Ukuvavanya ubungakanani bebhetri ye-lithium-ion isisombululo se-electrolytic "kancinci ngaphantsi"? Ukusebenza kwebhetri ye-lithium-ion kunobudlelwane obusondeleyo kunye ne-electrolyte, kwaye inani le-electrolyte linempembelelo enkulu kwi-electrochemical kunye nokhuseleko lwebhetri. Inaliti ye-electrolyte efanelekileyo yolwelo ayincedi kuphela ekuphuculeni ubuninzi bamandla kunye neendleko ezincitshisiweyo, kodwa ikwangumbandela wokuqwalaselwa kweebhetri ze-lithium-ion. Yeyiphi indlela "encinci encinci" yokuvavanya ubungakanani bebhetri ye-lithium ion isisombululo se-electrolytic? Ekubeni i-electrolyte iya kuqhubeka i-oxidize kwaye iphendule kwi-electrode efanelekileyo kunye ne-negative ngexesha lebhetri ye-lithium ion, ubungakanani bolwelo luncinci kakhulu.
Ubomi bomjikelo webhetri ye-ion ayithandeki, kwaye ukuba inani le-electrolyte lincinci kakhulu, ezinye izinto ezisebenzayo azikwazi ukungeniswa, kwaye ngoko ke akuhambisani nokusebenza kwebhetri ye-lithium-ion, kodwa ubungakanani bolwelo. Umxholo uya kubangela ukuba ubuninzi bamandla ebhetri ye-lithium ion bunciphe. Indlela yokunyusa iindleko, ngoko indlela yokumisela ubungakanani bolwelo, kunye nebhalansi phakathi kweebhetri ze-lithium-ion ekusebenzeni kunye neendleko kubaluleke kakhulu. Ubungakanani bebhetri ye-lithium-ion isisombululo se-electrolytic "kancinci kancinci, ngaphantsi, sinzulu" yinkcazo jikelele, akukho mfuneko engqongqo.
Nokuba kancinci kancinci, ibhetri ye-lithium-ion sele iyimveliso enesiphene. Ulwelo lwe-electrolytic lutshaya kancinci, ekungekho lula ukulufumana. Ngeli xesha, umthamo kunye nokuxhathisa yangaphakathi ibhetri ziqhelekile, kwaye lithium ion ibhetri electrolyte kancinci ibhetri iseli ineentlobo ezintathu zeendlela: ukususa core, umlinganiselo, Ukufunyanwa.
1. Ukwahlula i-core yinkqubo eyonakalisayo kwaye inokuvavanya kuphela ibhetri ngexesha, nangona inokuba yinto enembile kwaye igqitywe ngokuchanekileyo, kodwa ngokwenene sebenzisa le ndlela yokukhusela iziseko zebhetri. 2.
Ukulinganisa le ndlela ayichanekanga kangako, kuba ipali, ifilimu yeplastiki ye-aluminium, njl njl. ibhetri ye-lithium-ion electrolyte "ingaphantsi kancinci", ngoko elona xabiso lepesenti yolwelo nayo Ayinazikhewu, ukuze ezinye izinto zihluke, kunokwenzeka ukuba zibe mkhulu kunomahluko kubunzima be-electrolyte. Ewe kunjalo, kuyenzeka ukulinganisa ubungakanani bomthamo wolwelo okanye ubungakanani bokupheliswa kweseli nganye okanye ubungakanani bokupheliswa kolwelo, kodwa abunamandla njengebhetri iyonke, ayinamandla njengepheleleyo. -cell core.
Kwaye ulungiselele inkqubo,. 3. Ukuphonononga le ngongoma ephambili yengxaki, kwaye luhlobo luni lwendlela yokufumanisa enokukhusela ibhetri ye-electrolyte "incinci encinci", ilingana ne-electrolyte "incinci encinci" iiseli zebhetri ziya ngokungaqhelekanga.
Okwangoku, iindlela ezimbini kuphela ezinokulinganisa umthamo, kwaye ukuchasana kwangaphakathi kuqhelekileyo, kodwa i-electrolyte iphantsi kancinci. Ezi ndlela zimbini zezi: ukukhwela ibhayisekile, iqonga lokukhupha lokukhulisa. Yintoni umphumo wenaliti yolwelo lwe-electrolytic ekusebenzeni kwebhetri ye-lithium ion? 1 Isixa solwelo lwe-electrolytic oluchaphazela umthamo webhetri ye-lithium ion lunyuse umthamo webhetri ye-lithium ion.
Umthamo omkhulu weebhetri ze-lithium-ion kukuba isahluli siya kucwiliswa. Ingabonwa ukuba inani le-electrolyte alanelanga, i-electrode plate ene-positive ayinamanzi amaninzi, kwaye i-diaphragm ayinamanzi, okubangelwa ukuchasana okukhulu kwangaphakathi kunye nomthamo ophantsi. Ukunyuka okutsha kwe-electrolytes kunenzuzo kumthamo wento esebenzayo.
Le nkcazo inobudlelwane obukhulu kunye nomthamo webhetri ye-lithium-ion kunye nesixa se-electrolyte. Umthamo webhetri ye-lithium-ion uyanda ngokunyuka komthamo we-electrolyte liquid, kodwa ekugqibeleni udla ngokuhlala. 2 Isixa solwelo lwe-electrolytic ekusebenzeni okujikelezayo kwebhetri ye-lithium ion incinci, i-conductivity ephantsi yombane, kunye nokuchasana kwangaphakathi kokujikeleza ngokukhawuleza, kwaye uhlalutyo okanye ukuguqulwa kwe-electrolyte yendawo yeebhetri ze-lithium-ion yisantya somjikelezo webhetri. ukusebenza.
Ubuninzi be-electrolyte bunokubangela ukudakumba okutsha ukufumana umthamo omtsha wegesi, okukhokelela ekunciphiseni kokusebenza kokujikeleza kwegazi. Ngaphezu koko, kukho i-electrolyte eninzi kakhulu. Ingabonwa ukuba inani le-electrolyte linempembelelo enkulu ekusebenzeni komjikelezo webhetri ye-lithium ion.
Ukugqithiswa kwe-electrolyte okanye ukusebenza ngokugqithisileyo kwe-dissipative circulation. 3 Umthamo wolwelo we-Electrolytic uchaphazela ukhuseleko lwe-lithium ion ukusebenza kwebhetri yokhuseleko Enye yemvelaphi yebhetri ye-lithium ion kukuba ubungakanani bolwelo alukwazi ukuhlangabezana neemfuno zenkqubo. Xa isixa se-electrolyte sincinci kakhulu, ukuchasana kwangaphakathi kwebhetri kukhulu kwaye ubushushu buphezulu.
Ukunyuka kweqondo lokushisa kunokubangela ukuba i-electrolyte ihlaziywe ngokukhawuleza kwaye igesi yenziwe, kwaye i-diaphragm iya kunyibilika, okubangelwa ukwanda kwebhetri ye-lithium ion kunye nokuqhuma kwexesha elifutshane. Xa isixa se-electrolyte sikhulu kakhulu, isixa segesi esenzeka ngexesha lokutshaja kunye nokukhupha likhulu, uxinzelelo lwangaphakathi lwebhetri lukhulu, kwaye indlu iphukile, okubangela ukuvuza kwe-electrolyte. Xa iqondo lobushushu le-electrolyte liphezulu, liya kubamba umlilo emoyeni.
Isisombululo se-electrolytic sisetyenziselwa ukufuduka kwe-lithium ion kunye nentlawulo yokuqinisekisa ukuba izinto ezisebenzayo zisetyenziswa ngokwaneleyo, zifuna isisombululo se-electrolytic kwindawo nganye engenanto ye-core core, ngoko umthamo wendawo yangaphakathi unokusetyenziselwa kakhulu. misela imfuno ye-electrolyte electrolyte electrolyte. ubungakanani. Ingabonwa ukuba ubungakanani besisombululo se-lithium-ion ibhetri ye-electrolytic ekusebenzeni komjikelo webhetri icacile, i-electrolyte eninzi kakhulu okanye encinci ayihambisani nomjikelo weebhetri ze-lithium ion.
