The invention discloses a full-automatic electrolyte pressurizing impregnation device and method for an aluminum electrolytic capacitor. The device comprises am impregnation core bag pot, an electrolyte storage pot and a pressure pump, wherein the impregnation core bag pot and the electrolyte storage pot are connected with a secondary fluid pump through the pressure pump, the impregnation core bag pot is provided with a pressure gage, the upper end of the pressure pump is provided with a transducer, the upper end of the secondary fluid pump is provided with a pressure pump variable-frequency governor, the upper end of the pressure pump variable-frequency governor is provided with a controller, and the upper end of the controller is provided with an alarm lamp. When a capacitor core bag is impregnated, the method that self electrolyte is pressurized and permeated into the core bag is adopted. The device has small volume, saves occupied space, and lowers cost in equipment input and manufacture; and the method has the advantages of being low in impregnation temperature, more energy-saving and high in work efficiency, preventing impurities such as water and oil from polluting the electrolyte, and guaranteeing the electrical property stability and reliability of the aluminum electrolytic capacitor.

The invention discloses a SiOC ceramic material used for preparing the cathode of a lithium ion battery, a preparation method thereof and a lithium ion battery prepared from the ceramic material. The SiOC ceramic material comprises silicon, oxygen and carbon, and the mol ratio of silicon to oxygen to carbon is 1: alpha: beta, wherein, alpha is 0.4 to 0.2, beta is 0.4 to 5.0, and alpha plus beta is 0.8 to 7.0. The preparation method comprises the following steps: preparing organosilicon polymers with a molecular formula of a(R1R2SiO)x(R3R4SiO2)y(R5R6SiO3)zb, wherein, a and b are terminated functional groups, R1, R2, R3, R4, R5 and R6 are functional groups, at least one of which is hydrogen groups or alkenyl groups, x is 0.3 to 1, y is 0 to 0.7, z is 0 to 0.5, and x plus y plus z is 1; preparing organic small molecular compounds which comprise active groups that can react with hydrogen groups, silanol groups or alkenyl groups; mixing the organosilicon polymers with the organic small molecular compounds, preparing the two into a copolymer through crossing and curing, and carrying out pyrolysis so as to obtain the SiOC ceramic material. The lithium ion battery provided in the invention has the characteristics of high capacity, good cycle performance and high reversible capacity.
