Ibhetri yamandla ibizwa ngokuba yintliziyo yesithuthi sombane; uphawu, izinto, umthamo, ukhuseleko ukusebenza, njl ibhetri yesithuthi sombane ziye zaba "imilinganiselo" ebalulekileyo kunye "neparameters" yokulinganisa isithuthi sombane. Okwangoku, ixabiso lebhetri yemoto yombane ngokuqhelekileyo i-30% -40% yemoto yonke, enokuthiwa yinto engundoqo!
Okwangoku, iibhetri zamandla aqhelekileyo asetyenziswa kwizithuthi zombane kwimarike zohlulwe ngokubanzi zibe ziindidi ezimbini: iibhetri ze-ternary lithium kunye neebhetri ze-lithium iron phosphate. Okulandelayo, makhe ndihlalutye ngokufutshane umahluko kunye neenzuzo kunye nokungalunganga kwezi bhetri zimbini:
1. Iimathiriyeli ezahlukeneyo:
Isizathu sokuba kuthiwe "i-lithium ye-ternary" kunye ne "lithium iron phosphate" ngokuyintloko ibhekisela kwizinto zekhemikhali "zezinto ezilungileyo ze-electrode" zebhetri yamandla;
"Ternary lithium":
Izinto ze-cathode zisebenzisa i-lithium nickel cobalt manganate (Li (NiCoMn) O2) izinto ze-ternary cathode kwiibhetri ze-lithium. Esi sixhobo sidibanisa iingenelo ze-lithium cobalt oxide, i-lithium nickel oxide kunye ne-lithium manganate, ukwenza inkqubo ye-eutectic yesigaba sesithathu sezinto ezintathu. Ngenxa yesiphumo se-ternary synergistic, ukusebenza kwayo okubanzi kungcono kunayo nayiphi na indibaniselwano enye ikhompawundi.
"Ilithium iron phosphate":
ibhekisela kwiibhetri ze-lithium-ion usebenzisa i-lithium iron phosphate njenge-cathode material. Iimpawu zayo kukuba ayinayo izakhi zetsimbi ezixabisekileyo ezifana ne-cobalt, ixabiso lezinto ezibonakalayo liphantsi, kwaye izibonelelo ze-phosphorus kunye nentsimbi zininzi emhlabeni, ngoko akuyi kubakho iingxaki zokubonelela.
isishwankathelo
Izinto ze-lithium ze-Ternary zinqabile kwaye zinyuka ngokukhula ngokukhawuleza kwezithuthi zombane. Amaxabiso abo aphezulu kwaye athintelwe kakhulu ngezinto eziluhlaza ezinyukayo. Olu luphawu lwe-ternary lithium okwangoku;
I-lithium iron phosphate, kuba isebenzisa umlinganiselo osezantsi wesinyithi/isinyithi esinqabileyo kwaye ixabisa kakhulu kwaye inentsimbi eninzi, inexabiso eliphantsi kuneebhetri ze-lithium ze-ternary kwaye ayichatshazelwa kangako yimathiriyeli ekrwada enyukayo. Olu luphawu lwayo.
2. Ukuxinana kwamandla okwahlukeneyo:
"Ibhetri ye-lithium ye-Ternary": Ngenxa yokusetyenziswa kwezinto zetsimbi ezisebenzayo, ukuxinwa kwamandla eebhetri ze-lithium eziqhelekileyo ngokuqhelekileyo (140wh / kg ~ 160 wh / kg), ephantsi kuneebhetri ze-ternary ezinomlinganiselo ophezulu we-nickel ( 160 wh/kg～180 wh/kg); ubunzima bobunzima bobunzima bunokufikelela kwi-180Wh-240Wh/kg.
"I-Lithium iron phosphate": Ubuninzi bamandla ngokuqhelekileyo yi-90-110 W / kg; ezinye iibhetri ze-lithium iron phosphate, ezifana neebhetri zeblade, zinoxinzelelo lwamandla ukuya kuthi ga kwi-120W/kg-140W/kg.
isishwankathelo
Inzuzo enkulu ye "ternary lithium battery" ngaphezu kwe "lithium iron phosphate" kukuxinana kwamandla aphezulu kunye nesantya sokutshaja ngokukhawuleza.
3. Ukuguquguquka kobushushu okwahlukileyo:
Ukumelana nobushushu obuphantsi:
Ibhetri ye-lithium ye-Ternary: Ibhetri ye-lithium ye-ternary inomsebenzi oncomekayo wobushushu obuphantsi kwaye inokugcina malunga ne-70% ~ 80% yomthamo webhetri yesiqhelo kwi -20°C.
Ilithium iron phosphate: Ayixhathisi kumaqondo obushushu aphantsi: Xa ubushushu bungaphantsi kwe -10°C,
iibhetri ze-lithium iron phosphate zibola ngokukhawuleza. Iibhetri ze-lithium iron phosphate zinokugcina kuphela malunga ne-50% ukuya kwi-60% yomthamo webhetri wesiqhelo kwi -20.°C.
isishwankathelo
Kukho umahluko omkhulu kwiqondo lokushisa phakathi kwe "ternary lithium battery" kunye ne "lithium iron phosphate"; "i-lithium iron phosphate" iyakwazi ukumelana nobushushu obuphezulu; kunye ne-low-temperature-resistant-resistant "ternary lithium battery" inobomi bebhetri obungcono kwiindawo ezisenyakatho okanye ebusika.
4. Ubude bobomi obahlukeneyo:
Ukuba umthamo oseleyo / umthamo wokuqala = 80% usetyenziswa njengendawo yokuphela kovavanyo, uvavanyo:
Iipakethi zebhetri ye-lithium iron phosphate zinobomi bomjikelo obude kuneebhetri ze-lead-acid kunye neebhetri ze-ternary lithium. "Obona bomi bude" kwiibhetri zethu ze-lead-acid ezifakwe kwisithuthi zimalunga namaxesha angama-300 kuphela; ibhetri ye-lithium ye-ternary inokugcina i-theory ukuya kumaxesha angama-2,000, kodwa ekusebenziseni okwenyani, umthamo uya kubola ukuya kuma-60% emva kwamaxesha angama-1,000; kunye nobomi bokwenyani beebhetri ze-lithium iron phosphate ngamaxesha angama-2000, kusekho umthamo we-95% ngeli xesha, kwaye ubomi bomjikelezo wengqiqo bufikelela kumaxesha angaphezu kwama-3000.
isishwankathelo
Iibhetri zamandla ziyincopho yeteknoloji yeebhetri. Zombini iintlobo zeebhetri ze-lithium zinokuqina. Ukuthetha ngokwethiyori, ubomi bebhetri ye-lithium yi-2,000 yentlawulo kunye nemijikelo yokukhupha. Nokuba siyibiza kanye ngemini, inokuhlala ngaphezulu kweminyaka emi-5.
5. Amaxabiso ahlukile:
Ekubeni iibhetri ze-lithium iron phosphate azinazo izinto ezixabisekileyo zetsimbi, iindleko zezinto eziluhlaza zinokuncitshiswa kakhulu. Iibhetri ze-lithium ze-lithium zisebenzisa i-lithium nickel cobalt manganate njengento efanelekileyo ye-electrode kunye negraphite njengento engafanelekanga ye-electrode, ngoko ixabiso libiza kakhulu kuneebhetri ze-lithium iron phosphate.
Ibhetri ye-lithium ye-ternary ikakhulu isebenzisa imathiriyeli ye-ternary cathode ye "lithium nickel cobalt manganate" okanye "i-lithium nickel cobalt aluminate" njenge-electrode elungileyo, ikakhulu isebenzisa ityuwa yenickel, ityuwa ye-cobalt, kunye netyuwa yemanganese njengemathiriyeli ekrwada. "Into ye-cobalt" kwezi zimbini ze-cathode izinto ziyintsimbi exabisekileyo. Ngokutsho kwedatha evela kwiiwebhusayithi ezifanelekileyo, ixabiso lereferensi yasekhaya yensimbi ye-cobalt yi-413,000 yuan / ton, kunye nokunciphisa izinto eziphathekayo, ixabiso liyaqhubeka nokunyuka. Okwangoku, iindleko zeebhetri ze-lithium ze-ternary yi-0.85-1 yuan / i-wh, kwaye ngoku ikhula ngokufunwa kweemarike; iindleko ze-lithium iron phosphate iibhetri ezingenazo izinto zetsimbi ezixabisekileyo zimalunga ne-0.58-0.6 yuan / wh kuphela.
isishwankathelo
Ekubeni "i-lithium iron phosphate" ayinayo isinyithi esixabisekileyo njenge-cobalt, ixabiso layo liyi-0.5-0.7 kuphela ngamaxesha eebhetri ze-lithium ze-ternary; ixabiso cheap luyinzuzo enkulu lithium iron phosphate.
Shwankathela
Isizathu sokuba kutheni iimoto zombane ziye zakhula kwiminyaka yakutshanje kwaye zimele isalathiso sekamva lophuhliso lweemoto, ukunika abathengi amava angcono kakhulu, kungenxa yophuhliso oluqhubekayo lobuchwepheshe bebhetri yamandla.
