Description
Technical field
The invention discloses the synthesizing porous composite strip technology of a kind of controlled solution combustion, belong to new material technology field.
Background technology
The sustainability of the energy and environment is the severe challenge of face of mankind, taps a new source of energy and clean reproducible energy is one of material technical field of tool in the 21 century World Economics.Regenerative resource such as solar energy, wind energy, and new-energy automobile is gentle important channel and the means of separating environment pressure of the global energy crisis of reply.As the critical component of power conversion and storage, electrochemical energy storage device has occupied more and more important position in the development of new forms of energy industry, and has become the main factor of restriction whole industry development.No matter at the energy-storage system of regenerative resources such as solar energy, wind energy; Or the dynamical system of new-energy automobile; And in the peak regulation stored energy application of intelligent grid, electrochemical energy storage device is core component, and its technical merit plays crucial effects to the whole system performance.But the power storage that how to realize the low cost scale becomes one of core technology problem of regenerative resource development and application.
With regard to present energy storage technology level, limited stored energy capacitance, power density and expensive material and manufacturing cost are to realize crucial restraining factors low-cost, the large-scale electric energy storage.Up to now; In the 2.8～2.9Ah that has highest energy density, 18650 type lithium ion batteries (>=600 Wh/L) lining; Electrode active material accounts for half the less than the battery effective volume, and what account for most of volume capacity is the expensive non-active materials such as metal collector paillon foil, barrier film, liquid electrolyte, binders for electrodes and conductive additive of cost.These non-active material proportions have seriously limited the energy storage density of battery and the further raising of power density, also are simultaneously that the bottleneck that restriction battery manufacturing cost continues to reduce belongs to.One of effective way that solves this technical barrier is to optimize the micro-structural of electrode, and the recycle efficient that improves active material also reduces the non-active material proportion in the energy storage device, thereby improves the performances such as whole volume, power density of energy storage device.
More about the research report of electrode microstructure control in the recent period, mainly be characteristic size, thereby obtain the electrode material of nanostructure through the shortening electrode active material, make ion/electrical conductivity stroke shorten, realize high energy density and power density.For example, Yao etc. are the three-dimensional collector of commercial foam metal nickel as electrode material, and the power density ratio that obtains adopts conventional aluminium collector paper tinsel slightly to improve.But the increase rate of battery performance mainly is subject to macroscopical three-dimensional structure (pore-size is about 200～500 μ m) of commercial nickel foam.Braun etc. produce the Ni-based three-dimensional net structure matrix of orderly nanoscale based on self assembly template+electronickelling technology, in orderly nanoaperture, fill electrode active material then.Taberna etc. have successfully prepared the copper-based nano columnar arrays based on the electrochemical deposition technique of orderly template, on the copper nano-pillar, have deposited one deck Fe then
3O
4Oxide coating.Simultaneously, the carbon-based nano structure comprises that nano wire, nanotube and nanometer foam etc. because its excellent electric conductivity, also are widely used as the electrode suppor material, with the raising of the energy density that realizes energy storage device.
Yet the preparation process of above-described various three-dimensional structure electrodes is more loaded down with trivial details usually, needs a plurality of steps to accomplish.For example nickel, copper three-dimensional architecture material at first need prepare template, then through chemistry or electrochemical method plated metal on template, remove mould material afterwards again and obtain the three-dimensional architecture electrode, finally are filled into electrode active material in the three-dimensional architecture electrode.Too loaded down with trivial details preparation process will cause the electrode material preparation cost than higher, is unfavorable for the large-scale application popularization.
Summary of the invention
