Ofufuzawo OchokeraKatswiri University of Munich(Tum) ndiRwth Aachen UniversityKu Germany tayerekeza magwiridwe opanga mabala ambiri a sodium-enner (sibs) ku batire lapamwamba la likulu la likulu la likulu-rithialium (ma libs) ndi lithiamu-phosode (lfp).

Gulu lomwe lili ndi kutentha komanso kutentha kumakhala ndi mphamvu kwambiri pazachikumbutso ndi ma rib, omwe angapangitse kuti azigwiritsa ntchito motentha komanso amafunikira kuti azichita magwiridwe antchito, makamaka pamlingo wotsika.

• Kuti mufotokozere zakumwa zolimba: Mawuwa amatanthauza kuchuluka kwa magetsi a batte atatsala pang'ono kugwiritsidwa ntchito mwadzidzidzi. Chifukwa chake, kafukufukuyu akuwonetsa kuti mabatire a sodium-ion amakhudzidwa kwambiri ndi kuchuluka ndi kutentha kuposa mabatire a lithiamu.

Kufufuza:

Asayansi a Sodium amadziwika kuti anali kugwetsa m'malo akuti, "Asayansi adanenetsa. "Komabe, kusiyana kwa ma electrochemical machitidwe a sodium ndi lithiamu amafunikira madabwa aomwe onse ndi castrade graphite amagwiritsidwa ntchito ngati chinthu chodalirika kwambiri."

Anafotokozanso kuti ntchito yawo idapangidwa kuti akwaniritse kusiyana, chifukwa pamakhalabe chidziwitso cha zamagetsi zamitundu yamagetsi malinga ndi kutentha kosiyanasiyana ndi miyambo ya boma.

Gulu lofufuza lidachitika, makamaka, miyeso yamagetsi yamagetsi yotentha kuyambira madigiri 10 C mpaka 45 madioni otseguka a cell yam'manja mosiyanasiyana komanso maselo theka

"Kuphatikiza apo, timafufuza chisonkhezero cha kutentha ndi Soc) kuwongolera kwakanthawi (R DC) ndi Galvanostatic electrocopy speproscopy (geis)," zidafotokoza. "Pofuna kupenda kuthekera, mphamvu zambiri, komanso mphamvu yogwira ntchito pogwiritsa ntchito mphamvu zamphamvu, timayesetsa kuyeserera pogwiritsa ntchito katundu wosiyanasiyana."

Ofufuzawo adayesa betri ya lithiamu-ion ndi batiri la ion wokhala ndi chibwano cha Nickel, ndi cavin cancial, ndi batiri la lirium-ion ndi LFP Cast. Onse atatu adawonetsa magetsi Hysteresis, kutanthauza mphamvu zawo zotseguka zimasiyana pakati pa mbiya ndikuzimitsa.

"Mokondweretsa, kwa ales, hysteresis makamaka amapezeka pamiyeso yotsika, yomwe ndi, malinga ndi miyeso ya theka la theka, mwina chifukwa cha kaboni harbon Aode," Maphunziro adagogomezera. "DC DC ndi kulowerera kwa libyikirana pang'ono pa Soc. Mosiyana ndi izi, kwa ma hib, pomwe malo apamwamba amakhala ndi vuto lotsika."

Kuphatikiza apo, adazindikira kuti kutengera kutentha kwa r_dc ndikusowa ndikokwera kwambiri kwa a rib kuposa mabisi. "Mayeso a Lib sawonetsa mphamvu ya So Sound of Sour-Sourter Proviedy. Mosiyana ndi zingwe zochokera ku 50%," adalongosola kuti azoyenda bwino ma cell apamwamba poyerekeza ndi malo osiyanasiyana.
