Vuba aha, ikigo cya mbere cy’amashanyarazi cyo mu Bushinwa gifite ubushobozi bwo kubika ingufu za bateri ya sodium-ion - Volin sodium-ion bateri yatangiye gukora i Nanning, Guangxi. Iyi ni gahunda y’ingenzi y’ubushakashatsi n’iterambere ry’igihugu “ikoranabuhanga ryo kubika ingufu za bateri ya sodium-ion mu masaha 100” ry’umushinga w’icyiciro cya mbere cy’umushinga, ufite ingano ya megawati 2.5/megawati 10.
Iyi sitasiyo y'amashanyarazi ishorwamo imari kandi yubakwa na Guangxi Power Grid Company yo muri Southern Power Grid, kandi ingano y'iki cyiciro ni 10 MWh. Ingano yose y'umushinga izagera kuri 100 MWh, ishobora gutanga dogere miliyoni 73 z'amashanyarazi asukuye buri mwaka. Isosiyete y'amashanyarazi ishorwamo imari kandi yubakwa na Guangxi Power Grid Company yo muri Southern Power Grid, naho ingano y'iki cyiciro ni 10 MWh. Ingano yose y'umushinga izagera kuri 100 MWh, ishobora gutanga dogere miliyoni 73 z'amashanyarazi asukuye buri mwaka, bityo bikagabanya imyuka ihumanya ikirere ya dioxyde de carbone ho toni 50.000, kandi igahaza amashanyarazi abakoresha 35.000 mu ngo zabo.
Ugereranyije n’ububiko bw’ingufu za bateri ya lithiamu-ion, ububiko bw’ingufu za bateri ya “brothers” bushobora kubika ibikoresho fatizo, byoroshye gukurura, buhendutse, imikorere myiza mu bushyuhe buke, mu bubiko bunini bw’ingufu bufite ibyiza bigaragara. “Ububiko bw’ingufu za bateri ya sodium-ion mu rwego rw’iterambere, ikiguzi cy’ikiguzi gishobora kugabanukaho 20% kugeza kuri 30%, hashingiwe ku kunoza imiterere n’imikorere ya bateri, kunoza umuvuduko w’ikoreshwa ry’ibikoresho n’ubuzima bw’uruziga, ikiguzi cy’amashanyarazi gishobora gusuzumwa kikagera kuri 0.2 yuan / kWh, ni uguteza imbere ikoreshwa ry’ubukungu ry’uburyo bushya bwo kubika bw’icyerekezo cy’ingenzi cy’ikoranabuhanga,” ibi byavuzwe n’ikigo cy’igihugu gishinzwe kubika ingufu z’amashanyarazi, Chen Man, umunyamabanga mukuru wungirije wa Komite y’Igihugu ishinzwe Tekiniki yo kubika ingufu z’amashanyarazi akaba n’impuguke mu bya tekiniki ku rwego rw’ingamba za Southern Power Grid.
Nubwo akazi k’Ubushinwa mu bushakashatsi no guteza imbere, gukora, gushyira mu bikorwa amabwiriza agenga imiterere y’amashanyarazi, guteza imbere isoko no gukoresha bateri ya sodium-ion kari mu nzira nziza, nta rugero mpuzamahanga rw’uko ikoranabuhanga rya bateri ya sodium-ion rikoreshwa mu kubika ingufu mu bigo binini by’amashanyarazi.
Mu Gushyingo 2022, Guangxi Power Grid Company, ku bufatanye na South Grid Energy Storage Company, Ikigo cya Fiziki cy’Ishuri Rikuru ry’Ubumenyi ry’Abashinwa, Zhongkehai Sodium Technology Co., Ltd. n’izindi nzego z’itsinda ry’umushinga, batangije ku mugaragaro umushinga w’ingenzi w’ubushakashatsi n’iterambere ry’igihugu, ingingo ntoya igira iti “ikoranabuhanga ryo guhuza bateri ya sodium-ion amasaha 100 n’iyerekanwa ry’ikoreshwa ry’ikoranabuhanga.” Gukemura iki kibazo. “Twibanda ku gutegura amashanyarazi mu buryo bwo hejuru, guhuza sisitemu no gukumira no kugenzura umutekano hamwe n’izindi koranabuhanga z’ingenzi zo gukora ubushakashatsi, bwakozwe bushingiye ku burenganzira bw’umutungo bwite mu by’ubwenge bwo gutegura bateri ya sodium-ion n’ikoranabuhanga ryo guhuza sisitemu,” umuyobozi w’umushinga, South China Grid Guangxi Grid Company, umuyobozi wungirije w’Ishami ry’Udushya Gao Lik yatangije.
Bateri ifite ubushobozi bwo hejuru ni yo shingiro ry’uburyo bwose bwo kubika ingufu za bateri ya sodium-ion. Nyuma y’umwaka umwe n’igice w’ubushakashatsi, itsinda ry’umushinga ryakoze bateri ya mbere ku isi ishobora kumara igihe kirekire, ifite ubushyuhe bwinshi, ifite umutekano mwinshi wa 210Ah. “Mu rwego rw’imikorere, ubwoko bwa bateri ya sodium-ion yacu bufite ibyiza byo gukora ahantu hanini hashyuha, gusharija vuba no kuba nyinshi, kandi ishobora gusharija kugeza kuri 90% mu minota 12,” ibi byavuzwe na Hu Yongsheng, umushakashatsi mu Ishuri Rikuru ry’Ubumenyi ry’Abashinwa.
Nk’abitabiriye tekiniki b’ingenzi muri uyu mushinga, Ikigo cy’Ubushakashatsi ku Kubika Ingufu cya SouthGrid Energy Storage Company mu guhuza no gukumira no kugenzura umutekano wa bateri ya lithium, gifite uburambe bwinshi mu bushakashatsi, gikora gahunda y’igihugu y’ubushakashatsi n’iterambere “ikoreshwa ry’ikoranabuhanga mu kubungabunga ingufu za bateri ya lithium-ion”. Li Yongqi, impuguke mu bya tekiniki muri SouthGrid Energy Storage Company, yagize ati: “Nubwo amahame y’uburyo bateri za sodium na lithium ateye asa, guteza imbere uburyo bwuzuye bwo kubika ingufu buhuza imiterere yo gusharija no gusohora umuriro wa bateri za sodium bisaba guhangana n’ibibazo byinshi bishya.”
Dufashe urugero rwo guhuza sisitemu, itsinda ry’umushinga rikoresha uburyo bushya bwo kubika ingufu bushingiye ku muvuduko mwinshi wa bateri za sodium-ion, kandi sisitemu yose ihuza bateri 88 zihindura modular, bigatuma "uburyo bumwe buhuza" na bateri, mu gihe imiterere gakondo ya sisitemu yo kubika ingufu za lithium-ion ikeneye gusa guhuza bateri zirenga 40. Intego yihuse yo kongera umubare w’abahindura ingufu ni ukongera ubushobozi bwo kubona no guhindura ingufu. Uburyo rusange bwo guhindura ingufu bwa sisitemu yo kubika ingufu za bateri za sodium buri hejuru ya 92%, mu gihe bateri za lithium muri rusange ziri munsi ya 90%, byitezwe ko zizahuza kandi zisimbura bateri za lithium neza, kandi zigakoreshwa mu kubika ingufu za elegitoroniki, imodoka zikoresha amashanyarazi, imashini z’ubwubatsi n’ahandi.
Ku bijyanye no gukumira no kugenzura umutekano, itsinda ryashyizeho ingamba zo gucunga ubushyuhe bw'uburyo bukonjesha amazi ndetse n'ikoranabuhanga ryuzuye ryo gukumira no kugenzura inkongi y'umuriro ry'uburyo bwo kubika ingufu za bateri ya sodium-ion, nko kuzimya umuriro mu buryo bwa module no kuzimya umuriro mu buryo bunoze.
Itandukaniro ry'ubushyuhe riri hagati y'uturemangingo turenga 22.000 twa bateri ya sodiyumu mu buryo bwose rigenzurwa muri dogere selisiyusi 3. Gukoresha uburyo bwo gukwirakwiza ubushyuhe n'uburyo bwo gushyuha bigabanya ubushyuhe.igitambaro cy'ikirahure cya airgelnk'igikoresho cy'ubushyuhe kiri hagati y'inkingi y'amashanyarazi, igihe cyo gukwirakwiza ubushyuhe cya monomer ya batiri kiva ku minota 30 kugeza ku masaha 2, cyongereweho kugeza ku nshuro 4, binongera cyane umutekano wa module ya batiri.
Itsinda ryakoze ikoranabuhanga ryo kuzimya umuriro, gukonjesha, kurwanya umuriro, rishobora kuzimya umuriro wa bateri mu masegonda 5, kugira ngo rikore amasaha 24 ritazongera gushya cyangwa guturika. LiYongQi yagize ati: “Ikoranabuhanga ririho ubu ryo kubika ingufu za lithium na sodium kugira ngo riteze imbere kunoza imiterere y’ingufu za buri wese, ubu bushakashatsi bw’uburyo bwo kubika ingufu za bateri ya sodium-ion n’ikoranabuhanga rifatika ryo kuzimya umuriro, gukonjesha, kurwanya umuriro binyuze mu buryo bwo kubika ingufu za bateri ya lithium-ion, uburyo bwo guhindura ikoranabuhanga mu buryo bw’umutekano muri litium, uburyo bwo guhuza ingufu za sodium ku nshuro ya mbere mu buryo bw’ubuhanga.”
Ku ya 28 Mutarama 2024, n'umuhanga mu by'ubwubatsi mu Ishuri Rikuru ry'Ubushinwa Jiang Jianchun, Ishuri Rikuru ry'Ubumenyi mu Bushinwa, umuhanga mu by'ubwubatsi mu bya Cheng Shijie, umuhanga mu by'ubwubatsi mu by'ubwubatsi mu by'Uburayi, umuhanga mu by'ubwubatsi mu by'Ubushinwa Sun Jinhua n'izindi mpuguke zo mu Ishyirahamwe ry'Inganda z'Imashini ku byavuye mu mushinga wo gusuzuma isuzuma: ikoranabuhanga rusange rya "10 MWh sodium ion energy system for energy stores" ryakozwe n'itsinda ry'umushinga riri ku rwego mpuzamahanga.
