Ziziphi iingenelo zeebhetri zeSolar LiFePo4?

Ukuqulunqwa kweSolarLiFePo4ibhetri Uphawu olulodwa lweibhetri yelanga yeLiFePo4(ibhetri ye-lithium ye-phosphate yentsimbi) kukusetyenziswa kwesakhiwo sekristale yomnquma, ikristale yimilo emva kwecrystallization, yahlulwe yaba yi-ionic / molecular / atomic / crystal yentsimbi, i-lithium-ion yebhetri ye-ionic crystal ithathwa kwizinto zayo ze-cathode kulungiselelo lwee-ionic compounds. kwimilo yentsingiselo, oko kukuthi, ngeqela le-ion elilungileyo nelibi kumyinge othile wekristale eyenziwe yi-ionic bonding. Ngokuqhelekileyo, iikristale ze-ionic zi-brittle kwaye ziqinile, zineempawu eziphezulu zokunyibilika kunye neendawo zokubilisa, kwaye zinokuqhuba umbane xa unyibilikile okanye unyibilikile. Isiseko sazo zonke iibhetri ze-lithium-ion, kuquka iteknoloji ye-lithium iron phosphate, i-ionic conductivity. Uninzi lwesakhiwo sekristale yangaphakathi yecathode yebhetri ye-lithium-ion ithatha "isakhiwo somgogodla", i-lithium manganate, i-lithium cobaltate, iibhetri ze-lithium ze-ternary zinjalo, esi sakhiwo sineeyunithi ezisibhozo ezincinci ze-cubic ezenziwe ngeeseli ze-spinel (iiyunithi ezenza phezulu kwekristale, inokuqondwa ngokwenyani njengeeseli zekristale), iiseli zidityaniswa kwisakhiwo sekristale ye-octahedral. Ngokwahlukileyo, isakhiwo somnquma se-lithium iron phosphate crystals ziintsika ezimfutshane. Isakhiwo se-spinel sezi bhetri ze-lithium ezingentla zineempawu zazo. Iibhetri ze-lithium cobalt-acid zinomsebenzi obalaseleyo jikelele, kodwa umthamo ophantsi kunye neengxaki zokhuseleko, kwaye zibiza kakhulu ukuthengisa; iibhetri ze-lithium manganate ngenxa yokufikelela kakuhle kwizinto eziphathekayo, iindleko eziphantsi kunye nokhuseleko, kodwa ukusebenza komjikelo ombi kunye nokusebenza kokugcina; iibhetri ternary lithium zenzelwe ukulungelelanisa iintsilelo ezimbini, umthamo liye landa, kwaye uzinzo lwesakhiwo luphucule ukhuseleko, kodwa ixabiso lisabiza kakhulu, kuba lifuna i-cobalt yobuchule. Ukungalungi ngokubanzi kwe-spinelibhetri ye-lithium-ionkukuba amandla akakhulu, awafanelekanga ubukhulu. Zeziphi iimpawu zeebhetri zeSolar LiFePo4? Iimpawu zetekhnoloji yebhetri yeSolar LiFePo4 kunye noqoqosho, kwelinye icala, ilungile kwimeko yogcino lwamandla ekhaya. Ngokuthe ngqo. 1. I-voltage ye-solar LiFePo4 yebhetri iphakathi: i-voltage ye-nominal 3.2V, i-voltage yokutshaja yokuphelisa i-3.6V, i-termination discharge voltage 2.0V. 2. umthamo ophezulu wethiyori, kunye noxinzelelo lwamandla lwe-170mAh / g. 3. ukuzinza okuhle kwe-thermal kunye nokumelana nokushisa okuphezulu. 4. ukugcinwa kwamandla okuphakathi, izinto ze-cathode ezihambelana neenkqubo ezininzi ze-electrolyte. 5. Ukuphelisa i-voltage ye-2.0V, ekwazi ukukhupha umthamo ongaphezulu, ukukhutshwa okukhulu kunye nokulinganisela. 6. Iimpawu zeqonga lamandla ombane ezilungileyo, kunye nebhalansi yeqonga layo lokutshaja kunye nokukhupha amandla ombane lingasondela kumbane olawulwayo. Ezi mpawu zobugcisa zingentla zenza amandla aphezulu kunye nokhuseleko lulungele ukufezekisa, olukhuthaza kakhulu ukusetyenziswa kwebhetri enkulu ye-LiFePo4. Ukongeza kwiimpawu zobugcisa, iibhetri zeLiFePo4 zineenzuzo ezimbini ezithengiswayo: 1. izinto ezingabizi kakhulu, izixhobo ezininzi; 2. ayinayo isinyithi esixabisekileyo, i-non-toxic, imveliso ehambelana nokusingqongileyo. Oku kwenza ukusetyenziswa kwebhetri ye-lithium ye-iron phosphate kwimarike yangoku yemoto yamandla entsha iqaqambe, kwaye ibe yeyona nto ikhethwayo yokugcina amandla kwiinkqubo zokugcina ilanga lasekhaya. ISolar Lithium iron Phosphate kunye neLithium Manganate, iLithium Cobaltate, iTernary Lithium iBattery Comparison I-LiFePo4ibhetri kunye ne-lithium manganate, i-lithium cobaltate, iibhetri ze-lithium ternary zifana nesebe leebhetri ze-lithium-ion, ukusebenza kwayo kusebenza ngokukodwa kwizicelo zamandla elanga, ezibizwa ngokuba yi-solar lithium iron phosphate ibhetri, eyaziwa ngokuba yi-lithium-iron ibhetri. Ke ngoko, iingenelo ze-solar lithium iron phosphate ibhetri ikakhulu ibhekisa ekuthelekisweni kwayo nezinye iibhetri kwizicelo zokugcina amandla. Ngaloo ndlela, iya kuthelekisa ubukhulu becala izibonelelo zayo ezihambelanayo kunye neebhetri ze-lithium ze-ternary kunye neebhetri ze-lead-acid. Okokuqala, inzuzo yokumelana nobushushu obuphezulu xa kuthelekiswa neebhetri ze-lithium ze-ternary. Iibhetri zeSolarLiFePo4 zinobushushu obungcono bokusebenza, zinokumelana namaqondo obushushu aphezulu angama-350 ° C ~ 500 ° C, ngelixa i-lithium manganate / i-lithium cobaltate ihlala imalunga ne-200 ° C kuphela, izixhobo zebhetri ze-lithium ezilungisiweyo nazo ziya kuba malunga ne-200 ° C ukubola. Okwesibini, abathathu phakathi "kwabadala" - inzuzo epheleleyo yobomi obude. Iibhetri ze-lithium iron phosphate kuneebhetri ze-lead-asidi kunye neebhetri ze-ternary ze-lithium zinobomi obude bomjikelezo. Iibhetri ze-lead-acid "kubomi obude" malunga namaxesha angama-300 kuphela, ukuya kuma-500 amaxesha; iibhetri ze-lithium ze-ternary ngokwethiyori ukuya kumaxesha angama-2000, esona sicelo sifikelela kumaxesha angama-1000 umthamo uya kubola ukuya kuma-60%; kunye ne-lithium iron phosphate ubomi bokwenene bebhetri ukuba amaxesha angama-2000, xa kusekho i-95% yomthamo, ingcamango yobomi bomjikelo ngakumbi Finyelela amaxesha angaphezu kwama-3000. Xa kuthelekiswa neebhetri zeLead-asidi zineenzuzo ezininzi 1. Umthamo omkhulu.I-Monomer inokwenziwa kwi-5Ah ~ 1000 Ah (1 Ah = 1000m Ah), ngelixa ibhetri ye-lead-acid 2V monomer idla ngokuba yi-100Ah ~ 150 Ah, uluhlu lokutshintsha luncinci. 2. Ubunzima obulula.Umthamo ofanayo we-solar LiFePo4 umthamo webhetri yi-2/3 yomthamo weebhetri ze-lead-acid, ubunzima buyi-1/3 yokugqibela. 3. Ukutshaja ngokukhawuleza ukukwazi.I-Solar LiFePo4 ibhetri yokutshaja ngoku ukuya kwi-1C, ukufezekisa izinga elikhulu lokutshaja; I-lead-asidi yebhetri yangoku ifunwa ngokubanzi phakathi kwe-0.1C ~ 0.2C, ayikwazi ukufikelela ekusebenzeni kokutshaja ngokukhawuleza. 4. Ukhuseleko lokusingqongileyo. Iibhetri ze-Lead-acid zikhona kubuninzi besinyithi esinzima - ilothe, ivelisa ulwelo olulahlwayo, ngelixa iibhetri ze-solar LiFePo4 aziqulathanga naziphi na iintsimbi ezinzima, akukho ngcoliseko kwimveliso kunye nokusetyenziswa. 5. Ukusebenza kweendleko eziphezulu.Nangona iibhetri ze-lead-acid ngenxa yezixhobo zayo ezincinci, iindleko zokufumana ziphantsi kuneebhetri ze-solar LiFePo4, kodwa kubomi benkonzo kunye nokugcinwa kwesiqhelo kwezoqoqosho kuncinci kuneebhetri ze-solar LiFePo4. Iziphumo zesicelo ezisebenzayo zibonisa ukuba: ibhetri ye-lithium yentsimbi ye-phosphate yelanga ingaphezulu kokuphindwe kane kweendleko zokusebenza kweebhetri ze-lead-acid. Usetyenziso lweSolar LiFePo4battery ngokuqinisekileyo lukwicala leukugcinwa kwamandla, egqitywe ziinzuzo ezahlukeneyo eziboniswe kolu thelekiso lungasentla, ukuba ukuxinana kwamandla kunye nokukhupha i-multiplier kunye neminye imiba kwaye wenze into yokuphucula, i-lithium iron phosphate yelanga iya kubaukhetho lokugcina amandla osapho!
