Description
Technical field
The utility model relates to battery manufacturing field, is specifically related to a kind of Novel nickel-hydrogen battery.
Background technology
Ni-MH battery (NiMH) is improved by nickel-cadmium cell (NiCd), replaces cadmium (Cd) with the metal that can absorb hydrogen.It provides the capacitance higher than nickel-cadmium cell with identical price, does not substantially have memory effect, is a kind of battery of environmental protection.Ni-MH battery has that energy density is high, charge/discharge rates is fast, lightweight, the advantage such as life-span length, non-environmental-pollution, has become the new forms of energy product of countries in the world competitively Study and Development.Since the nineties in last century, successively enter the industrialization stage at home and abroad, and be mainly used in consumer electronics field, and in the majority with A type, AA type, be used for greatly notebook computer, video camera, pocket telephone etc.
And existing Ni-MH battery, its battery core adopts the non-woven cloth of polypropylene using Ni-MH battery at present, and because of the problem of mechanical strength, its thickness must on 0.1mm, and generally common is about 0.12-0.13mm, compares lithium rechargeable battery film used thick a lot.Film thickness, though can be thinning via fibre density decline, its mechanical strength also can and then decline, cause membrane ruptures, cause short circuit, affect the useful life of battery, and its battery core positive plate is directly connected with battery cap, its energy conversion rate is low, causes the loss when discharging of large energy.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of rational in infrastructure, long service life, the Novel nickel-hydrogen battery that energy utilization rate is high.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of Novel nickel-hydrogen battery, it battery core and the electrolyte that comprise housing, battery cap and be positioned at housing, described battery core comprises the pillared barrier film of a winding, and be located at this respectively and be wound into the upper end of barrier film after column and the positive plate of lower end and negative plate, wherein, described barrier film comprises polyethylene film layer and Teflon membranes, and mutually superposes coiling and molding successively, and Teflon membranes is located at inside polyethylene film layer; Described positive plate base material is coated with the polytetrafluoroethylene reticular membrane that thickness is 4 ~ 5 μm, and described positive pole, by a conducting strip, is connected with described battery cap.
Described conducting strip is discoid, and center is provided with projection, and described positive plate one end is welded on this conducting strip lower surface, and described projection is connected with described battery cap.
Also steam vent is provided with at described high spot.
It also comprises a Foamed Nickel, and described Foamed Nickel cushioning is in the bottom of described battery case, and the bottom of described battery core is connected with the bottom of described battery case by described Foamed Nickel.
