Isingeniso:
Amabhethri angahlukaniswa ngobubanzi abe yizigaba ezintathu: amabhethri amakhemikhali, amabhethri aphathekayo namabhethri ebhayoloji. Amabhethri amakhemikhali yiwona asetshenziswa kakhulu ezimotweni zikagesi.
Ibhethri lekhemikhali: Ibhethri lekhemikhali iyisisetshenziswa esiguqula amandla amakhemikhali abe amandla kagesi ngokusabela kwamakhemikhali. Iqukethe ama-electrode amahle kanye nama-electrolyte.
Ibhethri eliphathekayo: Ibhethri eliphathekayo liguqula amandla aphathekayo (njengamandla elanga namandla asetshenziswayo) libe amandla kagesi ngoshintsho olubonakalayo.
Ukuhlukaniswa kwebhethri yekhemikhali: Ngokombono wesakhiwo, ingahlukaniswa ngezigaba ezimbili: amabhethri okugcina (okuhlanganisa amabhethri ayinhloko namabhethri esibili) namaseli kaphethiloli. Amabhethri ayisisekelo: angasetshenziswa kanye kuphela, izinto ezisebenzayo azibuyiseleki emuva, ukuzikhipha kuncane, ukumelana kwangaphakathi kukhulu, futhi umthamo othize wenqwaba kanye nomthamo othize wevolumu uphezulu.
Amabhethri esibili: angashajwa futhi ashajwe ngokuphindaphindiwe, okokusebenza okusebenzayo kuyabuyiseleka emuva, futhi asetshenziswa kakhulu kumadivayisi ahlukahlukene wokushaja. Iningi lamamodeli emakethe njengamanje asebenzisa amabhethri esibili aphinde ashajwe ukushayela imoto. Amabhethri esibili ahlukaniswe abe amabhethri e-lead-acid, amabhethri e-nickel-cadmium, amabhethri e-nickel-metal hydride kanye namabhethri e-lithium ngokuya ngezinto ezihlukile ze-electrode eziqondile. Njengamanje, izinkampani zezimoto emakethe zisebenzisa kakhuluamabhethri e-lithium, futhi abambalwa basebenzisa amabhethri e-nickel-metal hydride.
Incazelo yebhethri ye-lithium
Ibhethri ye-lithiumibhethri elisebenzisa i-lithium metal noma i-lithium alloy njengento ephozithivu noma engemihle ye-electrode kanye nesisombululo se-electrolyte esingenamanzi.
Inqubo yokushaja nokukhipha ibhethri ye-lithium incike kakhulu ekuhambeni kwe-lithium ion (Li+) phakathi kwama-electrode aqondile noma angalungile. Lapho ishaja, i-lithium ion ihlukaniswa ne-electrode enhle futhi ishumekwe ku-electrode engalungile nge-electrolyte, futhi i-electrode engalungile isesimweni esicebile i-lithium; okuphambene kuyiqiniso lapho ukhipha.
Isimiso se-Electrochemical sebhethri ye-lithium-ion
Ifomula yokusabela kahle kwe-electrode: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Ifomula yokusabela kwe-electrode engemihle: C + xLi+ + xe- → CLix
Amabhethri e-lithium-ion anomthamo omkhulu wamandla, impilo ende kanye nezinga eliphansi lokuzikhipha, futhi asetshenziswa kakhulu kumaselula, amalaptop nezimoto zikagesi.
Izinkambu zesicelo zeamabhethri e-lithiumikakhulukazi ihlukaniswe amandla kanye nokungewona amandla. Izinkambu zamandla zezicelo zebhethri ze-lithium-ion zihlanganisa izimoto zikagesi, amathuluzi kagesi, njll.; izinkambu ezingezona amandla zihlanganisa ama-electronics abathengi kanye nezinkambu zokugcina amandla, njll.
Ukwakheka nokuhlukaniswa kwamabhethri e-lithium
Amabhethri e-lithium akhiwa ngokuyinhloko izingxenye ezine: izinto ezisetshenziswayo zikagesi ezinhle, izinto ezingezinhle ze-electrode, ama-electrolyte nezihlukanisi zebhethri. Izinto ze-electrode ezingezinhle zithinta ikakhulukazi ukusebenza kahle kokuqala kanye nokusebenza komjikelezo wamabhethri e-lithium-ion. Ama-electrode ebhethri e-lithium ahlukaniswe ngokuyinhloko abe yizigaba ezimbili: izinto zekhabhoni nezinto ezingezona ikhabhoni. Uhlelo lokusebenza olugxile emakethe kakhulu yi-graphite negative electrode material phakathi kwezinto zekhabhoni, phakathi kwazo i-graphite yokwenziwa kanye ne-graphite yemvelo inezinhlelo zokusebenza ezinkulu zezimboni. Ama-electrode ama-electrode asekelwe ku-silicon yiwona okugxilwe kuwo ucwaningo olwenziwe ngabakhiqizi abakhulu bama-electrode angemuhle futhi angenye yezinto ezintsha ezingezinhle zama-electrode okungenzeka zisetshenziswe ngezinga elikhulu esikhathini esizayo.
Amabhethri e-lithiumahlukaniswa abe amabhethri e-lithium cobalt oxide, amabhethri e-lithium iron phosphate, amabhethri e-ternary, njll ngokusho kwezinto ezibonakalayo ze-electrode;
Ngokwefomu lomkhiqizo, zihlukaniswe ngamabhethri ayisikwele, amabhethri angama-cylindrical namabhethri e-soft-pack;
Ngokwezimo zohlelo lokusebenza, zingahlukaniswa ngama-electronics abathengi, ukugcinwa kwamandla kanye namabhethri wamandla. Phakathi kwabo, amabhethri e-lithium abathengi asetshenziswa kakhulu emikhiqizweni ye-3C; amabhethri okugcina amandla asetshenziswa kakhulu ekugcinweni kwamandla kwasendlini futhi asatshalaliswe ukugcinwa kwamandla okuzimele kwesistimu yamandla njengamandla elanga namandla omoya; amabhethri kagesi asetshenziswa kakhulu ezimotweni ezihlukene zikagesi, amathuluzi kagesi nasezimotweni zamandla amasha.
