Uhlobo oluvame kakhulu lwebhethri yiseli ye-lithium-ion. Inomthamo omkhulu wamandla futhi inezindleko eziphansi uma kuqhathaniswa ne-watt ngayinye.
Amabhethri e-lithium-ion anikela ngokuphindwe kabili umthamo wokugcina wamaseli e-NiMH, futhi abe nokuminyana kwamandla okuphezulu kunamabhethri e-asidi yomthofu. Aphephile futhi ukuwasebenzisa ngoba awakhiqizi igesi ye-hydrogen lapho eshajwa noma ekhishwa.
Okuwukuphela kwecala lamabhethri e-lithium-ion izindleko zawo eziphezulu uma kuqhathaniswa nezinye izinhlobo zamabhethri.
Amabhethri e-lithiumane-voltage eningi kakhulu kodwa futhi ane-energy density ephansi kakhulu.
I-lead acid inomthamo omkhulu wamandla futhi ivame kakhulu ezimotweni kune-lithium ion ngoba ishibhile ukuyikhiqiza.
Ngithole ukuthi amaphakethe ebhethri ye-lithium ajwayele ukuhlala isikhathi eside kunamabhethri e-asidi eholayo nokuthi amabhethri e-asidi eholayo avame ukuba ngcono ekuqaliseni izinjini ezibandayo kunamaseli e-lithium ion.
Amandla kagesi aphezulu amabhethri e-lithium asho ukuthi angakunikeza amandla engeziwe emoto yakho kagesi noma iloli, kodwa futhi kusho ukuthi uzobe usebenzisa ama-amps (amandla) engeziwe ukuwashaja.
Amabhethri e-Li-ion awuhlobo oludume kakhulu lwamabhethri aphinde ashajwe. Zisetshenziswa kuma-smartphones, ama-laptops nokunye ugesi.
Amabhethri e-lithium anomthamo omkhulu kakhulu wamandla - cishe amahora angama-350 watt ngekhilogremu. Lokho kucishe kuphindwe kabili ukuminyana kwamandla kwamabhethri e-lead acid, okuyizinhlobo zebhethri ezivame ukushajwa.
Nokho, amabhethri e-lithium awahlali isikhathi eside njengezinye izinhlobo ngoba awakwazi ukubamba imali eningi. Lokhu kungenxa yokuthi i-lithium iyinsimbi eguquguqukayo engeke ibambe ukushajwa kwayo uma ivezwe kumazinga okushisa aphezulu noma ingcindezi.
Inkinga enkulu ngamabhethri e-Li-ion ukuthi anomjikelezo wempilo omfushane uma kuqhathaniswa: alahlekelwa amandla ngokuhamba kwesikhathi, okuholela ekunciphiseni kokukhishwayo kanye nokwehluleka ekugcineni uma engashintshwa njalo.
Inhloso enkulu yebhethri ukugcina amandla. Uma ikwazi ukuwagcina amandla engeziwe, izohlala isikhathi eside. Amabhethri akalwa amandla kagesi kanye namandla.
Isilinganiso se-voltage yebhethri yisilinganiso sokuthi anganikeza amandla angakanani. Lapho i-voltage iphezulu, ibhethri linamandla kakhulu. Ibhethri yemoto engu-12-volt ine-voltage ephezulu kunebhethri lemoto engu-6-volt ngoba inamandla amaningi okugcina amandla.
Amandla angenye into ebalulekile ekunqumeni ukuthi idivayisi ingasebenza isikhathi esingakanani ekunikezeni amandla ayo. Amalambu emoto akhanyisa uma inkinobho yesiqalisi icindezelwa; nokho, uma amalambu emoto ephelelwa amandla, ngeke acime aze acishwe mathupha (imvamisa uma injini icishiwe). Ngamanye amazwi, asikho isiqinisekiso sokuthi amalambu akho azohlala ekhanyisiwe ngemva kokucisha injini yemoto yakho ngaphandle uma ukhumbula ukuwavula futhi!
Inani lamandla ebhethri likalwa ngamavolthi.
Ukuminyana kwamandla ukuthi angakanani amandla ibhethri elingawagcina ngeyunithi yevolumu ngayinye noma isisindo.
Amabhethri e-lithium ion anomthamo omkhulu wamandla futhi asetshenziswa kumalaptop, omakhalekhukhwini, ezimotweni zikagesi nakwezinye izimoto zikagesi.
Amabhethri e-lead acid asetshenziswa kakhulu ezimotweni ezisebenzisa amabhethri e-lead-acid ngoba ahlala isikhathi eside kunezinye izinhlobo zamabhethri.
I-voltage ephezulu: Uma iphezulu i-voltage, ibhethri lingakhiqiza ugesi omningi ngesikhathi liwukhipha.
Ibhethri ye-lithium-ion ine-voltage ephezulu kunebhethri le-lead acid nebhethri ye-lithium ion. Ibhethri ye-lead acid ine-voltage ephansi kunebhethri ye-lithium-ion. Ibhethri ye-lithium-ion ine-energy density ephakeme kakhulu kunamanye.
Amabhethri e-lithium awuhlobo olujwayeleke kakhulu lwebhethri ku-elekthronikhi yabathengi, kodwa angagcina inani elilinganiselwe lamandla. Amabhethri e-lead acid ashibhile futhi ahlala isikhathi eside, kodwa awanawo amandla afanayo namabhethri e-lithium-ion.
Inani lamandla ibhethri elingawagcina lincike emandleni alo athile (akalwa ngama-watt-amahora ngekhilogremu) kanye ne-voltage:
Amandla = I-Voltage * Amandla Akhethekile
Uma ufuna ukuthola ibhethri elinamandla kakhulu, bheka amandla alo athile. Uma inombolo iphezulu, amandla engeziwe engawagcina. Nokho, lokhu akusho ukuthi izoba namandla kakhulu kunamanye amabhethri anamandla athize aphansi. Isibonelo, amabhethri e-lead acid anamandla athile aphansi kunalawo e-lithium-ion, kodwa i-voltage yawo iyafana ngakho womabili anamandla acishe abe namandla afanayo kwelinye.
Ibhethri elivame kakhulu ozolithola emotweni ibhethri elineasidi yomthofu. Lezi zinkulu, zisinda futhi zinesisindo esincane samandla.
Ibhethri ye-lithium-ion iwuhlobo oluvame kakhulu lwebhethri elishajekayo elisetshenziswa ezimotweni eziningi zikagesi namuhla. Mancane futhi alula, kodwa futhi anamandla amakhulu okuminyana kunamabhethri e-lead-acid, okuwenza afanelekele kangcono ukunika amandla izinto ezifana namalaptop namaselula.
Abuye abize kakhulu kunamabhethri e-lead-acid, kodwa lokho kuxazululwa ukusebenza kahle kwawo okuphezulu nokuphila isikhathi eside.-ngakho-ke kusene-tradeoff ehilelekile.
Amabhethri ensimbi ye-lithium anomthamo omkhulu wamandla kodwa amandla aphansi-zinhle kakhulu ekugcineni ugesi kodwa azinawo ujusi omningi uma kuziwa ekuwususeni usuka ephuzwini A ukuya endaweni engu-B. Yingakho zisetshenziswa njengemithombo yamandla eyisipele ezikhungweni ezinkulu zezimboni noma izicelo zezempi lapho udinga khona amandla amaningi. emaphaketheni amancane.
liyini ibhethri le-Ion?
Amabhethri e-ion, amabhethri e-alkaline noma amabhethri e-zinc-air, agcina amandla ngokukhulula ukusabela kwe-electrochemical okudala amandla kagesi njengoba ama-electron ehamba ngama-electrode angaphandle ngaphakathi kwekesi yebhethri. Angagcina amandla engeziwe ngevolumu yeyunithi kunezinye izinhlobo zamabhethri ashajwayo.
