Description
Technical field
The utility model relates to a kind of novel negative pole piece structure of new type lithium ion battery.
Background technology
The negative plate of existing lithium ion battery, generally only have a flow collection sheet, therefore, catchment effect is not ideal enough, therefore, is necessary the novel negative pole piece structure designing a kind of novel new type lithium ion battery.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel negative pole piece structure of new type lithium ion battery, and the novel negative pole piece structure of this new type lithium ion battery has novel structure and the good advantage of catchment effect.
The technical solution of utility model is as follows:
A novel negative pole piece structure for new type lithium ion battery, comprises lithium sheet (3), currect collecting net (2) and flow collection sheet; Currect collecting net and lithium sheet are crimped together, and flow collection sheet is arranged on outside currect collecting net, and by rivet, flow collection sheet, currect collecting net and lithium sheet are riveted into an entirety;
Described flow collection sheet comprises main flow collection sheet (1) and multi-disc Bifurcation Set flow (4);
Main flow collection sheet is L shape flow collection sheet; Bifurcation Set flow is bar shaped flow collection sheet; One end of multi-disc Bifurcation Set flow is all connected with L shape flow collection sheet; And the flow of multi-disc Bifurcation Set is equidistantly arranged.
Described Bifurcation Set flow is 4.
Flow collection sheet is provided with multiple riveted holes (5).
Flow collection sheet is nickel strap, nickel strap has equally distributed pit.
Currect collecting net is made up of nickel or steel metal material.Nickel strap has equally distributed pit, be convenient to nickel strap and lithium sheet and currect collecting net good contact.
Beneficial effect:
The novel negative pole piece structure of new type lithium ion battery of the present utility model, adopt the collector-shoe gear that main flow collection sheet and Bifurcation Set flow combine, effectively can strengthen catchment effect, nickel strap has equally distributed pit, make nickel strap and lithium sheet and currect collecting net good contact, currect collecting net also can improve the effect of afflux, generally speaking, the novel negative pole piece structure of this new type lithium ion battery has structure simply, the advantages such as catchment effect is good, easy to implement.
