Ngaba iibhetri ze-lithium iron phosphate ziya kugqabhuka zize zibambe umlilo?

Kule minyaka yangoku,iibhetri ze-lithium-ionzibe yimithombo ebalulekileyo yamandla kwizixhobo ezahlukeneyo zombane. Nangona kunjalo, iinkxalabo zokhuseleko ezijikeleze ezi bhetri zivuse ingxoxo malunga neengozi ezinokuthi zibekho. I-Lithium Iron Phosphate (LiFePO4) yikhemistri ethile yebhetri efumene ingqalelo ngenxa yokhuseleko oluphuculweyo xa kuthelekiswa neebhetri zeLi-ion zendabuko. Ngokuchasene nezinye iingcamango eziphosakeleyo, iibhetri ze-lithium iron phosphate azibeki ugqabhuko-dubulo okanye isoyikiso somlilo. Kule nqaku, sijonge ukucima le ngcaciso engafanelekanga kwaye sicacise iimpawu zokhuseleko lweebhetri ze-LiFePO4.

Funda malunga neebhetri ze-lithium iron phosphate

Ibhetri ye-LiFePO4 yibhetri ye-lithium-ion ephezulu esebenzisa i-lithium iron phosphate njenge-cathode material. Le khemistry ibonelela ngeenzuzo ezibalulekileyo, kubandakanya ukuxinana kwamandla aphezulu, ubomi bomjikelo omde, izinga eliphantsi lokuzikhupha, kwaye okona kubaluleke kakhulu, ukhuseleko olongeziweyo. Ngoyilo, iibhetri ze-lithium iron phosphate zizinzile ngokwendalo kwaye zinomngcipheko osezantsi wokubaleka kwe-thermal-into enokukhokelela kuqhushumbo kunye nomlilo.

Isayensi emva kokhuseleko lwebhetri ye-LiFePO4

Esinye sezizathu eziphambili zokuba iibhetri ze-LiFePO4 zibhekwa njengekhuselekile yinkqubo yazo ezinzileyo ye-crystalline. Ngokungafaniyo nezinye iibhetri ze-lithium-ion ezinezixhobo ze-cathode ezibandakanya i-lithium cobalt oxide okanye i-lithium nickel manganese cobalt (NMC), i-LiFePO4 inesakhelo esizinzile. Esi sakhiwo se-crystalline sivumela ukutshatyalaliswa kobushushu obungcono ngexesha lokusebenza kwebhetri, ukunciphisa umngcipheko wokushisa kunye nokukhutshwa kwe-thermal.

Ukongeza, ikhemistri yebhetri yeLiFePO4 inobushushu obuphezulu bokubola xa kuthelekiswa nezinye iikhemistri zeLi-ion. Oku kuthetha ukuba iibhetri ze-LiFePO4 zinokumelana nokushisa okuphezulu ngaphandle kokuphuka kwe-thermal, ukwandisa umda wokhuseleko kwizicelo ezahlukeneyo.

Amanyathelo okhuseleko kuyilo lwebhetri yeLiFePO4

Amanyathelo okhuseleko ahlukeneyo asetyenziswa kwinkqubo yokwenziwa kweebhetri ze-LiFePO4 ukunciphisa umngcipheko wokuqhuma kunye nomlilo. La manyathelo anceda ukuphucula ukhuseleko jikelele kunye nokuthembeka kweebhetri ze-LiFePO4. Ezinye iimpawu zokhuseleko eziphawulekayo ziquka:

1. I-electrolyte ezinzileyo: Iibhetri ze-LiFePO4 zisebenzisa i-electrolyte engatshanga, ngokungafaniyo neebhetri ze-lithium-ion zendabuko ezisebenzisa i-electrolyte yezinto eziphilayo ezinokutsha. Oku kuphelisa ukutsha kwe-electrolyte, okunciphisa kakhulu umngcipheko womlilo.

2. Inkqubo yokulawula ibhetri (BMS): Ipakethi yebhetri ye-LiFePO4 nganye iqulethe i-BMS, enemisebenzi efana nokukhusela i-overcharge, ukukhuselwa kokukhupha, kunye nokukhusela isiphaluka esifutshane. I-BMS isoloko ibeka iliso kwaye ilawula amandla ombane ebhetri, okwangoku, kunye nobushushu ukuqinisekisa ukuba ibhetri isebenza ngokukhuselekileyo.

3. Uthintelo lwe-Thermal Runaway: Iibhetri ze-LiFePO4 azithandeki kangako ekubalekeni kwe-thermal ngenxa ye-chemistry yazo ekhuselekileyo. Kwimeko yesiganeko esigqithisileyo, umzi-mveliso webhetri ye-lifepo4 uhlala ukongeza iindlela zokukhusela ukushisa, ezifana ne-fuses ye-thermal okanye izindlu ezikwazi ukumelana nobushushu, ukunciphisa umngcipheko.

Ukusetyenziswa kunye neenzuzo zebhetri yeLiFePO4

Iibhetri ze-LiFePO4 zisetyenziswa kumashishini ahlukeneyo, kuquka izithuthi zombane (EVs), ukugcinwa kwamandla ahlaziyekayo, i-electronics yabathengi, kunye nezixhobo zonyango. Ukhuseleko lwabo olomeleziweyo, ubomi obude, kunye nokuthembeka kwabo kubenza balungele usetyenziso olunzima ngolo hlobo.

Ukuququmbela

Ngokuchaseneyo neengcamango eziphosakeleyo, iibhetri zeLiFePO4 azikho mngcipheko wokuqhuma okanye umlilo. Ubume bayo obuzinzile bekristale, ubushushu obuphezulu bokubola kwe-thermal, kunye nemilinganiselo yokhuseleko ebandakanyiweyo kwinkqubo yokuvelisa iyenza ikhuseleke ngokwendalo. Ngokukhula kwemfuno yezisombululo zokugcina amandla aphezulu, iibhetri ze-lithium iron phosphate zibekwe njengokhetho oluthembekileyo nolukhuselekileyo kumashishini ahlukeneyo. Ulwazi olungelulo malunga nokhuseleko lwebhetri kufuneka lujongwe kwaye ulwazi oluchanekileyo lukhuthazwe ukuqinisekisa ukuba abantu benza izigqibo ezizizo malunga nokukhetha amandla.

Ukuba unomdla kwiibhetri ze-lithium iron phosphate, wamkelekile ukuba uqhagamshelane lifepo4 ibhetri yefektri Radiance ukuyaFunda ngokugqithisileyo.
