Xa uthenga izibane zesitalato zelanga,abavelisi bezibane zelangarhoqo ucela abathengi ulwazi olunokunceda ekumiseleni ulungelelwaniso olufanelekileyo lwezinto ezahlukeneyo. Umzekelo, inani leentsuku zemvula kwindawo yokufakela lidla ngokusetyenziswa ukumisela umthamo webhetri. Kule meko, iibhetri ze-lead-acid zithathelwa indawo kancinci kancinci ziibhetri ze-lithium iron phosphate. Zihlala zithathwa njengezingcono, kodwa zithini iingenelo zeebhetri ze-lithium iron phosphate? Apha, umenzi wezibane zelanga uTIANXIANG wabelana ngokufutshane ngembono yakhe.
1. Iibhetri zeLithium:
Iibhetri ze-lithium iron phosphate ngokungathandabuzekiyo zingcono kuneebhetri ze-lead-acid kuzo zonke iinkalo zokusebenza. Okwangoku, uhlobo oluqhelekileyo yi-lithium iron phosphate. Ngokungafaniyo neebhetri ze-lead-acid, ezinengxaki yememori, zinokugcina i-85% yamandla azo okugcina emva kokutshaja ngaphezulu kwe-1,600. Xa kuthelekiswa neebhetri ze-lead-acid, iibhetri ze-lithium zibonelela ngeenzuzo ezifana nokukhanya, amandla aphezulu, kunye nobomi obude.
2. Iibhetri ze-lead-acid:
Ii-electrode zenziwe ngokuyintloko nge-lead kunye ne-oxides, kwaye i-electrolyte sisisombululo se-sulfuric acid. Xa ibhetri ye-lead-acid itshajwa, i-electrode echanekileyo yenziwe ngokuyintloko yi-lead dioxide, kwaye i-electrode engalunganga yenziwe ngokuyintloko yi-lead. Xa ikhutshwa, zombini ii-electrode ezichanekileyo nezingalunganga zenziwe ngokuyintloko yi-lead sulfate. Ngenxa yempembelelo yememori, iibhetri ze-lead-acid zifumana ukwehla okukhulu kumthamo wokugcina emva kokuba zitshajwe ngaphezulu kwezihlandlo ezingama-500.
Ngenxa yesi sizathu, abathengi abaninzi bathanda kakhulu izibane zesitalato zelanga zebhetri ye-lithium yeBaoding. Oku kuchaza ukuthandwa okukhulayo kwezibane zesitalato zelanga zebhetri ye-lithium.
3. Kutheni Abantu Abaninzi BekhethaIzibane zesitalato zeLithium zeSolar?
a. Iibhetri zeLithium zincinci kwaye zikhaphukhaphu, nto leyo egcina ixesha kunye nomgudu wokufakelwa.
Okwangoku, isibane sesitalato selanga esithandwayo kwihlabathi liphela siluhlobo oludibeneyo. Ukuba kusetyenziswa ibhetri ye-lead-acid, kufuneka igqunywe phantsi komhlaba ijikeleze ipali yesibane kwibhokisi engaphantsi komhlaba. Nangona kunjalo, iibhetri ze-lithium, ngenxa yobunzima bazo obulula, zinokwakheka emzimbeni wokukhanya, oko konga ixesha kunye nomgudu.
b. Iibhetri zeLithium azingcolisi kakhulu kwaye zinobuhlobo nokusingqongileyo kuneebhetri zeLead-acid.
Sonke siyazi ukuba iibhetri ze-lead-acid zihlala ixesha elifutshane. Nangona zingabizi kakhulu, zinokufuna ukutshintshwa rhoqo emva kweminyaka embalwa, nto leyo eyonyusa kakhulu ungcoliseko lokusingqongileyo. Iibhetri ze-lead-acid zingcolisa kakhulu kuneebhetri ze-lithium. Ukutshintshwa rhoqo kuya kubangela umonakalo oqhubekayo kwindalo. Iibhetri ze-lithium azingcolisi, ngelixa iibhetri ze-lead-acid zingcoliswa yi-lead yesinyithi esinzima.
c. Iibhetri zeLithium zikrelekrele ngakumbi.
Iibhetri ze-lithium zanamhlanje ziya zisiba krelekrele ngakumbi, zineempawu eziphucukileyo ngakumbi. Ezi bhetri zinokulungiswa ngokusekwe kwiimfuno zomsebenzisi kunye nexesha lokusetyenziswa. Iibhetri ezininzi ze-lithium zinokuxhotyiswa ngenkqubo yolawulo lwebhetri (i-BMS), evumela abasebenzisi ukuba babone imeko yebhetri ngexesha langempela kwiifowuni zabo kwaye bajonge ngokuzimeleyo amandla ebhetri kunye nombane. Ukuba kukho naziphi na iingxaki ezenzekayo, i-BMS ilungisa ibhetri ngokuzenzekelayo.
d. Iibhetri zeLithium zihlala ixesha elide.
Iibhetri ze-lead-acid zinobomi bomjikelo omalunga nemijikelo engama-300. Iibhetri ze-lithium iron phosphate, kwelinye icala, zinobomi bomjikelo we-3C ongaphezu kwemijikelo engama-800.
e. Iibhetri zeLithium zikhuselekile kwaye azinawo umphumo wememori.
Iibhetri ze-lead-acid zichaphazeleka kukungena kwamanzi, ngelixa iibhetri ze-lithium zichaphazeleka kancinci. Ngaphezu koko, iibhetri ze-lead-acid zinefuthe lememori. Oku kwenzeka xa zitshajwa ngaphambi kokuba zikhutshwe ngokupheleleyo, nto leyo enciphisa ubomi bebhetri. Iibhetri ze-lithium, kwelinye icala, azinafuthe lememori kwaye zinokutshajwa nangaliphi na ixesha. Oku kuzenza zikhuseleke kwaye zithembeke ngakumbi ukuzisebenzisa. I-lithium iron phosphate iye yavavanywa ngokukhuselekileyo kwaye ayizukuqhuma nokuba kungqubana ngamandla.
f. Ubuninzi bamandla eebhetri ze-lithium
Iibhetri zeLithium zinamandla amaninzi, okwangoku zifikelela kwi-460-600 Wh/kg, malunga nezihlandlo ezi-6-7 kuneebhetri ze-lead-acid. Oku kuvumela ukugcinwa okungcono kwamandla kwizibane zesitalato zelanga.
g. Izibane zesitalato zelanga zebhetri yeLithium zimelana kakhulu nobushushu.
Izibane zesitalato zelanga zichatshazelwa lilanga yonke imihla, ngoko ke zineemfuneko eziphezulu kwiindawo ezinobushushu. Iibhetri ze-lithium iron phosphate zinomoya ophezulu wokuqhuba ubushushu obuyi-350-500°C kwaye zinokusebenza kwiindawo ezinobushushu obuphakathi kwe--20°C ukuya kwi--60°C.
Ezi zingentla zezinye zeembono ezivela kwiUmenzi wezibane zelanga waseTshayinaTIANXIANG. Ukuba uneengcinga, nceda unxibelelane nathi ukuze ufumane ulwazi oluthe kratya.
