Izibane zesitalato ezisebenzisa amandla elanga zibe yinxalenye ebalulekileyo yeziseko zophuhliso zasezidolophini zanamhlanje, zibonelela ngesisombululo sokukhanyisa esinobuhlobo nokusingqongileyo nesingabizi kakhulu. Ezi zibane zixhomekeke kwiintlobo ngeentlobo zeebhetri ukugcina amandla abanjwa ziiphaneli zelanga emini.
1. Izibane zesitalato zelanga zihlala zisebenzisa iibhetri ze-lithium iron phosphate:
Yintoni ibhetri ye-lithium iron phosphate?
Ibhetri ye-lithium iron phosphate luhlobo lwebhetri ye-lithium-ion esebenzisa i-lithium iron phosphate (LiFePO4) njengezinto ze-cathode kunye ne-carbon njengezinto ze-anode. I-voltage eqhelekileyo yeseli enye yi-3.2V, kwaye i-voltage yokunqunyulwa kokutshaja iphakathi kwe-3.6V kunye ne-3.65V. Ngexesha lokutshaja, ii-lithium ion ziyaphuma kwi-lithium iron phosphate zize zihambe nge-electrolyte ziye kwi-anode, zingene kwi-carbon material. Kwangaxeshanye, ii-electron zikhutshwa kwi-cathode zize zihambe nge-external circuit ziye kwi-anode ukuze kugcinwe ibhalansi ye-chemical reaction. Ngexesha lokukhupha, ii-lithium ion zihamba ukusuka kwi-anode ukuya kwi-cathode nge-electrolyte, ngelixa ii-electron zihamba ukusuka kwi-anode ukuya kwi-cathode nge-external circuit, zinika amandla kwihlabathi langaphandle.
Ibhetri ye-lithium iron phosphate idibanisa iingenelo ezininzi: uxinano olukhulu lwamandla, ubungakanani obuncinci, ukutshaja ngokukhawuleza, ukuqina, kunye nozinzo oluhle. Nangona kunjalo, ikwayeyona ibiza kakhulu phakathi kwazo zonke iibhetri. Ihlala ixhasa iitshaja zomjikelo onzulu we-1500-2000 kwaye ingahlala iminyaka eyi-8-10 phantsi kokusetyenziswa okuqhelekileyo. Isebenza kuluhlu olubanzi lobushushu ukusuka kwi--40°C ukuya kwi-70°C.
2. Iibhetri zeColloidal ezisetyenziswa kakhulu kwizibane zesitalato zelanga:
Yintoni ibhetri ye-colloidal?
Ibhetri ye-colloidal luhlobo lwebhetri ye-lead-acid apho i-gelling agent yongezwa kwi-sulfuric acid, iguqula i-electrolyte ibe yimeko efana ne-gel. Ezi bhetri, kunye ne-gel electrolyte yazo, zibizwa ngokuba ziibhetri ze-colloidal. Ngokungafaniyo neebhetri ze-lead-acid eziqhelekileyo, iibhetri ze-colloidal ziphucula iipropati ze-electrochemical zesakhiwo sesiseko se-electrolyte.
Iibhetri zeColloidal azinazo izinto ezigcinwayo, zisoyisa iingxaki zokugcinwa rhoqo ezinxulumene neebhetri ze-lead-acid. Ulwakhiwo lwazo lwangaphakathi luthatha indawo ye-electrolyte ye-sulfuric acid engamanzi ngenguqulelo ye-gelled, nto leyo ephucula kakhulu ukugcinwa kwamandla, amandla okukhupha, ukusebenza kokhuseleko, kunye nobomi, ngamanye amaxesha zide ziphumelele ngaphezu kweebhetri ze-lithium-ion ze-ternary ngokwexabiso. Iibhetri zeColloidal zinokusebenza ngaphakathi koluhlu lobushushu ukusuka kwi--40°C ukuya kwi-65°C, nto leyo ezenze zilungele ukusetyenziswa kwiindawo ezibandayo. Zikwamelana nokutshaqeka kwaye zingasetyenziswa ngokukhuselekileyo phantsi kweemeko ezahlukeneyo ezinzima. Ubomi bazo benkonzo buphindwe kabini okanye ngaphezulu xa kuthelekiswa neebhetri eziqhelekileyo ze-lead-acid.
3. Iibhetri ze-NMC lithium-ion ezisetyenziswa kakhulu kwizibane zesitalato zelanga:
Iibhetri ze-NMC lithium-ion zibonelela ngeenzuzo ezininzi: amandla athile aphezulu, ubungakanani obuncinci, kunye nokutshaja ngokukhawuleza. Zihlala zixhasa iitshaja zomjikelo onzulu ezingama-500-800, kwaye ubomi bazo bufana neebhetri ze-colloidal. Ububanzi bobushushu bazo bokusebenza buyi--15°C ukuya kwi-45°C. Nangona kunjalo, iibhetri ze-NMC lithium-ion nazo zineengxaki, kubandakanya ukuzinza okuncinci kwangaphakathi. Ukuba ziveliswa ngabavelisi abangafanelekiyo, kukho umngcipheko wokuqhuma ngexesha lokutshaja kakhulu okanye kwiindawo ezinobushushu obuphezulu.
4. Iibhetri ze-lead-acid ezisetyenziswa kakhulu kwizibane zesitalato zelanga:
Iibhetri ze-lead-acid zinee-electrodes ezenziwe yi-lead kunye ne-lead oxide, kunye ne-electrolyte eyenziwe ngesisombululo se-sulfuric acid. Iingenelo eziphambili zeebhetri ze-lead-acid yi-voltage yazo ezinzileyo kunye nexabiso eliphantsi. Nangona kunjalo, zinamandla athile aphantsi, nto leyo ebangela ukuba zibe nomthamo omkhulu xa kuthelekiswa nezinye iibhetri. Ubomi bazo bufutshane, ngokubanzi zixhasa iitshaja zomjikelo onzulu ezingama-300-500, kwaye zifuna ukulungiswa rhoqo. Nangona ezi ngxaki zingekho, iibhetri ze-lead-acid zisasetyenziswa kakhulu kushishino lwezibane zesitalato zelanga ngenxa yenzuzo yazo yeendleko.
Ukukhethwa kwebhetri yezibane zesitalato zelanga kuxhomekeke kwizinto ezifana nokusebenza kakuhle kwamandla, ubomi, iimfuno zokugcinwa, kunye neendleko. Uhlobo ngalunye lwebhetri luneengenelo zalo ezikhethekileyo, luhambelana neemfuno neemeko ezahlukeneyo, luqinisekisa ukuba izibane zesitalato zelanga zihlala zisisombululo sokukhanya esithembekileyo nesizinzileyo.
