Posachedwapa, malo oyamba osungira mphamvu a batire ya sodium-ion ku China - malo osungira mphamvu a batire ya sodium-ion a Volin adakhazikitsidwa ku Nanning, Guangxi. Iyi ndi pulogalamu yofunika kwambiri yofufuza ndi chitukuko cha dziko lonse ya "ukadaulo wosungira mphamvu wa batire ya sodium-ion wa maola 100 megawatt" yowonetsera gawo loyamba la pulojekitiyi, kukula kwake kwa ma megawatts 2.5/ma megawatts 10.
Malo opangira magetsiwa amayikidwa ndalama ndikumangidwa ndi Guangxi Power Grid Company ya Southern Power Grid, ndipo kukula kwa gawoli ndi 10 MWh. Kukula konse kwa polojekitiyi kudzafika 100 MWh, komwe kumatha kupanga madigiri 73 miliyoni amagetsi oyera pachaka. Malo opangira magetsiwa amayikidwa ndalama ndikumangidwa ndi Guangxi Power Grid Company ya Southern Power Grid, ndipo kukula kwa gawoli ndi 10 MWh. Kukula konse kwa polojekitiyi kudzafika 100 MWh, komwe kumatha kupanga madigiri 73 miliyoni amagetsi oyera pachaka, motero kuchepetsa kutulutsa kwa carbon dioxide ndi matani 50,000, ndikukwaniritsa zosowa za magetsi za ogwiritsa ntchito nyumba 35,000.
Poyerekeza ndi malo osungira mphamvu a batri ya lithiamu-ion, malo osungira mphamvu a batri ya "abale" sodium-ion, osavuta kutulutsa, otsika mtengo, amagwira ntchito bwino kutentha kochepa, komanso amasunga mphamvu zambiri ali ndi ubwino woonekeratu. "Kusungira mphamvu kwa batri ya sodium-ion pamlingo wa chitukuko, mtengo wake ukhoza kuchepetsedwa ndi 20% mpaka 30%, pansi pa mfundo yoti batri ikonzedwe bwino, iwonjezere kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito komanso moyo wa nthawi yozungulira, ndipo mtengo wamagetsi ukhoza kufufuzidwa kufika pa 0.2 yuan / kWh, ndikulimbikitsa kugwiritsa ntchito njira yatsopano yosungiramo zinthu zofunika kwambiri paukadaulo," adatero Chen Man, wachiwiri kwa mlembi wamkulu wa National Electric Power Storage Technical Committee komanso katswiri waukadaulo wa Southern Power Grid.
Ngakhale kuti ntchito ya China mu kafukufuku ndi chitukuko, kupanga, kuyika miyezo, kukweza msika ndi kugwiritsa ntchito zinthu za mabatire a sodium-ion ikuyenda bwino, palibe chitsanzo chapadziko lonse lapansi chogwiritsa ntchito ukadaulo wa mabatire a sodium-ion ku malo opangira magetsi akuluakulu.
Mu Novembala 2022, Guangxi Power Grid Company, mogwirizana ndi South Grid Energy Storage Company, Institute of Physics of the Chinese Academy of Sciences, Zhongkehai Sodium Technology Co., Ltd. ndi mayunitsi ena a gulu la polojekitiyi, adayambitsa mwalamulo pulojekiti yofunika kwambiri yofufuza ndi chitukuko cha dziko lonse ya mutu wakuti "100 megawatt-hour sodium-ion battery energy storage system integration technology and application demonstration" kafukufuku. "Timayang'ana kwambiri kukonzekera bwino kwa magetsi, kuphatikiza makina ndi kupewa chitetezo ndi kuwongolera ndi ukadaulo wina wofunikira kuti tichite kafukufuku, wopangidwa ndi ufulu wodziyimira pawokha waukadaulo wa kukonza batri ya sodium-ion ndi ukadaulo wophatikiza makina," mtsogoleri wa polojekitiyi, South China Grid Guangxi Grid Company, wachiwiri kwa director wa Dipatimenti Yopanga Zinthu Zatsopano Gao Lik adayambitsa.
Selo ya batri yokhala ndi mphamvu zambiri ndiyo gawo loyambira la dongosolo lonse la batri ya sodium-ion. Pambuyo pa chaka chimodzi ndi theka la kafukufuku, gulu la polojekitiyi linapanga batri yoyamba padziko lonse lapansi yosungira mphamvu ya sodium-ion, yokhala ndi moyo wautali, kutentha kwakukulu, komanso chitetezo champhamvu cha 210Ah sodium-ion. "Malinga ndi momwe zinthu zilili, batri yathu ya sodium-ion ili ndi ubwino wa kutentha kwakukulu, kuyatsa mwachangu komanso kuchuluka kwabwino, ndipo imatha kuchajidwa mpaka 90% mumphindi 12," adatero Hu Yongsheng, wofufuza ku Institute of Physics, Chinese Academy of Sciences.
Monga otenga nawo mbali paukadaulo waukulu mu polojekitiyi, SouthGrid Energy Storage Company Energy Storage Research Institute mu kuphatikiza ndi kuteteza chitetezo cha mabatire a lithiamu, ili ndi chidziwitso chochuluka pa kafukufuku, ikuchita pulogalamu yayikulu yofufuza ndi chitukuko cha dziko lonse "kugwiritsa ntchito ukadaulo wachitetezo cha mabatire a lithiamu-ion". "Ngakhale mfundo za momwe mabatire a sodium ndi lithiamu amagwirira ntchito ndizofanana, kupanga njira yonse yosungira mphamvu yomwe imaphatikiza mawonekedwe a kuyatsa ndi kutulutsa mabatire a sodium kumafuna kuthana ndi zovuta zambiri zatsopano," adatero Li Yongqi, katswiri waukadaulo wochokera ku SouthGrid Energy Storage Company, wokhala ndi malingaliro.
Potengera kuphatikiza kwa makina monga chitsanzo, gulu la polojekitiyi likugwiritsa ntchito mwaluso kapangidwe ka malo osungira mphamvu ogawidwa kutengera mphamvu yamagetsi ya mabatire a sodium-ion, ndipo makina onsewa amaphatikiza ma modular converter 88, zomwe zimapangitsa kuti "kulumikizana kwa munthu ndi munthu" ndi magulu a mabatire, pomwe kapangidwe kachikhalidwe ka makina osungira mphamvu a lithiamu-ion kamafunika kuphatikiza ma converter opitilira 40. Cholinga chachangu chowirikiza kawiri chiwerengero cha ma converter ndikuwonjezera kupezeka kwa mphamvu ndi mphamvu yosinthira mphamvu. Mphamvu yonse yosinthira mphamvu ya makina osungira mphamvu a batire ya sodium iyi ndi yoposa 92%, pomwe mabatire a lithiamu nthawi zambiri amakhala ochepera 90%, omwe akuyembekezeka kuti azikwaniritsa ndikusintha mabatire a lithiamu bwino, ndikugwiritsidwa ntchito posungira mphamvu zamagetsi zamagetsi, magalimoto amagetsi, makina omanga ndi madera ena.
Ponena za kupewa ndi kuwongolera chitetezo, gululi lapanga njira yoyendetsera kutentha kwa makina oziziritsira madzi komanso njira zonse zopewera ndi kuwongolera moto pamakina osungira mphamvu a batri ya sodium-ion, monga chotchinga kutentha cha module-level ndi kuzimitsa moto moyenera.
Kusiyana kwa kutentha pakati pa maselo opitilira 22,000 a sodium batteries m'dongosolo lonse kumayendetsedwa mkati mwa madigiri 3 Celsius. Kugwiritsa ntchito njira yochotsera kutentha komanso chotchinga cha kutentha.bulangeti la airgel la galasiMonga chotchinga kutentha pakati pa pakati pa magetsi, nthawi yofalikira ya monomer ya batri ndi mphindi 30 mpaka maola awiri, imakulitsidwa mpaka nthawi 4, zomwe zimapangitsa kuti chitetezo cha gawo la batri chikhale bwino.
Gululi linapanga ukadaulo wozimitsa moto wamadzimadzi, woziziritsa, woletsa kuyaka, wokhoza kuzimitsa moto woyambirira wa batri mkati mwa masekondi 5, kuti ugwire maola 24 popanda kuyakanso ndi kuphulika. "Ukadaulo wamakono wosungira mphamvu wa lithiamu ndi sodium kuti ulimbikitse kusintha kwa makhalidwe a wina ndi mnzake, kafukufuku wa makina osungira mphamvu a batri a sodium-ion ndi ukadaulo wothandiza wozimitsa moto wamadzimadzi, wozizira, woletsa kuyaka kudzera mu makina osungira mphamvu a batri a lithiamu-ion moyo wonse wa ntchito yaukadaulo wosintha ntchito mu lithiamu, sodium mphamvu yosungira mphamvu yolumikizirana koyamba mu ntchito yaukadaulo," adatero LiYongQi.
Pa Januwale 28, 2024, ndi katswiri wa maphunziro a ku Chinese Academy of Engineering Jiang Jianchun, katswiri wa maphunziro a ku Chinese Academy of Sciences, katswiri wa maphunziro a Cheng Shijie, katswiri wa maphunziro a Zhang Yue, katswiri wa maphunziro a ku European Union Academy of Sciences Sun Jinhua ndi akatswiri ena a Komiti Yowunikira ya China Machinery Industry Federation pa zotsatira za polojekitiyi kuti ayang'anenso kuwunika: ukadaulo wonse wa "10 MWh sodium ion battery energy storage system for electric energy storage stations" womwe wapangidwa ndi gulu la polojekitiyi uli pamlingo wotsogola padziko lonse lapansi.
