Ibhetri ye-lithium yobushushu obubanzingokubanzi ibhekisa kubushushu obuphezulu beebhetri ze-lithium-ion, ke ukuba uqhushumbo lwenzeka ngexesha lokusetyenziswa, luya kuba naliphi ifuthe kwibhetri?Siyazi ukuba iseli yebhetri ihlala i-ternary lithium ibhetri.Kwaye ngoku kukho iiseli ezininzi ezahlukeneyo, ezifana ezinye iibhetri zethu eziqhelekileyo ternary lithium kusetyenziswa electrode graphite negative, olu hlobo izinto ngenxa electrode negative, iibhetri eziziiprayimari lithium kusetyenziswa izinto lithium cobaltate ngenxa electrode elungileyo.Ke ibhetri ye-lithium ebanzi yobushushu iya kudubula phantsi kobushushu obuphezulu obuzinzileyo?Apha ukwabelana nawe ngezimvo ezifanelekileyo.
Njengoko izinto ezisetyenziswa kwiiseli zebhetri zangoku, kubandakanywa iibhetri ze-lithium-ion ze-lithium cobaltate, i-lithium iron phosphate kunye nezinye izinto zokwenza i-electrode efanelekileyo.Ke ibhetri ye-ternary ye-lithium kubushushu obuphantsi xa amathuba okuqhuma kuncinci kakhulu.Kodwa uninzi lwentengiso yangoku yeebhetri ze-lithium ezibanzi ziya kusebenzisa i-lithium cobaltate njenge-electrode elungileyo.Kwaye i-lithium iron phosphate isekelwe kwi-lithium ye-ternary ukwenza i-electrode embi;kunye ne-lithium cobaltate kukwenza i-electrode efanelekileyo;kunye ne-ternary lithium ion kukwenza i-electrode engalunganga kunokuba i-electrode efanelekileyo.Oku kukhokelela kutshintsho kwisakhiwo sebhetri yayo.
Ukusombulula ingxaki yokhuseleko lweebhetri ze-lithium ezibanzi zobushushu, undoqo kukuphucula ukhuseleko.Okokuqala, iseli yebhetri kufuneka ilawulwe ngokungqongqo, nto leyo ekwasisiqinisekiso sokusebenza kwebhetri kwaye inokuphepha ngokufanelekileyo isiphaluka esifutshane sangaphakathi okanye i-overcharge ngexesha lokusebenza kwebhetri, kunye nokuthintela ukwenzeka kobushushu bangaphakathi bebhetri. , okubangela ukuqhuma kwebhetri.Kwaye ekusetyenzisweni kwemihla ngemihla kufuneka kwakhona ingqalelo kubomi obukhuselekileyo bebhetri kwaye ugweme ukufudumala kwebhetri, ukutshaja ngokugqithiseleyo kunye nezinye iimeko.Okulandelayo, kufuneka sinikele ingqalelo kwimpembelelo yobushushu kwibhetri.Iqondo lobushushu bebhetri liphezulu kakhulu ukuba singakhuseleka kubomi bethu nalo liya kuba sisoyikiso.Ngoko ke, ukuba iimveliso zebhetri zifuna ukusetyenziswa ngcono kubomi bethu bemihla ngemihla, kufuneka sinikele ingqalelo kumsebenzi wokulawula ubushushu bebhetri.
Ukusuka kwindawo yokujonga ukhuseleko, xa ubushushu bebhetri buphezulu kakhulu, iibhetri ze-lithium-ion zinokuthi zenzeke i-thermal runaway combustion phenomenon.Oku kungenxa yokuba i-ion ye-lithium equlethwe kwibhetri ye-lithium-ion ubukhulu becala yenziwe ngamathontsi angamalwelo, kokukhona amathontsi angamalwelo amaninzi, kokukhona ubushushu bebhetri ye-lithium-ion buphezulu, ukuba i-ion ye-lithium kwi-electrolyte ifuduka ngokugqithisileyo, ukusasazwa kuya kwenza I-lithium ion imfuduko engaguqukiyo ekhokelela kwibhetri emfutshane-yesekethe ukutsha okuzenzekelayo, njl.njl Umlilo webhetri okanye ukuqhuma.Ngoko ke, ukusuka kwindawo yokukhusela, ukusetyenziswa kweebhetri ze-lithium-ion eziphezulu zokushisa kufuneka zicinywe ngexesha elifanelekileyo.Ukongezelela, ukuba iqondo lokushisa liphezulu kakhulu, kulula ukubangela ukujikeleza okufutshane kwangaphakathi kwaye ngaloo ndlela kubangele umlilo kunye nokuqhuma.Ukongezelela, ukusuka kwindawo yokukhusela ibhetri yamandla, ukuba akukho ukuhlolwa okubanzi kokhuseleko kunye nokusetyenziswa kwe-thermal runaway state yebhetri ye-lithium-ion inokuthi iqhume.
Enyanisweni, ibhetri ye-lithium yokushisa ebanzi ikhuselekile ukuyisebenzisa kuba ihlangabezana neemfuno zokhuseleko lweebhetri ze-lithium-ion kwi-GB18483-2001 iNkcazo yoBugcisa boKhuseleko kwiiBatri zeLithium-ion, ezihambelana ngakumbi nemigangatho yokhuseleko.Kodwa ngenxa yokuba imveliso entsha, akukho migangatho ecacileyo yelizwe kunye nemigangatho yoshishino ukukhokela ukuphuhliswa kobu buchwepheshe, ngoko kufuneka sidibanise ukusetyenziswa kokuqonda okuthile.Kwinkqubo yokusetyenziswa kufuneka ugweme ukudibanisa nokushisa okuphezulu, umbane we-static, ukukhutshwa, ukukhutshwa kunye nezinye izinto ezinobungozi, ngaphandle koko kulula ukubangela ukuqhuma okungundoqo.Ke ekusetyenzisweni kwemihla ngemihla kufuneka ingqalelo ekusetyenzisweni okukhuselekileyo kwebhetri ye-lithium ebanzi kunye nokugcinwa okukhuselekileyo kunye nokusetyenziswa.
Oku kungasentla malunga nokuba ibhetri ebanzi lithium ibhetri iya kugqabhuka kunye nobushushu ebanzi lithium ibhetri umxholo enxulumene.
