Description
Technical field
The present invention relates to the preparation field of lithium battery collector, relate in particular to the method that the compound PTC powder of a kind of electrostatic coating macromolecule is prepared lithium battery collector.
Background technology
In lithium battery applications process, in the time that inside battery is short-circuited as the situation such as acupuncture, sharp impacts, immediate current sharply increases, cause battery-heating, cause thus a series of chain reaction, finally cause lithium battery blast on fire, for tackling this phenomenon, someone pastes and prevents at the connecting circuit of battery or the housing of battery with PTC transducer, because these devices and parts are the outsides at lithium battery, can not obtain in time lithium battery interior intensification information and react in time, causing prevention to lag behind, can not meet the object of lithium battery security protection.
Along with scientific and technical develop rapidly, social every profession and trade is composite material, electronic material particularly, and decorative material etc. increase day by day to the demand of functional lithium battery collector.Functional lithium battery collector has become the critical material of the PCB that plays support, interconnection components and parts effect in the functional energy and electronic system product at present, and it is called " neural net " of electronic product signal and electric power transfer, communication.Lithium battery collector is as the basic material of electronics industry, and the development of PCB technology is being followed in its development always, and PCB technology is along with the with rapid changepl. never-ending changes and improvements of electronic product improves constantly.The development of IT product technology has promoted PCB towards multiple stratification, slimming, densification, high speed, highly reliableization, functionalization future development, and it is boundless that therefore exploitation has the lithium battery collector market prospects of high-performance, high-quality, high reliability, functionalization more.
Since the people such as the Heyman of Philips company of nineteen fifty Holland find can to obtain positive temperature coefficient (PTC) characteristic after BaTiO3 is ceramic semiconducting, people are more and more deep to its understanding.Meanwhile, also just increasingly extensive in its application aspect, be penetrated into the every field such as daily life, industrial or agricultural technology, military science, communication, aerospace.PTC thermistor heater element is the modern product down to high-tech tip in future.It is widely used in light industry, house, traffic, space flight, agricultural, medical treatment, environmental protection, mining, civilian apparatus etc., and it,, compared with the heater elements such as nickel, chromium silk or far infrared, has advantages of remarkable.When apply interchange or direct voltage intensification at PTC element, below Curie-point temperature, resistivity is very low; Once when surmounting Curie-point temperature, resistivity increases suddenly, make its electric current drop to stationary value, reach A.T.C, constant temperature object.Not rubescent when PTC element heating, the flames of anger (resistance wire rubescent and have naked light), nonflammable.When PTC component ambient temperature exceeds limit value, its power drops to equilibrium valve automatically, can not produce danger of combustion.The energy input adoption rate formula of PTC element, current limiting effect, also saves electric power than the switching regulator energy input of the heater elements such as nickel filament.Ptc material has two kinds of macromolecular material class and ceramic-like, ceramic-like PTC element this as oxide, the high-temperature oxydation drawback of Ni-Cr free silk, does not have the frangible phenomenon of infrared tube yet, the life-span is long.And porous type is longer than the anapsid life-span.PTC element itself is temperature automatically controlled, does not need separately to add A.T.C line unit.Porous type PTC does not more need other heat abstractors, does not need to use conducting resinl yet.PTC element can normally use under low pressure (6-36 volt) and high pressure (110-240 volt).Low pressure PTC element is applicable to all kinds of low-voltage heaters, instrument low temp compensating, the heater on automobile and on computer peripheral device.High pressure P TC element is applicable to the heating of following electric equipment: electric thermal-insulation plate, shoe baking device, thermosol gelgun, electric cooker, electric shoes, electric mosquito heater, intravenous injection heating, light-weight plastic closing machine, steam hair comb, steam generator, humidifier, curler, video tape recorder, photocopier, automatic vending machine, hot-air screen, hand warmer, tea drier, Water pipe heating device, travelling dryer, finish-baking room for automobile, liquefied gas bottle heater, shower, beauty care device, Electric heating table, baby bottle thermostat, electric heating moxibustion instrument, electric hot water bottle, electric blanket etc.
The appearance of ptc material, the fast not and capacity problem of this two aspect not greatly of the speed that can solve traditional switch.Along with updating of scientific and technical development and technique, the characteristic of PTC element will be more and more perfect, its normality can will be further improved by galvanization, may cause a field technology revolution of traditional switch in AC and DC field, also have a wide range of applications for linear quadratic control equipment, it will reduce the manufacturing cost of electronic equipment greatly, improves economy, the reliability of electronic system operation.
Ptc material is processed due to barium titanate ceramics material, and the control of tradition processing homogeneity is more difficult, has limited the application of ptc material.
Tradition preparation PTC components and parts are due to the restriction of technique, and PTC components and parts and electrode are processed respectively, then weld or are cemented to device with pole plate, take Miniature component as main, there are no the report of jumbo ultra-thin function lithium battery collector processing.
