Description

A kind of battery that substitutes barrier film with supersonic generator

Technical field

A kind of battery that substitutes barrier film with supersonic generator belongs to field of batteries.Battery is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that chemical energy is directly become electric energy, and the ultrasonic generator that the present invention proposes is applicable to rechargeable battery and fuel cell especially.

Background technology

The utilization of traditional energy has two large disadvantages: the one, and be stored in and could be become mechanical or electrical energy after chemical energy in the fuel must at first change heat energy into, its efficient that obtains only has 33%-35%, and energy over half wastes; The 2nd, the mode of utilizing of traditional energy has caused huge pollution to environment.

In recent years, do not stint for the research and development of encouraging the new forms of energy car and employ government's substantial contribution support in various countries, the whole world, even the newly energy car of research and development of all working in coordination between several big countries, so the new forms of energy car here just needn't carefully be said, and the place that present new forms of energy car is seized by the throat most, what just be with the energy that is used as power, the problem of power source namely, except petroleum fuel, everybody is looking for new energy source of car, because bioenergy and the mankind strive grain, do after a while bioenergy calmness go down, finally everybody sight all concentrates on the battery power, now basically more than 95% all take the research of cell electric vehicle as main, and high-power power battery just becomes the research object that various countries competitively drop into.

At present electric motor car all concentrates on this field of battery basically, and mainly concentrates on the following four large class electrokinetic cells.

1, ickel-cadmium cell: ickel-cadmium cell during the Second World War German is at first invented, has relative low price, cross and put, consistency of battery pack is good by overcharging resisting for long service life (2000 times more than the cycle life), the use procedure safety non-pollution, be convenient to the advantages such as maintenance, its weak point is that energy Ratios is not high, and the negative pole cadmium is in process of production to human body and environment, based on these two hard defects, this battery does not receive greatly to pay attention to;

2, Ni-MH battery: Ni-MH battery is developed for solving the harm of cadmium nickel negative pole, energy Ratios also increased when it had inherited the ickel-cadmium cell advantage, can be described as reasonable a kind of battery, weak point is voltage or 1.2V, comparing with ickel-cadmium cell is slightly having gap aspect performance and battery pack life-span (more than 1000 times), large-sized power battery applications example is seldom only used more than the mini-type motive power at model plane electric tool etc.

3, nickel-zinc cell also has been developed more than hundred year, its advantage is electromotive force high (1.6V) energy density (more than the 120W/ liter) low cost of manufacture, the advantage such as pollution-free, why it does not obtain large batch of application, be that the brilliant problem of negative pole zinc skill can not get solving for a long time, consistency of battery pack is poor simultaneously to cause useful life short (more than 300 time), before the brilliant problem of zinc skill does not thoroughly solve, be not suitable for using, although recent year has some researchers of enterprise and the U.S. to cooperate, that is that all right is ripe for technology.

4, to have a volume little for lithium iron battery, lightweight leading advantage with high energy ratio and high electromotive force, and not enough place is that battery consistency is poor and causes the life-span short, and on the high side, security performance is without guarantee.(four class cell evaluations are selected from web material, and the author is unknown, with greetings)

At present, what various countries dropped into maximum is lithium iron battery, and the electronic concept car that each depot releases in the several times car exhibition recently all is the lithium battery car.

But lithium battery causes it commercial to use as its several large shortcomings of power source, and at first being rechargeable battery has its limit as automobile-used, a trickle charge 6-8 hour, filled soon 30 minutes, then each occupation of land of filling soon the station will have the place as a large parking lot, and this is unpractical.And fill soon and can greatly shorten battery life.The second, filling at present once, the electric weight of electricity does not satisfy needs.All concept cars are all between 30-60 degree electricity at present, flying power is no more than 200 kilometers, and through after repeatedly charging, flying power can descend greatly after battery capacity descended, do not satisfy long-distance needs, the 3rd, fail safe is low, can both hurt sb.'s feelings as long as think about it the battery of mobile phone blast, just well imagine for the result behind the battery explosion of a hundreds of kilogram.The 4th, manufacturing cost is high, because lithium is rare metal, this resource can be more rare after the large-scale application, and cost only can be more and more higher.

The metal electrode of above battery in use can passivation, affect generating capacity, therefore between electrode barrier film must be arranged, membrane process is complicated, technical difficulty is large, it is high to require, cost is high, the life-span is limited, and high-end membrane technique wherein only has America and Japan to grasp now.

The utility model people breaks the pattern of existing battery, proposes without diaphragm cell, and it need not battery diaphragm, greatly reduces cost, improves performance.Its technical scheme is to adopt the reaction principle of battery, using ultrasound wave producer to solve the problem of passivation of electrode, avoids the short problem of battery life.So, particularly important to the selection of supersonic generator technical parameter.

Summary of the invention

A kind of battery that substitutes barrier film with supersonic generator that the utility model proposes its objective is and not use barrier film in battery, and guarantees the normal and best operating state of battery.

The utility model adopts supersonic generator to make electrolyte produce cavitation to electrode, eliminates the passivation of electrode.

Embodiment

Now this is described without the diaphragm cell scheme with concrete example, Fig. 1 is its structural representation, and it is comprised of positive electrode 1, electrolyte 2 and negative electrode 3, and electrolyte is contained in the battery case 5, and supersonic generator 4 usefulness viscose glues are fixed on the outer wall of battery case 5.During use, start supersonic generator, the ultrasonic wave of its generation makes electrolyte produce void effect, and when in the hole of electrode surface explosion occuring, the force of explosion of generation is eliminated the passivation of electrode.

Yet the quality of passivation depends on hyperacoustic frequency, power cooperates with electrolyte.Pay effort and the checking of hardships through the inventor, drawn the data of ultrasonic frequency.Now lift the explanation of part fact Example.

Example one electrolyte prescription 1, ultrasonic frequency is 28K, power 5W/L, the peak value uninterruptable power generation time is more than 4 hours.
