Description
Technical field
The present invention relates to the housing for primary cell, primary cell, storage battery and motor vehicle.
Background technology
No matter be in fixation application, for example, in wind power plant, in motor vehicle, for example, at motor vehicle driven by mixed power and motor vehicle, or for example, in consumer field, in notebook computer and mobile phone, through the fail safe of being everlasting, reliability, performance and used life aspect proposes higher requirement to used battery system.
An important parameter in the useful life in storage battery-mono-pond is energy density or capacitance, also depends on capacitance in addition by the haul distance of electric motor driven vehicle.Capacitance also can represent by per kilogram watt hour (Wh/kg) in weight.
The capacitance in storage battery-mono-pond or specified-capacitance are to be determined by the so-called active material in storage battery-mono-pond.For example the in the situation that of lithium ion list pond, this is graphite or carbon in metal oxide and the negative pole of the lithiumation in positive pole.In addition, in single pond, so-called inertia-material is also essential as separator and electrode adhesive for the function of cell.For optimization energy density people are devoted to reduce single pond-material part of inertia, wherein also comprise the housing in single pond, to correspondingly improve energy density.
In particular, lithium ion technique is particularly suitable for application widely.In addition, the salient point of lithium ion technique is embodied in that energy density is high and self discharge is extremely low.Lithium ion list pond has at least one positive electrode and negative electrode (positive pole and negative electrode), can reversibly embed (Intercalation) or deintercalation again (Deintercalation) lithium ion (Li+).Attractive storage battery-the system of the second be can recharge lithium metal-system.Here negative pole by lithium-metal make with positive electrode active materials for example taking have the transition metal oxide of layer structure as the cobalt dioxide of lithium (LiCoO2) as basis.
In order to carry out the embedding of lithium ion or the deintercalation of lithium ion, must there is bath composition, so-called lithium-conducting salt.In fact for whole current lithium ion single batteries, no matter be that (mobile phone, MP3-player or powerful tool) still all used lithium hexafluoro phosphate (LiPF6) as lithium-conducting salt in automotive field (hybrid vehicle-HEV) plug-in hybrid automobile (PHEV) and electric automobile (EV) in consumer field.Described LiPF6 is active especially for humidity, becomes fluorine hydrogen (HF) through multistage hydrolytic scission.
In order to prevent because the moist lithium ion list pond that the hydrolytic scission of conducting salt produces is damaged, use the housing with the metal part that is generally metallic film or sheet metal form according to background technology, wherein metallic film or sheet metal represent the obstruct to there was dampness in the air substantially.Wherein can be divided into the so-called Soft Roll with blister-pack and hard, the single pond in metal shell (hard box), described single pond is usually designed to prismatic and cylindrical.Described hard metal shell can be for example to make by aluminium with by cold deep-drawing technique.In this field, also do not show and used plastics, this is because conventionally have certain penetrability with respect to moist plastics.
But, compared with plastics, hard box is for example heavier in the situation that volume is identical by the hard box of aluminium or high-quality steel making.But in the aspect of single pond, improve special energy density owing to pursuing, reduce as much as possible the share of inert material.
In addition the housing being made of metal according to the natural law, externally conducts electricity.Can for example easily cause the high pressure-storage battery-intrasystem electric insulation problem between the basis-mono-pond connecting.
The in the situation that of mechanism, especially being caused metal shell to damage in this accident process by cracked or similar incidents, metal shell may cause internal short-circuit at Dan Chizhong.This may cause heating tempestuously, and open in single pond, and smoldering of single pond assembly, forms flame or even blast.For example when single pond in be full of electric state time, especially to note observe.
As for the share that how to reduce the inert material in storage battery, the housing film of known a kind of housing for fixing single pond from DE 10 2,008 023571 A1, described film is made and is arranged in the above the damp-proof layer of being made up of organo-silicon compound by polyolefin or similar material.But correspondingly the housing of design is easy to be subject to the danger to damaging and causing thus equally.
Also can each single pond be connected into battery module and connect into batteries again by being connected in parallel or being connected in series.Wherein formed by least two single ponds that connected according to a storage battery of definition.Can not use as synonym using these concepts of pond and storage battery that place an order.But contrary, storage battery, battery system, battery module and batteries will continue synonymously to use.
Summary of the invention
To provide a kind of housing for primary cell according to the present invention, damp-proof layer is made and disposed to described housing by carbon fibre reinforced plastic (CFK).
Preferably, primary cell relates to a kind of lithium ion battery or lithium battery that can recharge, and described battery especially can be moistureproof based on normally used active material.But also can be for other battery types according to housing of the present invention.
Professional person is known applicable carbon fibre reinforced plastic from background technology.Wherein preferably use thermoplastics and especially polyolefin and optimization polypropylene (PP) especially, polyethylene (PE) or their copolymer.Another kind of particularly preferred plastics are polyphenylene sulfide (PPS).
The known applicable carbon fiber with corresponding moulding and length of professional person.
Described carbon fibre reinforced plastic has good thermal endurance, outstanding anti-chemistry and mechanical stability.
With for example aluminium film is contrary, the plastics that use are moist transparent.Therefore in outside and/or the inner side of housing, moist impervious layer is set according to the present invention, wherein preferably on outside, manufactures described layer, this is because more simple and economical like this.Described damp-proof layer aspect humidity resistance can with metal film or sheet metal, for example aluminum-film is comparable.
Damp-proof layer can be by for example conventional method as chemical vapour deposition (CVD) (CVD), physical vapour deposition (PVD) (PVD) roll extrusion covering or similarly method apply.Certainly determine to take any method according to the layer that will apply.
Preferably, apply by CVD layer be by Parylene, organo-silicon compound be material or taking silicon dioxide as basis.Verifiedly especially be suitable as damp-proof layer taking silicon dioxide as basic layer.
Described layer also can be by the metal applying by PVD, for example aluminium or high-quality steel making.In the situation that being metal, also can use roll extrusion cladding technique, the thin metal layer wherein preferably applying by PVD.
In thin watertight composition " the Entwicklung einerhermetischen G1as-Silizium Verpackung Verkapselung (exploitation of seal glass silicon package film) " having been known for professional person and for example shown described above, be described to the housing of integrated lithium-polymer storage battery in DE102008023571A1 or at K.Marquardt etc.; MikroSystem Technik KONGRESS (KONGRESS microsystems technology company), Berlin, 2009,12-14.10.2010.
Can unexpectedly the favourable property combination of CFK be become to housing and the damp-proof layer for primary cell.Surprisingly, damp-proof layer can link together with CFK-housing long-term and stably.By reaching particularly preferred result by combined the glass barriers of carbon fiber RPP and sealing.
What do not make us expecting completely is; carbon fiber the inside in single pond chemically with electrochemistry on for the composition in single pond; for example organic carbon hydrochlorate, for example ethylene carbonate (EC), lithium-conducting salt, lithium hexafluoro phosphate (LiPF6) or micro-the fluorine hydrogen (HF) existing are inertia on long time, although carbon or graphite can react conventionally in corresponding environment.
Allow freely molded housing according to material used in the present invention, especially with the such as length of dimension of housing, the wall thickness aspect of width and height correlation.
