For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of lithium ion battery, its innovative point Be: include metal shell, polar cap, band, positive plate, negative plate, barrier film and electrolyte, described barrier film be arranged on positive plate and Between negative plate, described negative plate, barrier film, positive plate and electrolyte pass sequentially through the form of winding or lamination and assemble formation electricity Core, described battery core fixed placement is inside metal shell, and described positive plate is fixedly connected with polar cap by band, described negative Pole piece is fixedly connected with polar cap by band;
Described positive plate base material is banding aluminium foil, and active substance coats along aluminium foil horizontal maximum size, and active substance is along aluminum After paper tinsel longitudinal direction certain distance, leave certain distance aluminium foil and be not coated with the foil of active substance;
Described negative plate base material is banding aluminium foil, and active substance coats along aluminium foil horizontal maximum size, and active substance is along aluminum After paper tinsel longitudinal direction certain distance, leave certain distance aluminium foil and be not coated with the foil of active substance.
Further, described positive plate is welded by band or bonds, being riveted on polar cap, described band bonding or It is welded on positive plate and is not coated with on the foil of active substance.
Further, described negative plate is welded by band or bonds, being riveted on polar cap, described band bonding or It is welded on negative plate and is not coated with on the foil of active substance.
Further, described band selects sheet metal strip or radio frequency band.
The beneficial effects of the utility model are as follows: this utility model is by changing positive plate, negative plate and battery case , easily there is rosin joint when metallic aluminium foil thickness in monolayer is little and welds, thus has influence on battery in connected mode between both positive and negative polarity The index of internal resistance, thus have influence on the concordance of battery charging and discharging, by selecting novel conductive class material, novel conductive class material Material has adhesion strength height, conducts electricity very well, and operation controllability is strong, reduces the internal resistance of cell, by foil at width Bonding, between sheet metal strip or nonmetal band and metal shell, Joining Technology controllability is strong, it is ensured that outside pole piece is with metal Being reliably connected between shell, substantially increases battery with two side terminals, reduces the operation difficulty of battery assembling, produces controllability big Big raising.
