    Abstract: The present disclosure provides a separator and an electrochemical device, the separator is provided with a folded structure unit across a widthwise direction of the separator, and an overlapping part of the folded structure unit is filled with an adhesive. When the separator is applied into a production of the electrochemical device, a winding process can be performed as usual. After an electrolyte injection or high temperature aging of the electrochemical device, the adhesive filled in the folded structure unit of the separator may be dissolved into the electrolyte, the folded structure unit can be unfolded to a flat position again, so as to effectively eliminate deformation of the electrochemical device, which may be caused by thermal contraction of the separator, over stress in the separator wound in a cell, or the separator's binding on expansion of negative and positive electrodes, during operation and production of the electrochemical device.

    Abstract: A lithium battery module includes a sealed housing, a fixture and at least one soft-shell capacitor assembly. A one-way exhaust structure is disposed on the sealed housing. The fixture is accommodated in the sealed housing. The at least one soft-shell capacitor assembly is disposed on the fixture. The soft-shell capacitor assembly is pressed and fixed by the fixture while a vent is formed on the soft-shell capacitor assembly. Thereby, the sealed housing and the one-way exhaust structure are capable of isolating the environment and controlling the pressure relief and exhaust.

    Abstract: This invention provides a negative electrode active material for lithium ion capacitor, which reduces the thickness of a negative-electrode active material layer while maintaining the conventional level of energy density.The negative-electrode active material for a lithium ion capacitor is a composite carbon material manufactured by kneading a carbon black having an average particle diameter of 12 to 300 nm measured by the electron microscopy method with a carbon precursor such as pitch, the resulting mixture is baked or graphitized baking between 800° C. to 3200° C., and then pulverized such that the average particle diameter (D50) thereof is 1 to 20 μm and the BET specific surface area is between 100-350 m2/g. An initial charging capacity is at least 700 mAh/g, and the cell volume is reduced as the thickness of the negative electrode active material layer becomes thinner than the conventional one.
