Abstract
A nano power lithium battery shell relates to the technical field of lithium batteries and comprises the hollow square shell. An upper cover plate is fixedly connected to the upper portion of the shell. A pole column hole and a liquid filling hole are arranged on the upper cover plate. The nano power lithium battery shell is characterized in that the shell is in a plastic structure. At least one layer of nano material protective layer is arranged on the outer surface of the shell. The nano power lithium battery shell is good in toughness and remarkably better than a metal shell under impact of outer force, and cannot enable a negative pole and a positive pole of a battery core to be shorted out under the condition of bumping, striking and puncturing. The nano material protective layer can prevent air and moisture from permeating in a battery, thereby greatly prolonging service life of the battery.
Description
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to a kind of nanometer dynamic lithium battery shell.
Background technology
Along with new forms of energy development in recent years, emerge a lot of power lithium-ion battery technology both at home and abroad.Traditional battery case has box hat, aluminum hull, aluminum plastic film Soft Roll, the common shell etc. of moulding, and they all have pluses and minuses separately separately, and is heavy such as the box hat quality; Welding procedure is complicated, runs into external force deformation and is difficult to recover, and aluminum hull also is same defective to be arranged but quality is low weight; And the easy damaged leakage of aluminum plastic film Soft Roll; When jolting bump, damage battery easily, thereby battery can not get ensureing the common shell easy ageing of moulding useful life; Material air tightness through modification is poor, is difficult to reach the standard in useful life of electrokinetic cell 8-10.
The utility model content
The utility model technical problem to be solved is to provide a kind of safe, and air-tightness is good, the nanometer dynamic lithium battery shell of long service life.
The utility model technical problem to be solved adopts following technical scheme to realize,
A kind of nanometer dynamic lithium battery shell comprises the square shell of hollow, and said shell upper is fixed with upper cover plate; Said upper cover plate is provided with pole hole and liquid injection hole; It is characterized in that: said shell is a plastic construction, and the outer surface of said shell is provided with one deck nano material protective layer at least, so just forms the top layer of similar chromium plating in case surface; Its density is high, has the function that obstruct air and moisture content are penetrated into the inside of battery.
Said liquid injection hole raises up, and is provided with screw thread in the said liquid injection hole.
Described pole hole caves inward.
The beneficial effect of the utility model is: the utility model good toughness; Under the impact of external force, obviously be better than metal-back; Can not make the positive and negative short circuit of electric core jolting, clash into, puncture; The nano material protective layer has and intercepts the function that air and moisture content are penetrated into the inside of battery, has prolonged battery life greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model profile.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1, shown in Figure 2, a kind of nanometer dynamic lithium battery shell comprises the square shell 1 of hollow, and shell 1 top is fixed with upper cover plate 2; Upper cover plate 2 is provided with pole hole 4 and liquid injection hole 3, and shell 1 is a plastic construction, and the outer surface of shell 1 is provided with one deck nano material protective layer 5; So just form the top layer of similar chromium plating on shell 1 surface, its density is high, has the function that obstruct air and moisture content are penetrated into the inside of battery; Liquid injection hole 3 raises up, and is provided with screw thread in the liquid injection hole 3, and pole hole 4 caves inward.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
