The invention belongs to the technical field of lithium ion batteries and particularly relates to a lithium ion battery and a making method thereof. The lithium ion battery comprises a battery cell, an electrolyte and a packaging shell containing the battery cell and the electrolyte. The battery cell comprises a battery positive plate, a battery negative plate and an isolation film arranged between the battery positive plate and the battery negative plate in a separation mode. A capacitor connected with the battery cell in parallel is further included in the packaging shell and comprises a capacitor positive plate and a capacitor negative plate, the capacitor positive plate is arranged on the outer surface of the battery cell and corresponds to the battery negative plate, and the capacitor negative plate is arranged on the outer surface of the battery cell and corresponds to the battery positive plate. When external puncturing or squeezing occurs, a short-circuiting loop is formed by the capacitor positive plate and the battery negative plate, a short-circuiting loop is formed by the capacitor negative plate and the battery positive plate, the charged battery is quickly discharged, the risk of fire catching or explosion of the battery is reduced, and the safety performance of the battery is improved. Besides, the capacitor can bear large-current charging and discharging, and thus the charging and discharging rate capability of the battery can be improved when the capacitor is connected with the battery cell in parallel.

The invention discloses a steam injection boiler adopting an emulsified coke slurry combustion device, which comprises a boiler body and an emulsified coke slurry combustion device. The smoke outlet on one end wall of the device. The emulsified coke slurry combustion device includes a shell surrounded by a front end wall, a rear end wall, and a side wall. A cylindrical combustion space is formed inside the shell. The front end wall is provided with At least one emulsified coke burner, and at least one oil burner and / or at least one gas burner, an outlet is opened on the rear end wall, and the outlet communicates with the furnace, wherein at least a part of the steam pipe in the furnace extends to the emulsified coke slurry In the side wall of the combustion device and adjacent to the inner surface of the side wall. In the present invention, the steam pipe is extended and arranged in the side wall of the combustion device, which effectively improves the dryness of the steam to 100%.

Provided is a preparation process of a composite heating plate for die casting. A heat preservation plate is arranged below the heating plate, the heat preservation plate and the heating plate are equal in length and width, and the height dimension of the heating plate is larger than that of the heat preservation plate. Round angles A are arranged at the four corners of the heat preservation plate, a plurality of columns of heat preservation holes are formed in the length direction of the heat preservation plate at equal intervals, and each column of heat preservation plates are formed in the width direction of the heat preservation plate. Round angles B are arranged at the four corners of the heating plate, and the round angles B and the round angles A are equal in diameter. The preparation process comprises the following operation steps of heating plate raw material mixing and stirring, heat preservation plate raw material mixing and stirring, heating plate forming, baking of two layers of composite plates, cooling and packaging.
