Yintoni iLithium Iron Phosphate?

Kuyinto eqhelekileyo ukuba iibhetri ze-lithium iron phosphate zihluke kuneebhetri ze-lithium-ion.Enyanisweni, zininzi iintlobo zeebhetri ze-lithium-ion, kwaye i-lithium iron phosphate yenye yazo.

Makhe sijonge ukuba yintoni kanye kanye i-lithium iron phosphate, kutheni ilukhetho olukhulu kwiintlobo ezithile zeebhetri, kwaye ithelekisa njani nezinye iinketho zebhetri ye-lithium-ion.

Yintoni iLithium Iron Phosphate?

I-Lithium iron phosphate yikhemikhali ye-LiFePO4 okanye "LFP" ngokufutshane.I-LFP inika ukusebenza kakuhle kwe-electrochemical, ukuchasana okuphantsi kwaye yenye yezona zinto zikhuselekileyo kunye nezizinzileyo ze-cathode izixhobo ezikhoyo kwiibhetri ze-lithium-ion.

Yintoni ibhetri yeLithium Iron Phosphate?

Iibhetri ze-lithium iron phosphate luhlobo lwebhetri ye-lithium-ion esebenzisa i-lithium iron phosphate njenge-cathode impahla yokugcina i-lithium ion.Iibhetri ze-LFP zihlala zisebenzisa igraphite njengesixhobo se-anode.Ukwenziwa kweekhemikhali zeebhetri ze-LFP zibanika umlinganiselo ophezulu wangoku, uzinzo oluhle lwe-thermal, kunye nobomi obude.

Uninzi lweebhetri ze-lithium iron phosphate zineeseli ezine zebhetri ezifakwe kwiintambo kuthotho.Umbane oqhelekileyo weseli yebhetri ye-LFP yi-3.2 volts.Ukuqhagamshela iiseli ezine zebhetri ze-LFP kwiziphumo ezilandelelanayo kwi-12-volt ibhetri eyona ndlela ibalaseleyo yokutshintsha iibhetri ezininzi ze-12-volt lead-acid.

ILithium Iron Phosphate Vs.Iintlobo ezizezinye zeLithium-Ion

I-lithium iron phosphate yenye nje yeentlobo ezininzi zeebhetri ze-lithium-ion.Ukutshintsha ikhompawundi yemichiza yecathode kudala iintlobo ezahlukeneyo zeebhetri ze-lithium-ion.Ezinye zezona zikhetho eziqhelekileyo ziyi-Lithium Cobalt Oxide (LCO), iLithium Manganese Oxide (LMO), iLithium Nickel Cobalt Aluminium Oxide (NCA), iLithium Nickel Manganese Cobalt Oxide (NMC), kunye neLithium Titanate (LTO).

Nganye kwezi ntlobo zebhetri zinamandla ahlukeneyo kunye nobuthathaka obenza ukuba balungele izicelo ezahlukeneyo.Ukujonga kwiipropati eziphambili zezi ntlobo zebhetri, sinokubona apho iibhetri ze-lithium iron phosphate zime kwaye zeziphi izicelo ezingcono kakhulu.

Ukuxinana kwamandla

Iibhetri ze-LFP zinelinye lawona mlinganiselo uphezulu wamandla athile phakathi kwezinye iindidi ze-lithium-ion.Ngamanye amazwi, amandla athile aphezulu athetha ukuba iibhetri ze-LFP zinokunikezela ngezixa eziphezulu zangoku kunye namandla ngaphandle kokufudumeza.

Kwelinye icala, kubalulekile ukukhumbula ukuba iibhetri ze-LFP zinelinye lawona mlinganiselo uphantsi wamandla athile.Amandla athile aphantsi athetha ukuba iibhetri ze-LFP zinomthamo omncinci wokugcina amandla ngobunzima kunezinye iinketho ze-lithium-ion.Oku ayisiyonto inkulu kuba ukonyusa umthamo webhanki yebhetri kunokwenziwa ngokuqhagamshela iibhetri ezininzi ngaxeshanye.Oku kunokungalungeli usetyenziso apho uxinano lwamandla agqithileyo kwindawo ekhaphukhaphu kakhulu kufuneka, njengeebhetri zezithuthi zombane.

Imijikelo yoBomi bebhetri

Iibhetri ze-lithium iron phosphate zinexesha lokuphila eliqala malunga ne-2,000 imijikelo yokukhupha ngokupheleleyo kwaye inyuke ngokuxhomekeke kubunzulu bokukhupha.Iiseli kunye nenkqubo yolawulo lwebhetri yangaphakathi (i-BMS) esetyenziswa kwi-Dragonfly Energy ziye zavavanywa ukuya kwimijikelo engaphezulu kwama-5,000 yokukhupha ngokupheleleyo ngelixa zigcina i-80% yomthamo webhetri yokuqala.

I-LFP yeyesibini kuphela kwi-lithium titanate ebomini.Nangona kunjalo, iibhetri ze-LTO ngokwesiko ibiyeyona ibiza kakhulu ibhetri ye-lithium-ion, ibenza ukuba bangabizi kakhulu kwizicelo ezininzi.

Ireyithi yokukhupha

Izinga lokukhutshwa lilinganiswa ngokuphindaphindiweyo komthamo webhetri, okuthetha ukuba ireyithi yokukhupha i-1C yebhetri eyi-100Ah yi-100A eqhubekayo.Iibhetri ze-LFP ezifumaneka ngokurhweba ngokwesiko zine-1C yokukhutshwa ngokuqhubekayo kodwa zinokudlula oku kwixesha elifutshane ngokuxhomekeke kwinkqubo yokulawula ibhetri.

Iiseli ze-LFP ngokwazo zinokubonelela ngokukhutshwa kwe-25C ixesha elifutshane ngokukhuselekileyo.Ukukwazi ukudlula i-1C kukuvumela ukuba usebenzise iibhetri ze-LFP kwizicelo ezinamandla kakhulu ezinokuthi zibe ne-spikes zokuqalisa kwi-draw yangoku.

Ubushushu bokusebenza

Iibhetri ze-LFP azingeni kwiimeko zokubaleka kwe-thermal kude kube malunga ne-270 degrees Celsius.Xa kuthelekiswa nezinye iinketho zebhetri ze-lithium-ion eziqhelekileyo, iibhetri ze-LFP zinomlinganiselo wesibini ophezulu weqondo lokushisa.

Ukugqithisa umda weqondo lokushisa kwibhetri ye-lithium-ion kubangela umonakalo kwaye kunokukhokelelaukubaleka kwe-thermal, ekusenokwenzeka ukuba kubangele umlilo.Umda ophezulu wokusebenza we-LFP unciphisa kakhulu ithuba lesiganeko sokubaleka kwe-thermal.Idityaniswe ne-BMS ekumgangatho ophezulu ukuvala iiseli kakuhle phambi kwezi meko (malunga ne-57 degrees Celsius), i-LFP inikezela ngezibonelelo ezibalulekileyo zokhuseleko.

Ukhuseleko oluluncedo

Iibhetri ze-LFP yenye yeekhemistri ezizinzileyo kuzo zonke iinketho ze-lithium-ion.Olu uzinzo lubenza lube lolona khetho lukhuselekileyo kubo bobabini abajongana nabathengi kunye nezicelo zoshishino.

Olunye ukhetho olukhuselekileyo oluthelekisekayo yi-lithium titanate, ephinda ingabiziindleko kwaye ayisebenzi kumbane ochanekileyo kwiimeko ezininzi zokutshintshwa kwe-12V.

ILithium Iron Phosphate Vs.Iibhetri zeLead-Acid

Iibhetri zeLithium iron phosphate zinika ezininziiingenelo ngaphezu iibhetri lead-asidi zemveli.Eyona nto iphawuleka kakhulu kukuba iibhetri ze-LFP zinokuphinda-phindwe kane ukuxinwa kwamandla kweebhetri ze-lead-acid.Unokwenza iibhetri ze-LFP ezinzulu ngokuphindaphindiweyo ngaphandle kokuzonzakalisa.Baphinde batshaje i-5 ngokukhawuleza kuneebhetri ze-lead-asidi.

Oku kuxinana kwamandla aphezulu kukhokelela kwixesha elide lokubaleka ngelixa ngaxeshanye kunciphisa ubunzima benkqubo yebhetri.

Ukusabela kweekhemikhali ngaphakathi kweebhetri ze-lead-asidi kubangela ukuphuma kwegesi, nto leyo efuna ukuba iibhetri zifakwe umoya kwaye ngamaxesha athile zizaliswe ngamanzi ngumsebenzisi.Ukuba iibhetri azigcinwanga ngokuthe tye, isisombululo se-asidi sinokuvuza, sonakalise ibhetri kwaye sibangele ukungcola.Kungenjalo, iibhetri ze-LFP azicimi kwigesi kwaye akufuneki ukuba zifakwe umoya okanye zizaliswe kwakhona.Ngcono nangakumbi, ungazikhwelisa kulo naluphi na uqhelaniso.

Iibhetri ze-LFP ekuqaleni zibiza kakhulu kuneebhetri ze-lead-asidi.Nangona kunjalo, ubomi obude beebhetri ze-LFP zilinganisa iindleko zabo eziphezulu.Kwiimeko ezininzi, iibhetri ze-LFP ziya kuhlala amaxesha angama-5-10 ubude kuneebhetri ze-lead-asidi, okukhokelela kukongiwa kweendleko ngokubanzi.

Eyona bhetri yeLithium ye-Iron Phosphate yokuTshintsha usetyenziso lwebhetri ye-Lead-Acid

Iibhetri ezininzi ze-lithium-ion ziyafumaneka, kwaye ezinye zide zidlule i-lithium iron phosphate kwiindidi ezithile zokusebenza.Nangona kunjalo, xa kuziwa ekutshintsheni iibhetri ze-12-volt lead-acid, i-LFP yeyona ndlela ilungileyo ekhoyo.

Isizathu esiphambili soku kukuba i-voltage yeseli ye-lithium ye-iron phosphate yi-3.2 volts.I-voltage yegama le-12-volt lead-acid ibhetri imalunga ne-12.7 volts.Ngaloo ndlela, ii-wiring iiseli ezilandelelanayo ngaphakathi kwebhetri zivelisa i-12.8 volts (4 x 3.2 = 12.8) - phantse umdlalo ogqibeleleyo!Oku akunakwenzeka nangaluphi na olunye uhlobo lwebhetri ye-lithium-ion.

Ngaphaya komdlalo ophantse ugqibelele wombane, i-LFP ibonelela ngezinye izibonelelo njengotshintsho lwe-lead-acid.Njengoko kuxoxiwe ngasentla, iibhetri ze-LFP zihlala ixesha elide, zizinzile, zikhuselekile, ziqinile, zikhaphukhaphu, kwaye zinezinga eliphezulu lokuxinana kwamandla.Oku kubenza balunge kakhulu kwizicelo ezininzi!Izinto ezifanaiimotor ezijikelezayo,Ii-RVs,iinqwelo zegalufa, kunye nezicelo ezininzi eziye zathembela ngokwesiko kwiibhetri ze-lead-acid.

I-dragonfly Energy kunye neeBattery ezizalelwa kwidabi zakha ezona bhetri ze-lithium iron phosphate zikhoyo.Ziyilwe ngokuzingca zadityaniswa eUnited States ngezona zixhobo zikumgangatho ophezulu ezikhoyo.Ukongeza, ibhetri nganye ivavanywa ngokungqongqo kwaye i-UL idweliswe.

Ibhetri nganye ikwabandakanya indibaniselwanoinkqubo yokulawula ibhetriukuqinisekisa ukuba ibhetri isebenza ngokukhuselekileyo phantsi kwazo zonke iimeko.I-dragonfly Energy kunye neBattle Born Battery zinamawaka eebhetri ezifakiweyo kwaye zisebenza ngokukhuselekileyo kwizicelo ezininzi ezahlukeneyo kwihlabathi liphela.

Ngoku Uyazi

Ukuqukumbela, i-lithium iron phosphate yenye nje yeentlobo ezininzi ezahlukeneyo zeebhetri ze-lithium-ion ezikhoyo.Nangona kunjalo, iiseti ezikhethekileyo zeempawu ezenza iibhetri ze-LFP zibenza ibe yinto emnandi kwiibhetri ze-12-volt ze-asidi zexesha elidlulileyo.
