I-Battery ye-Lithium Phosphate Ingakhetha Kanjani Ubuhleli Kulingana Nezinye I-Chemistry?

Ukuziqonda Izici Ezihlelweyo ZeKhemikhali YeLiFePO4

Uguquko lwe-teknoloji yebhatere ayisendulo ithile kusidzingo esisha emthwakanweni wokugcina amandla. Esikhundleni sokuqala kwale nyanga iphinde iphume ubuthi obuncedisiwe ngamphopho , ngokwahlukile kuthiwa yi-LiFePO4, ekhulekile kakhulu ngendlela yobulungiswa bempilo yalo kunzima ezihlukene zelithiyamhi lithiyamhi. Lolu teknoloji ethembekile wabandakanya indlela esebenzisa ngayo ukugcina kwezimali, ekunika umlando omuhle wezimali, imfundo, nesivinini.

Umbono wesivumelwano sebhatere layithiyamhi elibhekene nobuchopho kumahluko ngemithombo. Umfaniso wocingo olwandle lwephosphate uphinde uphinde uboneke emandleni apholileyo abahleli babhatere elithiyamhi angalifani. Lokhu kubonakala kwangaphandle kokuphila kwebhatere kwenzeke kube lula kulokho okuthi kusetyenziselwa kakhulu ekuqashini izimali zokuphila nezimali zezimali njengoko kuyasebenza kakhulu.

Iziphumo Ezinhle Zobulungiswa BeLithiyamhi Elibhekene NePhosphate

Ubunzima Bokushisa Nokungatholakali Kokuqhuma

Ingcenye encane kakhulu yesimilo yebheti lika-lithium phosphate ibaluleke kakhulu ekuphileni kwempahla yayo. Ngaphandle kwebheti ye-lithium-ion ephatha kobalt njengokothe, umongo wophosphate uphila ngempahla emandleni aphezulu. Lokhu kumenza kube lula ukungabi namathuba okuthi aqede ngokugcwele, into engaba yindlela eqondene yokubulala i-battery futhi iqaphe amathambo emehluko engaphelelwa.

Iziphazama zophosphate kule bheti zinkona kakhulu kunazo ezizayo zika-cobalt-oxide kwi-lithium-ion. Nangoba isimo siphikisana kakhulu, njengoko kusabalala okunembuzi noma okunemvelo, i-batteries zakhiwa ngaphosphate zilindile impahla yazo. Lokhu kubaluleka kakhulu kumenza kube lula ukungabi namathuba okuthi aqede noma aphethe, kanti kuyinto eqondile kakhulu ekusebenziswa kuyo lapho isimilo iyisidingo esibalulekile.

Ukuphelelwa Kwegesi Nokuphelelwa Kwesakhiwo

Umboniso wokugcina kwebhatereyithi yelithiyamhi fosfethreyithi uphinde uboneke indlela eyodwa yokuphepha. Isakhiwo sase kristali yesiliva senqolobane sokucaphuka kwenza uhlelo olukhulu okungavimisele ukuthutha kwe-oksijini noma ngemiphumela engcono. Lokhu kuyahlukana ngempela nezinye izinhlelo zelithiyamhi, lapho ukuthutha kwe-oksijini kungakhula ukuzulazula kwesibindi futhi kube yisizathu sobubi obungcono.

Ngaphezu kwalokho, inhlelo yokugcina ebase ku-fosfethreyithi ibalulekile ngokushesha ngemuva kwezikhathi zokulayisha nokusebenzisa. Lokhu kubaluleka kusho ukuthi ibhatereyi iphila isimo sakhe nangenhlalo emlandweni, kunciphisa umngeni wokudluliswa phantsi kwegumbi futhi izinye iziphumo ezinezimilo ezingcono ezingahleliwa ngokuvuthi kuzinhlelo ezingaphansi kwezimali.

Iziphumo Zokusebenza Ngaphandle Kokulahlekelwa Kokuqinisekiswa

Ukudala Kweminyaka Okusebenza Nomndeni

Ukukhona kwe-battery ye lithium phosphate kubonisa ubudala obunzima ngaphandle kokulahla izici zakho zokuphepha. Lezi zibhatteri zihlenga kakhulu ama-2000-7000 amacala ngelikala lomsebenzi ophephile, ihlukana kakhulu nezibhatteri ezihlelekile ze-lithium-ion ezenza ukulahlwa okuningi emva kwezingu-500-1500.

Lo budala obude befuziswe ngokushintshayo kumthwalo ongenhla we-phosphate cathode, okungavumi ukwakha kwezinhlenywa kanye nezinye izindlela zokulahlwa ezingathintela umsebenzi nokuphepha kwizibhatteri ezinye. Okuthola yile bhatteri ayisona kuphela esebenzisa khona kodwa ibe nemithwalo yokuphepha yonke indawo yesikhathi sakusebenza.

Ukusebenza okuphathelene ngesimiso

Xa kuzotshiselwa emzimbeni engcono, amabhethereyhi akha lithiyam phasphethi ayagcina iqiniso labasebenzi ngaphandle kokulahleka kwesivumelwano. Azakwazi ukunika umsebenzi omulinganayo noma kumzimba ophezulu, futhi izidingo zabo zeqembu lethirmali zingahlakaniki ngokushesha kangange ezinye izinhlelo zelithiyam-ayoni.

Lokhu kugcinwa kumzimba kuphela kumaqondo amaningi, lapho amabhethereyhi akha lithiyam phasphethi asebenza ngendlela esivikelwayo nokulinganayo. Ukukhathazeka kwezinhlelo yethirmali kungakhathazeki okwenzeka ngokuphelele kusivumelwano sokuthi noma ngalaba mzimba omkhulu noma kumzimba wokulayisha ngokushesha, ibhethereyi iyagcina isivumelwano sabo.

Izidingo Zokuphepha Kwemvelo Nokuphepha Kwezimali

Ukuphakamiswa Kwesikhathu Sesiqhathu

Izint advantages zokuphepha kwebheti yelithiyamu yesifazane ziyaphandle kwezinkinga zokusebenza ngokushesha kusukela ekuphileni kwemvelo. I-chemistry esisodwa ngesifazane sikhululekile kumvelo, asinamathambo amnandi noma izinto ezilahlekile. Lokhu kuyakha le bheti ibe yinkululeko ayengaphansi kwalokho kodwa futhi ekwakheni nokususa ngemuva kokusetshenziswa.

Umsebenzi wokwakha i-bheti yelithiyamu yesifazane uyakha iqembu elincane le-carbon kunalo naliphi na teknoloji ye-lithiyamu-ion. Leli phawu lokuphephile kumvelo libaluleke kakhulu njengoba umhlaba uphindelela emthethweni wokuphila okuhle kufuneka kube khona umthelela woko konke okubangelwa ngalo.

Iziphawu zokuphepha ezineyimali ebalulekile

Nakuba ubuhle lokusebenza kuyindima ephakeme, izinkinga zomnotho zokwenziwa kwamabhethiri azikwenzeki. Amabhethiri we-lithium phosphate azenza izici zabo ezihle kakhulu ngaphandle kokuthinta imali enkulu enguqukayo ekuphileni kwizinhlelo zamabhethiri amasha. Izinto ezisuselwe kuzo njengezimali ezenziwa kuzo ziphuhlile futhi zinzima ngaphansi kukaqo kudingayo kuzo izimboni ezivela ku-cobalt.

Ukuncipha kokudinga kwezinhlelo eziningi zokuphatha ubuhle, ngokudide ngezinsuku zokusebenza ezinde, kwenza amabhethiri we-lithium phosphate abe yindlela efanelekileyo ngokomnotho uma kucaciswa umnotho wokubona konke. Lolu phawu olungcono awufani nokulahleka kwebuhle - kodwa futhi izici zobuhle okwakhe kuyinto ethinta ukuthi lezi zimboni zibe nzima ngokudala.

Imibuzo Evame Ukubuzwa

Yini eyakhiwa ngayo amabhethiri we-lithium phosphate abe nobuhle ngempela kunazo zonke izimboni ze-lithium-ion?

Ikhemikhali yesicathululo esise phosphate siphindelekeke kakhulu nokuphila kwesibonelo, sivikela ukuthi kungahlengelwe kakhulu futhi kugcine ubunzima bokudala noma kube sekupheleni kwezimo. Iziphazimulo ezizimeleyo zezincwadi nekristalu ye-olivine zisungula i-khemikhali yebhatere enobuhlobo obubanzi engavukeli futhi ayinakunquma okusha.

Kuyini into ebhatere yesilithiyam le-phosphate iyakudinga ukuze isebenze ngokushesha ngaphandle kokuphazanyiswa?

Ibhatere yesilithiyam le-phosphate ihlala iyasebenza phakathi kwezinguquko ezingu-2000-7000 ngaphansi kwegunya lakhe nangaphezu kwemfundo yayo. Lokhu kude kakhulu kunabantu ababiliyoni besilithiyam se-lithium, futhi izici zokuphepha zihlala ziqhubekisa kuqala kuya ekugcineni komsebenzi wabhatere.

Ibhatere yesilithiyam le-phosphate iphepha kangakanani ekugcineni amandla endlini?

Yebo, i-batteries ze-lithium phosphate zihambelana kahle kugcinwa kwamandla endlini ngokuphelele kwezimali zabo, ubunzima bokugcina, nokukhathazeka kwe-thermal runaway. Ubude bomlando nokunciphisa ukulungiswa okudingayo kuzo kuthinta yona indlela ehlukile ekugcinweni kwendlu apho isetyenziso kuyindawo ebalulekileyo.
