ELondon, izazinzulu zathi ngoLwesibini babeqala ngqa ukujonga ngaphakathi Ibhetri yeLithium-ion (i-Li-ion) ngexesha lokufudumala, ukuze benze oku basebenzise inkqubo yeX-reyi entsonkothileyo, injongo yayikukuqinisekisa ukuba obu bugcisa bukhuselekile kwixesha elizayo. Namhlanje, amandla eebhetri zeLithium-ion akhona emhlabeni wonke, sizifumana kwiifowuni zethu eziphathwayo, iikhamera, iilaptops kunye. iminyaka embalwa kwi-e-cigarettes. Kwiimeko ezinqabileyo, basenokuba yingozi ngokutshisa okanye ukudubula okunokubangela ukwenzakala okanye nomlilo.
INDLELA YOKUQHUBEKA PHAMBILI KUYILWA KWEBHETRI LI-ION
Ezinye iinqwelomoya zikuthintele ukuthunyelwa kwe Iibhetri ze-Li-on emva kovavanyo lwabonisa ukuba ubukho besiphene kwabanye bunokubangela intshukumo enokuba yintlekele. Kuphononongo olupapashwe kwiphephancwadi elithi "Nature Communications", izazinzulu zabhengeza ukuba ngoku banombono ongcono weengxaki ezinokuvela ngezi bhetri. Ngokutsho kombhali Paul Shearing kwiYunivesithi yaseLondon (UCL) Cette ubuchule obutsha bubonelela ngesakhono sokuvavanya iibhetri ezahlukeneyo kwaye ubone ukuba ziqhuba njani, zithobe kwaye ekugqibeleni zisilele.“. Iqela lithe " Amakhulu ezigidi zeebhetri ze-Li-ion zenziwa minyaka le »Et« ukuba kwakubalulekile ukuqonda okwenzekayo xa iibhetri zabo zisilela kuba ngokucacileyo oko kungundoqo kwinkqubela phambili kuyilo lwabo.".
UKUSHISA OKUGQIBELEYO: INGCACISO NGE UMSEBENZI
Ukusebenzisa udibaniso lwe-X-rays, i-radiography kunye ne-imaging ye-thermal, Ukucheba kunye neqela lakhe bakwazi ukuchaza indlela ukushisa okugqithiseleyo kubangela ukuba iipokotho zegesi zenze ngaphakathi kwebhetri, ukuphazamisa imigangatho yayo yangaphakathi. Ukushisa ngokugqithiseleyo kunokwenzeka ngokusetyenziswa kakubi kombane okanye ngoomatshini okanye phambi komthombo wokushisa wangaphandle. Ukucheba ke ngoko kusicacisela ukuba “ Kuxhomekeke kuyilo lweseli kukho uluhlu lwamaqondo obushushu abalulekileyo athi xa efikelelwe aqalise iziganeko ezingaphaya kwamandla kwaye ke ngoko nobushushu obuninzi. »Emva koko« Nje ukuba isantya sesizukulwana sobushushu sigqithise isantya sokuchitha ubushushu kwindalo esingqongileyo, iqondo lobushushu leseli liqala ukunyuka, ekugqibeleni libangele ukusabela kwekhonkco lokusasaza kweziganeko ezibi ezithi umntu abize " I-Thermal Runaway".
