1. Kupambana kwa tekinoloje: Kuthereska Viyezgo vya Mafakitale Nthowa yakuguliskira mabatire gha sodium-ion kwa nyengo yitali yatondeka chifukwa cha malonda ghakugwira ntchito-offs mu vinthu vinyake vyakuzirwa. Hard carbon anodes, chigaŵa chakukhumbikwa chomene, chikakumana na kugaŵikana kwa chibadwa pakati pa kukwaniska kukwaniska kuzgoka kwakukwana, kugwira ntchito kwakwamba kwa Coulombic, na kukhora kwa mpopi. Suzgo ili sono likutondeka. Gulu ilo likalongozgekanga na Pulofesa Yufeng Zhao ku yunivesite ya Shanghai likapanga ndondomeko yiphya yakuti “Kusintha kwa Vinthu Vinyake Kupangiska kuti Vinthu Viŵe Vinthu Vinyake Vindachitike.” Pakulongozga ndondomeko ya kuthandazgika kwa mphepo, ŵakakhozga makora vigaŵa vyose vitatu vyakuzirwa vya carbon wakukhora pa nyengo yimoza, ndipo ivi vikapangiska kuti ŵalute panthazi. Mwakuyana waka, gulu lakufufuza ilo likalongozgekanga na Musambizgi Tianshou Zhao pa Yunivesite ya Southern ya Sayansi na Tekinoloje likapanga mbiri yakuzizika comene. Nga umo vikalembekera mu nyuzipepara ya Energy & Environmental Science, ŵakapanga chinthu chakupangika na polyanion. Cathode iyi yikalongora kuti yikukhala nyengo yitali chomene, ndipo yikakwaniska kuzungulira nyengo zakujumpha 100,000 pa mlingo ukuru wa 100C uku yikusunga 72.6% ya nkhongono zake-kujumpha chomene umoyo wa mabatire gha lithiamu gha malonda gha SIBenti'al {{18} mapulogalamu gha umoyo utali-. Kafukufuku wa pa charu chose wakuchitika mwaluŵiro. Ŵasayansi ŵa ku Brown University ŵakavumbura vinthu viphya vyakukhwaskana na umo sodium yikuchitira mu mabatire, ndipo ŵakapeleka nthowa yiphya yakupangira vinthu vya anode kuti viŵe vyakukhora ndiposo kuti viŵe na nkhongono zinandi. Pa nyengo iyi, ŵakusanda ŵa ku Western University ku Canada ŵakapanga batire la sodium lakukhora chomene mwakugwiliskira ntchito sulfure na chlorine, ndipo ivi vikapangiska kuti sodium yiŵe yakukhora ndiposo kuti yiŵe yakuvikilirika.
2. Kukwezga: Nkhongono Yakupanga Yikuwoneka Kupangika na vinthu ivi vya R&D, mafakitale gha mabatire gha sodium-ion ghakukura mwaluŵiro. EVE Energy yaŵika makora na kwamba kugwira ntchito ya malonda ya nthowa yake yakwamba yakusungirako nkhongono za mabatire gha sodium - ion pa malo ghake gha Jingmen. Nthowa iyi yikugwiriskira ncito maselo gha NF155L gha sodium - ion ghakuthemba pa nthowa ya NFPP (sodium iron phosphate), ghakujilumba na civikiliro cikuru, mtundu ukuru wa kutentha kwakugwira nchito, nkhongono yikuru ya mlingo, umoyo utali wa msinkhu, na kucepeska mphepo za carbon. Kweniso, gulu la Guangde Qingna Technology Co., Ltd. Na ndalama zose zakukwana 6 biliyoni RMB, ntchito iyi yiwovwirenge Suining kusintha kufuma ku "lithiamu - yekha" kuŵika mtima pa "lithiamu - sodium kaŵiri - drive" ndondomeko. Nangauli wakakhazikiskika mu Ogasiti 2023, Qingna Tech walongora kuti wakukura chomene, mwambura kurongosora wakusunga vigaŵa mu makampani 9 kwizira mu makampani ghake ghachoko ndipo wakusanga ndalama zakujumpha 100 miliyoni RMB mu Pre-A ndalama zakulongozgeka na Yunhe Fangyuan Capital mu Januwale wa ye uno.
3. Uwemi Wakuzirwa: Phindu Lakuzirwa la Mtengo wa Vinthu Vyakupangika Kukura kwa chimwemwe pafupi na mabatire gha sodium - ion kukukhazikika chomene mu uwemi wawo wakubabikira. Chikalata chasonosono cha tekinoloje kufuma ku wupu wa International Renewable Energy Agency (IRENA) chikuŵika ma SIB kuti ni nthowa yiwemi yakusinthira ma LIB, iyo yingakwaniska kuchepeska kuthemba pa mchere wakukhumbikwa chomene na kukhozga nkhongono za mtundu wa mabatire gha pa charu chose. Uwemi ukuru uli mu unandi wa vinthu vyakukhumbikwa na mtengo wake. Kuchuluka kwa sodium kwa 2.74%, kukukwera chomene kuluska lithiamu 0.0065%. Iwo ukugaŵika chomene ndipo ngwambura kusuzga kusanga, ndipo ivi vikupangiska kuti mtengo wa vyakupangira uŵe wakukhazikika ndiposo wakucepa. EVE Energy yikuti umoyo wose-mzere wa carbon uwo ukufumiskika mu maselo ghake gha NF155L ukujumpha 42% pasi pa uwo uli mu mabatire gha lithiamu -ion. Maselo ghakovwiraso pa nyengo yakuzizima yakugwira ntchito kufuma pa -40℃kufika pa +60℃, ndipo ivi vikupangiska kuti viŵe vyakwenelera pa nyengo zakupambanapambana zakusungirako nkhongono. Ŵanthu awo ŵakusanda vya mafakitale ŵakuti para ŵakupanga vinthu vinandi, mtengo wa mabatire gha sodium -ion ungaŵa pasi pa 30-40% kuluska wa mabatire gha lithium-ion.
4. Mpaka wa Kugwiriskira Ntchito: Kusunga Nkhongono na Kusuntha kwa Magesi Mapu ya nthowa yakugwiriskira ncito mabatire gha sodium-ion yikuwoneka makora comene, ndipo yikukhwaska misika yiŵiri yikuru: Nthowa Zikuru zakusungirako Nkhongono (ESS): Ici cikuwoneka kuti nchinthu cakuzirwa comene. Ŵalara ŵa ku EVE Energy ŵakulongosora kuti uwemi wa ma SIB pa mtengo wa vyakupangira na kusangika kwa vinthu vikuŵapangiska kuŵa ŵawemi pakusunga vinthu vikuruvikuru na kusunga nkhongono zakugaŵika. Magalimoto gha magesi ghakuchimbira chomene (EVs): Ivi vikusazgapo magalimoto gha magesi ghaŵiri/ghatatu, magalimoto ghachokoghachoko, na magalimoto ghakukwera ŵanthu ghakuchimbira chomene. Qingna Tech yakhazikiska mgwirizano wa nthowa na ŵalongozgi ŵa mafakitale nga ni Jinpeng Group na Lima Vehicle Industry, kusazgapo phangano la kugula 1.75 GWh / chaka na Jinpeng. Qingna "layered oxide + selo yikuru ya cylindrical" vinthu vikupereka nkhongono zakukwana 142 Wh / kg, umoyo wa mzere ukujumpha 6,000 mzere, 5C kulipira / kuseŵezeska nkhongono, na 82% nkhongono kusunga pa -40 degree. Kufikira kwa pa caru cose kukukura. Qingna Tech watuma masampulo na kufika pa mgwirizano wa batch na makampani eyiti gha ku Europe, kuŵika chomene mtima pa mapulogalamu mu msewu wakuchepa -luŵiro, nkhongono zakusungika zakukhalamo / UPS, na ndondomeko za nkhongono zakusungika za mu mizi . 5. Kuwonekera kwa munthazi: Kupambanapambana kwa tekinoloje na Industry Syring for theRENA kusunga na kuthandazgika kwa galimoto ya magesi, sodium - ion mabatire ghakuwoneka nga ni vyakukhozga chomene ndiposo vyakukhozga chilengiwa ku luso la lithiamu-ion. Munthazi muzamuwona kusiyanasiyana mu tekinoloje ya SIB. Makampani nga ni Qingna Tech ghakulondezga nthowa zakuyana waka zakupangira mabatire gha oxide, polyanion, na ghakukhozga gha sodium. Magulu gha masambiro, nga ni agho ghali ku Western University, ghakulutilira kulimbana na masuzgo ghakuru nga ni kwenda kwa ion mwakuchedwa mu mapulani ghakukhora -boma. Pakuyowoya za kapangikiro ka mafakitale, mabatire gha sodium-ion ghakukhazga yayi kuti ghazamunjira mu malo gha mabatire gha lithiamu-ion. M’malo mwake, malo ghakukhozgera ghakwenera kuti ghazamuwoneka: lithiamu - ion yingalutilira kulamulira ma EV ghakugwira ntchito makora, apo sodium- ion yikuseŵa malo ghake ghakusungirako nkhongono, ma EV ghakuchepa -, na ghaŵiri {el- w Kumalizga Na kulutilira kwa tekinoloje na kukhwima kwa unyolo wa mafakitale, mabatire gha sodium-ion ghakunjira mu nyengo ya golide ya chitukuko. Kukwera kwa munda uwu kuzamupangiska waka kuti nthowa za tekinoloje zakusungirako nkhongono ziŵe zakupambanapambana yayi, kweni kuzamuwovwiraso kucepeska suzgo pa nthowa yakupelekera mabatire gha lithiamu-ion, ndipo kuzamuŵika nkhongono ziphya mu kusintha kwa nkhongono pa caru cose.
