Iveza imiphetho ye-wavy yama-electrode ebhethri ye-lithium

Esikhathini sanamuhla sokuthuthuka okusheshayo kwezobuchwepheshe, amabhethri e-lithium, njengomthombo wamandla wezinto eziningi zikagesi, asebenza kahle nekhwalithi. Kodwa-ke, into ebonakala ingenamsebenzi engase ibangele izinkinga ezinkulu-ama-wavy ama-electrode ebhethri ye-lithium-ithinta buthule ukusebenza kwamabhethri.

I. Ayini amaphethelo amagagasi ama-electrode ebhethri ye-lithium?

Imiphetho enamagagasi yama-electrode ebhethri ye-lithium ibhekisela ekuguquguqukeni okungajwayelekile kwe-wavy emaphethelweni ama-electrode, angasekho esimweni esiyisicaba. Lo mkhawulo ongalingani akuyona nje indaba yokuthinta ukubonakala kwebhethri.
II. Akhiwa kanjani ama-wavy ama-electrode?

1. Izinto ezibonakalayo: Izici ezibonakalayo zama-electrode ebhethri ye-lithium zibaluleke kakhulu. Uma ukucindezelwa kwesivuno kunganele noma kusatshalaliswa ngokungalingani, kulula ukukhubaza uma sekufakwe amandla angaphandle ngesikhathi senqubo yokukhiqiza, bese kuvela imiphetho yamagagasi. Isibonelo, ezinye izinto zingase zibe nezakhiwo ezimbi zemishini ngenxa yokwakheka okungaphelele noma izinqubo zokulungiselela ezinganembile futhi azikwazi ukumelana ngokuphumelelayo namandla angaphandle.
2. Izinkinga zezisetshenziswa: Ukunemba nokuzinza kwemishini yokukhiqiza ama-electrode ebhethri ye-lithium kunquma ngokuqondile ikhwalithi yama-electrode. Ukunemba okunganele kwe-coater kuzoholela ekuhlanganisweni kwe-slurry engalingani. Ukucindezela kwe-roll okungalingani komshini wokunyathelisa kuzodala ukucindezeleka okungaguquki kuma-electrode. Ukugqoka kwamathuluzi kwe-slitter kungase kuholele emiphethweni engalingani. Lezi zinkinga zingase zibangele imiphetho ye-wavy yama-electrode.
3. Inqubo yokuhlanganisa nokomisa: Phakathi nenqubo yokumboza, uma ijubane lokumboza nokuqina kwe-slurry kungalawulwa kahle, noma uma izinga lokushisa nesivinini somoya kungalingani ngesikhathi sokumiswa, ukusatshalaliswa kokucindezeleka kwangaphakathi kwama-electrode kuzobe kungalingani, kubeka izingozi ezifihliwe. kokuvela okulandelayo kwemiphetho yamagagasi.
4. Ubukhulu be-electrode obungalingani: Ukujiya kwe-electrode okungahambisani kuzodala ingcindezi ehlukene nezimo zokuwohloka ezingxenyeni ezizacile neziminyene ngesikhathi sokucubungula nokusetshenziswa, futhi kulula ukukhiqiza imiphetho yamagagasi. Isibonelo, kwezinye izixhumanisi zokukhiqiza, ukuhluka kokuqina kwe-electrode kungase kwenzeke ngenxa yokulungiswa kwemishini engafanele noma imingcele yenqubo engazinzile.

III. Imiphi imithelela elethwa ama-wavy ama-electrode?

1. Ukushaja okukhinyabezekile nokusebenza kokukhipha: Amaphethelo angamagagasi onqenqema lwe-electrode azoholela ekusabalaleni okungalingani kwamanje endaweni ye-electrode. Ngesikhathi sokushaja, umthamo wendawo ngokweqile ungase ubangele i-lithium plating; phakathi nokukhipha, indawo yamanje yokugxilisa ingqondo ingase ifinyelele kugesi onqanyuliwe ngaphambi kwesikhathi, ngaleyo ndlela yehlise umthamo kanye nokuphuma kwamandla ebhethri. Cabanga ukuthi ifoni yakho ephathekayo ingase ibe nezinkinga ezifana nesivinini sokushaja esihamba kancane kanye nokushisa okukhulu ngesikhathi ishaja, futhi ingase iphelelwe amandla kungazelelwe ngesikhathi sokuyisebenzisa. Konke lokhu kubangelwa imiphetho engamagagasi yama-electrode.
2. Impilo yomjikelezo efinyeziwe: Ingcindezi yangaphakathi engalingani ebangelwa ama-wavy edge iyanqwabelana futhi iqiniswe ngokuqhubekayo phakathi nenqubo yokushaja ephindaphindiwe kanye nenqubo yokukhipha ibhethri, okuholela ekucekeleni phansi kwesakhiwo se-electrode kanye nokuchithwa kwezinto ezisebenzayo. Lokhu kufana nomjikelezo ononya owenza buthaka ngokuqhubekayo ukusebenza kwebhethri futhi ufinyeze kakhulu ukuphila kwayo.
3. Ukwenyuka kwezingozi zokuphepha: Amaphethelo e-electrode angalingani azobangela ukusabalaliswa kwengcindezi okungalingani ngaphakathi kwebhethri, okungase kubangele izinto ezingavamile njengokunwetshwa kwebhethri nokufinyela. Ezimweni ezimbi kakhulu, kungase kubangele ngisho nezinkinga zokuphepha ezifana nama-short circuits kanye ne-thermal runaway, kube usongo ezimpilweni zethu nasezimpahleni zethu.
4. Ukuncipha kwamandla nokwanda kokungazweli kwangaphakathi: Amaphethelo amagagasi ama-electrode azothinta indawo esebenzayo yama-electrode kanye nokufana kokusabela kwe-electrochemical, ukunciphisa umthamo webhethri. Ngesikhathi esifanayo, ukusabalalisa okungalingani kwamanje kuzophinde kwandise ukumelana kwangaphakathi kwebhethri futhi kunciphise ukusebenza kwamandla nokusebenza kahle kwebhethri. Lokhu kusho ukuthi idivayisi yakho ingaba nempilo yebhethri emifushane kanye nesivinini sokusebenza esinensa.

IV. Indlela yokuxazulula inkinga yama-wavy edges of electrode?

1. Khetha izinto ngokuhlakanipha: Khetha izinto ezinezici ezinhle zomshini kanye nesakhiwo esincane esifanayo. Ngokuthuthukisa ukwakheka kwezinto ezibonakalayo kanye nenqubo yokulungiselela, thuthukisa ukucindezeleka kwesivuno kanye nokufana kwempahla ye-electrode. Kufana nokudala isivikelo esiqinile ukuze ibhethri lithuthukise ikhono layo lokumelana nokonakala.
2. Lawula ngokuqinile ukujiya: Phakathi nenqubo yokulungiselela ama-electrode, sebenzisa ukunemba okuphezulu, ukucindezelwa kwe-roll nezinye izinto zokusebenza nezinqubo, futhi uqaphe futhi ulungise ukujiya kwama-electrode ngesikhathi sangempela ukuze uqinisekise ukuvumelana kwawo ngaphakathi kwebanga lamaphutha elivumelekile. Lokhu kufana nokwenza ijazi elilingana kahle lebhethri ukuze kuqinisekiswe ukusebenza kwalo okuzinzile.
3. Ukugcinwa kwezisetshenziswa kanye nokwenza kahle kwenqubo: Gcina njalo futhi ulinganise impahla yokukhiqiza ukuze uqinisekise ukunemba nokuzinza kwemishini. Ngasikhathi sinye, thuthukisa amapharamitha wenqubo njengejubane lokumboza, izinga lokushisa lokumisa, nokucindezela kokucindezela okuqengqelekayo ngokuya ngezimpawu zento ebonakalayo nezidingo zomkhiqizo. Kuphela ngokwenza okokusebenza kanye nenqubo kubambisane ngokuphelele kungancipha ukwenzeka kwama-wavy emaphethelweni ama-electrode.
4. Lungisa inqubo: Lungiselela izinga lokugeleza kwe-slurry, igebe lokumboza kanye nokulawula ukungezwani phakathi nenqubo yokumboza ukuze uqinisekise ukusatshalaliswa okufanayo kwe-slurry endaweni ye-electrode futhi ugcine ibhalansi yokucindezeleka phakathi nenqubo yokomisa. Enqubweni yokucubungula elandelayo, lawula ngokunengqondo ukungezwani kwe-electrode ukuze ugweme ukuguquguquka okubangelwa ukungezwani okungafanele.
5. Inqubo ye-hot roll kanye nokulawula isivinini sokucindezela i-roll: Inqubo ye-hot roll ingathuthukisa izakhiwo ezibonakalayo kanye nokucaba kwendawo yama-electrode. Ngokulawula isivinini sokucindezela i-roll nezinga lokushisa, ukunqwabelana kwengcindezi kanye nokuguqulwa kwama-electrode ngesikhathi senqubo yokucindezela umqulu kungancishiswa ukuze kwakhelwe ama-electrode ayisicaba futhi abushelelezi ebhethri.

V. Indlela yokuthola nokulawula imiphetho yamagagasi yama-electrode?

1. Ukutholwa kwesibonakhulu esibonakalayo: Lena indlela evame ukusetshenziswa yokuhlonza, engabuka ngokunembile i-microscopic morphology yamaphethelo e-electrode futhi yenze ukuhlolwa kokuqala kwezinga nezici zama-wavy edge. Nakuba ukunemba kokutholakala kunqunyelwe, kungasetshenziswa njengendlela yokuhlola ngokushesha.
2. Isixazululo se-microscope yedijithali: Imakroskopu edijithali ehlanganiswe nobuchwepheshe obuthuthukisiwe bokucubungula izithombe inikeza ukukhuliswa okuphezulu nezithombe ezicacile, futhi ingakwazi ukubona nokukala ngokunembe kakhudlwana usayizi, ukuma nokusatshalaliswa kwama-wavy emaphethelweni ama-electrode. Vumela amaphutha amancane angabi nandawo yokucasha.
3. Setha ngokunengqondo amapharamitha wokusika: Setha imingcele enengqondo njengokucindezela kwezinhlangothi kanye nenani lokugqagqana kwethuluzi phakathi nenqubo yokusika ukuze ulawule ukuwohloka kwe-electrode phakathi nenqubo yokusika. Ngesikhathi esifanayo, khetha i-engeli yokuluma efanele, ububanzi beblade kanye nogqinsi lweshidi ukuze unciphise umthelela wokusika ikhwalithi yomkhawulo wama-electrode.

Ngamafuphi, imiphetho ye-wavy yama-electrode ebhethri ye-lithium iyindaba eyinkimbinkimbi futhi ebalulekile ehlanganisa izici eziningi ezifana nezinto zokwakha, okokusebenza, nezinqubo. Kuphela ngokuqonda ngokugcwele izimbangela zayo nemithelela nokuthatha izinyathelo zokuthuthukisa ezisebenzayo nezindlela eziqinile zokutholwa nezindlela zokulawula lapho kungathuthukiswa ikhwalithi yama-electrode ebhethri ye-lithium, bese ukusebenza kukonke nokuthembeka kwamabhethri e-lithium kungathuthukiswa. Ake sinake inkinga yama-wavy emaphethelweni ama-electrode ebhethri ye-lithium ndawonye futhi siphelezele ukusebenza okuzinzile kwamadivayisi kagesi kanye nokuphepha kwempilo yethu.
