5. Kuvuta kwa dongosolo la dongosolo: Pakalipano, pambuyo pa kutentha kwa kutentha kwa mabatire a sodium ion, kutaya mphamvu nthawi zambiri kumakhala 1 ~ 2%, zomwe zimapangitsa kuti mphamvu yeniyeni ndi mapangidwe a batri zisagwirizane mokwanira, zomwe zimapangitsa kuti pakhale zovuta kupanga dongosolo;
6. Unyolo wa mafakitale ndi kubwezeretsanso: Monga mchere wachitsulo wa sodium umasungunuka m'madzi, kubwezeretsanso zinthu za sodium m'tsogolomu kuyenera kuganiziridwa pasadakhale;
Ngakhale kuti mafakitale a mphamvu ya sodium akukumanabe ndi zovuta zambiri, kuthamanga kwa chitukuko cha mafakitale onse m'tsogolomu kungapitirire kuyembekezera.Posachedwapa, Wu Hui, manejala wamkulu wa Research Department ya Ivy Economic Research Institute/Dean wa China Battery Industry Research Institute, adati malinga ndi dongosololi, pofika kumapeto kwa chaka chino, mphamvu zopanga zokonzekera zidzafika 40GWh kumapeto kwa chaka chino, ndipo pofika 2025, ndondomeko yonse yamakampani idzafika 300GWh.
Zopindulitsa
Pofika kumapeto kwa 2022, njira yopangira magetsi ya sodium idali yosakwanira, njira yokonzekera inali isanakhwime, ndipo zida zopangira zidali zosakwanira, zomwe zidapangitsa kuti mabatire a sodium asakwaniritsidwe.Posachedwapa, tsogolo la lithiamu carbonate ndi zosankha zalembedwa.Kuchepetsa kwa lithiamu carbonate kwapangitsa kuti batire ya lithiamu ikhale yotsika mtengo.Magetsi a sodium alibe phindu kuposa mtengo wa iron phosphate malinga ndi mtengo wake.
"Potengera kapangidwe ka mphamvu, kukula kwa mabatire a lithiamu-ion wafika pafupifupi 1000GWh.Munthawi yomweyi, mphamvu yopangira zinthu zamagetsi za sodium imatha kuthandizira kupanga mabatire a 2GWH sodium ion.Ndizosatheka kuthandizira kufunikira kwa msika, ndipo nkhani zamtengo wapatali zimapangitsanso makasitomala otsika kapena misika kuti asafune kuyesa teknoloji yatsopano ya sodium.
Pansi pa zovuta zosiyanasiyana, mabatire a sodium sanakwaniritsidwebe kupanga kwakukulu pazachuma.
M'tsogolomu, pofuna kuonetsetsa kuti chitukuko cha magetsi a sodium komanso phindu lenileni, An Weifeng adanena kuti malinga ndi momwe ogulitsa zinthu akumtunda, opanga mabatire apakati, ndi ndondomeko za dziko:
Pankhani ya operekera zida kumtunda, tikulimbikitsidwa kukulitsa kukula kwa zinthu ndikuchepetsa mtengo wopangira zinthu;pamene kukulitsa sikelo kupanga, ikufunikanso kupereka mtanda ndi zopangira zabwino kwambiri kwa mafakitale otsika batire;
Kumbali ya opanga batire yapakatikati, Ndi bwino kugwiritsa ntchito zokonda zotsika mtengo zochepetsera mtengo wa batire;kukhathamiritsa kuchuluka kwa ziyeneretso za mankhwala kuti muwongolere kuyenerera kwazinthu, potero kuchepetsa mtengo wa batri;
Pankhani ya ndondomeko ya dziko, chifukwa batire yamakono ya sodium ion batire ili mu nthawi ya ungwiro, mtengo wa mabatire a sodium ion mu nthawi yochepa sungathebe kutsika kwakukulu.Kugwiritsa ntchito msika kwa mabatire a sodium ion.
Ndi mgwirizano wamakampani omwe atchulidwa pamwambapa, njira zogulitsira zidzakulitsidwa, ndipo mphamvu zopanga ziyamba kukwera.Pankhani yotumiza, kutumiza kwenikweni kwa mabatire a sodium ion chaka chino akuyembekezeka kukhala pafupifupi 3gWh.M'tsogolomu Pakuwongolera, zikuyembekezeredwa kuti kutumiza kwenikweni kwa mabatire a sodium ion kudzafika 347GWh pofika 2030, ndi kukula kwapakati pa 97%.
Kutsiliza: Masiku angapo apitawo, magalimoto amagetsi atsopano okwana 20 miliyoni a mdziko langa alibe intaneti.Kuyambira Januware mpaka Julayi chaka chino, magalimoto atsopano amphamvu mdziko langa adafika pa 4.526 miliyoni, kuwonjezeka kwa 41.7% pachaka, ndipo gawo la msika lidafika 29%, pomwe 636,000 idatumizidwa kunja, kuwonjezeka kwa chaka ndi chaka. 1.5 nthawi;kuchuluka kwathunthu kwa mabatire amphamvu mdziko langa kunali 184.4GWh., Cumulative idakwera ndi 37.3% pachaka, pomwe 67.1GWh idatumizidwa kunja.
Pambuyo pakukula kwazaka zambiri, msika waku China wamagalimoto amagetsi watsopano watha, ndipo kukula kwamakampani a batire a lithiamu kwakhala kokhwima.Pakalipano, kafukufuku ndi chitukuko cha mabatire a sodium ali pamapewa a mabatire a lithiamu pamlingo wina.Inu mukhoza kuchipeza icho.Nthawi yabwino yobzala mtengo ndi zaka khumi zapitazo, kutsatiridwa ndi tsopano, kuzungulira kwatsopano kwa mpweya wa batire kwabwera.Omwe ali oyamba kutumizidwa ndikuumirira pazatsopano zopitilira akhoza kukhala protagonist pamene "kasupe" wa mabatire a sodium abwera.Ndikoyenera kuyang'ana mwachidwi ngati angapite mmwamba.
