I-Lithium iron phosphate njengenye yeentlobo zebhetri zangoku zeenqwelo zombane, ezibonakaliswa ngokuzinza kwayo ngokuzinzileyo kwe-thermal, iindleko zemveliso aziphezulu, ubomi benkonzo ende, njl. ye-minus 10 degrees, nangona ibhetri ingasetyenziswa ngokuqhelekileyo, kodwa ukusebenza kakuhle kokutshaja kuya kuncitshiswa kakhulu.
Kuba i-lithium iron phosphate ebusika imbi kakhulu le nkcazo, enyanisweni, ubusika obuphantsi be-lithium ye-iron phosphate iya kuba nkulu kunokonakala kwebhetri ye-lithium, kodwa ayinkulu.Ngaphantsi kweemeko ezifanayo, ukuba isithuthi esixhotywe ngeebhetri ze-lithium ze-ternary siya kuncipha i-25% ngenxa yobushushu obuphantsi bobusika, ngelixa i-lithium iron phosphate inokufikelela kuma-30%.Umsantsa phakathi kwezi zibini unjalo nje, kwaye awukho mkhulu njengoko umsantsa okuthethwa ngawo ngabanye abantu kwi-intanethi.Ukongeza, i-gap ayigqitywanga ngokupheleleyo kwiipropathi zangaphakathi zebhetri.
Umahluko phakathi kwe-lithium iron phosphate kunye ne-ternary lithium uthelekiso lwebhetri
Ubuninzi bamandla ebhetri sisalathiso esichaphazela ukusebenza koluhlu lwezithuthi zamandla amatsha.Uxinano lwamandla ebhetri yelithium yentsimbi yephosphate lumalunga ne-110Wh/kg kuphela, ngelixa uxinano lwamandla ebhetri ye-ternary luyi-200Wh/kg.oko kukuthi, ubunzima obufanayo bebhetri, i-ternary lithium ibhetri ye-energy density yi-1.7 amaxesha ebhetri ye-lithium iron phosphate, ibhetri ye-lithium ye-ternary inokuzisa uluhlu olude lwezithuthi zamandla amatsha.
Ibhetri ye-lithium ye-iron phosphate okwangoku lolona uzinzo lwe-thermal lwebhetri yamandla, ngokokhuseleko xa kuthelekiswa neebhetri ze-ternary lithium zinezibonelelo ezipheleleyo.I-Lithium iron phosphate ibhetri ye-electrothermal incopho ukuya kuma-350 ℃, ubume bekhemikhali yangaphakathi yebhetri ifuna ukufikelela kuma-500 ~ 600 ℃ phambi kokuba iqale ukubola;ngelixa uzinzo lwe-thermal ye-ternary lithium ibhetri yokusebenza ngokubanzi, iya kuqala ukubola malunga ne-300 ℃. Ibhetri ye-lithium ye-iron phosphate okwangoku iyona nto ingcono yokuqina kwe-thermal yebhetri yamandla, ngokokhuseleko xa kuthelekiswa neebhetri ze-lithium ze-ternary zineenzuzo ezipheleleyo. .I-Lithium iron phosphate ibhetri ye-electrothermal incopho ukuya kuma-350 ℃, ubume bekhemikhali yangaphakathi yebhetri ifuna ukufikelela kuma-500 ~ 600 ℃ phambi kokuba iqale ukubola;ngelixa uzinzo lwe-thermal ye-ternary lithium ibhetri yokusebenza ngokubanzi, iya kuqala ukubola malunga ne-300 ℃. Ibhetri ye-lithium ye-iron phosphate okwangoku iyona nto ingcono yokuqina kwe-thermal yebhetri yamandla, ngokokhuseleko xa kuthelekiswa neebhetri ze-lithium ze-ternary zineenzuzo ezipheleleyo. .I-Lithium iron phosphate ibhetri ye-electrothermal incopho ukuya kuma-350 ℃, ubume bekhemikhali yangaphakathi yebhetri ifuna ukufikelela kuma-500 ~ 600 ℃ phambi kokuba iqale ukubola;ngelixa uzinzo lwe-thermal ye-ternary lithium ibhetri yokusebenza ngokubanzi, iya kuqala ukubola malunga ne-300 ℃. Ibhetri ye-lithium ye-iron phosphate okwangoku iyona nto ingcono yokuqina kwe-thermal yebhetri yamandla, ngokokhuseleko xa kuthelekiswa neebhetri ze-lithium ze-ternary zineenzuzo ezipheleleyo. .I-Lithium iron phosphate ibhetri ye-electrothermal incopho ukuya kuma-350 ℃, ubume bekhemikhali yangaphakathi yebhetri ifuna ukufikelela kuma-500 ~ 600 ℃ phambi kokuba iqale ukubola;ngelixa uzinzo lwe-thermal ye-ternary lithium ibhetri yokusebenza ngokubanzi, iya kuqala ukubola malunga ne-300 ℃.
Iibhetri ze-Ternary lithium zisebenza ngakumbi.Idatha yovavanyo ibonisa ukuba umahluko phakathi kwezi zibini awukho kakhulu xa utshaja phantsi kweemeko ze-10 ℃, kodwa ngaphezu kwe-10 ℃ iya kukhupha, kwi-20 ℃ ukutshaja, umlinganiselo oqhubekayo wangoku we-ternary lithium iibhetri yi-52.75%, umlinganiselo oqhubekayo we-lithium. i-iron phosphate yi-10.08%, eyokuqala ngama-5 amaxesha okugqibela.
Ubomi bomjikelo webhetri ye-lithium ye-iron phosphate bungcono kunebhetri ye-lithium ye-ternary, i-ternary lithium ibhetri ubomi bethiyori ngamaxesha angama-2000, kodwa ngokusisiseko ukuya kwi-1000 imijikelo, ukubola komthamo ukuya kuma-60%.Nangona i-shishini lihle kakhulu iTesla, emva kwamaxesha e-3000 inokugcina kuphela i-70% yamandla, ngelixa i-lithium iron phosphate ibhetri emva komjikelezo ofanayo, kodwa kunye ne-80% yomthamo.
Ngokwahlukileyo, ukhuseleko lwebhetri ye-lithium iron phosphate, ubomi obude, ukumelana nobushushu obuphezulu;I-ternary lithium ibhetri yobunzima bokukhanya, ukusebenza kakuhle kokutshaja, ukumelana nobushushu obuphantsi.Ngoko ke, umahluko phakathi kwezi zibini eziveliswe lixesha kunye nendawo yokuguquguquka kwazo ngokufanelekileyo sisizathu sokuhlalisana.
