Olona hlobo luqhelekileyo lwebhetri yiseli ye-lithium-ion.Inoxinano olukhulu lwamandla kwaye inexabiso eliphantsi ngokwewatt nganye.
Iibhetri ze-lithium-ion zinika ngokuphindwe kabini amandla okugcina iiseli ze-NiMH, kwaye zinezinga eliphezulu lokuxinana kwamandla kuneebhetri ze-asidi ekhokelayo.Zikwakhuseleke ngakumbi ukuzisebenzisa kuba azivelisi rhasi yehydrogen xa zitshaja okanye zikhupha.
Ukuphela kweebhetri ze-lithium-ion ziindleko zabo eziphezulu xa kuthelekiswa nezinye iintlobo zeebhetri.
Iibhetri zeLithiumzinamandla ombane amaninzi kodwa zikwanazo noxinano lwamandla asezantsi.
Iasidi ye-lead inoxinano lwamandla aphezulu kwaye ixhaphake kakhulu kwizithuthi kune-lithium ion kuba zixabiso eliphantsi ukwenza.
Ndifumanise ukuba iibhetri ze-lithium zebhetri zihlala ixesha elide kuneebhetri ze-asidi ezikhokelayo kwaye iibhetri ze-asidi ezikhokelayo zivame ukuba ngcono ekuqaliseni iinjini ezibandayo kuneeseli ze-lithium ion.
Amandla ombane aphezulu eebhetri ze-lithium athetha ukuba anokubonelela ngamandla kwimoto yakho yombane okanye kwilori, kodwa kukwathetha ukuba uya kusebenzisa ii-amps ezininzi (amandla) ukuzihlawulisa.
Iibhetri ze-Li-ion lolona hlobo ludumileyo lweebhetri ezinokutshajwa kwakhona.Zisetyenziswa kwii-smartphones, iilaptops kunye nezinye izinto zombane.
Iibhetri zeLithium zinoxinzelelo olukhulu kakhulu lwamandla - malunga neeyure ezingama-350 watt ngekhilogram.Oko kumalunga nokuphinda-phindeka kwamandla okuxinana kweebhetri zeasidi yelothe, ezizezona ntlobo zebhetri ezinokutshajwa kwakhona.
Nangona kunjalo, iibhetri ze-lithium azihlali ixesha elide njengezinye iintlobo kuba azikwazi ukubamba intlawulo eninzi.Oku kungenxa yokuba i-lithium yintsimbi eguquguqukayo engayi kubamba intlawulo yayo ukuba ibonakaliswe kumaqondo aphezulu okanye uxinzelelo.
Eyona ngxaki inkulu ngeebhetri ze-Li-ion kukuba zinomjikelo wobomi obufutshane: zilahlekelwa ngumthamo ekuhambeni kwexesha, okukhokelela ekuncitshisweni kwemveliso kunye nokusilela ekugqibeleni ukuba azitshintshwa rhoqo.
Eyona njongo yebhetri kukugcina amandla.Xa ikwazi ukugcina amandla amaninzi, iya kuhlala ixesha elide.Iibhetri zilinganiswe ngamandla ombane kunye nomthamo wazo.
Umlinganiselo wombane webhetri ngumlinganiselo wokuba angakanani amandla anokubonelela ngawo.Ukuphakama kwamandla ombane, ibhetri inamandla ngakumbi.Ibhetri yemoto ye-12-volt ine-voltage ephezulu kune-6-volt ibhetri yemoto kuba inamandla okugcina amandla.
Umthamo yenye into ebalulekileyo ekumiseleni ukuba isixhobo sinokusebenza ixesha elingakanani kunikezelo lwaso lombane.Izibane zemoto zilayita xa iqhosha lokuqalisa licofa;nangona kunjalo, ukuba izibane zemoto zisebenza phantsi kwamandla, aziyi kucima de zicinywe ngesandla (ngokuqhelekileyo injini icinyiwe).Ngamanye amazwi, akukho siqinisekiso sokuba izibane zakho ziya kuhlala zikhanya emva kokucima i-injini yemoto yakho ngaphandle kokuba uyakhumbula ukuzilayita kwakhona!
Isixa samandla ebhetri silinganiswa ngeevolthi.
Ubuninzi bamandla bubungakanani bamandla anokugcinwa yibhetri ngeyunithi yevolumu okanye ubunzima.
Iibhetri ze-ion ze-lithium zinamandla aphezulu kwaye zisetyenziswa kwii-laptops, iiselfowuni, izithuthi zombane kunye nezinye iimoto zombane.
Iibhetri ze-lead zezona ziqhele ukusetyenziswa kwiimoto ezisebenzisa iibhetri ze-lead-asidi kuba zihlala ixesha elide kunezinye iintlobo zeebhetri.
I-voltage ephezulu: Ukuphakama kombane, ngakumbi umbane onokuthi uvelise ibhetri ngexesha lokukhutshwa.
Ibhetri ye-lithium-ion ine-voltage ephezulu kune-lead ibhetri ye-asidi kunye nebhetri ye-lithium ion.Ibhetri ye-asidi ekhokelayo ine-voltage ephantsi kunebhetri ye-lithium-ion.Ibhetri ye-lithium-ion inobuninzi bamandla obuphezulu kakhulu kunabanye.
Iibhetri zeLithium lolona hlobo luxhaphakileyo lwebhetri kubathengi be-elektroniki, kodwa banokugcina isixa esilinganiselweyo samandla.Iibhetri ze-lead ze-asidi zinexabiso eliphantsi kwaye zihlala ixesha elide, kodwa azinawo amandla afanayo njengebhetri ye-lithium-ion.
Ubungakanani bamandla enokugcinwa yibhetri buxhomekeke kumandla ayo athile (alinganiselwa kwiiwatt-yure ngekhilogram) kunye nombane:
Amandla = Umbane * Amandla athile
Ukuba ufuna ukufumana ibhetri enamandla kakhulu, jonga amandla ayo athile.Okukhona liphezulu inani, kokukhona likwazi ukugcina amandla amaninzi.Nangona kunjalo, oku akuthethi ukuba iya kuba namandla ngakumbi kunezinye iibhetri ezinamandla athile asezantsi.Umzekelo, iibhetri ze-lead ze-asidi zinamandla athile angaphantsi kune-lithium-ion, kodwa i-voltage yazo iyafana ngoko zombini zinamandla alinganayo omnye komnye.
Elona bhetri lixhaphakileyo onokulifumana emotweni yibhetri eneasidi ekhokelayo.Ezi zinkulu, zinzima kwaye zine-low density yamandla.
Ibhetri ye-lithium-ion yolona hlobo luqhelekileyo lwebhetri ehlaziywayo esetyenziswa kwiimoto ezininzi zombane namhlanje.Zincinci kwaye zikhaphukhaphu, kodwa zikwanamandla oxinaniso aphezulu kuneebhetri ze-lead-asidi, nto leyo ezenza zikufanelekele ngakumbi ukunika amandla izinto ezifana neelaptops kunye neeselfowuni.
Zikwabiza kakhulu kuneebhetri ze-lead-asidi, kodwa oko kulungiswa kukusebenza kwazo okuphezulu kunye nobomi obude.-ngoko kusekho urhwebo olubandakanyekayo.
Iibhetri zesinyithi zeLithium zinoxinaniso lwamandla aphezulu kodwa uxinano lwamandla aphantsi-zilungile ukugcina umbane kodwa zingenayo incindi eninzi xa kuziwa ekuyisuseni ukusuka kwindawo A ukuya kwindawo B. Kungenxa yoko le nto zisetyenziswa njengemithombo yogcino lwamandla kumaziko amakhulu amashishini okanye izicelo zomkhosi apho ufuna amandla amaninzi. kwiipakethe ezincinci.
yintoni ibhetri yeIon?
Iibhetri ze-Ion, iibhetri ze-alkaline okanye iibhetri zomoya we-zinc, zigcina amandla ngokukhupha i-electrochemical reaction eyenza umbane njengoko ii-electron zihamba ngee-electrode zangaphandle ngaphakathi kwebhetri.Bangakwazi ukugcina amandla amaninzi kwiyunithi yeyunithi kunezinye iintlobo zeebhetri ezitshajekayo.
