Sweden rama Chalmers University of Technology chuan electric lirthei battery recycle dan thar a report. Hemi kawngah hian chemical man to leh hlauhawm tak tak a ngai lo a, a chhan chu zirchiangtute hian plant kingdom-a organic acid hmuh tur oxalic acid an hmang a ni.
He process hian electric vehicle battery aṭanga aluminium 100% leh lithium 98% chu a la chhuak thei niin university chuan a sawi. Hei hian raw material hlu tak tak nickel, cobalt leh manganese te pawh a hloh tlem phah bawk.
Chalmers University-a Battery Recycling Laboratory-ah chuan team pakhat chuan battery-a active material pawimawh tak takte powdery mixture, black matter chu oxalic acid-ah process an tum a. A bik takin Volvo electric car battery chungchang kan sawi a. Note-ah chuan a kalphung chu “coffee siam” tiin a sawi. Dik tak chuan engkim hi a buaithlak zawk hle a, a chhan chu oxalic acid process hian a duh ang effect a siam theih nan temperature, concentration leh duration te chiang taka thlan a ngai a ni. A chhan chu oxalic acid hi rhubarb leh spinach ang chi thlaiah hian a awm a.
“Tun thleng hian hetiang zat lithium hi oxalic acid hmanga thliar hran a, aluminum zawng zawng paih vek theihna tur dinhmun remchang hi tumahin kan la hmu thei lo. Battery zawng zawngah hian aluminium a awm vek avangin thir dang hloh lova kan paih chhuah theih a ngai a ni,” a ti. tiin university chemistry a sawi niin department-a graduate zirlai Leah Rouquette chuan a sawifiah.
Tuna hydrometallurgical process hman mek ah hian ferrous substance te chu inorganic acid ah an inthiar chhuak thin. Chumi hnuah “Impurities” aluminium leh copper te chu paih chhuakin active materials cobalt, nickel, manganese leh lithium te chu an la chhuak leh a ni.
Mahse, Swedish zirchiangtute chuan aluminium leh copper la awm tlemte pawh hian tihthianghlimna step tam tak a mamawh tih an hmuchhuak a, chutianga tihnaah chuan lithium hloh thei a ni. He method thar hmang hian zirchiangtute chuan an order chu an tidanglam a, lithium leh aluminium chu an tihtlem hmasa a ni. Hei hian battery thar siamna atana mamawh thir hlu tak takte hmanralna a tihtlem phah a ni.
A dawt leh tur chu coffee siam nen pawh tehkhin theih a ni: aluminium leh lithium chu liquid-ah a awm laiin, metal la awmte chu “solid”-ah a awm reng thung. Hetianga tih tur dang chu aluminium leh lithium thliar hran a ni. “Heng metal te hian property hrang hrang an neih avangin then hran a harsa dawn lo niin kan ngai a, kan method hi battery recycle dan thar beisei awm tak a ni a, chhui chian belh tlak tak a ni ngei ang,” tiin Rouquette chuan a sawi.
”Inorganic chemicals ai chuan alternative kan mamawh a ni. Tunlai process-a bottleneck lian ber pakhat chu aluminum ang chi residual materials te paih chhuah hi a ni. Hei hi waste management industry tana alternative thar pe thei tur leh hmasawnna tikhawtlai mek harsatna chinfelna kawngah pui thei tur thil thar a ni,” tiin department professor chuan a sawi. Martina Petranikova Mahse, he hmanrua hian zirchianna neih belh a ngai tih a sawi belh a: “He hmanraw hi tihpun theih a nih avangin kum lo awm turteah chuan industry-ah hman theih a nih kan beisei a ni,” a ti bawk.
Kum 2011 atang khan journalistic passion leh expertise nen electric lirthei siam chhuah chungchang kan cover tan a. Industry-a specialist media lar ber kan nih angin, thil thleng hrang hrangte quality sang ber, kimchang taka coverage kan pe a, he technology hmasawnna chak tak neih theihna tura central platform atan kan thawk a ni. Chanchinbu, background information, driving report, interview, video leh promotional information te a huam a ni.
