Chitetezo kuwunika makampani ndi kukula kwachuma cha China, ndondomeko dziko kulimbikitsa makampani kutuluka dzuwa, ndi chitukuko cha mphamvu zatsopano, kuteteza chilengedwe, yofunika njira makampani, komanso yomanga chitetezo chikhalidwe chitetezo ndi dongosolo kulamulira.Malinga ndi "makampani achitetezo aku China" 13 Mapulani asanu a "chitukuko" akuwonetsa kuti pofika chaka cha 2020 makampani oyang'anira chitetezo ku China afika yuan yopitilira 50 biliyoni.Pakali pano, zoweta kuwunika chitetezo makampani lifiyamu batire wakhala anazindikira ndi mabizinesi ambiri m'banja mu minda okhudzana.Malinga ndi deta zogwirizana, 2015 mpaka lero, katundu okwana zoweta kuwunika chitetezo makampani lifiyamu batire ndi za 160 miliyoni, 2018 akuyembekezeka kutumiza za 160 miliyoni.Malinga ndi Foresight Industry Research Institute kupereka kutsika makampani deta zikusonyeza kuti chitetezo polojekiti makampani monga unyolo lonse makampani mu makampani kukula kwambiri, chifukwa cha makhalidwe ake makampani ndi kutsika makampani amafuna makhalidwe pali kusiyana, kotero tsogolo makampani danga. ndi chachikulu.
Monga momwe amagwiritsidwa ntchito kwambiri pamakampani owunikira chitetezo, batire ya lithiamu, ntchito zake zimaphimba mitundu yosiyanasiyana ya batri, monga mabatire achiwiri a lithiamu-ion ndi mabatire apamwamba a lithiamu-ion.Mabatire a lithiamu-ion omwe amagwiritsidwa ntchito m'makampani achitetezo nthawi zambiri amakhala olimba a electrolyte (electrolyte), ndipo ma electrolyte olimba popanga amatha kugawidwa m'mitundu iwiri yoyika mpweya wamankhwala ndi njira ya electrodialysis.Njira yopangira mpweya wamankhwala ndi njira yomwe electrolyte yolimba yokonzekera (monga silicon dioxide, lead dioxide) imasakanizidwa ndi zida zachitsulo za oxide m'malo mwa manganese oxide kapena aluminium oxide, kenako filimu yopyapyala imatengedwa ndi electrolyte. zochita monga organic anode.Ubwino waukulu ndi mtengo wotsika komanso moyo wautali wozungulira;choyipa ndikuti kugwiritsa ntchito kuyenera kusakanikirana ndikuwonjezera ma reagents othandizira (monga mapulasitiki) pazowonjezera, zomwe zimakhala zokwera mtengo;ndipo ngati palibe ma reagents owonjezera omwe amawonjezeredwa, mpweya wambiri wapoizoni (formaldehyde, carbon dioxide) udzapangidwa panthawi yogwiritsira ntchito;kuonjezerapo, sichingasinthidwenso ndipo sichingagwiritsidwe ntchito bwino.Kuchokera pakukula kwachitukuko, kugwiritsidwa ntchito kwake ngati chinthu chosungiramo mphamvu kukukulirakulira.
M'zaka zaposachedwapa, chitukuko ndi ntchitomabatire a lithiamu-ionzakhala zofala.Komabe, popeza pali mavuto ambiri ndi mabatire a lithiamu-ion, monga kusakhazikika, moyo waufupi komanso chitetezo chochepa, m'pofunika kufulumizitsa kufufuza ndi chitukuko kuti muphunzire ndi kuthetsa mavutowa.Malinga ndi zomwe zanenedweratu, pofika chaka cha 2020, magalimoto atsopano aku China akuyembekezeka kufika mayunitsi 200,000.Pakati pawo, kukula kwa msika wa mabatire a lithiamu-ion pamagalimoto anzeru kudzafikira yuan yopitilira 3.6 biliyoni.
Pakalipano, zinthu zazikulu zabwino ndi zoipa zomwe zimagwiritsidwa ntchito pa mabatire a lithiamu-ion ndi: 1. NCM622 / 623: Pansi pa mtengo wotsika mtengo, NCM522 imagwiritsidwa ntchito ngati anode, yomwe ingapeze malo apamwamba kwambiri, ndi ubwino wa kukhazikika kwa electrochemical performance, chitetezo chabwino komanso moyo wautali wozungulira;2. GaN-based: Zinthuzo zimakhala ndi thupi labwino komanso mankhwala, kuphatikizapo kukana kwa dzimbiri, mtengo wotsika, ntchito yapamwamba ndi zovuta zina kuti zigwirizane ndi Battery negative electrode ndi yoyenera kwa lithiamu ion pamene ikuwonetsa bwino chitetezo.Ndi chitukuko cha sayansi ndi teknoloji, zida zowonjezereka zowonjezereka zatuluka, monga zipangizo zamakono.Pakali pano, pali ternary monga elekitirodi zoipa Pack lifiyamu mabatire pa msika, chitetezo chake ndi kachulukidwe mphamvu ali patsogolo pa dziko, ndi mtengo wotsika, angagwiritsidwe ntchito ogula zamagetsi.Tsogolo lidzakumanabe ndi zovuta zokhudzana ndi chitetezo ndi kuwongolera khalidwe.
Kuchokera pamalingaliro aukadaulo, ndikugwiritsa ntchito kwambirimabatire a lithiamum'munda wachitetezo, bizinesi yonse ya batri ya lithiamu imadziwika ndi zotchinga zapamwamba zaukadaulo, zotchinga zazikulu zapatent komanso kutsika kwa msika.Malinga ndi zomwe mabizinesi a lithiamu-ion amalipoti apachaka akuwonetsa kuti mu 2017, kupanga ndi kugulitsa kwa batri la lithiamu-ion ku China kudaposa maola mabiliyoni a Watt.Pakati pawo, makampani 16 apakhomo a lithiamu-ion batire akutsogolera ntchitoyi;makampani akunja a lithiamu batire kuphatikiza SMC, FPC ndi NCA makampani.Mwachindunji, pali makampani asanu ndi limodzi pamsika wazinthu zotetezedwa kuposa 10%, pomwe gawo la msika la Skywing Intelligence lidafika 14.5%, CASS Technology, Lixin battery ndi Zhongying Electronics gawo la msika la 9.5%, 7.7% ndi 5.2 %, motero.
