Kwiminyaka yakutshanje, imililo yezithuthi zombane ezinamavili amabini isaqhubeka isanda, ingakumbi ehlotyeni xa kushushu kakhulu, umlilo wombane kulula ukuwutshisa ngequbuliso!
Ngokutsho kweqela lesizwe lokuhlangula umlilo lika-2021 elifumana idatha yamapolisa kunye nomlilo ekhutshwe yi-Fire Rescue Bureau yeSebe loLawulo lweeNgxamiseko, phantse imililo eli-18,000 ebangelwe zizithuthi zombane ezinamavili amabini kunye nokungasebenzi kweebhetri zazo ibikwe kuzwelonke, yabulala abantu abangama-57. Ngokweengxelo, kwisiqingatha nje sonyaka ka-2022 kulo nyaka, bekukho imililo engama-26 yezithuthi zombane ezinamavili amabini eYantai.
Yintoni ebangela ukuba iimoto zombane ezinamavili amabini ziqhume rhoqo kangaka?
Oyena nobangela wokutsha okuzenzekelayo kwesithuthi sombane esinamavili amabini kukutsha kwebhetri ye-lithium, okubizwa ngokuba yi-thermal runaway yindlela eyenzeka ngayo i-chain reaction ebangelwa zizikhuthazo ezahlukeneyo, kwaye ubushushu bungenza ubushushu bebhetri bunyuke ngamawaka eedigri, nto leyo ebangela ukutsha okuzenzekelayo. Ibhetri yesithuthi sombane esinamavili amabini itshaja kakhulu, i-puncture, ubushushu obuphezulu, i-short circuit, umonakalo wangaphandle kunye nezinye izizathu zibangela ukutsha kwe-thermal runaway ngokulula.
Indlela yokuthintela ukuhamba kobushushu ngokufanelekileyo
Ukukhuthaza ukufuduka kobushushu kuninzi, ngoko ke kufuneka kwenziwe amanyathelo okuthintela ukwenzeka kokufuduka kobushushu.
Eyona nto ibangela ukuba ibhetri ingasebenzi kakuhle kubushushu obufanelekileyo, ukuqinisekisa ukuba ibhetri isebenza kubushushu obufanelekileyo, ukuze kuthintelwe ngempumelelo ukuba ibhetri ingasebenzi kakuhle. Nangona kunjalo, kubushushu obuphezulu ehlotyeni, “ubushushu” abunakuphepheka, kufuneka uqale kwibhetri, ukuze iibhetri ze-lithium-ion zibe nokumelana nobushushu okungcono kunye nokusebenza kakuhle kokusasaza ubushushu.
Okokuqala, abathengi kufuneka baqwalasele iimpawu ezinxulumene neebhetri ze-lithium xa bethenga izithuthi zombane ezinamavili amabini, nokuba ingaba izinto zangaphakathi zeseli yebhetri zinokumelana kakuhle nobushushu kunye nokusebenza kakuhle kokusasaza ubushushu. Okwesibini, ukuba ingaba isixhumi esiqhagamshelwe kwibhetri ngaphakathi kwisithuthi sombane sisebenza njani ukumelana nobushushu obuphezulu, ukuqinisekisa ukuba isixhumi asiyi kuthamba kwaye singaphumeleli ngenxa yobushushu obuphezulu, ukuze kuqinisekiswe ukuba isekethe igudile kwaye kuthintelwe ukwenzeka kwesekethe emfutshane.
Njengengcali yobuchwephesha bokudibanisa izithuthi zombane, i-AmasS inamava eminyaka engama-20 kuphando nophuhliso lwezihlanganisi zezithuthi zombane ze-lithium, kwaye ibonelela ngezisombululo zokudibanisa ezithwala umbane kwiinkampani zezithuthi zombane ezineevili ezimbini ezifana ne-SUNRA, i-AIMA, ne-YADEA. Isihlanganisi sezithuthi zombane ezineevili ezimbini esinobushushu obuphezulu sisebenzisa i-PBT enokumelana nobushushu, ukumelana nemozulu kunye neempawu ezilungileyo zombane, kwaye iqondo lokunyibilika kwegobolondo leplastiki eligqunywe yi-PBT yi-225-235℃.
Ukusebenza okusemgangathweni okuqinileyo kunye nemigangatho yovavanyo egqibeleleyo sisiseko sokuqinisekisa umgangatho wesixhumi sombane esinamavili amabini
Ilebhu ye-Amass
Izixhumi zombane ezinevili ezimbini ezinobushushu obuphezulu ziphumelele uvavanyo lwenqanaba lokurhoxisa ilangatye, ukusebenza kokurhoxisa ilangatye ukuya kuthi ga kwi-V0, zinokufikelela kubushushu obuphakathi be -20 ° C ~ 120 ° C. Ukusetyenziswa kuluhlu lobushushu obuphakathi olungentla, iqokobhe eliphambili lesixhumi sombane esinevili ezimbini asiyi kuthamba ngenxa yobushushu obuphezulu, nto leyo ebangela ukuba kubekho i-short circuit.
Ukongeza ekukhetheni ibhetri kunye nezinto ezikuyo, umgangatho wetshaja yesithuthi sombane, ixesha lokutshaja lide kakhulu, kunye nokuguqulwa okungekho mthethweni kwesithuthi sombane esinamavili amabini ngundoqo ekuphuculeni ukusebenza kokhuseleko lwebhetri ye-lithium yesithuthi sombane.
