Mphamvu zatsopano: Ubwino waukadaulo wa batire ya 220Ah sodium-ion ikugwetsa msika wa batri wa LiFePO4

Ndi kuchuluka kwamphamvu kwamphamvu kwamasiku ano, luso laukadaulo la batri lakhala chinsinsi chothandizira chitukuko chamtsogolo. Posachedwapa, batire yatsopano ya 220Ah sodium-ion yakopa chidwi chambiri mumakampani, ndipo ubwino wake umawonetsa kusokoneza msika wa batire wa LiFePO4.

Deta anamasulidwa nthawi ino zikusonyeza kuti latsopano sodium-ion batire kuposa LiFePO4 batire mu mayesero ambiri ntchito, makamaka mawu a kutentha kutentha, kutulutsa kuya ndi nkhokwe nkhokwe. Mabatire a sodium-ion akhoza kulipiritsidwa bwino m'malo otsika ngati madigiri 10 Celsius, omwe ndi madigiri 10 ozizira kuposa malire opanda malire a mabatire a LiFePO4. Kupambana kumeneku kumapangitsa mabatire a sodium-ion kugwiritsidwa ntchito kwambiri kumadera ozizira.

Chochititsa chidwi kwambiri ndi chakuti mabatire a sodium-ion amatha kutulutsa kuya kwa 0V. Izi sizimangowonjezera kugwiritsa ntchito batri, komanso zimathandizira kuwongolera moyo wa batri. Mosiyana ndi izi, kuya kwa mabatire a LiFePO4 nthawi zambiri kumayikidwa pa 2V, zomwe zikutanthauza kuti mphamvu yochepa imapezeka muzogwiritsira ntchito.

Pankhani ya nkhokwe, mabatire a sodium-ion amagwiritsa ntchito chinthu chochuluka cha sodium padziko lapansi. Nkhaniyi ili ndi nkhokwe zazikulu komanso zotsika mtengo zamigodi, motero zimatsimikizira mtengo wopangira komanso kukhazikika kwa batri. Mabatire a LiFePO4 amadalira zinthu zochepa za lithiamu ndipo amatha kukumana ndi ziwopsezo zopezeka chifukwa chakukhudzidwa ndi madera.

Pankhani ya chitetezo, mabatire a sodium-ion amawerengedwa ngati "otetezeka". Kuwunikaku kumatengera kukhazikika kwawo kwamankhwala ndi kapangidwe kawo, ndipo akuyembekezeka kupatsa ogwiritsa ntchito chitetezo chapamwamba.

Ubwino waukulu waukadaulo uwu ukuwonetsa kuti mabatire a sodium-ion samangopereka njira zosungira mphamvu zodalirika komanso zodalirika, koma kuyanjana kwawo ndi chilengedwe komanso kuwononga ndalama kumalimbikitsanso kugwiritsa ntchito kwawo magalimoto amagetsi, makina osungira mphamvu zazikulu, ndi zida zamagetsi zonyamula. . osiyanasiyana ntchito m'munda. Pamene ukadaulo wa batri wa sodium-ion ukukhwima, tili ndi chifukwa chokhulupirira kuti tsogolo lokhazikika komanso logwira ntchito lamphamvu likubwera.
