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： The present disclosure provides a liquid membrane conveying apparatus for preparing a porous membrane includes a transmission unit and a carrier unit. The carrier unit conveys a liquid membrane into a gelling solution by the entrainment of the transmission unit. The carrier unit includes a first carrier and a second carrier. The first carrier and the second carrier respectively contact with opposite edges of the liquid membrane along a conveying direction of the liquid membrane. The consistency of the pores on the two surfaces of the porous membrane is improved by using the liquid membrane conveying apparatus.

摘要： A battery pack includes a plurality of electrically connected battery modules. The battery module includes a plurality of type-A battery cells and a plurality of type-B battery cells. The type-A battery cells and the type-B battery cells are arranged in alternate manner. Both of the type-A and the type-B battery cells have a positive tab and a negative tab. The positive tabs and negative tabs of all type-A battery cells are electrically connected with a type-A first and a type-A second connecting pieces respectively. The positive tabs and negative tabs of all type-B battery cells are electrically connected with a type-B first and a type-B second connecting pieces respectively. When the battery pack burns, the type-A battery cells have an isolation effect on stopping the diffusion of combustion so as to improve the safety, and also improve the rapid charging and discharging ability and energy density of the battery pack.
