Iyini i-Lithium Iron Phosphate?

Kungumbono oyiphutha ojwayelekile ukuthi amabhethri e-lithium iron phosphate ahlukile kunamabhethri e-lithium-ion.Eqinisweni, kunezinhlobo eziningi zamabhethri e-lithium-ion, futhi i-lithium iron phosphate ingenye yazo.

Ake sibheke ukuthi iyini ngempela i-lithium iron phosphate, kungani iyisinqumo esihle sezinhlobo ezithile zamabhethri, nokuthi iqhathaniswa kanjani nezinye izinketho zebhethri ye-lithium-ion.

Iyini i-Lithium Iron Phosphate?

I-Lithium iron phosphate iyinhlanganisela yamakhemikhali i-LiFePO4 noma i-“LFP” ngamafuphi.I-LFP inikeza ukusebenza okuhle kwe-electrochemical, ukumelana okuphansi futhi ingenye yezinto eziphephile nezizinzile kakhulu ze-cathode ezitholakalayo kumabhethri e-lithium-ion.

Liyini Ibhethri ye-Lithium Iron Phosphate?

Amabhethri e-lithium iron phosphate awuhlobo lwebhethri ye-lithium-ion esebenzisa i-lithium iron phosphate njenge-cathode material ukugcina i-lithium ion.Amabhethri e-LFP ngokuvamile asebenzisa i-graphite njengento ye-anode.Ukwakheka kwamakhemikhali kwamabhethri e-LFP kuwanika isilinganiso esiphezulu samanje, ukuzinza okuhle kwe-thermal, kanye nomjikelezo wempilo omude.

Amabhethri amaningi e-lithium iron phosphate anamaseli amabhethri amane anentambo ochungechungeni.I-voltage yegama yeseli yebhethri ye-LFP ingu-3.2 volts.Ukuxhuma amaseli ebhethri e-LFP amane ochungechungeni kubangela ibhethri elingu-12-volt okuyindlela enhle yokushintshanisa yamabhethri amaningi angu-12-volt lead-acid.

I-Lithium Iron Phosphate Vs.Ezinye Izinhlobo ze-Lithium-Ion

I-lithium iron phosphate ingenye yezinhlobo eziningi zamabhethri e-lithium-ion.Ukushintsha ikhemikhali ye-cathode kudala izinhlobo ezahlukene zamabhethri e-lithium-ion.Ezinye zezinketho ezivame kakhulu i-Lithium Cobalt Oxide (LCO), i-Lithium Manganese Oxide (LMO), i-Lithium Nickel Cobalt Aluminium Oxide (NCA), i-Lithium Nickel Manganese Cobalt Oxide (NMC), ne-Lithium Titanate (LTO).

Ngalunye lwalezi zinhlobo zebhethri zinamandla ahlukahlukene kanye nobuthakathaka okubenza bafaneleke ezinhlelweni zokusebenza ezahlukene.Uma sibheka izici eziyinhloko zalezi zinhlobo zamabhethri, singabona ukuthi amabhethri e-lithium iron phosphate ame kuphi nokuthi yiziphi izinhlelo zokusebenza ezingcono kakhulu kuzo.

Ukuminyana kwamandla

Amabhethri e-LFP anesinye sezilinganiso zamandla eziqondile kakhulu phakathi kwezinye izinhlobo ze-lithium-ion.Ngamanye amazwi, amandla athile aphezulu asho ukuthi amabhethri e-LFP angaletha amanani aphezulu wamanje namandla ngaphandle kokushisa ngokweqile.

Ngakolunye uhlangothi, kubalulekile ukukhumbula ukuthi amabhethri e-LFP anesinye sezilinganiso zamandla ezithize eziphansi kakhulu.Amandla athize aphansi asho ukuthi amabhethri e-LFP anomthamo omncane wokugcina amandla ngesisindo kunezinye izinketho ze-lithium-ion.Lokhu ngokuvamile akuyona into enkulu ngoba ukukhulisa amandla ebhange lebhethri kungenziwa ngokuxhuma amabhethri amaningi ngokuhambisana.Lokhu kungase kungafaneleki ohlelweni lapho kudingeka khona ukuminyana kwamandla ngokwedlulele endaweni elula kakhulu, njengezimoto ezisebenza ngogesi zebhethri.

Imijikelezo Yempilo Yebhethri

Amabhethri e-lithium iron phosphate anesikhathi sokuphila esiqala cishe emijikelezweni yokukhipha egcwele engu-2,000 futhi anda kuye ngokujula kokukhipha.Amaseli kanye nesistimu yokuphatha ibhethri yangaphakathi (i-BMS) esetshenziswa e-Dragonfly Energy ihlolelwe imijikelezo yokukhipha egcwele engaphezu kuka-5,000 kuyilapho igcina u-80% womthamo webhethri langempela.

I-LFP ingeyesibili kuphela ku-lithium titanate esikhathini sokuphila.Kodwa-ke, amabhethri e-LTO ngokwesiko abe yinketho yebhethri ye-lithium-ion ebiza kakhulu, okuwenza angabizi kakhulu ezinhlelweni eziningi.

Isilinganiso Sokukhipha

Izinga lokukhipha likalwa ngomthamo omningi webhethri, okusho ukuthi izinga lokukhipha elingu-1C lebhethri elingu-100Ah liqhubekayo ngo-100A.Amabhethri e-LFP atholakalela ukuthengisa ngokuvamile anesilinganiso sokukhipha esiqhubekayo esingu-1C kodwa angadlula lesi sikhathi esifushane kuye ngohlelo lokuphatha ibhethri.

Amaseli e-LFP ngokwawo ngokuvamile angahlinzeka ngokukhishwa okungu-25C isikhathi esifushane ngokuphephile.Ikhono lokudlula u-1C likuvumela ukuthi usebenzise amabhethri e-LFP ezinhlelweni zamandla aphezulu okungenzeka zibe nama-spikes okuqalisa ekudwebeni kwamanje.

Amazinga Okushisa Okusebenza

Amabhethri e-LFP awangeni ezimeni ezishisayo kuze kube ngu-270 degrees Celsius.Uma kuqhathaniswa nezinye izinketho zebhethri ze-lithium-ion ezivamile, amabhethri e-LFP anomkhawulo wesibili ophezulu wokushisa wokusebenza.

Ukweqa umkhawulo wezinga lokushisa ebhethri ye-lithium-ion kubangela umonakalo futhi kungaholelaukubaleka okushisayo, okungenzeka kubangele umlilo.Umkhawulo ophezulu wokusebenza we-LFP unciphisa ngokuphawulekayo ithuba lomcimbi wokubaleka okushisayo.Ihlanganiswe ne-BMS yekhwalithi ephezulu yokuvala amaseli kahle ngaphambi kwalezi zimo (cishe ama-degree Celsius angama-57), i-LFP inikeza izinzuzo ezibalulekile zokuphepha.

Izinzuzo Zokuphepha

Amabhethri e-LFP angomunye wamakhemikhali azinzile azo zonke izinketho ze-lithium-ion.Lokhu kuzinza kuzenza zibe enye yezinketho eziphephe kakhulu kukho kokubili izinhlelo zokusebenza ezibhekene nabathengi nezimboni.

Okuwukuphela kwenketho ephephile ngokuqhathaniswa i-lithium titanate, ephinda ivimbe izindleko futhi engasebenzi kuvoltheji efanele ezimweni eziningi uma kushintshwa i-12V.

I-Lithium Iron Phosphate Vs.Amabhethri e-lead-Acid

Amabhethri e-lithium iron phosphate anikeza amaningiizinzuzo ngaphezu kwamabhethri e-lead-asidi endabuko.Okuphawuleka kakhulu ukuthi amabhethri e-LFP anamandla aphindwe kane ukuminyana kwamabhethri e-lead-acid.Ungakwazi ukujula-umjikelezo wamabhethri e-LFP ngokuphindaphindiwe ngaphandle kokuwalimaza.Aphinde ashaje amabhethri angu-5 ngokushesha kunamabhethri e-lead-acid.

Lokhu kuminyana kwamandla okuphezulu kuholela ekusebenzeni isikhathi eside ngenkathi ngesikhathi esifanayo kunciphisa isisindo sesistimu yebhethri.

Ukusabela kwamakhemikhali ngaphakathi kwamabhethri e-lead-acid kubangela ukuphuma kwegesi, okudinga ukuthi amabhethri akhishwe futhi ngezikhathi ezithile agcwaliswe kabusha ngamanzi ngumsebenzisi.Uma amabhethri engagcinwa eqondile, isisombululo se-asidi singavuza, kulimaze ibhethri futhi kubangele ukungcola.Kungenjalo, amabhethri e-LFP awayikhiphi igesi futhi awadingi ukushaywa umoya noma ukugcwaliswa kabusha.Okungcono nakakhulu, ungawakhweza kunoma iyiphi umumo.

Amabhethri e-LFP ekuqaleni abiza kakhulu kunamabhethri e-lead-acid.Kodwa-ke, isikhathi eside sempilo yamabhethri e-LFP silinganisa izindleko zawo zangaphambili eziphezulu.Ezimweni eziningi, amabhethri e-LFP azohlala isikhathi eside izikhathi ezi-5-10 kunamabhethri e-lead-acid, okuholela ekongeni kwezindleko zizonke.

Amabhethri Angcono Kakhulu E-Lithium Iron Phosphate Okushintsha Izicelo Zebhethri Le-Lead-Acid

Amabhethri e-lithium-ion amaningi ahlukene ayatholakala, futhi amanye aze adlule i-lithium iron phosphate ezigabeni ezithile zokusebenza.Kodwa-ke, uma kuziwa ekushintsheni amabhethri e-lead-acid angu-12-volt, i-LFP iyindlela engcono kakhulu etholakalayo.

Isizathu esiyinhloko salokhu ukuthi i-voltage yeseli ye-lithium iron phosphate ingu-3.2 volts.Amandla kagesi webhethri angu-12-volt lead-acid angaba ngu-12.7 volts.Ngakho, izintambo ezine zamaseli ochungechungeni ngaphakathi kwebhethri zikhiqiza ama-volts angu-12.8 (4 x 3.2 = 12.8) - cishe ukufana okuphelele!Lokhu akwenzeki nganoma yiluphi olunye uhlobo lwebhethri ye-lithium-ion.

Ngale kokufana kwe-voltage ecishe iphelele, i-LFP inikeza ezinye izinzuzo njengokushintshwa kwe-lead-acid.Njengoba kuxoxiwe ngenhla, amabhethri e-LFP ahlala isikhathi eside, azinzile, aphephile, aqinile, angasindi, futhi anomthamo omkhulu wamandla.Lokhu kubenza bafaneleke kakhulu izinhlelo zokusebenza eziningi!Izinto ezifanaama-trolling motors,Ama-RV,izinqola zegalofu, nezinye izinhlelo zokusebenza ebezithembele kumabhethri e-lead-asidi.

Dragonfly Energy and Battle Born Batteries akha amanye amabhethri e-lithium iron phosphate angcono kakhulu atholakalayo.Zakhiwe ngokuziqhenya futhi zahlanganiswa e-United States ngezinto ezisezingeni eliphezulu ezitholakalayo.Ngaphezu kwalokho, ibhethri ngalinye lihlolwe ngokuqinile futhi lifakwe kuhlu lwe-UL.

Ibhethri ngalinye lihlanganisa nehlanganisiweuhlelo lokuphatha ibhethriukuqinisekisa ukuthi ibhethri lisebenza ngokuphepha ngaphansi kwazo zonke izimo.I-Dragonfly Energy kanye ne-Battle Born Battery inezinkulungwane zamabhethri afakiwe futhi asebenza ngokuphepha ezinhlelweni eziningi ezahlukene emhlabeni jikelele.

Manje usuyazi

Sengiphetha, i-lithium iron phosphate ingenye yezinhlobo eziningi zamabhethri e-lithium-ion atholakalayo.Kodwa-ke, isethi ehlukile yezici ezakha amabhethri e-LFP awenza abe ngenye indlela enhle kumabhethri e-lead-acid angu-12-volt wangaphambilini.
