Description
Technical field
The utility model belongs to the battery technology field, is specifically related to a kind of lithium button cell.
Background technology
Characteristics such as the lithium button cell is strong because of its voltage adaptation, self-discharge rate is low, volume is little are widely used in the little and thin electronic product of some volumes, as ultra-thin remote control device, calculator, electronic dictionary, bluetooth earphone, MP3, IC-card, wrist-watch etc.In addition, again owing to advantages such as its serviceability temperature scope is wide, good seal performance, period of storage length, discharging voltage balance are usually used in the reserve memory power supply of some products (as the clock power of computer main board).Along with development of modern science and technology, pocket, portable electronics get more and more, and when some emerging electrical equipment are more and more higher to lithium button cell performance requirement, also require the cost of lithium button cell more and more lower, to satisfy the market of continuous development and change.
No matter lithium button cell on the conventional art is positive battery shell and negative battery shell, and its material generally adopts stainless steel material, and this also is the reason that lithium button cell cost can't decline to a great extent.
The utility model content
The utility model purpose is to overcome the prior art deficiency, and a kind of novel lithium button cell is provided, and this button cell corrosion resistance and good and cost are lower, have also kept lithium button cell excellent electrochemical properties simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
A kind of lithium button cell comprises positive battery shell and negative battery shell, and wherein, the inside and outside surface of described positive battery shell is equipped with nickel coating.
The inside and outside surface of described negative battery shell is equipped with nickel coating; The nickel coating metallized aluminum of positive battery shell inner surface and/or titanium composite bed.
Concrete, the material of described positive battery shell and negative battery shell can be the ordinary steel material, and thickness is between the 50-1000 micron.
The nickel coating thickness on the inside and outside surface of described negative battery shell is between the 0.001-50 micron.
The nickel coating thickness on the inside and outside surface of described positive battery shell is between the 0.001-50 micron, and the aluminium that positive battery shell inner surface nickel coating coats and/or titanium composite bed thickness are between the 0.001-500 micron.
Described lithium button cell also contains plus plate current-collecting body, positive pole, barrier film, sealing ring and negative pole, described positive battery shell and negative battery shell interlock and set gradually plus plate current-collecting body, positive pole, barrier film and negative pole from top to bottom in the cavity that forms, and are sealed into enclosure space by the sealing ring insulation and with described cavity between positive battery shell and the negative battery shell.
The utility model is by arranging nickel coating on the inside and outside surface of negative battery shell, and positive battery shell surfaces externally and internally arranges nickel coating, and the nickel coating metallized aluminum of positive battery shell inner surface and/or titanium composite bed have improved the decay resistance of battery case.In addition, the both positive and negative polarity battery case is selected ordinary steel material (total nickel content is lower than 5%) for use, has not only reduced the production cost of battery significantly, has also kept lithium button cell excellent electrochemical properties, and is practical, is worthy of popularization.
