Abstract
The invention provides a high-capacity soft-package lithium manganese battery structure. The high-capacity soft-package lithium manganese battery structure comprises an aluminum-plastic composite film shell, a diaphragm (1), a negative pole piece (2) and a positive pole piece (3), and is characterized in that the diaphragm (1), the negative pole piece (2) and the positive pole piece (3) are positioned in the aluminum-plastic composite film shell; the diaphragm (1) is in a laminated structure; the negative pole piece (2) and the positive pole piece (3) are arranged sequentially between the laminated diaphragm (1); the thickness of the aluminum-plastic composite film shell is 0.15-0.200mm; the aluminum-plastic composite film shell is in a square structure. Due to the adoption of the high-capacity soft-package lithium manganese battery structure, the shortcomings that the small current output area due to a winded structure in an existing soft-package lithium manganese battery cannot meet the operating requirement of high current are overcome. Due to the adoption of the laminated structure, the current output area of the battery is increased, the high power requirements during use are met, and the capacity of the existing battery is increased from initial 1Ah to 10Ah.
Description
Technical field
The present invention relates to a kind of lithium/manganese dioxide battery field, more particularly it is a kind of large capacity lithium manganese flexible packaged battery pool structure.
Background technology
Lithium battery is the novel high-energy battery of successfully developing in 20th century.Lithium battery refers generally to lithium primary battery and lithium secondary battery.The negative pole of lithium primary battery is lithium metal, positive pole MnO
