Embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model lithium battery is described in further detail.
For convenience of description, present embodiment is that circular stacked lithium/manganese dioxide battery is that example describes with profile.
As depicted in figs. 1 and 2, lithium battery 100 comprises circular housing and the electric core that is positioned at circular housing.Housing mainly comprises ring body 10 and the lid 20 that welds together, and the vacation of the annular that is connected with lid 20 lid 30.Lid 20 be provided with 20 insulation of a plurality of and lid is connected, with the electrode column 21 of false lid 30 and the electric connection of electric core.The electricity core mainly comprises the electrolyte (not shown), and the negative pole lithium sheet 40 that is successively set on the annular in the body 10 from the bottom to top, barrier film 50, positive pole 60, collecting ring 70 and insulating trip 80.
Housing and collecting ring 70 all do not adopt and make with the metal material of electrolyte generation chemical reaction, can be metal or alloy such as stainless steel, carbon steel, and in the present embodiment, housing and collecting ring 70 adopt stainless steel to make.Barrier film 50 and insulating trip 80 adopt insulating material, can be glass fibre or poly tetrafluoroethylene.Anodal 60 mainly comprise manganese dioxide, conductive agent and binding agent etc.Among other embodiment, anodal 60 material with carbon elements that can mainly comprise as carrier.
Concrete, ring body 10 cross section radially is dual U-shaped substantially.Be formed with step on ring body 10 inwalls, be used to support lid 20 and help lid 20 location.Lid 20 tops are formed with the annular groove that runs through lid 20, offer a plurality of through holes on the groove symmetrically.Electrode column 21 is by insulating material, and for example glass insulator is fixed in the through hole.A plurality of electrode columns are set make battery discharge even,, also an electrode column can only be set according to concrete condition.
Negative pole lithium sheet 40 is close to body 10 bottoms.Barrier film 50 cross section radially is dual U-shaped substantially, is used to accommodate positive pole 60, collecting ring 70 and insulating trip 80, and barrier film and insulating trip are with electrical isolation anodal 60 and negative pole 40 and positive pole 60 and body 10.Collecting ring 70 cross section radially is two inverted U font (see figure 3)s substantially, is set on anodal 60, is used to increase the cell reaction area and anodal 60 dilatancy directions are limited in direction perpendicular to lid 20.Insulating trip 80 is positioned at collecting ring 70 tops, and the position of its counter electrode post 21 offers through hole.Electrode column 21 passes this through hole and collecting ring 70 directly or by the flexible metal tape welding is connected together.
