Intshayelelo:
Okwangoku, kukho ingxaki eqhelekileyo kwisithuthi esitsha samandla kunyeibhetri ye-lithiumiimarike zokugcina amandla, kwaye oko kukoyika ukubanda. Akukho sizathu simbi ngaphandle kweendawo ezinobushushu obuphantsi, ukusebenza kweebhetri ze-lithium kuncipha kakhulu, kubonisa ukulahleka kwamandla amakhulu kunye namandla, ubunzima bokutshaja, njl.njl., okanye ukungaphumeleli ukusebenza ngokufanelekileyo.
Apho kukho iindawo ezibuhlungu, kukwakho namathuba amakhulu ophuhliso. Ibhetri ekhethekileyo yeXingdong Lithium Battery enobushushu obuphantsi yenzelwe "ukubanda". Ngomhla we-8 ka-Agasti, kwiforam ethi "2024 China Energy Storage Industry Ecological Conference" ngomhla woMboniso weHlabathi weBhetri kunye neShishini lokuGcina Amandla ka-2024, iXingdong Lithium Battery yaqalisa iibhetri ezine ezisebenza kakuhle ezinganyangekiyo kubushushu obuphantsi ezinetshaja ephezulu kunye nokusebenza kakuhle kokukhupha ngaphezulu kwe-97%, nto leyo eyalungisa ukusilela kobushushu obuphantsi kweebhetri ze-lithium iron phosphate kwaye yaqinisekisa ukuba iibhetri ze-lithium iron phosphate nazo zinokusebenza ngokuzinzileyo nangokufanelekileyo phantsi kweemeko zemozulu ebandayo.
Ungayoyisa njani ibhetri ye-lithium engaphantsi kobushushu?
"Phantsi kweemeko zobushushu obuphantsi, izinga lokusabela kweekhemikhali ngaphakathi kwebhetri liyehla kwaye isantya sokuhamba kwee-ions kwi-electrolyte siyehla, nto leyo echaphazelaiibhetri ze-lithiumukusebenza kakuhle kokutshaja nokukhupha. Ukongeza, amaqondo obushushu aphantsi anokubangela utshintsho kwisakhiwo sezinto ezingaphakathi kwebhetri, ngaloo ndlela echaphazela ukusebenza kunye nobomi bebhetri." ULi Jia, umongameli weshishini lehlabathi leXingdong Lithium Battery, uthe ukuze kusonjululwe ingxaki yokusebenza kwamaqondo obushushu aphantsi, eyona nto iphambili kukuphuhlisa izixhobo ezinokunyamezela amaqondo obushushu aphantsi.
Ukususela kwizinto ezisetyenzisiweyo nakwezinye iinkalo, i-Xingdong Lithium Battery yoyise ubunzima kwaye iphuhlise ngempumelelo inani leetekhnoloji ezinelungelo elilodwa lomenzi. Ikwavelise ngempumelelo ii-4 eziphantsi kobushushu ngobuninzi.iibhetri ze-lithiumezinokutshajwa kwaye zikhutshwe kwiindawo ezinobushushu obuphantsi be -20℃, -25℃, -30℃, kunye ne -35℃, ezinobubanzi bomthamo obuphakathi kwe-206Ah ukuya kwi-314Ah, kunye nokusebenza kakuhle kokutshaja kunye nokukhupha okungaphezulu kwe-97%, 95%, 95%, kunye ne-90%, ngokulandelelana, zikhokela ishishini.
Ukuba sijonga imfihlo ngokusondeleyo, siya kufumanisa ukuba indibaniselwano yegolide yebhetri ye-Xingdong lithium "4+N" idlale indima ebalulekileyo. I-4 ibhekisa kwiiteknoloji ezine eziphambili, kwaye i-N ibhekisa kwiiteknoloji ezininzi ezinelungelo elilodwa lomenzi ezisetyenziswa ngokudibeneyo:
1. Ngokudityaniswa kwee-carbon nanotubes kunye ne-graphene,ibhetri ye-lithiumImpedance inciphile kakhulu, ukumelana kwangaphakathi yi-≤0.25mΩ, ukusebenza kwesantya kuphuculwe kakhulu, kwaye inokuxhasa i-15C instantaneous discharge current;
2. Itekhnoloji yokugquma i-diaphragm enelungelo lobunikazi iyasetyenziswa ukwenza isiqwenga sepali sinamathele kakhulu ngexesha lokusebenza, nto leyo ephucula ngempumelelo ukhuseleko lwebhetri kunye nokusebenza komjikelo;
3. I-electrolyte yejeli enelungelo lobunikazi ekwi-situ iyasetyenziswa, kwaye i-initiator kunye ne-coagulant ehambelana nebhetri ye-lithium iron phosphate zongezwa ukwenza ibhetri imelane nobushushu obuphantsi, kwaye uluhlu lobushushu bokusebenza kwebhetri lunokufikelela kwi -35℃ ~ 60℃;
4. Inkqubo yokufaka i-stacking iyamkelwa, xa ithelekiswa nenkqubo yokujika yendabuko, ukumelana kwangaphakathi kuncitshiswa ngama-30%, kunye nozinzo olungcono lwesakhiwo, ukhuseleko oluphezulu, ubomi bomjikelo omde, kunye noxinano lwamandla ≥180Wh/kg;
5. Ngeepatenti ezingama-43 zokuyila, inkqubo ye-lithium iron phosphate iyasetyenziswa, idityaniswe neenkqubo ezizodwa, kwaye imveliso ezenzekelayo ngokupheleleyo kunye nemigca yemveliso echanekileyo isetyenziselwa ukuqinisekisa ukuhambelana okuphezulu kweeseli zebhetri, kwaye iya kukhuthaza ukuphuculwa okuqhubekayo kunye nokuphindaphinda kweemveliso.
Impembelelo kwishishini leebhetri ze-lithium
Kwinqanaba lobuchwephesha, uninzi lweebhetri ezikwimarike okwangoku zinokusebenza kwinqanaba lobushushu eliyi--20℃ ~ 60℃, ngelixa iXingdong Lithium Battery iphantsi kobushushu.ibhetri ye-lithiumingasebenza kubushushu obuyi -35℃～60℃, nto leyo eya kuvuselela ukuphuculwa kunye nobuchule betekhnoloji yebhetri yobushushu obuphantsi kwakhona kwaye ithathe ukhokelo;
Kwinqanaba leshishini, iXingdong Lithium Battery ijongene nengxaki yeebhetri ezinobushushu obuphantsi kwaye iqalise iimveliso eziphambili kushishino. Phakathi kwazo, kukho ubushushu obuphantsi obuyi -35℃.ibhetri ye-lithiuminokusebenza kakuhle kokutshaja nokukhupha umbane okungaphezulu kwe-90%, okungeyonto nje kuphela eyenza inzuzo eyahlukileyo, kodwa kuthetha ukuba eli shishini liya kufezekisa amalungelo alinganayo ombane emantla nasezantsi, libe lelinye inqanaba elibalulekileyo kuphuhliso lwetekhnoloji yebhetri;
Kwinqanaba lemarike, enye yemingeni ejongene nezixhobo zomkhosi eziphakamileyo kukuba njengoko ukuphakama kokubhabha kusanda, indawo enobushushu obuphantsi kwindawo enobushushu obuphantsi inokubangela ukuba ukusebenza kwebhetri kwehle; iindawo ezinobushushu obuphantsi ebusika ezifana ne-Inner Mongolia kunye ne-Xinjiang zisebenza nzima ukukhuthaza ukwakhiwa kwemigodi eluhlaza; iimarike zaphesheya kwezilwandle ezifana neYurophu ne-United States zinemozulu embi yasebusika, amandla okulungelelanisa igridi abuthathaka, kunye namaxabiso aphezulu ombane. Abemi kufuneka balinganise iinkqubo zokugcina amandla ezinobushushu obuphantsi ukuqinisekisa ukusetyenziswa kombane okuzinzileyo ebusika...
Imfuno yemarike yobushushu obuphantsi obusebenza kakuhleiibhetri ze-lithiumingxamisekile kakhulu, kwaye iibhetri zeXingdong Lithium ezinobushushu obuphantsi azikwazi nje ukuhlangabezana ngokupheleleyo neemfuno zeemeko zokusetyenziswa ezikhankanyiweyo apha ngasentla, kodwa zenziwe ngobuninzi kwaye zingasetyenziswa ngokukhawuleza.
Kwinqanaba lokunciphisa iindleko eziluhlaza, kuphela ngokuqhubela phambili ubuchule bobuchwephesha kunye nophuhliso lwemizi-mveliso apho sinokukhawulezisa uphuhliso lwemveliso esemgangathweni omtsha kwaye sifezekise ngcono iinjongo "zekhabhoni ezimbini". Iibhetri zeXingdong Lithium ezinobushushu obuphantsi ziyaphula imiqathango yendawo kwaye zingasetyenziswa kakhulu ekufakeni umbane kwizixhobo zobunjineli obunzima, kunye nokugcinwa kwamandla/amandla kwiindawo ezinobushushu obuphantsi kwihlabathi liphela.
