Yintoni umahluko phakathi kwebhetri yeblade kunye ne-NMC lithium ibhetri? Yeyiphi kubo engcono, kwaye ngawaphi amaxesha afaneleke ngakumbi? Ibhetri yeBlade luhlobo lwebhetri ye-lithium iron phosphate (LiFePO4), kunye ne-ternary lithium ibhetri ibizwa ngokupheleleyo ngokuba yi-ternary material battery. Ngokuqhelekileyo, ibhekisela ekusebenziseni i-nickel cobalt lithium manganese oxide (Li (NiCoMn) O2, NCM) okanye i-nickel cobalt aluminium (NCA) ibhetri ye-ternary cathode impahla, kunye nomlinganiselo wetyuwa ye-nickel, ityuwa ye-cobalt kunye netyuwa ye-manganese ihlengahlengiswa njengezintathu. amacandelo ahlukeneyo.

I-1, ibhetri ye-Blade (i-lithium iron phosphate) 1635492640186392.jpg Ibhetri ye-lithium yentsimbi ye-phosphate isebenzisa i-lithium iron phosphate (LiFePO4) njengesixhobo se-cathode kunye nentsimbi njengento ekrwada yebhetri etshajwayo, enexabiso eliphantsi, akukho zintsimbi ezinzima kunye nongcoliseko oluncinci lokusingqongileyo. Uthini umahluko phakathi kwebhetri yeblade kunye ne-ternary lithium ion ibhetri kwi-lithium iron phosphate crystal? “Ibhetri yeBlade” yeye-lithium iron phosphate ion ibhetri. I-Lithium iron phosphate ion ibhetri ithatha i-lithium iron phosphate (LiFePO4) njengesixhobo se-cathode kunye nentsimbi njengento ekrwada yebhetri etshajwayo. Ineenzuzo zexabiso eliphantsi, akukho zinyithi ezinzima kunye nongcoliseko oluncinci lokusingqongileyo. Ibhondi ye-PO kwi-lithium iron phosphate crystal yibhondi eyomeleleyo, engayi kuvuza xa igcinwe kwi-voltage engu-zero. Imiba yokhuseleko efana nobushushu obuphezulu okanye ixesha lokutshaja, ukutshaja ngokukhawuleza, ukukhupha amandla aphezulu, akukho nkumbulo, ubomi bomjikelo ophezulu, iimpawu ezisezantsi zobushushu obuphantsi kakhulu, uxinano lokungcangcazela okuphantsi, amandla aphantsi, isivuno semveliso kunye nokungaguquguquki kuye kwabuzwa.

2, ibhetri ye-ternary lithium ion Ibhetri ye-lithium-ion ibizwa ngokupheleleyo ngokuba yi-ternary material ibhetri, ebhekisela ngokubanzi kusetyenziso lwe-nickel cobalt lithium manganese oxide (Li (NiCoMn) O2, NCM) okanye i-nickel cobalt aluminium (NCA) ibhetri ye-ternary cathode materials. , kunye nomlinganiselo wetyuwa ye-nickel, ityuwa ye-cobalt kunye netyuwa ye-manganese ihlengahlengiswa njengamacandelo amathathu ahlukeneyo. Ibhetri ebizwa ngokuba yi-ternary ibandakanya iintlobo ezininzi zeebhetri ezinokutshajwa kwakhona. Ukusuka kwinkangeleko, inokwahlulwa ibe yibhetri yokupakisha eguquguqukayo, ibhetri yecylindrical etshajwayo kunye nebhetri ephindwe kabini yeqokobhe. Amandla ayo aqhelekileyo angaphezulu kwawamandla, iqonga lenkonzo yamandla ombane aphezulu asebenzayo, ingxinano yokungcangcazela okuphezulu, iimayile, amandla aphezulu kunye nokuthembeka kobushushu obuphezulu, kodwa ineempawu ezibalaseleyo zobushushu obuphantsi kakhulu kunye neendleko eziphezulu zeprojekthi. Iingenelo kunye nokungalunganga kwebhetri ye-lithium ion engasentla kunye ne-lithium iron phosphate amandla ibhetri ye-lithium inokugqanyiswa. Iinzuzo eziphambili zebhetri ye-lithium ion phosphate kukhuseleko kunye nokuzinza kunye nobomi obude benkonzo yenkqubo yokujikeleza. Izinto ezingeloncedo ziimpawu zobushushu obuphantsi kakhulu kunye namandla aphantsi ngokwentelekiso. Nangona kunjalo, ibhetri ye-lithium-ion inokuqinisekisa ukusebenza kakuhle koxinzelelo olunxulumeneyo, kodwa iimpawu zayo zobushushu obuphezulu zihlwempuzekile. Xa kuthelekiswa nebhetri ye-lithium-ion phosphoric acid, ukhuseleko lwayo kunye nokuthembeka kwayo kuncinci. Ngokunyuka koshishino lwezithuthi zamandla amatsha, ukusetyenziswa kwebhetri etshajwayo kuya kuxhaphaka ngakumbi. Ayinguye wonke umntu oqhelene neebhetri ze-lithium-ion ezisetyenziswa kwiimoto. Ngaphandle kokucwangciswa kwezithuthi zombane ezicocekileyo, kwakhona ngumzekelo obalaseleyo kwezinye iindawo, ezifana neefowuni eziphathwayo. Yonke into ilungile kwaye imbi. Ngaphezulu kwenqanaba lesicelo esilungileyo, kufuneka sikuqonde ngokupheleleyo. Inzuzo yeebhetri ze-lithium-ion kukuba ayinayo imemori kunye noluhlu olubanzi lobushushu bokusebenza. Kwanasemva kwexesha elide lokusebenza, ukuthembeka kwento kunokugcinwa. Iibhetri ze-Lithium ion zahlulwe zibe ziibhetri ze-lithium ion kunye neebhetri zesekondari ze-lithium ion.

3, iinzuzo zokuthelekisa kunye nokungalunganga kwebhetri ye-blade kunye ne-ternary lithium ibhetri Le ibhetri ye-lithium-ion iguquguquka ngakumbi kunebhetri yendabuko ehlaziywayo, ilungele ukutshaja ngokukhawuleza, inokugcina ngaphezu kwe-80% yebhetri ngexesha elifutshane, kwaye ine-polarity enamandla. ukutshixa isakhono. Inamandla amakhulu kunye nobomi obude bebhetri ngaphandle komonakalo kwiikhemikhali. Iziphene ze-ternary lithium ion ibhetri ziyabonakala. Okwangoku, iibhetri ezininzi ze-lithium-ion zisebenza kwiinkqubo zamanzi okanye ze-colloidal. Ubume bebhetri ye-lithium-ion ye-ternary ifana nale. Ebusika, ngenxa yobushushu obuphantsi emazantsi, ulwelo okanye ijeli kwibhetri etshajwayo iya kucotha kwaye icothe nokuba ayidibani. Isiphumo esibi kukuba inkqubo yokusebenza yebhetri etshajwayo iya kuncitshiswa, nto leyo eya kubangela ukunqongophala kwamandla, ukunqongophala kwamandla kunye nokuvalwa. Ibhetri etshajwayo entloko ibizwa ngokuba yi-lithium iron phosphate rechargeable battery. Idla ngokubizwa ngokuba yibhetri egcwalisekayo ngenxa yokuba ifakwe kwipakethi yebhetri njengeblade. Ibhetri yesibini yemela inamandla okumelana nokubanda kunebhetri ye-lithium-ion. I-lithium ion core inendawo enkulu yokukhupha i-thermal kunye namandla athile aphezulu. Ubuninzi bebhetri ye-blade ayikho phezulu kune-ternary lithium-ion ibhetri, kodwa into yokhuseleko iphezulu kunaleyo ye-ternary lithium-ion ibhetri. Xa kuthelekiswa nokungazinzi kwe-ternary lithium-ion ibhetri, i-knife disk ibhetri yesibini inomsebenzi ocebileyo wokhuseleko kunye nobomi benkonzo ende. Emva kokufunda eli nqaku, sifumene ukuba enyanisweni, iibhetri ze-blade kunye neebhetri ze-ternary lithium zineenzuzo zazo. Ukongeza kwintsebenzo yabo, amaxabiso abo ahluke kakhulu. Ukuba ufuna ukwazi ngakumbi malunga nomahluko phakathi kweebhetri ze-blade kunye neebhetri ze-lithium ze-ternary kwaye zikuncede wenze ukhetho, qhagamshelana nathi lukhetho olungcono.
