Kuyambira 2022, kufunikira kwa msika wazosungirako mphamvu kwakula kwambiri chifukwa cha kusowa kwa mphamvu komanso kukwera kwamitengo yamagetsi m'maiko ambiri padziko lonse lapansi. Chifukwa cha kuchuluka kwakukulu komanso kutulutsa bwino komanso kukhazikika kwabwino,mabatire a lithiamupadziko lonse lapansi amaonedwa ngati njira yoyamba pazida zamakono zosungira mphamvu. Mu gawo latsopano lachitukuko, ndi ntchito yofunikira kwa onse ogwira nawo ntchito mumakampani opanga zojambula zamkuwa kuti apite patsogolo ndikulimbikitsanso kusintha kwazinthu ndikukweza kuti akwaniritse zofuna za msika watsopano ndikukwaniritsa chitukuko chapamwamba. Sizovuta kupeza kuti msika wamakono wa batri wa lithiamu ukuyenda bwino, kufunikira kwa kusungirako mphamvu kukukula mofulumira, chizolowezi cha kupatulira kwa batri ndi chofala, ndipo zinthu zopyapyala zamkuwa zamkuwa za lithiamu zakhala zogulitsa kunja kwa dziko lathu "zophulika".
Lithium mkuwa zojambulazo ndiye chidule chabatri ya lithiamu-ionzojambulazo zamkuwa, zomwe zimagwiritsidwa ntchito ngati zinthu za anode wosonkhanitsa mabatire a lithiamu-ion ndipo ndi gawo lofunikira la zojambulazo zamkuwa za electrolytic. Ndi mtundu wazitsulo zamkuwa zamkuwa zopangidwa ndi njira ya electrolytic yokhala ndi chithandizo chapamwamba, ndipo ndi gulu lodziwika bwino la zojambulazo zamkuwa za lithiamu. Chojambula chamkuwa cha batri cha Li-ion chikhoza kugawidwa ndi makulidwe kukhala zojambulazo zopyapyala zamkuwa (ma microns 12-18), zojambulazo zowonda kwambiri zamkuwa (ma microns 6-12) ndi zojambula zamkuwa zowonda kwambiri (ma microns 6 ndi pansi). Chifukwa cha kuchuluka kwa mphamvu zamagalimoto amagetsi atsopano, mabatire amagetsi amakonda kugwiritsa ntchito zojambula zamkuwa zowonda kwambiri komanso zowonda kwambiri.
Makamaka kwamphamvu mabatire a lithiamundi zofunika kachulukidwe mphamvu mphamvu, lithiamu mkuwa zojambulazo wakhala mmodzi wa yopambana. Poganizira kuti machitidwe ena amakhalabe osasinthika, chopepuka komanso chopepuka chojambula chamkuwa chomwe chimagwiritsidwa ntchito m'mabatire a lithiamu, ndiye kuti kuchuluka kwa mphamvu zambiri kumakwera. Monga m'katikati mwa mtsinje wa lifiyamu wamkuwa muzitsulo zamakampani, chitukuko cha mafakitale chimakhudzidwa ndi zipangizo zopangira mtsinje ndi mabatire apansi a lithiamu. Zopangira zopangira zam'mwamba monga mkuwa ndi sulfuric acid ndizinthu zambiri zomwe zimakhala ndi zokwanira koma kusinthasintha kwamitengo pafupipafupi; Mabatire a lithiamu akumunsi amakhudzidwa ndi chitukuko cha magalimoto atsopano amphamvu ndi kusungirako mphamvu. M'tsogolomu, magalimoto amagetsi atsopano amapindula ndi ndondomeko ya dziko la carbon neutral, ndipo chiwerengero cha kutchuka chikuyembekezeka kupitiriza kuwonjezeka kwambiri, ndipo kufunikira kwa mabatire a lithiamu-ion kudzakula mofulumira. Kusungirako mphamvu zamagetsi ku China kukukula mofulumira, ndipo ndi chitukuko cha mphamvu ya mphepo, photovoltaic ndi mafakitale ena, kusungirako magetsi a electrochemical ku China kudzakula mofulumira. Kuchulukirachulukira kwa kuchuluka kwa mphamvu zosungirako zamagetsi zamagetsi kukuyembekezeka kukhala 57.4% kuyambira 2021-2025.
Ndi khama logwirizana la makampani a batire ndi opanga zojambulazo zamkuwa, chojambula chamkuwa cha lithiamu cha batri cha China chili patsogolo pa dziko lapansi mwa kupepuka komanso kuonda. Pakali pano, zojambulazo zamkuwa za mabatire a lithiamu m'nyumba zimakhala ndi ma microns 6 ndi ma microns 8. Pofuna kupititsa patsogolo kachulukidwe wa mphamvu ya batri, kuwonjezera pa makulidwe, kulimba kwamphamvu, kutalika, kukana kutentha ndi kukana kwa dzimbiri ndizofunikiranso zizindikiro zaukadaulo. 6 ma microns ndi woonda mkuwa zojambulazo wakhala cholinga cha masanjidwe a opanga zoweta ambiri, ndipo pakali pano, 4 microns, 4.5 microns ndi mankhwala ena woonda agwiritsidwa ntchito m'mabizinesi mutu monga Ningde Time ndi China Innovation Aviation.
The linanena bungwe lenileni n'zovuta kufika mphamvu mwadzina, ndi wonse mphamvu magwiritsidwe mlingo wa lifiyamu mkuwa zojambulazo makampani ndi za 80%, poganizira mphamvu osayenera kuti sangathe misa opangidwa. Chojambula chamkuwa cha 6 micron kapena pansi chimakhala ndi mphamvu zogulitsirana komanso phindu lalikulu chifukwa cha zovuta kupanga. Poganizira mitengo chitsanzo cha mtengo mkuwa + processing amalipiritsa kwa lifiyamu mkuwa zojambulazo, amalipiritsa amalipiritsa 6 micron mkuwa zojambulazo ndi 5.2 miliyoni yuan/tani (kuphatikizapo msonkho), amene ali za 47% apamwamba kuposa amalipiritsa processing 8 micron mkuwa zojambulazo.
Kupindula ndi chitukuko chofulumira cha magalimoto amphamvu a China ndi mafakitale a batire a lithiamu, China ndi mtsogoleri wapadziko lonse pakupanga zojambulazo zamkuwa za lithiamu, zophimba zojambulazo zamkuwa, zojambulazo zamkuwa zowonda kwambiri komanso zojambulazo zamkuwa zowonda kwambiri. China yakhala dziko lalikulu kwambiri padziko lonse lapansi kupanga zojambula zamkuwa za lithiamu. Malinga ndi CCFA, mphamvu yaku China ya lifiyamu yamkuwa idzakhala matani 229,000 mu 2020, ndipo tikuyerekeza kuti gawo la msika waku China padziko lonse lapansi litha kukhala pafupifupi 65%.
Nordic gawo: lifiyamu mkuwa zojambulazo mtsogoleri kuyambiranso kukula, makamaka chinkhoswe mu chitukuko, kupanga ndi malonda electrolytic mkuwa zojambulazo kwa mabatire lithiamu-ion, waukulu electrolytic mkuwa zojambulazo mankhwala monga 4-6 micron kwambiri woonda lithiamu mkuwa zojambulazo, 8-10 micron kopitilira muyeso-woonda kwambiri lifiyamu mkuwa zojambulazo, 9-70 micron mkulu-ntchito zamagetsi dera zojambulazo mkuwa, 105-500 micron kopitilira muyeso-wokhuthala electrolytic mkuwa zojambulazo, etc., m'banja woyamba kukwaniritsa 4.5 micron ndi 4 micron kwambiri woonda kwambiri lifiyamu mkuwa zojambulazo mu kupanga zochuluka.
Jiayuan Technology: kwambiri chinkhoswe lifiyamu mkuwa zojambulazo, tsogolo kupanga mphamvu akupitiriza kukula, makamaka chinkhoswe mu kupanga ndi malonda a mitundu yosiyanasiyana ya mkulu-ntchito electrolytic mkuwa zojambulazo kwa mabatire lithiamu-ion ku 4.5 kuti 12μm, makamaka ntchito lithiamu-ion mabatire, komanso ochepa ntchito mu PCB. Kampaniyo yakhazikitsa maubwenzi anthawi yayitali ndi opanga mabatire akuluakulu a lithiamu-ion ndikukhala omwe amawapangira zida zawo zamkuwa za lithiamu. Kampaniyo ikuchita nawo kwambiri zojambulazo zamkuwa za lithiamu ndipo yakhala ikutsogolera pakufufuza kwazinthu ndi chitukuko, ndipo tsopano yapereka ma micron 4.5 opyapyala kwambiri a lithiamu mkuwa kwa makasitomala.
Malinga ndi ma projekiti akuluakulu amakampani amkuwa komanso kupita patsogolo kwa luso lawo lopanga, mawonekedwe azojambula zamkuwa atha kupitilira mu 2022 pakukula kwachangu, ndipo chindapusa cha zojambula zamkuwa za lithiamu chikuyembekezeka kukhala chokwera kwambiri. mlingo. 2023 iwona kusintha kwakukulu kumbali yoperekera, ndipo malondawo adzasintha pang'onopang'ono.
