Kule minyaka yangoku,Ibhetri ye-lithium-ionUbe yimithombo yamandla ebalulekileyo kwizixhobo ezahlukeneyo ze-elektroniki. Nangona kunjalo, iinkxalabo zokhuseleko ezijikeleze ezi bheries ziyingxoxo yemingcipheko yazo enokubakho. I-Lithium i-phosphate i-phosphate (i-worpo4) yi-chemistry yebhetri ethile efumene ingqwalaselo ngenxa yokhuseleko oluphuculweyo xa kuthelekiswa neebhetri ze-li-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-i-iI ye-li-ion. Ngokuchasene nezinye izinto eziphosakeleyo, i-Lithium ye-Inyibium ye-inyibilium phosphatele ayizibeki ukuqhushumba okanye isoyikiso somlilo. Kweli nqaku, sijolise ekuxhaseni le ntetho iphosakeleyo kwaye sicacisa iimpawu zokhuseleko ze-WillPo4.
Funda ngeebhetri ze-phosphate phosphate
Ibhetri ye-Lifepo4 yibhetri ye-Lithium ye-lithium esebenzisa i-lithium ye-lithium i-phosphate njengezixhobo ze-Otomede. Le chemistry inika izibonelelo ezibalulekileyo, kubandakanya ukuxinana kwamandla amakhulu, ubomi obude bobomi, ireyithingi ephantsi yokuzibhokoxa, kwaye kakhulu, kuphuculwe ukhuseleko. NguYilo, i-Lithium yentsimbi phosphatele izinzile ngakumbi kwaye inomngcipheko ophantsi we-thermal rubaway-i-themomenon enokukhokelela kwiiqhushumbisi kunye nemililo.
Inzululwazi yeSayensi yoKhuseleko lwebhetri
Esona sizathu siphambili iibhetri ze-willpo4 ezithathwa njengezikhuselekileyo kukhuseleko lwazo lwe-crystallines. Ngokungafaniyo nezinye iibhetri zeLithium-i-ion ye-Othtoe yeZinto ze-LOTEIM ye-LITIM CoALCE OKANYE i-Lithium Manganese Cobanese (NMC), i-Whildpo4 inesakhelo esizinzileyo. Esi sakhiwo se-crystalline sivumela ukubekwa kwe-share engcono ngexesha lokusebenza kwebhetri, ukunciphisa umngcipheko wokugqitha kakhulu kwaye kuvumelekile ukubaleka okuthe tyaba.
Ukongeza, i-chemistry yetekisi ye-Widpo4 inee-factocation ephezulu ye-thermal ye-thermal ethengiswayo xa kuthelekiswa nezinye i-lion chemisties. Oku kuthetha ukuba iibhetri ze-willpo4 zingamelana namaqondo obushushu aphezulu ngaphandle kokuqhekezwa kwe-thermal, ukwandisa umda wokhuseleko kwizicelo ezahlukeneyo.
Amanyathelo okhuseleko kwi-Lifepo4 uyilo
Amanyathelo okhuseleko ahlukeneyo asetyenziswa kwinkqubo yokwenziwa kweebhetri ze-whindedo4 ukunciphisa umngcipheko wokuqhuma nomlilo. La manyathelo anceda ekuphuculeni ukhuseleko ngokubanzi kunye nokuthembeka kweebhetri zobomi be-worpo4. Ezinye zeempawu zokhuseleko zibandakanya:
I-1. Iibhetri ezizinzileyo: Iibhetri ze-willpo4 zisebenzisa i-electrolytes ezinokutsha, ngokungafaniyo ne-Ion ye-Ion-ion-ion-ion asebenzisa i-electrolyte ye-elektroniki. Oku kuphelisa ukubakho kwe-elektrolyte evuthayo, enciphisa kakhulu umngcipheko womlilo.
I-2. Inkqubo yoLawulo lwebhetri (ii-BMS): Ipakethi nganye yebhetri iqulethe i-BMS, eyenza imisebenzi enjengokhuselo olugqithisileyo, ukhuseleko olugqithisileyo, kunye nokhuseleko lwesekelo olufutshane. I-BMS ngokuqhubekayo ibeka iliso kwaye ilawula i-voltage yebhetri, yangoku, kunye neqondo lokushisa ukuqinisekisa ukusebenza okhuselekileyo nefanelekileyo yebhetri.
3. Uthintelo oluBalekayo: Iibhetri ze-willpo4 ze-worpo4 zithambekele kwi-theminal ye-thermal ngenxa ye-chemistry yabo ekhuselekileyo. Kwimeko yomnyhadala ogqithisileyo, umzi-mveliso webhetri wobomi uhlala usongeza iindlela zoKhuseleko lwe-Irmal, ezinje nge-fuse ye-thermal okanye izindlu ezinganyangeki, ukuqhubela phambili umngcipheko.
Izicelo kunye nezibonelelo zebhetri ye-whildpo4
Iibhetri ze-Wicpo4 zisetyenziswa kwimizi-mveliso eyahlukeneyo, kubandakanya nezithuthi zombane (i-EVs), ukugcina amandla okuhlaziya, i-elektroniki, kunye nezixhobo zonyango. Ukhuseleko lwabo lukhuseleko, ububele, kunye nokuthembeka kwenza ukuba zilungele ezo zicelo zifunwayo.
Ukuququmbela
Ngokuchasene nembono ephosakeleyo, iibhetri ze-willpo4 ingengomngcipheko wokuqhushumba okanye umlilo. Ulwakhiwo lwayo lokukristali, ubushushu obuphakathi obuphezulu, kunye namanyathelo okhuseleko abandakanyiwe kwinkqubo yokuvelisa kwenza ukuba ikhuseleke ngokwendalo. Ngemfuno ekhulayo yezisombululo zokugcina izinto eziphezulu, i-Lithium ye-lithium yentsimbi phosphatele ibekwe njengonyulo oluthembekileyo nolwenziweyo kumashishini ahlukeneyo. Ukufakwa gwenxa malunga nokhuseleko lwebhetri kufuneka kujongwane kwaye ulwazi oluchanekileyo lukhuthaze ukuqinisekisa ukuba abantu benze izigqibo ezinolwazi malunga nokhetho lwamandla.
Ukuba unomdla kwiibhetri ze-lithium ze-phosphatele, wamkelekile ukuba uqhagamshelane ne-radias ye-phrias yetekisiFunda ngokugqithisileyo.
