Description
Technical field
The utility model relates to the battery technology field, refers more particularly to a kind of leading-out terminal structure of liquid electrolyte lithium ion battery.
Background technology
Lithium ion battery divides two kinds of polymer lithium ion battery and liquid lithium ionic cells, poly-lithium battery all has stronger advantage aspect fail safe, volume, weight, capacity, the discharge performance, but because production capacity is lower at present, the manufacturing cost height, therefore hold at high price, price has become the bottleneck that the impact polymer lithium battery is popularized.
Liquid lithium ionic cell is widely used in communication, electron trade as a kind of high efficient energy sources carrier, particularly on person-to-person communication such as mobile phone, the PDA instrument.Nearly one or two years, along with the develop rapidly of mechanics of communication, indexs such as the capacity of liquid towards lithium battery, weight, chemical property and security performance are had higher requirement.
Present jumbo liquid lithium battery battery core adopts laminated structure more, the positive/negative plate that it is close with battery case with size, separate with barrier film by the centre, repeat repeatedly superimposed and form a bean curd bulk, after respectively positive and negative lug is connected on the anode and cathode terminals, put into metal-back, fluid injection forms.This inside battery electricity core has multiple lug, because being the metal forming by (0.01mm) as thin as a wafer, this one deck lug constitutes, so couple together and just occur the fracture of part lug especially easily, thereby the problem that battery performance and capacity are normally brought into play occurs influence, how lug is connected with terminal and electric current has been exported to a significant problem.
In addition, the liquid lithium ionic cell that energy density is high, comprise the fault of relevant device of charger and undue charging or other improper uses etc. and along with chemical reaction produces abnormal gas at inside battery, cell internal pressure is excessive, thereby the battery explosion accident takes place, its consequence is damage equipment then gently, and is heavy then hurt sb.'s feelings.Therefore, when cell internal pressure is excessive, for ease of gas leak, prevent the battery explosion accident, blast resistance construction is set on battery case usually, also high to the requirement of the derivation closed type of battery leading-out terminal simultaneously, Chinese patent ZL02216924 " a kind of lithium battery conducting strip that improves structure ", this conducting strip comprises that epimere is exposed, the substrate of hypomere and composite encapsulating material contact seal, the hypomere of substrate and composite encapsulating material contact seal position horizontal expansion add broadside, offer several through holes on substrate and composite encapsulating material contact seal position and broadside.When with composite encapsulating material conducting strip being carried out vacuum seal, softening encapsulating material infiltrates in the through hole on substrate and the broadside, after the cooling, solidifies in through hole and mutually combines, and as rivet conducting strip and composite encapsulating material is combined.Though such scheme has good sealing, complicate fabrication process.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, good airproof performance and lug is connected reliable lithium ion battery leading-out terminal structure with terminal.
The utility model is achieved through the following technical solutions:
Design a kind of derived type structure of lithium ion battery, battery case is provided with battery terminal, liquid injection hole and explosionproof hole, and the battery case upper end is provided with perforate, and hole wall is provided with insulating part, and the terminal and the lug that are positioned at the hole are connected and fixed by connector.Described connector can be a screw, and screw is positioned at the groove of terminal and lug joint one side; Described connector can also be mutually card and two clamping plates, the clamping plate that is positioned at terminals side and the clamping plate that is positioned at the lug side are by engaging or screw is connected clamping plate indention.
Described positive terminal is an aluminium matter, and negative terminal is copper, and the terminal cross section is circular, square or rhombus.
The utility model compared with prior art has following remarkable result:
Battery conductive terminal sealing type provided by the utility model is good, and connectors such as employing screw or clamping plate connect lug and terminal structure is simple and good connecting effect.
