Makampani aku China akuchulukirachulukira kulengeza kuti ndi opanga komanso opanga mabatire akulonjeza. Tekinoloje zakunja sizongokopedwa, koma zimakonzedwa ndikukhazikitsidwa kukhala malonda.
Kugwira ntchito bwino kwamakampani aku China kumabweretsa kupita patsogolo kosapeΕ΅eka kwa mawonekedwe a batri, ngakhale ife, ndithudi, tikufuna "chilichonse nthawi imodzi." Koma izi sizichitika, koma batire ndi osiyanasiyana makilomita oposa 800 ndipo popanda mtengo cobalt posachedwapa adzaonekera. Tikukuthokozani ku kampani yaku China ya SVOLT Energy Technology.
Posachedwapa, kasamalidwe ka SVOLT Energy, wocheperapo wakale wa Chinese automaker Great Wall Motor, mzere watsopano wopangira mabatire a lithiamu-ion olonjeza. Mzerewu udzatulutsa mitundu iwiri ya mabatire, koma pakali pano pang'onopang'ono. Kupanga kwakukulu kudzayamba mu theka lachiwiri la chaka chamawa. Kodi izi ndi zinthu zotani?
Batire yamtundu umodzi idzadalira ma cell a 115 Ah omwe ali ndi mphamvu zokwana 245 Wh/kg. Maselowa akukonzekera kuti agwiritsidwe ntchito kusonkhanitsa mabatire opangidwa mochuluka kwa magalimoto ambiri amagetsi. Chogulitsa chachiwiri, ma cell omwe ali ndi mphamvu ya 226 Ah opanda cobalt, adzapangidwa kokha kwa Great Wall Motor, yomwe ikukonzekera kuwayika pamagalimoto ake amagetsi apamwamba.
Malinga ndi wopanga, ma cell atsopano a L6 atali mu batri adzapatsa galimoto yamagetsi yofikira mpaka 880 km pamtengo umodzi. Moyo wa batri wolengezedwa umaposa zaka 15, zomwe zitha kusinthidwa kukhala ma kilomita 1,2 miliyoni popanda kusintha batire.
Kuti akwaniritse mawonekedwe a batri ochititsa chidwi, akatswiri aku China apanga ukadaulo wambiri ndi njira zaukadaulo, kuyambira ndikusintha kwa cobalt mu anode ndi faifi tambala ndi zida zina. Mwachitsanzo, ma ion a lithiamu mu batri amasinthidwa ndi ayoni a nickel, omwe amalepheretsa kuwonongeka kwa lithiamu panthawi ya batri. Izi zokha zinayambitsa mavuto aukadaulo, omwe tsopano athetsedwa bwino.
Pakhalanso zatsopano zambiri popanga ma cell a batri, komanso kukonzanso kapangidwe kake ndi kachitidwe ka batire yonse yama cell ambiri. Paketi yatsopano ya batri imapangidwa molingana ndi mfundo ya matrix ndipo imatha kusinthidwa mosavuta ku magawo omwe atchulidwa, zomwe zimachepetsanso mtengo wopangira ma batire.
Tiyeni tiwonjezere kuti mabatire a SVOLT Energy opanda cobalt amagwira ntchito pamagetsi okwera pang'ono - 4,3-4,35 V. Ndi chifukwa cha izi kuti mphamvu zawo zosungirako zosungirako zimakhala zapamwamba kuposa mabatire amtundu wa lithiamu-ion. Zikuwonekerabe momwe amachitira pochita.
