Isingeniso:
Amabhethri angahlukaniswa kabanzi ngezigaba ezintathu: amabhethri amakhemikhali, amabhethri omzimba namabhethri ezinto eziphilayo. Amabhethri amakhemikhali asetshenziswa kakhulu ezimotweni zikagesi.
Ibhethri lamakhemikhali: Ibhethri lamakhemikhali yithuluzi eliguqula amandla amakhemikhali abe amandla kagesi ngokuphendula kwamakhemikhali. Siqukethe ama-electrodes amahle futhi alungile nama-electrolyte.
Ibhethri Lokomzimba: Ibhethri elingokomzimba liguqula amandla omzimba (njengamandla elanga namandla emishini) emandleni kagesi ngezinguquko zomzimba.
Ukuhlukaniswa kwebhethri lamakhemikhali: kusuka ekubukeni okuhlelekile, kungahlukaniswa ngezigaba ezimbili: amabhethri wesitoreji (kufaka amabhethri aphambili namabhethri wesibili) namaseli kaphethiloli. Amabhethri abuyisisekelo: angasetshenziswa kuphela kanye, izinto ezisebenzayo azinakuphikwa, ukuzikhipha zincane, ukumelana kwangaphakathi kukhulu, futhi umthamo othize wevolumu kanye namandla athile athile aphezulu.
Amabhethri wesibili: angakhokhiswa futhi akhishwe kaninginingi, izinto ezisebenzayo ziguqulwa, futhi zisetshenziswa kabanzi kumadivayisi ahlukahlukene wokushaja. Iningi lamamodeli emakethe njengamanje lisebenzisa amabhethri avuselelwa okwesibili ukushayela imoto. Amabhethri wesibili ahlukaniswe amabhethri e-lead-acid, amabhethri e-nickel-cadmium, amabhethri we-nithisi-metal hydrid kanye namabhethri e-lithium ngokuya ngezinto ezihlukile ze-elektrodi. Njengamanje, izinkampani zezimoto ezimakethe zisebenzisa ikakhulukaziamabhethri e-lithium, kanye namabhethri ambalwa e-nickel-metal hydride.
Ukuchazwa kwebhethri le-lithium
Ibhethri le-lithiumIbhethri elisebenzisa i-lithium Metal noma i-Lithium Alloy njenge-elektrode ene-elektrode elilungile noma elingesihle nesixazululo esingalungile se-electrolyte.
Ukushaja kanye nenqubo yokukhipha i-Lithium yebhethri kuncike kakhulu ekuhambeni kwama-lithium ions (li +) phakathi kwama-electrodes amahle nengalungile. Lapho ishaja, i-lithium ion ine-deintercalcalted kusuka ku-electrode enhle futhi ifakwe ku-electrode engemihle nge-electrode, kanti i-electrode engemihle isesimweni se-lithium-rich esimweni esicebile se-lithium; okuphambene nalokho kuyiqiniso lapho kukhishwa.
Umgomo we-Electrochemical we-Lithium-Ion Battery
Ifomula yokuphendula i-elektrodi enhle: I-Lico2 → uLi1-XCOO2 + XLI + + + XE-
Ifomula yokuphendula nge-electrode ye-electrode: C + Xli + + xe- x- clix
Amabhethri e-Lithium-Ion anobunzima obuphakeme wamandla, impilo ende nesilinganiso esiphansi sokuzikhulula, futhi asetshenziswa kabanzi kumaselula, ama-laptops nezimoto zikagesi.
Izinkambu zohlelo lokusebenza zeamabhethri e-lithiumzihlukaniswe ikakhulu amandla namandla. Izinkambu zamandla ze-Lithium-Ion zebhethri zebhethri zifaka izimoto zikagesi, amathuluzi wamandla, njll; Izinkambu ezingezona amandla zifaka ama-elekthronikhi abathengi nezinkundla zokugcina amandla, njll.
Ukwakheka kanye nokuhlukaniswa kwamabhethri e-lithium
Amabhethri e-Lithium ikakhulukazi akhiwa ngezingxenye ezine: izinto ezilungile ze-elektrode, izinto ezingezinhle ze-elektrodi, ama-electrode kanye nabahlukanisi bebhethri. Izinto ezingezinhle ze-elektrode zithinta kakhulu ukusebenza kahle kokuqala kanye nomjikelezo wokusebenza kwamabhethri we-lithium-ion. Ama-elektrodi e-lithium amanga amanga ahlukaniswe izigaba ezimbili: izinto zekhabhoni nezinto ezingezona zekhabhoni. Uhlelo lokusebenza olusemakethe kunazo zonke ezisetshenziswayo yi-graphite electrode ezintweni ezingezinhle ze-electrode phakathi kwezinto zekhabhoni, phakathi kwalona i-graphiolial graphiolity kanye graphite yemvelo inezicelo ezinkulu zezimboni. Ama-elektrodi amabi asuselwa ku-silicon agxile ocwaningweni ngabakhiqizi abakhulu bama-elektrode ababi futhi bangenye yezinto ezintsha ze-elektrodi okungenzeka ukuthi zisetshenziswe ngezinga elikhulu ngokuzayo.
Amabhethri e-lithiumzihlukaniswa zibe amabhethri e-lithium cobalt oxide, amabhethri we-lithium iron phosphate, amabhethri endalo, njll ngokuya ngezinto ezinhle ze-elektrodi;
Ngokuya ngefomu lomkhiqizo, ahlukaniswe amabhethri ayisikwele, amabhethri we-cylindrical namabhethri epakishi elithambile;
Ngokwezimo zohlelo lokusebenza, zingahlukaniswa zaba ama-elekthronikhi abathengi, ukugcinwa kwamandla namabhethri anamandla. Phakathi kwazo, amabhethri e-lithithium abathengi asetshenziswa ikakhulukazi kwimikhiqizo ye-3C; Amabhethri wokugcina amandla asetshenziswa ikakhulukazi kwisitoreji samandla ezindlini futhi asatshalaliswa uhlelo oluzimele oluzimele lwamandla Amabhethri anamandla asetshenziswa ikakhulukazi ezimotweni ezahlukahlukene zikagesi, amathuluzi kagesi nezimoto ezintsha zamandla.
