摘要： A battery pack relating to the field of batteries includes a battery module, a coolant and a battery box. The battery module and the coolant are disposed in the battery box. The battery module is at least partially immersed in the coolant. A sealing layer containing a barrier liquid is covered on the coolant. The heat generated by the battery cell which occurs thermal runaway is taken away rapidly by using the vaporization latent heat of the coolant, to thereby avoid heat accumulation and prevent propagation of thermal runaway among battery cells, thereby protecting the safety of the battery pack.

摘要： The present invention relates to a preparation method of ionic liquids, particularly to a one-step reaction method used for synthesizing quaternary ammonium compounds or quaternary phosphonium compounds. In the method, a nitrogenous or phosphorous compound, a proton compound, and a carbonate ester are added into a reactor simultaneously to synthesize corresponding the quaternary ammonium ionic liquid or the quaternary phosphonium ionic liquid through said one-step reaction, i.e., ‘one-pot method’ reaction, during which three reactants are involved. The present invention also provides a lithium ion secondary battery comprising the ionic liquid prepared by above-mentioned preparation method. The ionic liquid preparation method of the present invention can widen the choice range of raw materials needed when preparing ionic liquids, and further widen the synthesized ionic liquid species.

摘要： The present invention provides a method for preparing an aromatic polyamide porous membrane and an aromatic polyamide porous membrane prepared by the above method. The method for preparing an aromatic polyamide porous membrane includes the following steps: mixing an ionic liquid with an aromatic polyamide into a solvent to form a mixed solution; the mixed solution forming a membrane in a coagulation bath; and extracting with an extractant to remove the solvent and the ionic liquid from the membrane to yield a porous membrane. In the method of the present invention, the application of the ionic liquid would greatly reduce the application of additives; further, the ionic liquid has a high stability and is easy to be separated from other solvents and be recycled, which assures the safety during the usage and recycle thereof.

摘要： A battery pack system and a liquid leakage detection method thereof are provided. The battery pack system comprises battery cells, a isolated liquid and a battery box containing the isolated liquid. The battery cells are soaked in the isolated liquid. The battery box is formed with a isolated liquid outlet and a isolated liquid inlet. The outlet is connected together with the inlet via a circulation pump and a liquid separation device to form a circulation passage. When electrolyte leakage occurs to any of the battery cells, the electrolyte is separated into the liquid separation device and detected by a detection component. The present disclosure encloses the leaked electrolyte into the fire-retardant isolated liquid to prevent the electrolyte from contacting with the air so as to improve the safety of the battery box body.
