1. Sebenzisa i-electrolyte ekhuselekileyo ye-lithium ibhetri okwangoku i-lithium ibhetri ye-electrolyte usebenzisa i-carbonate njenge-solvent, apho i-carbonate ye-linear inokuphucula ukuhlawulwa kunye nokukhupha umthamo webhetri, kodwa i-flash point yabo iphantsi, kwiqondo lokushisa eliphantsi liya kukhanya, kwaye I-solvent ye-fluoro ine-flash point ephezulu okanye akukho flash, ngoko ke isinyibilikisi se-fluoro sisetyenziselwa ukucinezela ukutsha kwe-electrolyte. Okwangoku izinyibilikisi zefluoride ezifundiweyo ziquka i-fluoroate kunye ne-fluoroethyl ether.
I-electrolyte ye-flame retardant yi-electrolyte esebenzayo ukuba umsebenzi we-flame retardant we-electrolyte enjalo udla ngokufunyanwa ngokudibanisa i-additive retardant edibeneyo kwi-electrolyte eqhelekileyo. I-electrolyte ye-flame-retardant okwangoku isombulula awona manyathelo anoqoqosho kwaye asebenzayo kukhuseleko lwebhetri ye-lithium, ngakumbi ngokuxhomekeke kushishino. Ukusebenzisa i-electrolytes eqinile, endaweni ye-electrolyte ye-organic fluid, iphucula ngokufanelekileyo ukhuseleko lweebhetri ze-lithium.
Ii-electrolyte eziqinileyo ziquka i-electrolyte eqinileyo ye-polymer kunye ne-electrolyte eqinileyo ye-inorganic. I-electrolyte yepolymer, ngakumbi i-gel-type polymer electrolyte, yenziwe kakhulu kwibhetri ye-lithium yorhwebo, kodwa i-electrolyte ye-polymer ye-gel eneneni i-electrolyte yepolymer eyomileyo kunye ne-electrolyte compromise. Ngenxa yoko, iyancipha kakhulu ekuphuculeni ukhuseleko lwebhetri.
Ngenxa ye-electrolyte ye-polymerization yesimo esomileyo, ekubeni ayifani ne-gel-type polymer electrolyte, inokhuseleko olungcono malunga nokuvuza, uxinzelelo lomphunga kunye nokutsha. Okwangoku, i-aggregate electrolyte yangoku ayihambelani neemfuno zesicelo se-polymer lithium ibhetri, kwaye uphando olongezelelweyo kulindeleke ukuba lusetyenziswe ngokubanzi kwiibhetri zokugcina i-polymer lithium. I-electrolyte yepolymer enxulumene nesigaba, i-electrolyte eqinileyo ye-inorganic inokhuseleko olungcono, akukho volatilization, akukho ukutsha, akukho ngxaki yokuvuza.
Ngaphezu koko, amandla omatshini we-electrolyte eqinileyo ye-inorganic iphezulu, iqondo lobushushu elikwaziyo ukumelana nobushushu liphezulu kakhulu kunolo lwe-electrolyte engamanzi kunye ne-organic polymer, lwandise ubushushu bokusebenza kwebhetri; i-inorganic material yenziwa ifilimu, ekunokwenzeka ukuba ifezekise ibhetri ye-lithium miniaturization, kwaye olu hlobo lwebhetri lunobomi bokugcina be-Ultra-long bunokwandisa kakhulu intsimi yesicelo seebhetri ze-lithium ezikhoyo. 2. Ukuphucula ingxaki yokhuseleko lwe-thermostability yezinto ze-electrode zibangelwa ngokuthe ngqo yi-electrolyte engakhuselekanga, kodwa kwi-root cause, kuba ibhetri ngokwayo ayiphezulu, ukuvela kwe-thermal ngaphandle kolawulo kubangelwa.
Ukongeza ukuzinza thermal le electrolyte, uzinzo thermal le electrolyte kwakhona sesinye sezizathu ezibalulekileyo, ukuze uzinzo thermal izinto electrode nayo inxalenye ebalulekileyo yokuphucula ukhuseleko ibhetri, kodwa electrode. ekhankanywe apha Ukuzinza kwe-thermal yezinto eziphathekayo akubandakanyi nje ukuzinza kwayo kwe-thermal, kodwa kubandakanya ukuzinza kwe-thermal yezinto ze-electrolyte. Ngokuqhelekileyo, ukuzinza kwe-thermal yezinto ezimbi ze-electrode kuchongwa ngumsebenzi wesakhiwo sezinto eziphathekayo kunye ne-electrode embi yokutshaja. Ngokubhekiselele kwizinto zekhabhoni, izinto zekhabhoni ezijikelezayo, ezifana ne-carbon microspheres ephakathi (MCMB), kunye nomlinganiselo ophantsi, umrhumo ophezulu kunye neqonga lokukhupha, ngoko ke imeko yayo yokutshaja incinci, kwaye ukuzinza kwe-thermal kuthelekiswa.
Kuhle, ukhuseleko oluphezulu. I-Li4Ti5O12 yesakhiwo se-spinel singcono kunozinzo lwesakhiwo se-graphite elaminated, kwaye iqonga lokuhlawuliswa kunye nokukhutshwa liphezulu kakhulu, ngoko ukuzinza kwe-thermal kungcono kwaye ukhuseleko luphezulu. Ke ngoko, i-MCMB okanye i-Li4Ti5o12 idla ngokusetyenziswa kumandla e-lithium-ion ibhetri yeemfuno zokhuseleko ukutshintsha igraphite eqhelekileyo njenge-electrode engalunganga.
Ukongeza kwizinto ngokwazo, ukuzinza kwe-thermal yezinto ezingalunganga ze-electrode zixhalabele ngakumbi malunga nokuzinza kwe-thermal ye-electrolyte inwebu eqinileyo (SEI) ye-interface engalunganga ye-electrolyte interface ye-electrolyte interface, ehlala isetyenziswa yinto efanayo, igraphite ethile. Cinga ukuba linyathelo lokuqala kwisehlo sokulahleka kobushushu. Kukho iindlela ezimbini ezibalulekileyo zokuphucula ukuzinza kwe-thermal yefilimu ye-SEI: enye i-coating surface yezinto ezimbi ze-electrode, ezifana nokugubungela i-amorphous charcoal okanye i-metal layer phezu kwegraphite; enye kukongeza izongezo zokwenza ifilimu kwi-electrolyte, kwibhetri Ngexesha lenkqubo yokuvula, benza ifilimu ye-SEI enozinzo lwezinto ze-electrode, enenzuzo ekufumaneni ukuzinza okungcono kwe-thermal.
