Thaum Lub Ob Hlis 19, nws tau kawm los ntawm Tianjin University tias Xu Yunhua pab pawg, koom tes nrog xibfwb Huang Fei pab pawg los ntawm South China University of Technology thiab lwm lub tsev kawm ntawv, tau ua tiav cov khoom siv cathode tshiab. Cov khoom no kov yeej cov fwj tseem ceeb hauv cov roj ntsha lithium lithium{2}}ion roj teeb, xws li tsis muaj peev xwm thiab nyuaj rau kev siv, ua kom muaj kev nyab xeeb dua, tiv taus txias dua, thiab kub dua - tiv taus. Cov txiaj ntsig kev tshawb fawb cuam tshuam tau luam tawm hauv phau ntawv xov xwm thoob ntiaj teb * Xwm * thaum Lub Ob Hlis 19th (Beijing lub sijhawm).
Lub hnab ntim khoom siv roj teeb nrog lub zog ceev tshaj 250 Wh / kg. Duab qhov chaw: Tianjin University
Organic lithium-Ion roj teeb electrode cov ntaub ntawv muaj dav, thiab lawv cov molecules tuaj yeem tsim tau yooj yim thiab hloov tau yooj yim. Txawm li cas los xij, cov ntaub ntawv no yeej ib txwm tawm tsam kom sib npaug ntawm lub peev xwm siab thiab kev thauj khoom siab, ua rau cov roj teeb uas feem ntau muaj peev xwm tsis txaus lossis them qeeb.
Hauv kev tshawb fawb no, pab pawg ua tiav tau tsim cov khoom siv cathode uas ua ke nrog cov khoom siv hluav taws xob zoo heev, ceev lithium{0}} muaj peev xwm thauj ion, thiab muaj peev xwm khaws cia siab. Raws li cov khoom siv no, pab pawg tau tsim lub hnab ntim cov khoom siv roj teeb nrog lub zog ceev tshaj 250 Wh / kg.
Lub roj teeb no nthuav tawm qhov tshwj xeeb ntawm kev hloov pauv kub, ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias ntawm -70℃txog 80 degree. Nws kuj ua rau pom kev yooj yim thiab kev nyab xeeb, nrog rau nws cov electrodes tseem tshuav tsis tu ncua tom qab khoov, ncab, thiab txawm tias sab nraud compression, tsis muaj kev txo qis hauv roj teeb.
Pab pawg Ah-theem lub hnab roj teeb ua tiav dhau qhov kev ntsuas kev nyab xeeb ntawm cov ntsia hlau nruj, tsis muaj qhov tsis zoo thaum lub sijhawm them thiab tso tawm, yog li xyuas nws qhov kev nyab xeeb. Qhov no yog ib kauj ruam tseem ceeb rau pem hauv ntej rau cov roj teeb organic los ntawm chav kuaj mus rau kev siv tau.
