CATL inoshamisa. Akaunza Na-ion (sodium-ion) maseru uye bhatiri rakavakirwa pazviri
CATL yeChina inozvirumbidza chizvarwa chekutanga chesodium-ion maseru uye prototype bhatiri inomhanya pavari. Kwemakore akati wandei, nzvimbo dzakasiyana dzekutsvagisa dzakaendesa mavhezheni ekutanga emaseru, uye CATL inoda kuvhura ketani yekugovera yekugadzira kwavo panosvika 2023. Naizvozvo, anotarisira kuvagadzirira kugadzirwa kwakawanda uye kuvaunza kumusika.
Lithium-ion uye Na-ion masero (Na+) muCATL vhezheni
Sodium-ion masero - zviri pachena - panzvimbo ye lithiamu, vanoshandisa imwe nhengo yeboka re alkaline, sodium (Na). Sodium ndechimwe chezvinhu zvakawandisa mupasi pevhu, inowanikwawo mumvura yegungwa uye iri nyore kuwana pane lithium. Naizvozvo, masero eNa-ion akachipa kugadzira., kana zvasvika kune mbishi.
Asi sodium inewo zvayakaipira. Zvinoenderana neshoko reCATL, chaiyo simba remasodium-ion masero anosvika 0,16 kWh/kg saka, inenge hafu yeakanakisa lithium-ion masero. Pamusoro pezvo, kushandiswa kwesodium kunoreva kuti "zvakawanda zvinoomesesa zvinodiwa" zvinofanirwa kushanda kune chimiro uye maitiro emaseru. Izvi zvinokonzerwa nekukura kwemaioni esodium, ayo akakura ne1/3 pane lithium ions uye nokudaro anosundidzira anode zvakanyanya nepakati - kudzivirira kukanganisa kune anode, CATL yakagadzira porous "hard carbon" anode.
Chizvarwa chitsva cheNa-ion masero CATL simba density inotarisirwa kusvika 0,2 kWh/kg kana kupfuura, vanozotanga kutsika zvitsitsinho zve lithium iron phosphate (LiFePO4) Atova masero e-sodium-ion vanochaja kusvika ku80 muzana mumaminetsi gumi nemashanuinova mhedzisiro yakanakisa - yakanakisa inotengeswa inotengeswa lithium-ion masero ari pamwero wemaminitsi gumi nemasere, uye mumarabhoritari zvaikwanisika kuderedza kukosha uku.
Iyo tekinoroji yekugadzira yeNa-ion masero inofanirwa kuenderana nehunyanzvi inozivikanwa ne lithium-ion masero.Saka, mitsetse yekugadzira inogona kushandurwa kubva sodium kuenda ku lithium, inonyora CATL. Izvo zvinhu zvitsva zvinofanirwawo kuve nekuita zvirinani pane yakaderera uye inochinja tembiricha, pa -20 madhigirii celsius vanofanira kuchengetedza 90 muzana(!) yekwavo yepakutangaZvichakadaro, mabhatiri eLFP pasi pemamiriro aya anongove ne30 muzana yekugona kwavo kana akaedzwa pakamuri tembiricha.
CATL yakaunza bhatiri rakavakirwa pamaseru eNa-ion uye haisanganisire kuti ichaunza mahybrid mhinduro kumusika mune ramangwana. Iko kusanganiswa kweLi-Ion neNa-Ion masero mune imwe imba inokubvumira kuti utore mukana wezvese mhinduro, zvichienderana nemamiriro aripo.
Chinyorwa chekunyora www.elektrowoz.pl: Yekutanga prototype yeNa-ion maseru akavharwa mumakesi ekutengesa 18650 yakaratidzwa neFrench Committee yeAtomic Energy uye Alternative Energy Sources CEA muna 2015 (mabviro). Vaive nehukuru hwesimba hwe0,09 kWh/kg.
