provide vertical anchoring force, the utility model realizes the " transverse locking, vertical anchoring " of revetment structure, integrality, stability and anti-collapse ability are very strong, and construction is convenient, ecological friendly, with very high popularization value.

The utility model discloses a quick connecting device of robot protective clothing, and relates to the technical field of protective clothing, the quick connecting device comprises a connecting ring, the front side and the back side of the connecting ring are both provided with sliding grooves, a plurality of sliding blocks are arranged in the sliding grooves, the center of each sliding block is provided with a mounting groove towards one side, and the protective clothing is inserted into the mounting groove; the sliding blocks are installed at the two ends of the protective clothing for clamping, the corresponding sliding blocks are embedded in the connecting rings, the two ends of the connecting rings are sleeved with the protective clothing to connect the two protective clothing sections, the number of the protective clothing and the number of the connecting rings can be selected according to requirements, and therefore the length of the protective clothing can be customized to adapt to robots of different heights.

The utility model discloses a modularized gas deodorization device which is characterized by comprising a mounting frame, the mounting frame is in a hollow ring shape, at least one deodorization medium box is arranged in the mounting frame in a sliding mode, the top side and the tail side of the deodorization medium box are open, a deodorization medium is arranged in the deodorization medium box, and the deodorization medium box is provided with a gas inlet and a gas outlet. The deodorization medium is used for filtering peculiar smell molecules in gas, an air inlet channel is formed between the deodorization medium box and the inner wall of the top of the mounting frame, and the gas enters the deodorization medium box through the air inlet channel and flows out from the tail side of the deodorization medium box. Compared with the prior art, the gas deodorization device has the advantages that the expansion cost is lower, the splicing is simple, the use flexibility of the gas deodorization device can be effectively improved, and the use cost is reduced.
