Mabatire a lithiamu ali paliponse pantchito yathu ndi moyo wathu.Kuchokera ku zipangizo zamagetsi monga mafoni a m'manja ndi ma laputopu kupita ku magalimoto atsopano amphamvu, mabatire a lithiamu-ion amapezeka muzochitika zambiri.Ndi kukula kwawo kocheperako, magwiridwe antchito okhazikika, komanso kubwezeredwa bwino, zimathandiza anthu kugwiritsa ntchito bwino mphamvu zoyera.
M'zaka zaposachedwa, China yalowa patsogolo padziko lonse lapansi pakufufuza ndi chitukuko chaukadaulo, kukonzekera zinthu, kupanga batire komanso kugwiritsa ntchito mabatire a sodium ion.
Ubwino waukulu wosungira
Pakalipano, kusungirako kwamagetsi a electrochemical omwe akuimiridwa ndi mabatire a lithiamu-ion akufulumizitsa chitukuko chake.Mabatire a Lithium ion ali ndi mphamvu zenizeni zenizeni, mphamvu zenizeni, mphamvu zotulutsa mphamvu, ndi magetsi otulutsa, ndipo amakhala ndi moyo wautali wautumiki komanso kudzitulutsa pang'ono, zomwe zimawapangitsa kukhala ukadaulo woyenera wosungira mphamvu.Ndi kuchepetsa ndalama zopangira, mabatire a lithiamu-ion akuyikidwa pamlingo waukulu m'malo osungiramo mphamvu zamagetsi, ndikukula kwamphamvu.
Malinga ndi deta ya Unduna wa Zamakampani ndi Information Technology, latsopano anaika mphamvu yosungirako mphamvu zatsopano ku China chinawonjezeka ndi 200% chaka ndi chaka mu 2022. Ntchito zoposa 20 mazana megawati mlingo akwaniritsa gululi olumikizidwa ntchito, ndi lifiyamu batire. Kusungirako mphamvu kuwerengera 97% ya mphamvu zonse zatsopano zomwe zayikidwa.
"Tekinoloje yosungiramo mphamvu ndi njira yolumikizirana ndikugwiritsa ntchito njira yatsopano yosinthira mphamvu.Pankhani ya njira ziwiri zopangira kaboni, kusungirako mphamvu zatsopano ku China kwakula mwachangu. ”Sun Jinhua, katswiri wa maphunziro a European Academy of Sciences ndi pulofesa pa yunivesite ya Science and Technology ya China, ananena momveka bwino kuti panopa zinthu zosungirako mphamvu zatsopano zikulamulidwa ndi "lifiyamu imodzi".
Pakati pa matekinoloje ambiri osungira mphamvu zamagetsi, mabatire a lithiamu-ion atenga malo otsogola pazipangizo zamagetsi zamagetsi ndi magalimoto amagetsi atsopano, ndikupanga unyolo wathunthu wamafakitale.Komabe, panthawi imodzimodziyo, zofooka za mabatire a lithiamu-ion zakopanso chidwi.
Kuperewera kwa zinthu ndi chimodzi mwa izo.Akatswiri amanena kuti ku dziko lonse, kugawa chuma lifiyamu ndi wosagwirizana kwambiri, ndi pafupifupi 70% anagawira ku South America, ndi chuma China lifiyamu chifukwa 6% ya okwana dziko.
Momwe mungapangire ukadaulo wa batri wosungira mphamvu zomwe sizidalira zinthu zachilendo komanso zotsika mtengo?Kukwera kwamatekinoloje atsopano osungira mphamvu omwe akuimiridwa ndi mabatire a sodium ion akuchulukirachulukira.
Mofanana ndi mabatire a lithiamu-ion, mabatire a sodium ion ndi mabatire achiwiri omwe amadalira ma ion a sodium kuti asunthire pakati pa ma electrode abwino ndi oipa kuti amalize kuyendetsa ndi kutulutsa.Li Jianlin, Mlembi Wamkulu wa Energy Storage Standards Committee of the Chinese Electrotechnical Society, adati padziko lonse lapansi, nkhokwe za sodium zimaposa zinthu za lithiamu ndipo zimafalitsidwa kwambiri.Mtengo wa mabatire a sodium ion ndi 30% -40% wotsika kuposa mabatire a lithiamu.Panthawi imodzimodziyo, mabatire a sodium ion amakhala ndi chitetezo chabwino komanso kutentha kwapansi, komanso moyo wautali wautali, kuwapangitsa kukhala njira yofunikira ya teknoloji yothetsera ululu wa "lithiyamu imodzi imalamulira".
Zoyembekeza zabwino zamakampani
China imawona kufunikira kwakukulu pakufufuza ndi kugwiritsa ntchito mabatire a sodium ion.Mu 2022, China iphatikiza mabatire a sodium ion mu 14th Year Plan for Science and Technology Innovation in the Energy Field, kuthandizira kafukufuku ndi chitukuko cha matekinoloje apamwamba komanso zida zaukadaulo zamabatire a sodium ion.Mu Januware 2023, Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso ndi madipatimenti ena asanu ndi limodzi adapereka limodzi Malingaliro Otsogolera pa Kupititsa patsogolo Kukula kwamakampani amagetsi amagetsi, kumveketsa bwino kulimbikitsa kupita patsogolo kwaukadaulo pakukulitsa mabatire atsopano osungira mphamvu, kafukufuku ndi zotulukapo zazikulu. matekinoloje monga moyo wautali wautali ndi machitidwe a batri otetezeka, zazikulu, mphamvu zazikulu, ndi kusunga mphamvu moyenera, ndikufulumizitsa kafukufuku ndi chitukuko cha mitundu yatsopano ya mabatire monga mabatire a sodium ion.
Yu Qingjiao, Mlembi Wamkulu wa Zhongguancun New Battery Technology Innovation Alliance, adanena kuti 2023 imadziwika kuti "chaka choyamba cha kupanga kwakukulu" kwa mabatire a sodium pamakampani, ndipo msika wa batri wa sodium waku China ukukulirakulira.M'tsogolomu, mabatire a sodium adzakhala chowonjezera champhamvu ku teknoloji ya batri ya lithiamu m'magulu angapo ang'onoang'ono monga magalimoto amagetsi a mawilo awiri kapena atatu, kusungirako mphamvu zapakhomo, kusungirako mphamvu zamafakitale ndi malonda, ndi magalimoto atsopano amagetsi.
Mu Januware chaka chino, galimoto yaku China ya Jianghuai Yttrium idapereka batire yoyamba ya sodium padziko lonse lapansi.Mu 2023, ma cell a batri a sodium ion m'badwo woyamba wa CATL adakhazikitsidwa ndikutera.Selo la batri limatha kuyimbidwa kutentha kwa mphindi 15, ndi batri yopitilira 80%.Sikuti mtengo wake ndi wotsika, koma unyolo wamakampaniwo udzakwaniritsanso kulipiritsa kodziyimira pawokha komanso kowongolera.
Kumapeto kwa chaka chatha, National Energy Administration idalengeza projekiti yoyeserera yosungira mphamvu zatsopano.Mwa ma projekiti 56 omwe asankhidwa, pali ma projekiti awiri a sodium ion batri.Malinga ndi Wu Hui, Purezidenti wa China Battery Industry Research Institute, njira yopangira mafakitale yamabatire a sodium ion ikukula mwachangu.Malinga ndi kuwerengetsa, pofika chaka cha 2030, kufunika kosungirako mphamvu padziko lonse lapansi kudzafika pafupifupi maola 1.5 a terawatt (TWh), ndipo mabatire a sodium ion akuyembekezeka kupeza msika waukulu."Kuchokera ku grid level kusungirako mphamvu zosungiramo mphamvu zamafakitale ndi zamalonda, kenako kusungirako mphamvu zapakhomo ndi zonyamula, zonse zosungiramo mphamvu zamagetsi zidzagwiritsa ntchito kwambiri magetsi a sodium m'tsogolomu," adatero Wu Hui.
Njira yayitali yogwiritsira ntchito
Pakadali pano, mabatire a sodium ion akulandira chidwi kuchokera kumayiko osiyanasiyana.Nihon Keizai Shimbun kamodzi adanenanso kuti pofika Disembala 2022, ma Patent aku China pamabatire a sodium ion anali opitilira 50% pazabwino zonse zapadziko lonse lapansi, ndipo Japan, United States, South Korea ndi France adakhala wachiwiri mpaka wachisanu motsatana.Sun Jinhua adanenanso kuti kuwonjezera pa China kufulumizitsa bwino ntchito yopambana ndi kugwiritsa ntchito kwakukulu kwa teknoloji ya sodium ion batri, mayiko ambiri a ku Ulaya, America ndi Asia aphatikizanso mabatire a ion sodium mu dongosolo lachitukuko la mabatire osungira mphamvu.
