Isingeniso:
Amabhethri angahlukaniswa kabanzi ngezigaba ezintathu: amabhethri amakhemikhali, amabhethri angokoqobo kanye namabhethri ezinto eziphilayo. Amabhethri amakhemikhali yiwona asetshenziswa kakhulu ezimotweni zikagesi.
Ibhethri lamakhemikhali: Ibhethri lamakhemikhali liyithuluzi eliguqula amandla amakhemikhali abe amandla kagesi ngokusebenzisa ukusabela kwamakhemikhali. Liqukethe ama-electrode nama-electrolyte amahle nangalungile.
Ibhethri elingokoqobo: Ibhethri elingokoqobo liguqula amandla angokoqobo (njengamandla elanga kanye namandla omshini) abe amandla kagesi ngokusebenzisa izinguquko ezingokoqobo.
Ukuhlukaniswa kwamabhethri amakhemikhali: Ngokombono wesakhiwo, kungahlukaniswa ngezigaba ezimbili: amabhethri okugcina (kufaka phakathi amabhethri ayinhloko namabhethri esibili) kanye namaseli kaphethiloli. Amabhethri ayinhloko: angasetshenziswa kanye kuphela, izinto ezisebenzayo azikwazi ukuguqulwa, ukuzikhipha kuncane, ukumelana kwangaphakathi kukhulu, kanti umthamo othize wesisindo kanye nomthamo othize kuphezulu.
Amabhethri esibili: angashajwa futhi akhishwe ngokuphindaphindiwe, izinto ezisebenzayo ziyaguqulwa, futhi zisetshenziswa kabanzi kumadivayisi ahlukahlukene okushaja. Iningi lamamodeli emakethe okwamanje lisebenzisa amabhethri esibili angashajwa kabusha ukushayela imoto. Amabhethri esibili ahlukaniswe ngamabhethri e-lead-acid, amabhethri e-nickel-cadmium, amabhethri e-nickel-metal hydride kanye namabhethri e-lithium ngokwezinto ezahlukene ze-electrode ezinhle. Njengamanje, izinkampani zezimoto emakethe zisebenzisa kakhulu amabhethri e-lithium, kanti ezimbalwa zisebenzisa amabhethri e-nickel-metal hydride.
Incazelo yebhethri le-lithium
Ibhethri le-lithium yibhethri elisebenzisa insimbi ye-lithium noma i-lithium alloy njengezinto ze-electrode ezinhle noma ezimbi kanye nesisombululo se-electrolyte esingemanzi.
Inqubo yokushaja nokukhipha ibhethri le-lithium incike kakhulu ekuhambeni kwama-ion e-lithium (Li+) phakathi kwama-electrode amahle nangalungile. Lapho kushajwa, ama-ion e-lithium ayasuswa ku-electrode enhle bese efakwa ku-electrode engalungile nge-electrolyte, bese i-electrode engalungile isesimweni esicebile nge-lithium; okuphambene nalokho kuyiqiniso lapho kushajwa.
Isimiso se-electrochemical sebhethri le-lithium-ion
Ifomula yokusabela kwe-electrode enhle: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Ifomula yokusabela kwe-electrode engalungile: C + xLi + + xe- → CLix
Amabhethri e-lithium-ion anamandla amaningi, ahlala isikhathi eside futhi aphansi ekuzikhipheni, futhi asetshenziswa kabanzi kumaselula, kuma-laptop nasezimotweni zikagesi.
Izinkambu zokusetshenziswa kwamabhethri e-lithium-ion zihlukaniswe kakhulu zibe amandla kanye nezingewona amandla. Izinkambu zamandla zezinhlelo zokusebenza zamabhethri e-lithium-ion zifaka phakathi izimoto zikagesi, amathuluzi kagesi, njll.; izinkambu ezingewona amandla zifaka phakathi ama-electronics abathengi kanye nezinkambu zokugcina amandla, njll.
Ukwakheka kanye nokuhlukaniswa kwamabhethri e-lithium
Amabhethri e-lithium-ion akhiwe kakhulu yizingxenye ezine: izinto ze-electrode ezinhle, izinto ze-electrode ezimbi, ama-electrolyte kanye nabahlukanisi bebhethri. Izinto ze-electrode ezimbi zithinta kakhulu ukusebenza kahle kokuqala kanye nokusebenza komjikelezo wamabhethri e-lithium-ion. Ama-electrode angalungile ebhethri le-lithium ahlukaniswe kakhulu ngezigaba ezimbili: izinto ze-carbon kanye nezinto ezingezona ze-carbon. Ukusetshenziswa okugxile kakhulu emakethe yizinto ze-electrode ezimbi ze-graphite phakathi kwezinto ze-carbon, phakathi kwazo i-graphite yokwenziwa kanye ne-graphite yemvelo enezinhlelo zokusebenza ezinkulu zezimboni. Ama-electrode angalungile asekelwe ku-silicon agxile ocwaningweni ngabakhiqizi abakhulu be-electrode ezimbi futhi angenye yezinto ezintsha ze-electrode ezimbi okungenzeka ukuthi zisetshenziswe ngezinga elikhulu esikhathini esizayo.
Amabhethri e-lithium-ion ahlukaniswa ngamabhethri e-lithium cobalt oxide, amabhethri e-lithium iron phosphate, amabhethri e-ternary, njll. ngokuya ngezinto ze-electrode ezinhle;
Ngokwefomu lomkhiqizo, zihlukaniswe ngamabhethri ayisikwele, amabhethri ayisilinda kanye namabhethri athambile;
Ngokwezimo zohlelo lokusebenza, zingahlukaniswa ngama-electronics abathengi, isitoreji samandla kanye namabhethri kagesi. Phakathi kwazo, amabhethri e-lithium abathengi asetshenziswa kakhulu emikhiqizweni ye-3C; amabhethri okugcina amandla asetshenziswa kakhulu ekugcinweni kwamandla kwasekhaya kanye nesitoreji samandla esizimele esisakazwayo njengogesi welanga kanye nokukhiqizwa kwamandla omoya; amabhethri kagesi asetshenziswa kakhulu ezimotweni zikagesi ezahlukahlukene, amathuluzi kagesi kanye nezimoto ezintsha zamandla.
