Iyini imbangela yesigubhu sebhethri le-polymer? Indlela yokulungisa

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Umhlinzeki Wesiteshi Samandla Esiphathekayo

Izimbangela nezisombululo zesigubhu sokunwetshwa kwebhethri ye-lithium ye-polymer. Amabhethri e-lithium e-polymer, amabhethri e-lithium iron phosphate, njll. besaba kakhulu i-short-circuit ebhethrini, isifunda esifushane ngaphandle kwebhethri, ukushajwa ngokweqile.

Izigubhu zebhethri ze-lithium zibangelwa ukunikezwa kokunqwabelana kwekristalu ye-dendritic ngenxa yamapuleti amhlophe. Ezimweni eziningi, isigamu kuphela samandla aphezulu naphansi aqalisiwe, futhi akhiphe ngokuphelele futhi aqedele ukugcinwa kokushaja enanini elincane kakhulu lamacala. Izimbangela zezigubhu zebhethri le-polymer kanye nokulungisa amabhethri e-lithium athambile e-polymer abizwa ngokuthi amabhethri e-lithium polymer, anokuminyana okuphezulu kwamandla, i-miniaturization, i-ultra-thin, engasindi, nokuphepha okuphezulu uma kuqhathaniswa namabhethri e-lithium awuketshezi.

Kodwa ukonakala kubuye kube njalo, kulula ukuba nesenzakalo sesigubhu. Izigubhu zebhethri ze-polymer lithium, okubonisa ukuthi ibhethri liphukile, ibhethri lakho kufanele libe ugesi we-polymer lithium. Ibhethri ngaphezu kokushajwa noma ukuchithwa kwezinga lokushisa eliphezulu kungaba kanje.

Ngemuva kokuthi ukushaja sekugcwele, ithiyori idizayinelwe ukumisa ukushaja. Abasebenzisi banganaka kuphela ukucaciswa kokuvikela ngesikhathi sokusetshenziswa. Izinto ezisemqoka njengekhwalithi yebhethri, ukuphathwa kokushaja.

Ngaphambi kokuhlaziya ukunwetshwa kwebhethri ye-lithium ye-polymer kanye nendlela yokulawula, ukwakheka kwebhethri ye-polymer lithium kusetshenziswa. Isakhiwo esiyinhloko sebhethri ye-lithium ye-polymer sihlanganisa izici ezintathu ze-electrode enhle, i-electrode engalungile ne-electrolyte. Ibhethri ye-lithium ebizwa nge-polymer ukuthi okungenani eyodwa noma ngaphezulu kwezakhiwo ezintathu eziyinhloko zisebenzisa izinto ze-polymer njengesistimu yebhethri eyinhloko.

Ohlelweni oluthuthukisiwe lwebhethri ye-polymer lithium, izinto ze-polymer zisetshenziswa ikakhulukazi kuma-positive kanye nama-electrolyte. I-electrode esebenzayo ihlanganisa i-polymer conductive polymer noma inhlanganisela ye-inorganic esetshenziswa ebhethrini elivamile le-lithium, futhi i-electrolyte ingasetshenziswa ku-polymer electrolyte eqinile noma ye-colloidal, noma i-organic electrolyte, ubuchwepheshe be-lithium ion jikelele, i-electrolyte enguketshezi noma ye-colloidal, ngakho-ke idinga ukupakishwa okuqinile kweSecondary ukuze kuhlangatshezwane nakho okwandisa usayizi wezithako ezivuthayo, okwandisa usayizi wezithako ezivuthayo. Ayikho i-electrolyte eyeqile kunqubo ye-polymer lithium ion, ngakho-ke izinzile, futhi kunzima ukubangela izimo eziyingozi ngenxa yokushaja ngokweqile, ukushayisana noma omunye umonakalo, nokusetshenziswa ngokweqile.

Ubukhulu bokushumeka kwe-lithium ion. Lapho ibhethri lishajwa, i-ion ye-lithium ikhishwa ku-electrode eqondile, okubangela ukwanda kwesikhala se-electrode engalungile, futhi ukwanda, ngokuvamile, ukushuba kwebhethri, ukunwetshwa okukhulu kokunwetshwa; Ngesikhathi senqubo yokukhiqiza, njengokuhlakazeka kwe-slurry, i-C / A ihluke kakhulu, ukulawula izinga lokushisa kuthinta ngokuqondile izinga lokunwetshwa kwebhethri.

Ikakhulukazi, amanzi, ngoba i-lithium carbon compounds ephezulu esebenzayo eyenziwe ngokushaja izwela kakhulu emanzini, ngaleyo ndlela kwenzeka ekuphenduleni kwamakhemikhali okunamandla. Igesi ekhiqizwe ukusabela ibangela ukucindezela okuphezulu kubhethri, okwandisa ukuziphatha kokunwebeka kwebhethri. I-polymer soft bag lithium ibhethri flat gas capsule ihlobene nekhwalithi yebhethri ye-lithium, indlela, imvelo, njll.

1. Iphakheji embi: umswakama womoya ohlelweni lokukhiqiza ungene ngaphakathi kwebhethri, okubangela ukuthi i-electrolyte ibole igesi. 2.

Okuqukethwe kwezintambo zikagesi kweqa izinga: Enqubeni, uma okuqukethwe kwamanzi kweqa izinga, i-electrolyte izohluleka ukukhiqiza igesi. 3. Ukugqwala: I-polymer ethambile yesikhwama se-lithium yebhethri core inokugqwala, isendlalelo se-aluminium siyasabela, silahleka ngenxa yokuvinjwa kwamanzi, okucatshangelwayo.

4. Ukulimala kwendawo: umonakalo wonakele, ukubhoboza umswakama ukuze ungene ngaphakathi kwebhethri. Ngaphezu kwalokho, izici zamakhemikhali zezinto ze-lithium ziyaphila kakhulu, okuletha ingozi ephezulu kakhulu.

Lapho insimbi ye-lithium ivezwa emoyeni, izokhiqiza ukusabela okunamandla kwe-oxidation nge-oxygen. 5. Okuphukile: Impahla ye-Aluminium kulula ukuyikhubaza, kancane, uma ibhethri lilikhulu, isikhwama somoya sikhulu, silimaza kalula.

6. Isifunda esifushane: imiphumela yokuxhumana eqondile nengalungile kumjikelezo omfushane, ibhethri ye-lithium ye-polymer inembile ngisho nentuthu. 7.

Isifunda esifushane sangaphakathi: i-polymer lithium ibhethri isolation membrane shrinkage, curl, umonakalo, ifilimu ye-burr puncture, njll., ingabangela ukunqanyulwa kwangaphakathi, ukuze isikhwama sesigubhu. 8.

Ukushajwa ngokweqile, ukukhiqizwa ngokweqile: Ibhethri lesikhwama esithambile se-polymer lishajwe ngokweqile noma liyagqagqana, futhi ipuleti lokuvikela alivamile, futhi umgogodla webhethri uzophuma ngamandla. Isixazululo sephakheji ye-polymer lithium yebhethri yesigubhu 1. Uma ibhethri likamakhalekhukhwini lishajwa, sebenzisa umunwe kuqala ukuze uthole igebe lebhethri, ngembobo encane izobhoboza imbobo encane, vumela umoya uphele.

2. Faka esikhundleni sephakethe lebhethri le-polymer lithium elisha. Phakathi nenqubo yokushaja, kufanele igwenywe, engavikela ibhethri ekulimaleni, nokonga amandla kanye nemvelo.

Abakhiqizi bebhethri ye-lithium kufanele balawule ngokuqinile umswakama, balawule inqubo yenzuzo kanye nesikhathi sokubhaka kanye nezinga lokushisa. Umsebenzisi uthola ukuthi isigubhu sephakethe lebhethri le-lithium kufanele siyeke ukusebenzisa, ukuthatha izithombe, noma ividiyo endlini, ngaphandle kwalokho umhleli womkhiqizo angase angayiboni i-akhawunti. Ungatshela abantu abaseduze kwakho, uthenge izinto, kufanele uhlale, umkhiqizo uphukile ukuze uthathe ubufakazi.

Isigubhu sebhethri se-polymer lithium sesivele siyinkinga enkulu, akunconywa ukuyisebenzisa. Kungase kube umphumela we-short circuit, fever, intuthu, ukusha, njll. Amabhethri e-lithium anezidingo eziqinile zamashaja, futhi awakwazi ukusebenzisa ukunikezwa kwamandla ukushaja ukunikezwa kwamandla.

Qiniseka ukuthi usebenzisa ishaja enikelwe ibhethri le-lithium. Uma ishaja esetshenzisiwe ingahlangabezani nezidingo, i-polymer lithium battery drum , Kukhona ingozi yokuphepha, ngisho nokuqhuma kungenzeka. Amabhethri e-lithium e-polymer avame ukusetshenziswa ku-MP3, amaphilisi ahlakaniphile, anentuthuko kubuchwepheshe bebhethri, aqinisa lesi simo ngesikhathi sokusebenzisa, futhi ngokuyisisekelo enza izinkinga ezingenzeka.

Isigubhu sebhethri siyinkinga evamile kakhulu. Ngemva kokubhekana nesimo esinjalo, ikhambi elingcono kakhulu ukushintsha amabhethri amasha.
