Description
Technical field
This utility model relates to field of lithium, is specifically related to a kind of positive plate of lithium battery.
Background technology
The main composition material of lithium ion battery includes electrolyte, isolated material, positive and negative pole material etc..Positive electrode occupies larger proportion (mass ratio of positive and negative pole material is 3:1～41), because the performance of positive electrode directly affects the performance of lithium ion battery, its cost also directly determines battery cost height.
Existing positive plate of lithium battery easily weares and teares when using, and service life is not long, additionally, there may be resistance big, it is easy to the problems such as heating.

(2) technical scheme
For reaching above-mentioned purpose, this utility model provides a kind of positive plate of lithium battery, including lamellar body, described lamellar body is sequentially provided with nickel ion doped layer, articulamentum, graphite linings, articulamentum and nickel ion doped layer from top to bottom, described articulamentum is the aluminium paste bed of material, the described aluminium paste bed of material is mixed by aluminium powder and bonding agent, and the thickness of described articulamentum is less than 5 μm.
Further, described graphite linings is provided with multiple through hole.
Further, described nickel ion doped layer is provided with indent.
Further, the side of described lamellar body is provided with insulative glue.
Further, the thickness of described nickel ion doped layer is more than 1mm.
(3) beneficial effect
This utility model positive plate of lithium battery is novel in design, compact conformation, has long service life, the advantages such as resistance is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model positive plate of lithium battery；
Fig. 2 is the structural representation of nickel ion doped layer in this utility model positive plate of lithium battery.
Wherein, 1 is nickel ion doped layer, and 2 is articulamentum, and 3 is graphite linings, and 4 is indent.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
The structure of a kind of positive plate of lithium battery of the present utility model is as depicted in figs. 1 and 2, including lamellar body, described lamellar body is sequentially provided with nickel ion doped layer 1, articulamentum 2, graphite linings 3, articulamentum 2 and nickel ion doped layer 1 from top to bottom, described articulamentum 2 is the aluminium paste bed of material, the described aluminium paste bed of material is mixed by aluminium powder and bonding agent, and the thickness of described articulamentum 2 is less than 5 μm.
Different from traditional positive plate of lithium battery, the positive plate of lithium battery of this utility model design has good toughness, can effectively prolong and avoid 1 layer of powdered of nickel ion doped in use procedure, extend the service life of long positive plate of lithium battery.
In the present embodiment, described graphite linings 3 is provided with multiple through hole.
In the present embodiment, described nickel ion doped layer 1 is provided with indent 4.
In the present embodiment, the side of described lamellar body is provided with insulative glue.
In the present embodiment, the thickness of described nickel ion doped layer 1 is more than 1mm.
The beneficial effects of the utility model: novel in design, compact conformation, have long service life, the advantages such as production cost is low, and resistance is little.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
