Description
Technical field
The utility model relates to a kind of lithium ion battery with Novel electric core structure.
Background technology
The afflux performance requirement of lithium ion battery to battery core negative plate is higher, and the negative plate of general lithium ion battery only has a flow collection sheet, and therefore, catchment effect is not ideal enough, therefore, is necessary to design a kind of novel lithium ion battery with Novel electric core structure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lithium ion battery with Novel electric core structure, and this lithium ion battery with Novel electric core structure has novel structure and the good advantage of catchment effect.
The technical solution of utility model is as follows:
Have a lithium ion battery for Novel electric core structure, comprise battery core, battery core comprises positive plate, negative plate and electrode;
Described negative plate 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 supplementary set flow (4);
Main flow collection sheet and supplementary set flow are L shape flow collection sheet;
First paragraph stretches out from the side of currect collecting net and lithium sheet, and second segment is transversely arranged on the bottom outside currect collecting net;
Supplementary set flow is connected with main flow collection sheet; Supplementary set flow and main flow collection sheet form rectangular-shaped afflux module in the scope of currect collecting net and lithium sheet.
Main flow collection sheet only has one end to be connected with supplementary set flow, and the other end does not connect.
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.This negative plate is good due to catchment effect, therefore, is conducive to the charge-discharge power demand meeting high-rate lithium battery.
Beneficial effect:
The lithium ion battery with Novel electric core structure of the present utility model, the collector-shoe gear that its negative plate adopts main flow collection sheet and supplementary set flow to combine, the rectangular shape of this collector-shoe gear is a kind of shape of substantial symmetry, than only adopting a slice flow collection sheet, catchment effect is better.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, it is simple that this lithium ion battery with Novel electric core structure has structure, the advantages such as catchment effect is good, easy to implement.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram of the negative plate of lithium ion battery of the present utility model;
Fig. 2 is the profile of negative plate.
The main flow collection sheet of label declaration: 1-, 2-currect collecting net, 3-lithium sheet, the flow of 4-supplementary set, 5-riveted holes.
