Diaphragm and battery with same

The utility model discloses a diaphragm and a battery with the same. The diaphragm of the battery comprises a diaphragm body, an inorganic material layer and a bonding layer, wherein the inorganic material layer and the bonding layer are arranged on two opposite surfaces of the diaphragm body, respectively. According to the diaphragm of the battery disclosed by the utility model, the inorganic material layer is arranged on one surface of the diaphragm body, and the diaphragm contacts a negative electrode plate in the battery by virtue of the inorganic material layer, and therefore, the safety performance of the battery is effectively improved; the bonding layer is arranged on the other opposite surface of the diaphragm body, and the diaphragm contacts a positive electrode plate in the battery by virtue of the bonding layer, so that a battery deformation problem is effectively solved, and the volume ratio capacity of the battery is improved.
