Abstract
The utility model discloses an aluminium case lithium ion battery which comprises a positive plate and a negative plate which are arranged in a case body, electrolyte and the case body, wherein the positive plate coats positive active material layers on the two sides of a positive current collector, and the negative plate coats negative active material layers on the two sides of a negative current collector, the negative plate is connected with the lug of a metal strip and extends out to form a negative lug, and plastic material is sealed on the negative lug in a heat sealing manner. Compared with the prior art, the utility model has the following advantages that: the insulation plastic can resist high temperature of 140 DEG C to 220 DEG C and electrolyte, thereby increasing the mechanical strength and the electrolyte resistance performance between the negative lug and the insulation plastic, and the insulation plastic of the negative lug can not melt caused by the large transient current of the spot welding during the working process.
Description
[technical field]
The utility model relates to the battery product field, more particularly, relates to a kind of aluminum hull lithium ion battery.
[background technology]
Lithium ion battery is a kind of big capacity, high-power battery, is mainly used on the mini-plant, as mobile phone, digital product, portable power tool etc.The aluminum hull lithium ion battery plurality of advantages such as does, easily shapes because of its light weight, security performance and promoted rapidly.
The aluminum hull lithium ion battery is owing to discharge and recharge strict voltage, electric current restriction, therefore, when assembling, the production of aluminum hull lithium ion battery to particularly pay attention to the Insulation Problems between the positive and negative electrode, otherwise, cause the short circuit of aluminum hull inside lithium ion cell to burn out battery probably, even may cause serious accident.
The aluminum-shell battery negative electrode lug of producing is to wrap on the lug so that insulate with anode ear with a kind of gummed paper at present, yet, this kind gummed paper came off after steeping electrolyte easily, and damaged easily in assembling process, had stayed very big hidden danger for the production and the use of aluminum hull lithium ion battery.
In view of above drawback, be necessary to provide a kind of improved aluminum hull lithium ion battery to overcome above-mentioned defective in fact.
[utility model content]
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of aluminum hull lithium ion battery is provided, so that strengthen the insulating properties between the battery positive and negative electrode.
For achieving the above object, the utility model adopts following technical scheme: a kind of aluminum hull lithium ion battery, comprise the positive plate that is arranged in the housing, negative plate, electrolyte and housing, positive plate is plus plate current-collecting body two sides coating positive electrode active material layer, negative plate is negative current collector two sides coating negative electrode active material layer, the negative plate bonding ribbon lug formation negative electrode lug that stretches out has been sealed up plastic material in the mode of heat-sealing on the described negative electrode lug.
Described positive active material is made of lithium and cobalt oxides or LiMn2O4, LiFePO4, nickle cobalt lithium manganate, conductive agent, adhesive; Described negative electrode active material is made of graphite or lithium titanate, conductive agent, adhesive.
Compared to prior art, the utlity model has following advantage: this kind insulation plastic cement can anti-140 ℃～220 ℃ high temperature, electrolyte resistance, mechanical strength and electrolyte resistance performance between negative electrode lug and the insulation plastic cement have been increased simultaneously, and lug insulation plastic cement is melted, in addition, making negative electrode lug insulation plastic cement with the mode of heat-sealing plastic cement replaces gummed paper to do the insulation of negative pole, the former is safer, assemble more conveniently, thin model is especially remarkable for producing.
