Swedish Startup Northvolt's Sodium-Ion Battery Innovation Inoderedza Europe's China Dependence.

Sekureva kweBritish "Financial Times" pamakumi maviri nerimwe, Northvolt, yekutanga yeSweden inotsigirwa nevanoisa mari vakaita seVolkswagen, BlackRock, uye Goldman Sachs, yakazivisa budiriro yakakosha mukuvandudza mabhatiri e-sodium-ion. Kufambira mberi uku kunoratidzwa senzira yekudzikisa zvakanyanya kutsamira kweEurope kuChina panguva yekuchinja kwayo kwegirinhi. Kunyangwe paine chinangwa chekukwikwidza neChina mukutsvaga nekusimudzira, Europe inoramba ichivimba nerutsigiro kubva kuChinese bhatiri indasitiri cheni. Stellantis, mugadziri wemotokari wechina pakukura pasi rose, akazivisa musi wa21 kuti mota dzayo dzemusika wekuEurope dzaizowana zvinhu zvebhatiri kubva kuChina yeContemporary Amperex Technology Co. Limited (CATL).

Chirevo chakabva kuFraunhofer Institute yekuGermany chinoti chinoda kusvika 90% yemapatent epasi rose ane chekuita nesodium bhatiri tekinoroji anobva kuChina, CATL yave kutobudirira mukugadzira mabhatiri esodium-ion. Vezvenhau veGerman vanocherekedza kuti mabhatiri parizvino anoverengera nezve 40% yemutengo wekugadzira wemotokari dzemagetsi, kunyanya mabhatiri e-lithium-ion. Mutengo wepamusoro welithium wakonzera kufarira kukuru mune dzimwe nzira. Mabhatiri eNorthvolt anosiyanisa mune yavo cathode zvinhu, izvo zviri pakati pezvakanyanya kukosha zvinodhura mumabhatiri emagetsi emotokari, kusasanganisa zvakakosha mbishi se lithium, nickel, manganese, kana cobalt.

Maererano nenyanzvi dzezvinhu paFraunhofer Institute, sodium inogona kuwanikwa kuGermany kuburikidza nenzira dzisingadhure, dzakadai kubva ku sodium chloride. Peter Carlsson, CEO uye co-muvambi weNorthvolt, akaudza "Financial Times" kuti mukana uyu unogona kusunungura Europe kubva mukuvimba neChina yehurongwa hwekugovera. Martin Osaz, nyanzvi yeGerman mune simba rekushandisa makemikari zvinhu, anoti mafambiro ematengo emangwana ezvikamu zvakakosha mumabhatiri e-lithium-ion anozokanganisa mutengo mukana we sodium.

Sezvakataurwa neGermany Battery News pa21st, Northvolt yakasimudza tariro pakati pemabhizimisi akawanda eEurope. Kubva 2017, kambani yakakwidza mari inopfuura mabhiriyoni mapfumbamwe emadhora mukuenzanisa uye mari yechikwereti uye yakachengetedza maodha anodarika mabhiriyoni makumi mashanu neshanu emadhora kubva kune vatengi vakaita seVolkswagen, BMW, Scania, neVolvo.

Yu Qingjiao, Secretary-General weZhongguancun New Battery Technology Innovation Alliance, akaudza vatori venhau ve "Global Times" musi wa22 kuti tsvakiridzo yepasi rose pamabhatiri echizvarwa chinotevera inonyanya kutarisisa nzira mbiri: sodium-ion uye solid-state mabhatiri. Iyo yekupedzisira inowira pasi peboka re lithium-ion mabhatiri, anosiyana chete mumhando ye electrolyte. Anofanotaura kuti mabhatiri e-lithium aripo acharamba ari musika wemakore gumi anotevera, nemabhatiri e-sodium-ion anotarisirwa kuve akasimba anoenderana ne lithium-ion bhatiri musika application.

Yu Qingjiao akaongorora kuti sevashandi vakakosha vekutengeserana, China neEuropean Union vane kumwe kuwirirana muchimiro chavo chekutengesa zvinhu. Kusvikira mota nyowani yeEurope uye indasitiri yemabhatiri yanyatsokura, icharamba iri nzvimbo yekutanga yekutumira kunze uye mhiri kwemakungwa dhizaini yeChina bhatiri indasitiri.
