Itekhnoloji, izinto eziluncedo, kunye neeNdleko zeebhetri zeLithium-ion

Isebenza njani ibhetri ye-lithium-ion?Zeziphi iingenelo enazo ngaphezu kwebhetri ye-lead-asidi?Ingaba indawo yokugcina ibhetri ye-lithium-ion ihlawula nini?A ibhetri ye-lithium-ion(elifutshane: ibhetri ye-lithiumion okanye ibhetri ye-Li-ion) ligama eliqhelekileyo le-accumulators esekelwe kwiikhompawundi ze-lithium kuzo zonke izigaba ezintathu, kwi-electrode engalunganga, kwi-electrode efanelekileyo kunye nakwi-electrolyte, iseli ye-electrochemical.Ibhetri yeLithium-ion inamandla athile aphezulu xa kuthelekiswa nezinye iintlobo zeebhetri, kodwa zifuna iisekethe zokhuseleko lombane kwizicelo ezininzi, njengoko zisabela kakubi ekukhupheni okunzulu kunye nokugcwala.Iibhetri zelanga ze-Lithium ion zihlawuliswa ngombane kwi-photovoltaic system kwaye ziphinde zikhutshwe kwakhona njengoko zifunwa.Kwangexesha elide, iibhetri ezikhokelayo zazibhekwa njengesisombululo esifanelekileyo sombane welanga kule njongo.Nangona kunjalo, ngokusekwe kwiibhetri ze-lithium-ion zineenzuzo eziqinisekileyo, nangona ukuthengwa kusanxulunyaniswa neendleko ezongezelelweyo, nangona kunjalo, zibuyiselwe ngokusetyenziswa okujoliswe kuko.UbuGcisa boBugcisa kunye neNdlela yokuGcinwa kwamandla eBattery yeLithium-ionIibhetri ze-lithium-ion azihlukanga ngokusisiseko kwiibhetri ze-lead-asidi kwisakhiwo sazo ngokubanzi.I-carrier carrier kuphela iyahluka: Xa ibhetri ihlawuliswa, i-lithium ion "ifuduka" ukusuka kwi-electrode echanekileyo ukuya kwi-electrode engafanelekanga yebhetri kwaye ihlale "igcinwe" apho de ibhetri iphinde ikhutshwe kwakhona.Iiconductors zegraphite ezikumgangatho ophezulu zidla ngokusetyenziswa njengee-electrode.Nangona kunjalo, kukho ukwahluka kunye nabaqhubi bentsimbi okanye abaqhubi be-cobalt.Ngokuxhomekeke kwii-conductors ezisetyenzisiweyo, iibhetri ze-lithium-ion ziya kuba nombane ohlukeneyo.I-electrolyte ngokwayo kufuneka ingabi namanzi kwibhetri ye-lithium-ion ekubeni i-lithium kunye namanzi ibangela ukusabela okunobundlobongela.Ngokuchasene nabaphambili be-asidi ye-lead, iibhetri ze-lithium-ion zanamhlanje (phantse) azikho imiphumo yememori okanye ukuzikhupha, kwaye iibhetri ze-lithium-ion zigcina amandla abo apheleleyo ixesha elide.Iibhetri zokugcina amandla e-lithium-ion zihlala zibandakanya izinto zekhemikhali i-manganese, i-nickel kunye ne-cobalt.I-Cobalt (igama lekhemikhali: i-cobalt) yinto enqabileyo kwaye ngoko yenza ukuveliswa kweebhetri zokugcina i-Li kubize kakhulu.Ukongeza, i-cobalt iyingozi kwindalo.Ngoko ke, kukho iinzame ezininzi zophando zokuvelisa izinto ze-cathode ze-lithium-ion iibhetri eziphezulu ze-voltage ngaphandle kwe-cobalt.Izinto eziluncedo kwiibhetri zeLithium-ion ngaphezu kweebhetri zeLead-acid◎Ukusetyenziswa kweebhetri ze-lithium-ion zanamhlanje kuzisa inani leenzuzo ukuba iibhetri ezilula ze-lead-acid azikwazi ukuhambisa.◎Enye into, banobomi benkonzo obude kakhulu kuneebhetri ze-lead-asidi.Ibhetri ye-lithium-ion iyakwazi ukugcina amandla elanga ixesha eliphantse libe yi-20 iminyaka.◎Inani lemijikelo yokutshaja kunye nobunzulu bokukhutshwa kwakhona bukhulu ngokuphindwe kaninzi kuneebhetri zelothe.◎Ngenxa yezixhobo ezahlukeneyo ezisetyenziswa kwimveliso, iibhetri ze-lithium-ion nazo zikhaphukhaphu kakhulu kuneebhetri ezikhokelayo kwaye zixinene ngakumbi.Ngoko ke, bathatha indawo encinci ngexesha lofakelo.◎Iibhetri ze-lithium-ion nazo zineendawo zokugcina ezingcono ngokuzikhupha.◎Ukongeza, umntu makangalibali inkalo yokusingqongileyo: Ngenxa yokuba iibhetri ezikhokelayo azinabungozi ngokukodwa kokusingqongileyo kwimveliso yazo ngenxa yokhokelo olusetyenziswayo.Imizobo engundoqo yobuGcisa yeebhetri zeLithium-ionKwelinye icala, kufuneka kukhankanywe kwakhona ukuba, ngenxa yexesha elide lokusetyenziswa kweebhetri zelothe, kukho izifundo ezinentsingiselo yexesha elide kuneebhetri ze-lithium-ion zintsha kakhulu, ukuze ukusetyenziswa kwazo kunye neendleko ezinxulumene nazo. ingabalwa ngcono nangokuthembekileyo.Ukongeza, inkqubo yokhuseleko yeebhetri ezikhokelayo zanamhlanje iyinxalenye engcono ngakumbi kuneebhetri ze-lithium-ion.Ngokomgaqo, inkxalabo malunga neziphene ezinobungozi kwiiseli ze-li ion nazo azinasiseko: Umzekelo, i-dendrites, oko kukuthi i-lithium deposits, inokwakheka kwi-anode.Amathuba okuba ezi zibangele iisekethe ezimfutshane, kwaye ke ekugqibeleni zibangele ukubaleka kwe-thermal (i-reaction exothermic enesizukulwana esinamandla, esizinyusayo sobushushu), inikwa ngokukodwa kwiiseli ze-lithium eziqulethe amacandelo eseli asezantsi.Kwimeko embi kakhulu, ukusasazwa kwesi siphoso kwiiseli ezingabamelwane kunokukhokelela ekuphenduleni kwekhonkco kunye nomlilo kwibhetri.Nangona kunjalo, njengoko abathengi besanda besebenzisa iibhetri ze-lithium-ion njengeebhetri zelanga, iziphumo zokufunda zabavelisi kunye nomthamo omkhulu wemveliso zikhokelela ekuphuculweni ngakumbi kobugcisa bokugcinwa kunye nokhuseleko oluphezulu lokusebenza kweebhetri ze-lithium-ion kunye nokunciphisa iindleko. .Ubume bangoku bophuhliso lobugcisa beebhetri ze-Li-ion sinokushwankathelwa kula manani alandelayo obugcisa:

Umthamo wokuGcina kunye neeNdleko zeLithium-ion iibhetri zeSolarIindleko zebhetri yelanga ye-lithium-ion iphezulu ngokubanzi kunebhetri ye-lead-acid.Umzekelo, iibhetri ezikhokelayo ezinomthamo we5 kWhngoku ixabisa i-avareji ye-800 yeedola nge-kilowatt ngeyure yomthamo oqhelekileyo.Iinkqubo zokuthelekisa i-lithium, kwelinye icala, zibiza i-1,700 yeedola ngeyure ye-kilowatt.Nangona kunjalo, ukusasazwa phakathi kwezona nkqubo zinexabiso eliphantsi kunye nezona zibiza kakhulu kuphezulu kakhulu kuneenkqubo zelothe.Umzekelo, iibhetri ze-lithium ezine-5 kWh nazo ziyafumaneka nge-1,200 yeedola nge-kWh nganye.Nangona iindleko zokuthenga ngokubanzi, nangona kunjalo, iindleko zenkqubo yebhetri yelanga ye-lithium-ion kwiyure nganye egciniweyo ye-kilowatt ithandeka ngakumbi kubalwa ubomi benkonzo yonke, kuba iibhetri ze-lithium-ion zinika amandla ixesha elide kuneebhetri ze-asidi ezikhokelayo. ukutshintshwa emva kwexesha elithile.Ngoko ke, xa kuthengwa inkqubo yokugcina ibhetri yokuhlala, umntu makangoyiki ngeendleko eziphezulu zokuthenga, kodwa kufuneka ahlale ehambelana nokusebenza kwezoqoqosho kwebhetri ye-lithium-ion kubomi benkonzo yonke kunye nenani leeyure ze-kilowatt ezigciniweyo.Ezi fomyula zilandelayo zingasetyenziselwa ukubala onke amanani aphambili enkqubo yokugcina ibhetri ye-lithium-ion kwiinkqubo zePV:1) Umthamo wegama * imijikelo yentlawulo = Umthamo wogcino lwethiyori.2) Umthamo wogcino lwethiyori * Ukusebenza kakuhle * Ubunzulu bokukhutshwa = Umthamo wokugcina osetyenziswayo3) Ixabiso lokuthenga / Umthamo wokugcina onokusetyenziswa = Iindleko nge-kWh egciniweyo

I-BSLBATT: Umvelisi weebhetri zeSolar Lithium-ionKukho ngoku abaninzi abavelisi kunye nababoneleli beebhetri ze-lithium-ion.I-BSLBATT iibhetri zelanga ze-lithium-ionsebenzisa iiseli ze-A-grade LiFePo4 ezivela kwi-BYD, i-Nintec, kunye ne-CATL, zidibanise, kwaye zibonelele ngenkqubo yokulawula intlawulo (inkqubo yokulawula ibhetri) eguqulelwe kwisitoreji samandla e-photovoltaic ukuze kuqinisekiswe ukusebenza okufanelekileyo kunye nokungenazinkathazo kwiseli nganye yokugcina njengoko kunye nenkqubo yonke.
