Nanku kufika i-hardcore! Thatha wena ekuqondeni okubanzi kovavanyo lokungena kwibhetri ye-lithium.
Izithuthi zamandla amatsha ziyindlela yophuhliso lweemoto zexesha elizayo, kwaye enye yezinto eziphambili zezithuthi zamandla amatsha yibhetri yamandla. Okwangoku, kukho iindidi ezimbini kwimarike: ternary lithium kunye lithium iron phosphate. Yeyiphi kwezi ntlobo zimbini zeebhetri esebenzayo kwaye ikhuselekile? Ngaphambili, ibhetri yeblade ye-BYD ibonelele ngempendulo ngesakhono sayo sokuyila eyomeleleyo kunye nokuqokelelana okunzulu kobugcisa. Ngoku, ukhuseleko lwe-ultra-high lwebhetri ye-lithium ye-Kenergy luyinqobile "iNtaba ye-Everest" yentsimi yokuvavanya ibhetri - uvavanyo lokungena kwe-nail. Namhlanje, ndiya kuthetha malunga nokhuseleko lweebhetri ze-lithium ngokusekelwe kuvavanyo lokungena kwe-nail ye-Kenergy lithium ibhetri.
Phambi kokuba sithethe ngovavanyo lokungena kwezikhonkwane, mandiqale ndichaze iindlela zangoku zovavanyo olusemgangathweni lwesizwe lokhuseleko lwebhetri. Kwiimfuno zomgangatho wesizwe wokhuseleko lwebhetri, iingozi ezibangwa ziibhetri zamandla ezithuthi zombane, iipakethi zebhetri, okanye iinkqubo zibandakanya: (1) ukuvuza, okunokukhokelela kumbane ophezulu wenkqubo yebhetri kunye nokusilela kokugquma, ukubangela ngokungangqalanga kubasebenzi umbane. ukothuka, umlilo wenkqubo yebhetri, kunye nezinye iingozi; (2) umlilo, otshisa umzimba womntu ngokuthe ngqo; (3) ugqabhuko-dubulo, olubeka emngciphekweni umzimba womntu ngokuthe ngqo, kubandakanywa ukutshiswa kobushushu obuphezulu, ukwenzakala kwamaza othusayo, kunye nokwenzakala kwamaqhekeza, njl.njl.; (4) ukutshitshiswa kombane, okubangelwa ngumbane odlulayo emzimbeni womntu.
Kutheni uvavanyo lokungena kwezipikili luyimfuneko?
Ngokutsho kwedatha efanelekileyo, ukuthatha iingozi ezidlulileyo zezithuthi zamandla amatsha njengomzekelo, ininzi yeengozi zokutsha ezizenzekelayo ezinxulumene neebhetri zihambelana ngokusondeleyo nokubaleka kwe-thermal yeeseli zebhetri. Ke, yintoni i-thermal runaway? Ukubaleka kobushushu bebhetri kubhekiselele kwimeko apho izinga lokuvelisa ubushushu leentshukumo zekhemikhali zangaphakathi zebhetri liphezulu kakhulu kunesantya sokulahla ubushushu. Ubushushu obuninzi buqokelelana ngaphakathi kwebhetri, nto leyo ebangela ukuba ubushushu bebhetri bunyuke ngokukhawuleza, kwaye ekugqibeleni bubangele ukuba ibhetri ibambe umlilo okanye iqhume.
Uvavanyo lokungena kwesikhonkwane lunokulinganisa zombini iisekethe ezimfutshane zangaphakathi nangaphandle ezikhokelela ekubalekeni kwe-thermal. Okwangoku, kukho izinto ezimbini ezibangela ukubaleka kwe-thermal: enye ibangelwa oomatshini kunye nombane (njengokungena kwezikhonkwane, ukungqubana, kunye nezinye iingozi); enye yizizathu ze-electrochemical (ezifana nokutshaja kakhulu, ukutshaja ngokukhawuleza, iisekethe ezimfutshane ezizenzekelayo, njl. njl.). Emva kokubaleka kwe-thermal yebhetri enye, idluliselwa kwiiseli ezikufutshane, kwaye emva koko isasazeka kwindawo enkulu, ekugqibeleni ikhokelela ekuveleni kweengozi zokhuseleko.
Inkqubo yovavanyo lokungena kwesikhonkwane ayinzima. Ngokwendlela yokuvavanya ukungena kwezikhonkwane echazwe kumgangatho wesizwe, ibhetri kufuneka ihlawulwe ngokupheleleyo, kwaye inaliti yensimbi ye-tungsten isetyenziselwa ukungena ngokuthe nkqo kwibhetri. Amandla onke ebhetri aya kukhutshwa kwindawo yokungena yezikhonkwane ngexesha elifutshane. Inaliti yensimbi ihlala kwibhetri, kwaye ibonwa iyure enye. Kuthathwa njengento efanelekileyo ukuba akukho mlilo okanye ukuqhuma. Phakathi kweemvavanyo ezingaphezulu kwama-300 zokhuseleko lwebhetri ye-lithium, uvavanyo lokungena kwezikhonkwane lubonwa njengeyona nto ingqongqo kwaye inzima yokuvavanya ukhuseleko. Nangona kunjalo, i-Kenergy lithium ibhetri iphumelele ngempumelelo uvavanyo olunzima kakhulu.
"Ukhuseleko oluphezulu" lolona phawu lukhulu lwebhetri ye-lithium ye-Kenergy, kwaye iziphumo zovavanyo zikwangqina oku. Emva kokungena ngokupheleleyo ngenaliti, iqondo lokushisa eliphezulu kakhulu le-Kenergy lithium ibhetri lingaphantsi kwe-50 ° C, kwaye akukho ukutsha okanye ukuqhuma, kwaye akukho msi. Kuyabonakala ukuba le bhetri ikhuselekile kakhulu phantsi kweemeko zesekethe emfutshane.
Itshathi ye-Keneng Lithium yeBattery yokuKhuphuka kweCwava
Ibhetri ye-lithium iron phosphate prismatic esetyenziselwa uvavanyo lothelekiso ayizange ivelise ilangatye elivulekileyo, kodwa kwakukho umsi omninzi, kwaye utshintsho lobushushu lwalucace gca. Ukusebenza kwenye ibhetri ye-lithium ye-ternary iyoyikeka kakhulu: ibhetri ifumene ukusabela kweekhemikhali ezinobundlobongela ngexesha lokungena kwe-nail, ubushushu bomgangatho webhetri bugqithise ngokukhawuleza i-500 ° C, kwaye emva koko yabamba umlilo kwaye yaqhuma. Ukuba oku kwenzeke ngexesha lokuqhuba kwangempela, ingozi yokhuseleko iya kuba nkulu kakhulu.
