Zeziphi iindlela zokulinganisa “kancinci kancinci” isixa senaliti ye-electrolyte yeebhetri ze-lithium? Ukusebenza kweebhetri ze-lithium ion kuhambelana kakhulu ne-electrolyte, kwaye inani le-electrolyte linempembelelo enkulu ekusebenzeni kwebhetri ye-electrochemical kunye nokhuseleko. Umthamo wenaliti efanelekileyo ye-electrolyte ayisiyoncedo kuphela ukwandisa uxinano lwamandla kunye nokunciphisa iindleko, kodwa ikwadlala indima ebalulekileyo ekuphuculeni ubomi bomjikelo weebhetri ze-lithium.

Zeziphi iindlela zokufumanisa umthamo weenaliti ze-lithium “zincinci kancinci”?

Kuba i-electrolyte izakuqhubeka nokufumana i-oxidation kunye nokunciphisa ukusabela kwii-electrode ezilungileyo nezingalunganga ngexesha lokusebenza kwebhetri ye-lithium, umthamo omncinci kakhulu wenaliti uyingozi kubomi bomjikelo webhetri ye-lithium ion. Kwangelo xesha, ukuba isixa se-electrolyte sincinci kakhulu, oko kuya kubangela ukuba ezinye izinto ezisebenzayo zingangeni, ezingalunganga kuphuhliso lomthamo webhetri ye-lithium. Nangona kunjalo, umthamo omkhulu wenaliti uya kubangela iingxaki ezinje ngokuncipha koxinano lwamandla eebhetri ze-lithium ion kunye nokunyuka kweendleko. Ke ngoko, indlela yokujonga ubungakanani benaliti efanelekileyo ekusebenzeni nasekusebenzeni kweebhetri ze-lithium. Ibhalansi phakathi kweendleko ibaluleke ngokukodwa.

“Kancinci kancinci, kuncinci, kwaye kuncinci kakhulu” umthamo we-injection ye-electrolyte yeebhetri ze-lithium isitatimende esiqhelekileyo, kwaye akukho mfuneko engqongqo. Nokuba i-electrolyte incinci kancinane, ibhetri ye-lithium sele iyimveliso enesiphene. Iiseli ezine-electrolyte encinci encinci akukho lula ukuba zifumaneke. Ngeli xesha, amandla kunye nokumelana kwangaphakathi kweeseli kuyinto eqhelekileyo. Zintathu iindlela zokufumanisa ukuba ibhetri ye-lithium ine-electrolyte encinci. .

1. Susa ibhetri

Ukuqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqweni lokuvavanya ukutshabalalisa kwaye iseli enye kuphela inokuvavanywa ngexesha. Nangona ingxaki inokumiselwa ngokuchanekileyo nangokuchanekileyo, eyona ndlela yokusetyenziswa kwale ndlela ukukhusela iiseli ngokungeyomfuneko.

2. Ukujonga ubunzima

Ukuchaneka kwale ndlela kusezantsi, kuba isiqwenga sepali, ifilimu yeplastiki ye-aluminium, njl njl. Kuba i-electrolyte yebhetri ye-lithium “incinci kancinci”, emva koko ukugcinwa kweseli nganye yebhetri ngekhe kwahluka kakhulu. , Ke umahluko wobunzima bezinye izinto kunokwenzeka ukuba ube mkhulu kunomahluko kubunzima be-electrolyte.

Ewe unokwazi ngokuchanekileyo nangexesha elifanelekileyo iseli lengxaki ngokulinganisa ubungakanani bolwelo okanye ubungakanani bolwelo olugcinwe yiseli nganye ngexesha lenaliti yolwelo, kodwa endaweni yokulinganisa iseli epheleleyo, kungcono ukwandisa ukuchaneka kunye nokwandisa inkqubo ukunyanga iimpawu kunye nonobangela.

3. Uvavanyo

Le yeyona nto kugxilwe kuyo umbuzo. Luhlobo luni lwendlela yovavanyo enokusetyenziselwa ukukrola iiseli nge-electrolyte “encinci”, elingana nohlobo luni lokungaqhelekanga oluya kubakho kwiiseli ezine-electrolyte “encinci”. Okwangoku, zimbini kuphela iindlela ezaziwayo ukulinganisa iiseli ezinomthamo oqhelekileyo kunye nokumelana kwangaphakathi, kodwa nge-electrolyte encinci. Ezi ndlela zimbini zezi: umjikelo, iqonga lokukhutshwa kwenqanaba.

Ngaba ifuthe lokwenza umthamo weebhetri ze-lithium kukusebenza njani?

InfluenceImpembelelo yevolthi ye-electrolyte kumthamo webhetri ye-lithium

Umthamo weebhetri ze-lithium zanda njengoko umxholo we-electrolyte unyuka. Owona mthamo ubalaseleyo weebhetri ze-lithium kukuba isahluli siya kuzika. Kuyabonakala ukuba isixa se-electrolyte asonelanga, ipleyiti efanelekileyo ye-electrode ayinamanzi ngokupheleleyo, kwaye isahluli asifakwanga, nto leyo ekhokelela kukunganyangeki okukhulu ngaphakathi kunye nomthamo ophantsi. Ukunyuka kwe-electrolyte kulungele ukusebenzisa ngokupheleleyo amandla emathiriyeli esebenzayo. Oku kubonisa ukuba umthamo webhetri ye-lithium unolwalamano olukhulu nesixa se-electrolyte. Umthamo weebhetri ze-lithium zonyuka ngenani le-electrolyte, kodwa ekugqibeleni zihlala zingaguquguquki.

②Impembelelo yevolthi ye-electrolyte ekusebenzeni komjikelo webhetri ye-lithium

I-electrolyte incinci, i-conductivity iphantsi, kwaye ukuxhathisa kwangaphakathi kwanda ngokukhawuleza emva kokuhamba ngebhayisikili. Ukukhawulezisa ukubola okanye i-volatilization ye-electrolyte encinci yebhetri ye-lithium liqondo apho umjikelo wokusebenza kwebhetri uncipha. Ubuninzi be-electrolyte buya kukhokelela ekuphenduleni kwecala kunye nokwanda kwimveliso yegesi, okubangela ukuhla kwintsebenzo yomjikelezo. Ngapha koko, i-electrolyte eninzi ichithwe. Kuyabonakala ukuba isixa se-electrolyte sinefuthe elibonakalayo ekusebenzeni komjikelo webhetri ye-lithium. Incinci okanye i-electrolyte encinci ayilungelanga ukusebenza komjikelo webhetri.

③Impembelelo yevolumu ye-electrolyte ekusebenzeni kukhuseleko lweebhetri ze-lithium

Esinye sezizathu zokuqhuma kweebhetri ze-lithium kukuba umthamo wenaliti awunakho ukuhlangabezana neemfuno zenkqubo. Xa inani le-electrolyte lincinci kakhulu, ukuxhathisa kwangaphakathi kwebhetri kukhulu kwaye ukuvelisa ubushushu kukhulu. Ukonyuka kwamaqondo obushushu kuya kubangela ukuba i-electrolyte ibole ngokukhawuleza ivelise igesi, kwaye isahluli sinyibilike, esiya kuthi sibangele ukuba ibhetri ye-lithium idumbise kwaye ifutshane kwaye ijikeleze. Xa isixa se-electrolyte sikhulu kakhulu, isixa segesi esiveliswe ngexesha lokutshaja nokukhupha sikhulu, uxinzelelo lwangaphakathi lwebhetri likhulu, kwaye ityala lophukile, libangela ukuvuza kwe-electrolyte. Xa iqondo lobushushu le-electrolyte liphezulu, liyakubamba umlilo xa lidibana nomoya.

I-Electrolyte isetyenziswa njengendawo yokufuduka kwe-lithium ion kunye nokudluliswa kwentlawulo. Ukuqinisekisa ukusetyenziswa okugcweleyo kwezinto ezisebenzayo, indawo nganye engenanto yesiseko sebhetri kufuneka izaliswe nge-electrolyte. Ke ngoko, umthamo wendawo yangaphakathi webhetri unokusetyenziselwa ukumisela ngokufanelekileyo ibhetri yebango le-electrolyte. ubungakanani. Kuyabonakala ukuba isixa se-lithium yebhetri ye-electrolyte inefuthe elibonakalayo ekusebenzeni komjikelo webhetri. Ubuninzi okanye i-electrolyte encinci kakhulu ayihambelani nokusebenza komjikelo webhetri ye-lithium.
