Wide-temperature lithium bhatirikazhinji inoreva tembiricha yepamusoro lithium-ion mabhatiri, saka kana kuputika kukaitika panguva yekushandiswa, kuchava nemhedzisiro pabhatiri? Isu tinoziva kuti bhatiri sero rinowanzo ternary lithium bhatiri. Uye ikozvino kune akawanda masero akasiyana, akadai mamwe edu akajairika ternary lithium mabhatiri anoshandiswa graphite negative electrode, rudzi urwu rwezvinhu zveasina kunaka electrode, lithium primary mabhatiri akashandisa lithium cobaltate zvinhu zveiyo electrode yakanaka. Saka yakafara tembiricha lithium bhatiri inoputika pasi pekushisa kwakanyanya? Pano kugovana newe maonero akakodzera.
Sezvo zvinhu zvinoshandiswa mumasero ebhatiri emazuva ano, kusanganisira ternary lithium-ion mabhatiri ari lithium cobaltate, lithium iron phosphate uye zvimwe zvinhu zvekuita iyo yakanaka electrode. Saka ternary lithium bhatiri mune yakaderera tembiricha kana mukana wekuputika uri mudiki kwazvo. Asi mazhinji emusika wazvino wekupisa tembiricha lithium mabhatiri achashandisa kune lithium cobaltate seyakanaka electrode. Uye lithium iron phosphate inobva pane ternary lithium kuita electrode yakaipa; uye lithium cobaltate ndeyekuita electrode yakanaka; uye ternary lithium ion ndeyekuita electrode isina kunaka pane kuita yakanaka electrode. Izvi zvinotungamira kune shanduko mune yayo bhatiri chimiro.
Kugadzirisa dambudziko rekuchengetedza kweyakafara tembiricha lithium mabhatiri, kiyi ndeyekuvandudza kuchengetedzwa. Chekutanga, bhatiri sero inofanira kunyatsodzorwa, inovawo vimbiso yekushanda kwebhatiri uye inogona kunyatso dzivirira mukati mapfupi dunhu kana kuwandisa panguva yekushanda kwebhatiri, pamwe nekudzivirira kuitika kwekupisa kwemukati kwebhatiri. , zvichikonzera kuputika kwebhatiri. Uye mukushandiswa kwezuva nezuva kunofanirwawo kutarisisa kuhupenyu hwakachengeteka hwebhatiri uye kudzivirira kupisa kwebhatiri, kuwandisa uye mamwe mamiriro. Tevere, tinofanira kutarisisa kukanganiswa kwekushisa pabhatiri. Iyo tembiricha yebhatiri yakanyanyisa kuchengetedzeka kwehupenyu hwedu kuchaunzawo njodzi. Naizvozvo, kana zvigadzirwa zvebhatiri zvichida kushandiswa zvirinani muhupenyu hwedu hwezuva nezuva, isu tinofanirawo kuterera kune basa rekudzora tembiricha yebhatiri.
Kubva pakuchengetedzeka kwekuona, kana tembiricha yebhatiri yakanyanya, lithium-ion mabhatiri anogona kuitika thermal runaway combustion phenomenon. Izvi zvinodaro nekuti iyo lithium ion iri mubhatiri yelithium-ion inonyanya kuumbwa nemadonhwe emvura, madonhwe emvura akawanda, iyo inokwira tembiricha yerithium-ion bhatiri, kana iyo lithium ion mu electrolyte yakawandisa kutama, kupararira kuchaita Lithium ion irreversible migration inotungamira kubhatiri kupfupi-circuit kupisa kwega, etc. bhatiri moto kana kuputika. Nokudaro, kubva pakuona kwekuchengeteka, kushandiswa kwekushisa kwe lithiamu-ion mabhatiri kunofanira kuvharwa panguva yakakodzera. Mukuwedzera, kana kutonhora kwakanyanya, zviri nyore kukonzera mukati pfupi-circuiting uye nokudaro kukonzera moto uye kuputika. Mukuwedzera, kubva panzvimbo yekuchengeteka kwekuona kwebheteri yesimba, kana isiri iyo yakazara kuchengetedzwa kwekuongorora uye kushandiswa kwemhepo inopisa inopisa ye lithiamu-ion battery inogona kuputika.
Muchokwadi, iyo yakafara tembiricha lithium bhatiri yakachengeteka kushandisa nekuti inosangana nezvinodiwa zvekuchengetedza mabhatiri e-lithium-ion muGB18483-2001 Safety Technical Specification yeLithium-ion Batteries, iyo inonyanya kuenderana nemaitiro ekuchengetedza. Asi nekuda kwekuti chigadzirwa chitsva, hapana chakajeka chiyero chenyika uye indasitiri zviyero zvinotungamira kuvandudzwa kwehunyanzvi uhu, saka isu tinofanirwa kusanganisa kushandiswa kwekunzwisisa chaiko. Muchishandiso chekushandisa chinoda kudzivirira kusangana nekushisa kwakanyanya, static magetsi, pamusoro pekubuda, kuburitsa uye zvimwe zvinhu zvine njodzi, zvikasadaro zviri nyore kukonzeresa kuputika kwepakati. Saka mukushandiswa kwemazuva ese kunofanirwa kutarisisa kushandiswa kwakachengeteka kweyakafara tembiricha lithium mabhatiri pamwe nekuchengetedza uye kushandiswa kwakachengeteka.
Izvo zviri pamusoro ndezvekuti iyo yakafara tembiricha lithium bhatiri ichaputika uye yakafara tembiricha lithium bhatiri zvine chekuita nemukati.
