Intshayelelo:
Iibhetri ze-ternary lithium kunyeiibhetri ze-lithium iron phosphatezimbini iintlobo eziphambili zeebhetri ze-lithium okwangoku ezisetyenziswa ngokubanzi kwizithuthi zombane, iinkqubo zokugcina amandla kunye nezinye izixhobo zombane. Kodwa ngaba uye waziqonda iimpawu zabo nokwahluka kwazo? Ukubunjwa kweekhemikhali zabo, iimpawu zokusebenza kunye neendawo zokusetyenziswa zihluke kakhulu. Masifunde ngakumbi ngabo nge-Heltec.
Ukwakhiwa kwezinto:
Ibhetri ye-lithium ye-ternary: Isixhobo se-electrode esilungileyo sidla ngokuba yi-nickel cobalt manganese oxide (NCM) okanye i-nickel cobalt aluminium oxide (NCA), eyenziwe nge-nickel, i-cobalt, i-manganese okanye i-nickel, i-cobalt, i-aluminiyam kunye nezinye izinto zetsimbi oxides, kunye ne-negative. I-electrode ngokuqhelekileyo yigraphite. Phakathi kwabo, umlinganiselo we-nickel, i-cobalt, i-manganese (okanye i-aluminium) inokulungelelaniswa ngokweemfuno zangempela.
Ibhetri ye-lithium ye-iron phosphate: i-lithium iron phosphate (LiFePO₄) isetyenziswa njengento efanelekileyo ye-electrode, kwaye i-graphite nayo isetyenziselwa i-electrode engalunganga. Ukwakhiwa kweekhemikhali zayo kuzinzile, kwaye ayinayo isinyithi esinzima kunye neentsimbi ezinqabileyo, ezihambelana nokusingqongileyo.
Ukuhlawulisa kunye nokukhupha ukusebenza:
Ibhetri ye-lithium ye-Ternary: intlawulo ekhawulezayo kunye nesantya sokukhutshwa, inokulungelelanisa kwintlawulo ephezulu yangoku kunye nokukhutshwa, ezifanelekileyo kwizixhobo kunye neemeko ezineemfuno eziphezulu zokutshaja isantya, njengezithuthi zombane ezixhasa ukutshaja ngokukhawuleza. Kwimeko yobushushu obuphantsi, ukuhlawuliswa kwayo kunye nokusebenza kokukhutshwa kukwalungile, kwaye ukulahleka kwamandla kuncinci.
Lithium iron phosphate ibhetri: Intlawulo ecothayo kunye nesantya sokukhupha, kodwa intlawulo yomjikelo ozinzileyo kunye nokusebenza kokukhupha. Iyakwazi ukuxhasa izinga eliphezulu lokutshaja kwaye inokuhlawuliswa ngokupheleleyo kwiyure ye-1 ngokukhawuleza, kodwa intlawulo kunye nokusebenza kakuhle kokukhupha ngokuqhelekileyo kujikeleze i-80%, ephantsi kancinane kune-ternary lithium ibhetri. Ngaphantsi kweemeko zokushisa eziphantsi, ukusebenza kwayo kuncipha kakhulu, kwaye izinga lokugcinwa kwebhetri linokuba yi-50% -60 kuphela.
Ukuxinana kwamandla:
Ibhetri ye-lithium ye-Ternary: Ubuninzi bamandla buphezulu kakhulu, budla ngokufikelela ngaphezu kwe-200Wh/kg, kwaye ezinye iimveliso eziphucukileyo zinokudlula i-260Wh/kg. Oku kuvumela iibhetri ze-lithium ze-ternary ukuba zigcine amandla amaninzi kumthamo ofanayo okanye ubunzima, ukunika uluhlu olude lokuqhuba izixhobo, ezifana neenqwelo zombane, ezinokuxhasa izithuthi ukuba zihambe imigama emide.
Ibhetri yeLithium iron phosphate: Uxinzelelo lwamandla lusezantsi noko, lujikeleze i-110-150Wh/kg. Ke ngoko, ukuze ufezekise uluhlu olufanayo lokuqhuba njengeebhetri ze-lithium ze-lithium, iibhetri ze-lithium iron phosphate zinokufuna umthamo omkhulu okanye ubunzima.
Ubomi bomjikelo:
I-Ternary lithium ibhetri: Ubomi bomjikelezo bufutshane, kunye nenani lomjikelezo wethiyori malunga namaxesha angama-2,000. Ekusetyenzisweni okwenyani, umthamo unokuba ubolile ukuya malunga ne-60% emva kwemijikelo ye-1,000. Ukusetyenziswa okungafanelekanga, njengokugqithiswa okanye ukukhupha, kunye nokusetyenziswa kwiindawo eziphezulu zokushisa, kuya kukhawulezisa ukubola kwebhetri.
Ibhetri ye-Lithium ye-iron phosphate: Ubomi bomjikelo omde, kunye nemijikelo engaphezulu kwe-3,500 yentlawulo kunye nokukhupha, kwaye ezinye iibhetri ezikumgangatho ophezulu zinokufikelela nangaphezulu kwamaxesha angama-5,000, elilingana neminyaka engaphezu kwe-10 yokusetyenziswa. Inozinzo oluhle lwe-lattice, kwaye ukufakwa kunye nokususwa kwee-ion ze-lithium kunempembelelo encinci kwi-lattice, kwaye inokubuyisela umva okulungileyo.
Ukhuseleko:
Ibhetri ye-lithium ye-Ternary: ukuzinza okuphantsi kwe-thermal, kulula ukubangela ukubaleka kwe-thermal phantsi kobushushu obuphezulu, i-overcharge, i-short circuit kunye nezinye iimeko, ezikhokelela kumngcipheko ophezulu wokutsha okanye ukuqhuma. Nangona kunjalo, ngokuhambela phambili kweteknoloji kunye nokomelezwa kwamanyathelo okhuseleko, afana nokusetyenziswa kweenkqubo zokulawula ibhetri engaphezulu kunye nokulungiswa kwesakhiwo sebhetri, ukhuseleko lwayo luphucula rhoqo.
Ibhetri ye-lithium ye-phosphate ye-iron: ukuzinza okuhle kwe-thermal, i-electrode efanelekileyo ayikho lula ukukhulula i-oksijini kwiqondo lokushisa eliphezulu, kwaye ayiyi kuqalisa ukubola kude kube yi-700-800 ℃, kwaye ayiyi kukhulula iimolekyuli ze-oksijini xa zijongene nempembelelo, i-puncture, isiphaluka esifutshane kunye ezinye iimeko, kwaye aziqhelani nokutsha okunobundlobongela, kunye nokusebenza okuphezulu kokhuseleko.
Ixabiso:
Ibhetri ye-lithium ye-ternary: kuba i-electrode efanelekileyo iqulethe izinto zetsimbi ezibiza njenge-nickel kunye ne-cobalt, kwaye iimfuno zenkqubo yokuvelisa ziphezulu, kwaye iimfuno zokusingqongileyo nazo zingqongqo, ngoko ixabiso liphezulu kakhulu.
Lithium iron phosphate ibhetri: ixabiso lezinto eziluhlaza liphantsi, inkqubo yokuvelisa ilula, kwaye ixabiso lilonke lineenzuzo ezithile. Umzekelo, kwiimoto zamandla amatsha, iimodeli ezineebhetri ze-lithium iron phosphate zihlala ziphantsi ngokwexabiso.
