The invention belongs to the technical field of batteries, and discloses a dual-ion battery and a preparation method thereof. The preparation method comprises the following steps: adding a polymer monomer in a burdening stage, uniformly dispersing the polymer monomer in a positive pole piece and a negative pole piece, finally injecting an electrolyte added with a polymer initiator, and initiating an in-situ polymerization reaction through high temperature, so that the liquid electrolyte is changed into a gel state. The invention also discloses the dual-ion battery prepared according to the method. The polymer monomers are uniformly distributed in the positive and negative pole pieces, so that the binding force of the active substance and the current collector is enhanced, and the pole piece expansion in the battery circulation process is reduced. In addition, the electrolyte is changed into a gel state, so that the oxidation potential of the electrolyte is remarkably improved, the stability of a positive and negative electrode interface is enhanced, the consumption of the electrolyte is reduced, and the safety performance of the battery is improved.

The utility model discloses a nitrogen gas purging device based on natural gas compressor unit relates to natural gas compressor technical field, including the nitrogen making system, pressure reducing valve, flowmeter, filler box, discharge pipeline that connect gradually, nitrogen making system is used to produce pure nitrogen, pressure reducing valve is used for adjusting pressure, flowmeter is used for real -time display nitrogen flow, and filler box is connected with pressure difference control valve, temperature transmitter and pressure transmitter, and temperature transmitter and pressure transmitter are used for monitoring the cavity pressure of filler box, and pressure difference control valve is used for real -time monitoring the cavity pressure of filler box and the pressure of discharge pipeline, and maintain the pressure of former is higher than the pressure of latter 0.05MPa 0.2MPa, and filler box still is connected with compressor crankcase and compression cylinder. The mode of constant differential pressure control can ensure that the sealing reliability under extreme working condition, and the nitrogen flow control is optimized, and the loss is reduced and the filler life is prolonged, adopts the modular design, simplifies the installation and maintenance process, and is suitable for old unit reconstruction.

The utility model relates to conveying device technical field especially relates to a textile conveying device for weaving, including track, the track is installed in the indoor top, the surface of track is provided with the slide seat of sliding, the lower end of slide seat is assembled and is provided with the link plate, the lower end of link plate is fixed with the air cylinder along both ends symmetry distribution, this scheme realizes the long distance transportation of transfer case through track and slide seat, effectively reduces the contact frequency of semi -finished product and personnel and other articles, compared with traditional cart, this device not only reduced the human consumption, also avoided the ground space occupation problem, can adapt to different site conditions, realizes linear efficient transfer, the suspension transport mode only contacts semi -finished product when loading and taking material, significantly improved the protective property of semi -finished product, reduces the pollution or damage risk due to the handling simultaneously, and the transfer case is equipped with the structure of the opposite -opening door and detachable seal strip, and the semi -finished product is conveniently and quickly loaded and unloaded and the closed nature in the transportation process is ensured.
