Ibhetri yamandla ibizwa ngokuba yintliziyo yesithuthi sombane; uphawu, izinto ezisetyenziswayo, umthamo, ukusebenza kokhuseleko, njl.njl. kwebhetri yesithuthi sombane kuye kwaba "bubukhulu" kunye "neeparameter" ezibalulekileyo zokulinganisa isithuthi sombane. Okwangoku, ixabiso lebhetri yesithuthi sombane ngokubanzi liyi-30%-40% yesithuthi siphela, nto leyo enokuthiwa sisixhobo esiphambili!
Okwangoku, iibhetri zamandla eziphambili ezisetyenziswa kwizithuthi zombane ezithengiswayo ngokubanzi zahlulwe zibe ziintlobo ezimbini: iibhetri ze-ternary lithium kunye neebhetri ze-lithium iron phosphate. Okulandelayo, makhe ndihlalutye ngokufutshane umahluko kunye neengenelo kunye nokungalungi kwezi bhetri zimbini:
1. Izixhobo ezahlukeneyo:
Isizathu sokuba ibizwa ngokuba yi-"ternary lithium" kunye ne-"lithium iron phosphate" ikakhulu ibhekisa kwizinto zeekhemikhali ze "positive electrode material" yebhetri yamandla;
"I-lithium yeTernary":
Izinto ze-cathode zisebenzisa izinto ze-lithium nickel cobalt manganate (Li(NiCoMn)O2) ternary cathode kwiibhetri ze-lithium. Ezi zinto zidibanisa iingenelo ze-lithium cobalt oxide, i-lithium nickel oxide kunye ne-lithium manganate, zenze inkqubo ye-eutectic yezigaba ezintathu zezinto ezintathu. Ngenxa yesiphumo se-ternary synergistic, ukusebenza kwayo okubanzi kungcono kunayo nayiphi na i-compound enye edibeneyo.
"I-Lithium iron phosphate":
ibhekisa kwiibhetri ze-lithium-ion ezisebenzisa i-lithium iron phosphate njengezinto ze-cathode. Iimpawu zayo kukuba ayinazo izinto zesinyithi ezixabisekileyo ezifana ne-cobalt, ixabiso lezinto eziluhlaza liphantsi, kwaye imithombo ye-phosphorus kunye ne-iron ininzi emhlabeni, ngoko ke akuyi kubakho ngxaki yokubonelela.
isishwankathelo
Izinto ze-lithium ze-ternary zinqabile kwaye ziyanda ngophuhliso olukhawulezayo lwezithuthi zombane. Amaxabiso azo aphezulu kwaye zithintelwe kakhulu zizinto eziluhlaza eziphezulu. Olu luphawu lwe-lithium ye-ternary okwangoku;
I-lithium iron phosphate, kuba isebenzisa umlinganiselo ophantsi weentsimbi ezinqabileyo/ezixabisekileyo kwaye ikakhulu ixabisa kancinci kwaye ininzi kakhulu, ixabisa kancinci kuneebhetri ze-ternary lithium kwaye ayichaphazeleki kakhulu zizinto eziluhlaza ezikumgangatho ophezulu. Olu luphawu lwayo.
2. Ubuninzi bamandla obahlukeneyo:
"Ibhetri ye-lithium yeTernary": Ngenxa yokusetyenziswa kwezinto zesinyithi ezisebenzayo ngakumbi, uxinano lwamandla lweebhetri ze-lithium ze-ternary eziqhelekileyo luhlala luyi (140wh/kg ~ 160 wh/kg), oluphantsi kunolo lweebhetri ze-ternary ezine-nickel ratio ephezulu (160 wh/kg).～180 wh/kg); ubunzima obuthile bobunzima bunokufikelela kwi-180Wh-240Wh/kg.
"I-Lithium iron phosphate": Uxinano lwamandla ngokubanzi luyi-90-110 W/kg; ezinye iibhetri ze-lithium iron phosphate ezintsha, ezifana neebhetri zeblade, zinoxinano lwamandla olufikelela kwi-120W/kg-140W/kg.
isishwankathelo
Eyona nzuzo inkulu ye "ternary lithium battery" kune "lithium iron phosphate" kukuxinana kwayo kwamandla aphezulu kunye nesantya sokutshaja esikhawulezayo.
3. Ukuguquguquka kobushushu obahlukeneyo:
Ukumelana nobushushu obuphantsi:
Ibhetri ye-lithium ye-Ternary: Ibhetri ye-lithium ye-Ternary isebenza kakuhle kakhulu kubushushu obuphantsi kwaye inokugcina malunga ne-70% ~ 80% yomthamo webhetri oqhelekileyo kwi -20°C.
I-lithium iron phosphate: Ayimelani namaqondo obushushu aphantsi: Xa amaqondo obushushu engaphantsi 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 oqhelekileyo kwi--20°C.
isishwankathelo
Kukho umahluko omkhulu ekuzivumelaniseni nobushushu phakathi "kwebhetri ye-ternary lithium" kunye "ne-lithium iron phosphate"; "i-lithium iron phosphate" iyakwazi ukumelana nobushushu obuphezulu; kwaye "ibhetri ye-ternary lithium" ekwazi ukumelana nobushushu obuphantsi inobomi obungcono bebhetri kwiindawo ezisemantla okanye ebusika.
4. Amaxesha obomi ahlukeneyo:
Ukuba umthamo oseleyo/umthamo wokuqala = 80% usetyenziswa njengendawo yokugqibela yovavanyo, vavanya:
Iibhetri ze-lithium iron phosphate zinobomi obude bomjikelo kuneebhetri ze-lead-acid kunye neebhetri ze-ternary lithium. "Ubomi obude" beebhetri zethu ze-lead-acid ezifakwe kwisithuthi bumalunga namaxesha angama-300 kuphela; ibhetri ye-ternary lithium inokuhlala ukuya kuthi ga kwi-2,000 ngokwethiyori, kodwa xa isetyenziswa ngokwenene, amandla ayo aya kubola aye kwi-60% emva kwamaxesha amalunga ne-1,000; kwaye ubomi bokwenyani beebhetri ze-lithium iron phosphate bungama-2000, kusekho amandla angama-95% okwangoku, kwaye ubomi bomjikelo wayo oqikelelweyo bufikelela ngaphezu kwamaxesha angama-3000.
isishwankathelo
Iibhetri zamandla zezona zibalaseleyo kwiibhetri. Zombini ezi ntlobo zeebhetri ze-lithium zihlala ixesha elide. Ngokwethiyori, ubomi bebhetri ye-ternary lithium yi-2,000 charge kunye ne-discharge cycles. Nokuba siyitshaja kube kanye ngemini, inokuhlala iminyaka engaphezu kwemi-5.
5. Amaxabiso ahlukile:
Ekubeni iibhetri ze-lithium iron phosphate zingenazo izinto zesinyithi ezixabisekileyo, ixabiso lezinto eziluhlaza lingancitshiswa kakhulu. Iibhetri ze-lithium ze-Ternary zisebenzisa i-lithium nickel cobalt manganate njengezinto ze-electrode ezilungileyo kunye ne-graphite njengezinto ze-electrode ezimbi, ngoko ke ixabiso libiza kakhulu kuneebhetri ze-lithium iron phosphate.
Ibhetri ye-ternary lithium isebenzisa kakhulu izinto ze-ternary cathode ze-"lithium nickel cobalt manganate" okanye "lithium nickel cobalt aluminate" njenge-electrode elungileyo, ikakhulu isebenzisa ityuwa ye-nickel, ityuwa ye-cobalt, kunye netyuwa ye-manganese njengezinto eziluhlaza. "I-cobalt element" kwezi zinto zimbini ze-cathode yintsimbi exabisekileyo. Ngokwedatha evela kwiwebhusayithi ezifanelekileyo, ixabiso lasekhaya le-cobalt metal yi-413,000 yuan/ton, kwaye ngokuncipha kwezinto, ixabiso liyaqhubeka nokunyuka. Okwangoku, ixabiso leebhetri ze-ternary lithium yi-0.85-1 yuan/wh, kwaye okwangoku liyanda ngokwemfuno yemarike; ixabiso leebhetri ze-lithium iron phosphate ezingenazo izinto zesinyithi ezixabisekileyo limalunga ne-0.58-0.6 yuan/wh kuphela.
isishwankathelo
Ekubeni "i-lithium iron phosphate" ingenazo izinyithi ezixabisekileyo ezifana ne-cobalt, ixabiso layo liphindwe kayi-0.5-0.7 kuphela kuneebhetri ze-ternary lithium; ixabiso eliphantsi liyinzuzo enkulu ye-lithium iron phosphate.
Shwankathela
Isizathu sokuba izithuthi zombane ziphumelele kwiminyaka yakutshanje kwaye zimele indlela ezayo yophuhliso lweemoto, nto leyo enika abathengi amava angcono ngakumbi, ikakhulu kungenxa yophuhliso oluqhubekayo lwetekhnoloji yebhetri yamandla.
