Description
Technical field
The present invention relates to a kind of lithium battery, especially relate to a kind of preparation method who adopts the full-solid-state minisize lithium cell of micro-processing technology preparation.
Background technology
In recent years, along with microelectromechanical systems (MEMS) technology rapid development, as: the fast development that microsensor, little gyro and Space Facilities are microminiaturized, relevant with it miniature energy technology also obtains people's attention more and more.Usually adopting external power supply is microelectromechanical systems (MEMS) power supply, can produce some defectives: as, reduced the design efficiency of MEMS; The noise that wiring point electric capacity produces; ([1] Koeneman P B, Busch-Vishniac I J, Wood K L.Journal of.Microelectromechanacal System.1997,6 (4): 355-362) such as interactive interference of supply lines and holding wire.Therefore, realize the microminiaturization of the energy, the integrated major issue that has become the solution of being badly in need of among the development MEMS with the defective that overcomes external power supply.In addition, very lagre scale integrated circuit (VLSIC) (VLSI) also to power supply proposed similar requirement ([2] Minko B..SolarEnergy Materials&Solar Cells, 2000,62:21-35).
In order to reduce the noise of power supply; Reduce the consumption ease of electric energy in the dynamic random container (DRAMS) that high density is arranged; Require in the actual production power supply and electronic equipment are connected as a single entity; Realize the miniature localization of the energy, the minicell that promptly quality of match is light, energy is high, the life-span is long on metal-oxide semiconductor (CMOS) storage piece.In the world the research of little energy is mainly contained several types of micro zinc-nickel battery, miniature lithium battery, miniature solar battery, miniature thermoelectric cell and micro fuel cells etc. in recent years.
Full-solid-state minisize lithium cell occupies critical role because of its integrated preferably compatibility in all kinds of minicells, also be to realize MEMS, microminiaturized, the integrated better selection of the VLSI energy.
It mainly is cathodic coating, solid electrolyte film and anode film that the structure of full-solid-state minisize lithium cell is formed.Relating to structure aspects has a variety of reports, and common structure can be described referring to U.S. Pat 5338625.Can be through deposition cathode current collector, cathodic coating, solid electrolyte film, anode film, anode current collector constitute successively on certain substrate (like monocrystalline silicon piece).The structure of battery has a variety of reports, and common structure such as U.S. Pat 5338625 are described.
The thin-film material that preparation constitutes micro cell mainly adopts micro-processing technology, as: methods such as magnetron sputtering, pulsed laser deposition, vacuum thermal evaporation deposition.
Because the reduction of thickness, electrolyte just can be used the poor lithium ion conductor-inorganic solid electrolyte of some ionic conductivities, for example employing rf magnetron sputtering Li under nitrogen atmosphere such as the Bates of U.S. Oak Ridge National Laboratory

Lithium anode film commonly used mainly is under the environment of high vacuum, to be deposited on the solid electrolyte with hot evaporation coating method.But in some integrated circuits (IC) manufacture craft, adopt reflow solder technique; In manufacturing process, IC is heated to 250～260 ℃ rapidly, because lithium has lower fusing point (180 ℃); Therefore when temperature surpasses 250 ℃, can lithium battery be destroyed because of the anode fusing.In addition,, react with airborne oxygen and water vapour etc. easily, therefore need a kind of anode material of miniature lithium ion battery of alternative metals lithium because lithium metal is very active.Research shows; Various metal oxides (for example tin-oxide and based on the composite oxides of tin) are anode material ([9] Neudecker of a kind of miniature lithium ion battery of fine alternative metals lithium; B.J., R.A.Zuhr, et al. (1999) .Journal of Power Sources 82:27-32); Its Heat stability is good, chemical property is more stable in air.The preparation method of metal-oxide film is easier, can be through a lot of methods magnetron sputtering for example, and thermal evaporation corresponding metal in oxygen atmosphere, the preparation of methods such as chemical vapour deposition (CVD).
In the technology of preparation battery, can use masks such as aluminium with special pattern, stainless steel to limit the shape of each component film of deposition micro cell; This mask technique is highly suitable for Centimeter Level or the more preparation of large scale battery; But rim effect can take place and can't obtain accurate figure in this mask method when preparation smaller szie micro cell; And there is pollution in mask in the deposit film process, also may scratch the film that has deposited and damages battery.Therefore, if micro cell will be applied on the various microdevices, its preparation technology must be compatible with microelectronics preparation technology.
