Zhang Jiujun, tus xibfwb ntawm Shanghai University, qhia txog tias tam sim no cov roj ntsha lithium-ion tau siv dav, thiab muaj peb hom roj teeb lithium-ion feem ntau rau cov tsheb, lithium-sulfur roj teeb, thiab roj teeb lithium-huab cua.&txiav tawm , lub zog txav thiab lub hnub ua haujlwm txhawm rau txhim kho kev nyab xeeb." Zhang Jiujun tau hais.
Huang Xuejie, tus kws tshawb fawb ntawm lub koom haum ntawm Physics, Suav Academy ntawm Kev Tshawb Fawb, tau qhia txog kev tshawb fawb txog cov khoom siv cobalt tsis pub cov cathode rau cov roj teeb hluav taws xob. Nws qhia tias cov khoom siv ua ntej cobalt thawj-tiam yog lithium manganate, thiab cov khoom siv cob-qib ob-tiam yog lithium iron carbonate. Nickel thiab cobalt ternary roj teeb. Nrog kev nce qib ntawm cov khoom siv thev naus laus zis, txhua tus neeg niaj hnub sim txo cov ntsiab lus ntawm cobalt. Tam sim no, nws tuaj yeem ua tiav uas cov nyiaj cobalt rau 10%, thiab nws yuav raug txo kom 5% yav tom ntej, thiab tom qab ntawd mus rau 3%.
Dong Quanfeng, tus kws tshaj lij ntawm Xiamen University, ntseeg hais tias lub neej tom ntej kev pabcuam kev txhawb zog xav tau kev sib txuas ntawm lub zog txuas ntxiv thiab txuag hluav taws xob txuag hluav taws xob zoo. Lub hom phiaj txhim kho ntawm cov roj teeb hluav taws xob siab tshaj plaws yog los tsim ib hom tshiab ntawm lub tshuab hluav taws xob hauv lub zog hluav taws xob nrog lub zog tshwj xeeb thiab siab zog tshwj xeeb.
GG quot; Feem ntau muaj ob txoj hauv kev siv hluav taws xob hauv lub zog, ib qho yog qhov oxidation-txo cov tshuaj tiv thaiv (ib txwmroj teeb), thiab lwm qhov yog txheej txheem khaws cia thiab tso cov nqi ntawm lub interface (supercapacitor). Peb pab pawg tau tawm tswv yim tshiab Tus Qauv, tom qab kho lub ntsej muag ntawm cov khoom, tuaj yeem ua tiav ob qhov chaw siab thiab muaj peev xwm electrochemically adsorb ntau ntawm ions nyob rau saum npoo, sau qhov khoob hauv thawj ob pawg." Dong Quanfeng hais.
Liang Chengdu, co-president ntawm kev tshawb fawb thiab kev tsim kho ntawm Ningde Times New Energy Technology Co., Ltd. ntseeg hais tias cov pab pawg ua haujlwm tau zoo ntawm cov hluav taws xob cov roj teeb nruab nrog los ntawm CTP yog yav tom ntej kev hloov kho tshiab. Nws muaj ntau qhov zoo, pes tsawg feem raug txo 40%, lub zog ceev tau nce li 10% -15%, thiab lub neej ua haujlwm ncua 10%, tus nqi txo 10%, thiab cov khoom lag luam yog kuj txhim khu kev qha thiab nyab xeeb.
Lu Zhipei, tus lwm thawj coj ntawm Chaw Tsim Khoom Siv Zej Zog Zej Zog Shenzhen ntawm BYD Co., Ltd., tau qhia txog BYD' s thev naus laus zis hauv kev sib xyaw ua ke nrog cov roj teeb hluav taws xob muaj zog. Nws tau hais tias cov roj teeb roj tuaj yeem txo cov ntu ntawm 40%, nce VCTP li 50%, thiab txo tus nqi ntawm tag nrhoroj teebsystem los ntawm 30%." Peb tau nqis peev ntau ntawm kev tshawb nrhiav thiab kev txhim kho ntawm cov roj teeb txhawm, cia siab tias yuav ua tiav cov txiaj ntsig kev sib koom ua ke ntau dua, lub zog siv hluav taws xob ntau dua, kom cov roj teeb hniav muaj ntau dua kev sib tw. Nws xav tias yuav ncav cuag 73% kev koom ua ke kom zoo hauv 2025, thiab lub zog ntim hluav taws xob tuaj yeem ncav 300Wh / kg." Nws hais tias.
