Utility model content
For above-mentioned technical problem, the utility model, which provides one kind, will not occur malposition of electrode and cause micro-short circuit
And puncture a Soft Roll lithium-manganese cell of phenomenon.
In order to solve the above-mentioned technical problem, concrete scheme provided by the utility model is as follows：A kind of Soft Roll lithium manganese electricity
Pond, including positive plate and negative plate, are painted with membrane layer between the positive plate and negative plate, the positive plate includes stainless steel
Layers of foil and the carburization zone and coating layer being coated on successively in stainless steel layers of foil.
Preferably, the positive plate is rectangle structure, and a Side Cutting is jagged, and the non-notch position of the side is welded for cathode
Disk, i.e., without extra soldered lug, reduce production cost.
Preferably, the negative plate is rectangle structure, and a Side Cutting is jagged, and the non-notch position of the side is welded for anode
Disk, i.e., without extra soldered lug, reduce production cost.
Preferably, the length of the positive terminal pad is more than the length of negative terminal pad.
Preferably, the negative plate includes the FPC layers of copper plate being also successively set on FPC layers and lithium belt.
Compared with prior art, the beneficial effects of the utility model are：Soft Roll lithium manganese provided by the utility model
Battery design is reasonable, it is simple to make, and easily realizes automated production, and thickness is less than 0 .40mm, has flexibility well and stablizes
Property, battery will not occur malposition of electrode in flexural deformation and cause micro-short circuit.

Embodiment
In order to make those skilled in the art be better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings to this
The technical solution of utility model is further elaborated.
As shown in Fig. 1 ~ 3, an a kind of Soft Roll lithium-manganese cell, including positive plate and negative plate, the positive plate and anode
Be painted with membrane layer between piece, the positive plate include stainless steel layers of foil and the carburization zone being coated on successively in stainless steel layers of foil with
Coating layer, wherein, the main material of carburization zone is carbon, and the main material of coating layer is manganese dioxide.
Positive plate in the present embodiment is rectangle structure, and a Side Cutting is jagged, and the non-notch position of the side is cathode
Pad, negative plate are rectangle structure, and a Side Cutting is jagged, and the non-notch position of the side is negative terminal pad, i.e., without extra
Soldering polar ear, reduces production cost.
Wherein, the length of positive terminal pad is more than the length of negative terminal pad, and negative plate is also successively set on FPC including FPC layers
Copper plate and lithium belt on layer.
Technical solution provided by the utility model is equally applicable to cake type Soft Roll lithium primary battery.
Finally, it should be noted that above example is only illustrating the technical solution of the utility model rather than to this reality
With the limitation of novel protected scope, any modification made where within the spirit and principles of the present invention, equivalent substitution and
Improve etc., it should be included within the scope of protection of this utility model.
