IBM yapanga maselo atsopano a lithiamu-ion opanda cobalt ndi faifi tambala. Kukweza mpaka 80% mu mphindi 5 kuposa 0,8 kWh / l!
Maselo atsopano a lithiamu-ion ochokera ku IBM Research lab. Amagwiritsa ntchito "zida zitatu zatsopano" ndipo batire yopangidwa kuchokera kwa iwo imatha kulipira mpaka 80 peresenti pasanathe mphindi 5. Sagwiritsa ntchito cobalt kapena faifi wamtengo wapatali, zomwe zingachepetse mtengo wa magalimoto amagetsi m'tsogolomu.
Zatsopano kuchokera ku IBM: zotsika mtengo, zabwinoko, zogwira mtima kwambiri
kale Mu 2016, opanga ma cell ndi mabatire adadya 51 peresenti ya cobalt padziko lonse lapansi.... Asayansi ena amayembekezera kuti chiwongola dzanja chowonjezeka cha magalimoto amagetsi chikhoza kukweza mtengo wachitsulo chifukwa kupezeka kwake kuli kochepa. Ndipo izi ngakhale kuti makampani ambiri akugwira ntchito kuchotsa chinthu ichi ku mabatire a lithiamu-ion.
Kukwera kwamitengo ya cobalt kukuchepetsa kutsika kwamitengo yamagalimoto amagetsi. Akhalabe pafupi ndi mulingo wapano:
> Lipoti la MIT: Magalimoto amagetsi satsika mtengo mwachangu momwe mukuganizira. Zokwera mtengo kwambiri mu 2030
pakadali pano Ma cell cathodes a IBM alibe cobalt, faifi tambala ndi zitsulo zolemera.ndipo zinthu zomwe zimagwiritsidwa ntchito mmenemo zimatha kuchotsedwa m'madzi a m'nyanja (gwero).
Monga mtengo wa batri lero ndi pafupifupi 1/3 ya mtengo wa galimoto yamagetsi., zinthu zotsika mtengo zomwe zimapanga maselo, zimakhala zotsika mtengo mtengo womaliza wa galimoto yamagetsi ndi wotsika.
> Kodi cobalt imakhala yochuluka bwanji mu batri yagalimoto yamagetsi? [TIDZAYANKHA]
Kuphatikiza apo, adagwiritsa ntchito high flash point liquid electrolyteszomwe zingakhale zofunikira pakagwa ngozi. Komanso, ma electrolyte amakono amatha kuyaka kwambiri.
IBM imati yayesa batire kuchokera ku ma cell ake opangidwa kuti azithandizira mphamvu yayikulu. Iye anakwanitsa kulipira mpaka 80 peresenti pasanathe mphindi 5... Izi zingatanthauze kuima pa siteshoni yolipirira kwa nthawi yofanana ndi yothira mafuta.
Wopangayo akulonjeza kuti maselo atsopanowa adzapanga mabatire omwe amachita bwino kuposa ma cell a lithiamu-ion apano. Mwachitsanzo, adzapereka mphamvu zoposa 10 kW pa lita imodzi ya batire (10 kW / l) ndipo amatha kufika mphamvu osalimba kuposa 0,8 kWh / l.
Poyerekeza, CATL idadzitamandira chaka chino kuti m'badwo waposachedwa wa maselo a lithiamu-ion okhala ndi cathode wolemera wa nickel wafika. 0,7 kWh / l (ndi 0,304 kWh / kg). Ndipo TeraWatt akuti adapanga ma cell olimba a electrolyte okhala ndi mphamvu zochulukirapo za 1,122 kWh / L (ndi 0,432 kWh / kg):
> TeraWatt: Tili ndi mabatire olimba a electrolyte okhala ndi mphamvu zenizeni za 0,432 kWh / kg. Ikupezeka kuyambira 2021
Kafukufuku wamaselo adachitidwa ndi IBM mogwirizana ndi Daimler, mwiniwake wa mtundu wa Mercedes-Benz.
Chithunzi choyambira: kumanzere kumanzere - mkati mwa labu yofufuzira, kumanja kumanja - ma cell poyesedwa, pansi kumanzere - chemistry ya cell yomwe imakutidwa "mapiritsi" apamwamba pamakina oyesera batire (c) IBM
Zolemba za Mkonzi www.elektrowoz.pl: 2016 Cobalt Consumption data kuchokera ku Cobalt Institute. Timawagwira mawu chifukwa m'nkhani yakuti "Kulipitsidwa Kwathunthu" kwa cobalt zinthu ndizokokomeza. Ngakhale ndizowona kuti cobalt imagwiritsidwanso ntchito popanga mafuta osakhazikika (= kupanga mafuta).
Izi zingakusangalatseni:
