Abstract
The utility model discloses a lithium ion battery with a novel electrode plate structure. The rolled core of the lithium ion battery is formed by winding a pole piece and a diaphragm; the edge area of the bottom layer of the pole piece along the length direction is not provided with an active layer; the rest areas of the bottom layer of the pole piece are provided with active layers; the pole piece comprises a positive piece and a negative piece; the tabs of the positive piece and the negative piece are separately arranged at two ends of the rolled core; and the bottom layer of the pole piece is an aluminum foil or a copper foil. The lithium ion battery with the novel electrode plate structure has the advantages of low internal resistance and excellent discharge performance.
Description
Technical field
The utility model relates to a kind of lithium ion battery with novel electrode pole piece structure.
Background technology
Electronic toy, instrument; The fast development of model plane etc.; Requirement to the multiplying power discharging property of lithium ion is also increasingly high; Existing lithium ion battery, its positive/negative plate are all drawn from an end of volume core, and battery can influence the heavy-current discharge performance of battery because positive and negative lug width is not enough when banishing electricity greatly.
The utility model content
The utility model technical problem to be solved provides a kind of lithium ion battery with novel electrode pole piece structure, and this lithium ion battery with novel electrode pole piece structure has the advantage that internal resistance is little and discharge performance is good.
The technical solution of utility model is following:
A kind of lithium ion battery with novel electrode pole piece structure; The volume core of lithium ion battery is formed around volume by pole piece and barrier film; A pole piece bottom fringe region is not along its length established active layer; All the other zones of pole piece bottom are provided with active layer, and pole piece comprises positive plate and negative plate, the two ends of the volume core that the lug branch of the lug of positive plate and negative plate is located at.
The bottom of pole piece is aluminium foil or Copper Foil.
The bottom that active layer is not set of positive plate or negative plate (bottom that promptly exposes, aluminium foil or Copper Foil) welds together.
Beneficial effect:
The lithium ion battery with novel electrode pole piece structure of the utility model; The both positive and negative polarity lug stretches out at the two ends of volume core respectively; Solved positive and negative lug and gone out the problem that the lug width is restricted in same direction, battery can not influence the heavy-current discharge performance of battery because the lug width is not enough when banishing electricity greatly.
The copper aluminium foil welds together simultaneously, greatly reduces the internal resistance of cell, has improved the high-rate battery discharge performance.The mode of reeling with respect to lamination technology, has improved production efficiency, has practiced thrift cost.
