Description
Technical field
The present invention relates to a kind of method of detection, relate in particular to a kind of method that can make electronic cigarette battery detect by acupuncture.
Background technology
Electronic cigarette has another name called virtual cigarette, it has the outward appearance the same with cigarette, the taste approximate with cigarette, even than the taste of general cigarette, to have more a lot, also energy sucking-off cigarette as cigarette, sucking-off taste comes with sensation, electronic cigarette wherein a kind of component is electronic cigarette battery, the quality of its quality directly affects the quality of electronic cigarette, for guaranteeing the quality of electronic cigarette battery, now a lot of producers answer client's demand to cross lancing test technique through one, test process is pierce through battery and keep 2 hours with the nail that diameter is 3mm, if reach not on fire, do not explode and meet the demands.If according to conventional electrical cigarette battery design, cannot guarantee that each electronic cigarette battery crosses lancing test requirement, the present invention designs by Optimization Technology, can realize electronic cigarette battery in batches by lancing test requirement.
Summary of the invention
The object of the present invention is to provide a kind of method that can make electronic cigarette battery detect by acupuncture, the method is simple and practical, can improve greatly electronic cigarette battery and pass through acupuncture detection, reaches not on fire, does not explode, and guarantees the object of electronic cigarette battery quality.
The present invention is achieved like this, and it is characterized in that method step is:
(1) adjust battery plus-negative plate face Capacity Ratio, guarantee that battery cathode is excessive enough to bear the lithium ion that anode moves out, guarantee that battery is full of electric negative pole and does not inhale lithium;
(2) high temperature gummed tape is pasted in the position of the super weldering of anode head anode ear, covers whole empty paper tinsels, and what the rich material of assurance negative pole was corresponding is anodal high tempreture tape rather than empty paper tinsel;
(3) at the empty paper tinsel of anode afterbody, use the green terminal adhesive tape of 8-12mm width to paste with expecting junction, wherein 2-3mm is attached to material above, and 6-9mm is attached to above sky paper tinsel, and what the rich material of assurance afterbody negative pole was corresponding is high tempreture tape rather than aluminium foil sky paper tinsel;
(4) at anode afterbody, increase the empty paper tinsel of aluminium foil of 1 circle length, negative pole afterbody increases the empty paper tinsel of 1 circle length, can guarantee that like this heat that moment produces is delivered in time battery surface and distributes, and prevents that battery excess temperature from raising;
(5) barrier film adopts the coating barrier film of one side coating aluminium oxide, has guaranteed that temperature exceedes the automatic closed pore of certain value, stops inside battery to continue reaction;
(6) electrolyte adds appropriate flame-retardant additive (not affecting chemical property), improves the decomposition temperature of electrolyte.
Advantage of the present invention is: can improve greatly electronic cigarette battery and pass through acupuncture detection, reach not on fire, do not explode, guarantee the object of electronic cigarette battery quality, simultaneously for what improve battery, overcharge safety test performance, short circuit safety test performance, thermal shock safety test performance and extruding safety test performance are also very helpful.
Embodiment
(1) the both positive and negative polarity face Capacity Ratio of original battery design is generally 1.06, very high to the stability requirement of pole coating face amount, if the fluctuation of coating pole piece face amount is large, cannot guarantee that negative pole face amount is definitely greater than anodal face amount, will cause like this suction lithium, lithium metal is very active, be easy on fire, cause acupuncture to pass through, the present invention adjusts battery plus-negative plate face Capacity Ratio, guaranteeing that battery cathode is excessive enough bears the lithium ion that anode moves out, guarantees that battery is full of electric negative pole and does not inhale lithium.
(2) what the rich material of original anodal electronic cigarette design head negative pole was corresponding is anodal empty paper tinsel, due to can gesture in battery the highest be aluminium foil anticathode powder, then be positive pole powder anticathode powder, can react liberated heat maximum in the highest place of gesture, battery acupuncture is more on fire, the present invention pastes high temperature gummed tape by the position of the super weldering of anode head anode ear, covers whole empty paper tinsels, and what the rich material of assurance negative pole was corresponding is anodal high tempreture tape rather than empty paper tinsel; At the empty paper tinsel of anode afterbody, use the green terminal adhesive tape of 8-12mm width to paste with expecting junction, wherein 2-3mm is attached to material above, and 6-9mm is attached to above sky paper tinsel, and what the rich material of assurance afterbody negative pole was corresponding is high tempreture tape rather than aluminium foil sky paper tinsel.
(3) original general electronic cigarette battery design negative pole afterbody does not have sky paper tinsel, but due to can gesture in battery minimum be that aluminium foil is to Copper Foil, if the aluminium foil that battery acupuncture potential energy is minimum first contacts with Copper Foil, the heat minimum producing, battery acupuncture portion is easily on fire, the present invention increases the empty paper tinsel of aluminium foil of 1 circle length at anode afterbody, negative pole afterbody increases the empty paper tinsel of 1 circle length, can guarantee that like this heat that moment produces is delivered in time battery surface and distributes, and prevents that battery excess temperature from raising.
(4) general tri-layers of barrier film of three layers of PP/PE/PP that use of original electronic cigarette battery, this barrier film exceedes 150 degree in temperature and will burn, and the ignition temperature of the coating barrier film of one side coating aluminium oxide can reach 200 degree, as long as battery instantaneous temperature is in 200 degree, barrier film still can be not on fire, greatly improved the fail safe of battery acupuncture, and barrier film of the present invention adopts the coating barrier film of one side coating aluminium oxide, guaranteed that temperature exceedes the automatic closed pore of certain value, stoped inside battery to continue reaction.
(5) normal electronic cigarette battery does not add fire retardant, not adding fire-retardant electrolyte spends between-155 degree and just may burn in temperature 130, and the electrolyte battery ignition temperature of adding fire retardant can be brought up between 150 degree-185 degree, greatly improved the security performance of battery acupuncture, electrolyte of the present invention adds appropriate flame-retardant additive (not affecting chemical property), improves the decomposition temperature of electrolyte.
