Beschreibung
Zusammenfassung:	The utility model discloses an encapsulation structure of a composite lithium battery, which comprises a shell, a positive pole, a negative pole, a positive plate, a negative plate, a positive current collector and a negative current collector, wherein the positive plate, the negative plate, the positive current collector and the negative current collector are positioned in the shell. The positive pole and the negative pole are arranged at both ends of the shell, the positive current collector is welded with the positive pole, and the negative current collector is welded with the negative pole. The two sides of the positive plate and the negative plate are provided with high-porosity polymer nanometer fiber battery diaphragms. The high-porosity polymer nanometer fiber battery diaphragms are formed by spraying polymer masking liquid mixed by polyacrylonitrile, polyvinylidene fluoride and polyvinylidene fluoride on two sides of the positive plate and the negative plate of the battery and then drying the liquid.
