Abstract
The invention relates to a secondary lithium battery. Wherein, the anode flow collector is foam aluminum and/or cathode flow collector is foam copper, foam nickel or foam iron. The invention also provides a relative secondary lithium battery group formed by single lithium battery.
Description
Technical field
The present invention relates to use the secondary lithium battery or the battery pack of the collector that foam metal makes.In the monomer lithium ion battery, make one of at least in plus plate current-collecting body and the negative current collector by foaming structure especially foam metal, for example plus plate current-collecting body is a foamed aluminium, negative current collector is foam copper, nickel foam or foam iron.The invention still further relates to the secondary lithium battery group of forming by above monomer lithium ion battery.
Background technology
The present invention relates generally to lithium ion battery.At present along with market for the improving constantly of the performance requirement of lithium ion battery, the energy density of customer requirements lithium ion battery is higher, heavy-current discharge performance is better.Each lithium ion battery manufacturing firm constantly researches and develops at above customer requirement, to promote the energy density of battery by the utilance that improves the battery useful space; The electro-chemical activity of active material of more effectively bringing into play battery is to improve its effective rate of utilization.
The method that fundamentally improves lithium ion battery energy density and chemical property is the positive and negative pole material that the new energy density of invention is higher, can be used for lithium ion battery.Next is how to reduce the invalid space of battery, increases the loading of active material (positive and negative pole material), perhaps takes suitable physics or chemical method to improve the utilance of active material.Can adopt following means for a kind of method in back: adopt thinner collector and barrier film; Adopt more effective additive to improve the effective rate of utilization of active material.
Still need to continue to improve secondary lithium battery energy density and chemical property at present.
Summary of the invention
At the requirements at the higher level for performance index such as lithium ion battery energy density and multiplying power dischargings, present most of lithium ion battery manufacturing firm all is by adopting thinner collector and barrier film; Adopt more effective additive to improve the effective rate of utilization of active material.Yet by a large amount of experiments, the inventor finds, compares with the paper tinsel class of present use such as Copper Foil, aluminium foil, adopts the collector of metal foam as lithium ion battery, significantly improved the capacity and the multiplying power discharging property of lithium ion battery.
In one embodiment of the invention, metal foam can be the two-phase composite material that comprises continuous phase and the pore decentralized photo or the continuous phase of metallic matrix skeleton.
Do not wish to be subjected to the restriction of any theory, thereby adopt metal foam to replace traditional paper tinsel collector to improve the capacity of lithium ion battery in the present invention and the reason of multiplying power discharging property can be presumed as follows.Owing to exist the three-dimensional pore space of porous in the foam metal, can be so that active material be filled in this hole, rather than as paper tinsel body collector, can only be coated in its surface.And after active material is filled in the porous three-dimensional pore space in the foam metal, not only increased filling rate, and because the three-dimensional pore space structure of foam metal itself and even distribution that porous more helps current density and electrolyte permeability, evenly distribution, thereby can improve the active material utilization of lithium ion battery, improve the capacity and the multiplying power discharging property of lithium ion battery.
On the contrary, for metal foil, active material can only be distributed in the surface of collector.The electric energy that changes into chemical energy mainly passes to active material by collector, and (be that active material changes into chemical energy with electric energy in the charging process, this process is an energy input process; Use is a discharge process, by discharge chemical energy is changed into electric energy, and this process is the output procedure of the energy.) near the active material of collector with mix widely differently at the branch of electric energy away from the active material of collector, the closer to collector, many more whiles of the electric energy that it distributed are also even more, more away from collector, the electric energy that it distributed is few more.As can be seen since the metal foil that affluxion body in lithium ion batteries adopts has caused the input and output of lithium ion battery active material and in conversion process the inhomogeneities of energy, had influence on the raising of active material utilization.
The inventor has made the collector that a large amount of experiments improve lithium ion battery, improves the energy density and the multiplying power discharging property of lithium ion battery by the improvement of collector.This also is the main purpose that the present invention will reach.
Reach above purpose, the present invention has proposed following solution by a large amount of experiments.The lithium ion battery that utilizes this programme to make comprises with the lower part: electrode, electrolyte, barrier film, container.Wherein electrode comprises positive pole and negative pole, and positive pole comprises plus plate current-collecting body and positive active material; Negative pole comprises negative current collector and negative electrode active material; Barrier film can be simple solid insulating layer, also can be jello, also can be the decorating film with electric conductivity; Container is positive pole, negative pole, barrier film, electrolytical inclusion body, can be that the container with solid shape also can be the container that is made by thin-film material.
In a preferred embodiment of the invention, one of at least comprise foam metal in plus plate current-collecting body in the secondary lithium battery and the negative current collector, for example plus plate current-collecting body is a foamed aluminium, and negative current collector is foam copper or foam iron or nickel foam.Satisfying under the condition of above-mentioned feature, current density and electrolyte can obtain even distribution in the battery, can improve the space that utilizes of the interior active material of battery, can improve the energy density of battery and the multiplying power discharging property of battery.
