Intshayelelo:
Iibhetri zinokwahlulwahlulwa ngokubanzi zibe ziindidi ezintathu: iibhetri zeekhemikhali, iibhetri ezibonakalayo kunye neebhetri zebhayoloji. Iibhetri zeekhemikhali zezona zisetyenziswa kakhulu kwizithuthi zombane.
Ibhetri yekhemikhali: Ibhetri yekhemikhali sisixhobo esiguqula amandla ekhemikhali abe ngamandla ombane ngokusebenzisa ii-chemical reactions. Iqulethe ii-electrodes kunye nee-electrolytes ezilungileyo nezingalunganga.
Ibhetri ebonakalayo: Ibhetri ebonakalayo iguqula amandla abonakalayo (afana namandla elanga kunye namandla oomatshini) abe ngamandla ombane ngokusebenzisa utshintsho olubonakalayo.
Ulwahlulo lweebhetri zekhemikhali: Ngokwembono yesakhiwo, lunokwahlulwahlulwa lube ziindidi ezimbini: iibhetri zokugcina (kuquka iibhetri eziphambili kunye neebhetri zesibini) kunye neeseli zepetroli. Iibhetri eziphambili: zingasetyenziswa kube kanye kuphela, izinto ezisebenzayo azinakuguqulwa, ukuzikhupha zincinci, ukumelana kwangaphakathi kukhulu, kwaye umthamo othile wobunzima kunye nomthamo othile uphezulu.
Iibhetri zesibini: zinokutshajwa kwaye zikhutshwe ngokuphindaphindiweyo, izinto ezisebenzayo ziyajikwa, kwaye zisetyenziswa kakhulu kwizixhobo ezahlukeneyo zokutshaja. Uninzi lweemodeli ezikwimarike okwangoku zisebenzisa iibhetri zesibini ezinokutshajwa kwakhona ukuqhuba imoto. Iibhetri zesibini zahlulwe zaba ziibhetri ze-lead-acid, iibhetri ze-nickel-cadmium, iibhetri ze-nickel-metal hydride kunye neebhetri ze-lithium ngokwezixhobo ezahlukeneyo ze-electrode ezilungileyo. Okwangoku, iinkampani zeemoto ezikwimarike zisebenzisa kakhulu iibhetri ze-lithium, kwaye ezimbalwa zisebenzisa iibhetri ze-nickel-metal hydride.
Inkcazo yebhetri ye-lithium
Ibhetri yeLithium yibhetri esebenzisa i-lithium metal okanye i-lithium alloy njengezinto ze-electrode ezilungileyo okanye ezimbi kunye nesisombululo se-electrolyte esingengomanzi.
Inkqubo yokutshaja nokukhupha ibhetri ye-lithium ixhomekeke kakhulu ekushukumeni kwee-ion ze-lithium (Li+) phakathi kwee-electrodes ezilungileyo nezingalunganga. Xa kutshaja, ii-ion ze-lithium ziyasuswa kwi-electrode elungileyo kwaye zifakwe kwi-electrode engalunganga nge-electrolyte, kwaye i-electrode engalunganga ikwimeko ye-lithium-rich; okuchaseneyo kuyinyaniso xa kutshaja.
Umgaqo we-electrochemical webhetri ye-lithium-ion
Ifomula yokusabela kwe-electrode elungileyo: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Ifomula yokusabela kwe-electrode engalunganga: C + xLi + + xe- → CLix
Iibhetri zeLithium-ion zinamandla amaninzi, zihlala ixesha elide kwaye azikwazi ukuzikhupha, kwaye zisetyenziswa kakhulu kwiifowuni eziphathwayo, iilaptops kunye nezithuthi zombane.
Iindawo zokusetyenziswa kweebhetri ze-lithium-ion zahlulwe ngokubanzi zibe ngamandla kunye nezingezizo zamandla. Iindawo zokusetyenziswa kweebhetri ze-lithium-ion ziquka izithuthi zombane, izixhobo zamandla, njl.njl.; iindawo ezingezizo zamandla ziquka izixhobo ze-elektroniki zabathengi kunye neendawo zokugcina amandla, njl.njl.
Ukwakhiwa kunye nokuhlelwa kweebhetri ze-lithium
Iibhetri zeLithium-ion zenziwe ikakhulu ngamacandelo amane: izinto ze-electrode ezilungileyo, izinto ze-electrode ezimbi, ii-electrolytes kunye nabahluli bebhetri. Izinto ze-electrode ezimbi zichaphazela kakhulu ukusebenza kakuhle kokuqala kunye nokusebenza komjikelo weebhetri ze-lithium-ion. Ii-electrode ezimbi zebhetri yeLithium zahlulwe ngokubanzi zibe ziindidi ezimbini: izinto zekhabhoni kunye nezinto ezingezizo zekhabhoni. Eyona sicelo sijolise kakhulu kwimarike zizinto ze-electrode ezimbi ze-graphite phakathi kwezinto zekhabhoni, phakathi kwazo i-graphite yokwenziwa kunye ne-graphite yendalo zinezicelo ezinkulu zoshishino. Ii-electrode ezimbi ezisekelwe kwiSilicon zigxile kuphando olwenziwe ngabavelisi abakhulu be-electrode ezimbi kwaye zezinye zezinto ezintsha ze-electrode ezimbi ezinokuthi zisetyenziswe kakhulu kwixesha elizayo.
Iibhetri zeLithium-ion zahlulwe zibe ziibhetri zeLithium Cobalt oxide, iibhetri zeLithium Iron phosphate, iibhetri zeTerry, njl. ngokwezixhobo zeElectrode ezilungileyo;
Ngokwendlela imveliso ebhalwe ngayo, zahlulwe zibe ziibhetri ezisikwere, iibhetri ezisilinda kunye neebhetri ezithambileyo;
Ngokweemeko zesicelo, zinokwahlulwa zibe zii-elektroniki zabathengi, ugcino lwamandla kunye neebhetri zamandla. Phakathi kwazo, iibhetri ze-lithium zabathengi zisetyenziswa kakhulu kwiimveliso ze-3C; iibhetri zokugcina amandla zisetyenziswa kakhulu kwiindawo zokugcina amandla zasekhaya kunye neendawo zokugcina amandla ezizimeleyo ezifana namandla elanga kunye nokuveliswa kwamandla omoya; iibhetri zamandla zisetyenziswa kakhulu kwiimoto ezahlukeneyo zombane, izixhobo zombane kunye nezithuthi ezintsha zamandla.
