Abstract
The utility model provides a cylindrical high power capacity lithium cell positive plate structure, includes the positive plate, and the middle part along its length direction on the positive plate is equipped with anodal utmost point ear position, and anodal utmost point ear position is inside sunken recess, and the recess sets up along the width direction of positive plate, and the recess in -connection has anodal utmost point ear. The length of anodal utmost point ear position place recess is 13 to 12 of positive plate width. Two sides of positive plate are all inwards sunken to set up anodal utmost point ear position, anodal utmost point ear lower part etc. Is divided into a plurality of clamping pieces, and the clamping piece strides across the positive plate and lies in the positive plate both sides. The quantity of clamping piece is 3. The utility model discloses a positive plate and anodal utmost point ear, the positive plate shape is the rectangle, and the position department that connects anodal utmost point ear on the positive plate reserves out subregion (anodal utmost point ear position promptly) and the welding of anodal utmost point ear, and all the other regions are covered by the powder. Compare with traditional lithium cell, this structure can effectively increase the coverage area of anodal powder, improves the capacity of battery.
Description
Technical field
The utility model relates to the combination of a kind of battery pole piece and lug, particularly relates to a kind of cylindrical high-capacity lithium battery positive plate structure.
Background technology
Along with the develop rapidly of digital product, communication, illuminating industry, the requirement of lithium battery is also become more and more higher, gradually towards high power capacity, high-octane future development.In order to adapt to the demand of these products, in the urgent need to developing high power capacity, high-energy type lithium battery.
The positive plate structure of tradition lithium battery substantially adopts and reserves the lug position consistent with positive plate width and weld with positive pole ear, lug position is arranged along the whole width of positive plate, region, whole lug position does not apply powder, therefore this structure can reduce the area coverage of positive mix to a certain extent, reduces the capacity of battery.
Summary of the invention
The purpose of this utility model is to provide a kind of cylindrical high-capacity lithium battery positive plate that can improve battery capacity.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cylindrical high-capacity lithium battery positive plate structure, comprises positive plate, it is characterized in that, on positive plate, middle part is along its length provided with positive pole ear position, the groove of positive pole ear position for caving inward, groove is arranged along the Width of positive plate, is connected with positive pole ear in groove.
According to described one cylindrical high-capacity lithium battery positive plate structure, it is characterized in that, the length of place, described positive pole ear position groove is 1/3 to 1/2 of described positive plate width.
According to described one cylindrical high-capacity lithium battery positive plate structure, it is characterized in that, what two sides of described positive plate all caved inward arranges described positive pole ear position; Described positive pole ear bottom is divided into multiple intermediate plate, and intermediate plate strides across positive plate and is positioned at positive plate both sides.
According to described one cylindrical high-capacity lithium battery positive plate structure, it is characterized in that, the quantity of described intermediate plate is 3.
The utility model comprises positive plate and positive pole ear, and positive plate shape is rectangle, and position positive plate connecting positive pole ear reserves subregion (i.e. positive pole ear position) and welds with positive pole ear, and all the other regions are covered by powder.Compared with traditional lithium battery, this structure effectively can increase the area coverage of positive mix, improves the capacity of battery.
