Intshayelelo:
Iibhetri zinokwahlulwa ngokubanzi zibe ngamacandelo amathathu: iibhetri zeekhemikhali, iibhetri eziphathekayo kunye neebhetri zebhayoloji. Iibhetri zemichiza zezona zisetyenziswa kakhulu kwizithuthi zombane.
Ibhetri yemichiza: Ibhetri yemichiza sisixhobo esiguqula amandla ekhemikhali abe ngamandla ombane ngokusabela kweekhemikhali. Iqukethe i-electrode efanelekileyo kunye ne-negative kunye ne-electrolytes.
Ibhetri ebonakalayo: Ibhetri ebonakalayo iguqula amandla okusebenza (njengamandla elanga kunye namandla omatshini) abe ngamandla ombane ngotshintsho lomzimba.
Ukuhlelwa kwebhetri yeMichiza: Ukusuka kwimbono yesakhiwo, inokwahlulwa ibe ngamacandelo amabini: iibhetri zokugcina (kubandakanywa iibhetri eziphambili kunye neebhetri zesibini) kunye neeseli zepetroli. Iibhetri eziphambili: zinokusetyenziswa kanye kuphela, izinto ezisebenzayo zingenakuguqulwa, ukuzikhupha kuncinci, ukuchasana kwangaphakathi kukhulu, kunye nomthamo okhethekileyo kunye nomthamo othile ophezulu.
Iibhetri zeSekondari: zinokuhlawuliswa kwaye zikhutshwe ngokuphindaphindiweyo, izinto ezisebenzayo zibuyiselwa umva, kwaye zisetyenziswa ngokubanzi kwizixhobo ezahlukeneyo zokutshaja. Uninzi lweemodeli kwimarike okwangoku zisebenzisa iibhetri zesibini ezinokuphinda zitshajwe ukuqhuba isithuthi. Iibhetri zeSekondari zihlulwe zibe ziibhetri ze-lead-acid, iibhetri ze-nickel-cadmium, iibhetri ze-nickel-metal hydride kunye neebhetri ze-lithium ngokwezinto ezahlukeneyo ze-electrode ezintle. Okwangoku, iinkampani zeemoto kwiimarike zisebenzisa ubukhulu becalaiibhetri ze-lithium, yaye abambalwa basebenzisa iibhetri zenickel-metal hydride.
Inkcazo yebhetri ye-lithium
Ibhetri yeLithiumibhetri esebenzisa intsimbi ye-lithium okanye i-lithium alloy njengento efanelekileyo okanye engafanelekanga ye-electrode kunye nesisombululo se-electrolyte esingenamanzi.
Inkqubo yokutshaja kunye nokukhupha ibhetri ye-lithium ikakhulu ixhomekeke ekuhambeni kwe-lithium ion (Li +) phakathi kwe-electrodes efanelekileyo kunye ne-negative. Xa utshaja, i-lithium ion idityanisiwe kwi-electrode efanelekileyo kwaye ifakwe kwi-electrode engafanelekanga nge-electrolyte, kwaye i-electrode engafanelekanga ikwimeko ecebileyo ye-lithium; ngokuchaseneyo kuyinyaniso xa ukhupha.
Umgaqo we-Electrochemical webhetri ye-lithium-ion
Ifomula yempendulo ye-electrode elungileyo: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Ifomula yokusabela kwe-electrode engalunganga: C + xLi+ + xe- → CLix
Iibhetri zeLithium-ion zinoxinzelelo olukhulu lwamandla, ubomi obude kunye nezinga eliphantsi lokuzikhupha, kwaye zisetyenziswa kakhulu kwiifowuni eziphathwayo, iilaptops kunye nezithuthi zombane.
Imimandla yesicelo yeiibhetri ze-lithiumubukhulu becala zahlulwe zangamandla nezingengawo amandla. Imimandla yamandla yezicelo zebhetri ye-lithium-ion ziquka izithuthi zombane, izixhobo zamandla, njl.; amasimi angenamandla aquka i-electronics yabathengi kunye neendawo zokugcina amandla, njl.
Ukuqulunqwa kunye nokuhlelwa kweebhetri ze-lithium
Iibhetri zeLithium ikakhulu zenziwe ngamacandelo amane: izixhobo ze-electrode ezilungileyo, izixhobo ze-electrode ezingalunganga, ii-electrolytes kunye nezahluli zebhetri. Izinto ezingalunganga ze-electrode zichaphazela kakhulu ukusebenza kakuhle kokuqala kunye nokusebenza komjikelo weebhetri ze-lithium-ion. I-electrode engalunganga yebhetri yeLithium yahlulwe kakhulu yangamacandelo amabini: izinto zekhabhoni kunye nezinto ezingezizo ikhabhoni. Esona sicelo sijolise kakhulu kwimarike yigraphite negative electrode material phakathi kwezinto zekhabhoni, phakathi kwazo igraphite eyenziweyo kunye negraphite yendalo zineemveliso ezinkulu. I-electrode engalunganga esekelwe kwi-silicon yingqwalasela yophando ngabavelisi abakhulu be-electrode engalunganga kwaye yenye yezinto ezintsha ezingalunganga ze-electrode ezinokuthi zisetyenziswe kumlinganiselo omkhulu kwixesha elizayo.
Iibhetri zeLithiumzihlelwa kwiibhetri ze-lithium cobalt oxide, iibhetri ze-lithium iron phosphate, iibhetri ze-ternary, njl njl ngokwezinto eziphathekayo ze-electrode;
Ngokwefom yemveliso, zihlulwe zibe ziibhetri zesikwere, iibhetri zecylindrical kunye neebhetri ezithambileyo;
Ngokweemeko zesicelo, zinokwahlulwa zibe yi-electronics yabathengi, ukugcinwa kwamandla kunye neebhetri zamandla. Phakathi kwabo, iibhetri ze-lithium zabathengi zisetyenziswa kakhulu kwiimveliso ze-3C; iibhetri zogcino lwamandla zisetyenziswa ikakhulu kugcino lwamandla endlu kwaye zisasazwe ngokuzimeleyo inkqubo yogcino lwamandla njengamandla elanga kunye nokuveliswa kwamandla omoya; iibhetri zamandla zisetyenziswa ikakhulu kwiimoto ezahlukeneyo zombane, izixhobo zombane kunye nezithuthi zamandla amatsha.
