Ofufuzawo OchokeraKatswiri University of Munich(Tum) ndiRwth Aachen UniversityKu Germany tayerekezera magwiridwe apadera a sodium-ion (sibs) ku batire lamphamvu wa lithium-rithium-ion ndi lifiti) ndi phosadate .

Gulu lomwe lili ndi kutentha ndi kutentha kumapangitsa kwambiri pazakunja kwa nibs kuposa mabulosi, omwe angapangitse kuti mabizinesi asintha magwiridwe, 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 lifiyamu amafunikira madabwa aomwe onse ndi cakatode. Ngakhale mabatire a lithiamu-a lithiachiamu (nthawi zambiri] amakonda kugwiritsidwa ntchito ngati mawonekedwe a sode, chifukwa sibs hard carbon pompano ndi zinthu zodalirika kwambiri kwa anyub. "

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 magetsi otseguka a cell yam'manja mosiyanasiyana .

"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 kuponderezana kwa libyi kuwonetsa kudalira pang'ono pa Soc. Mosiyana ndi izi, kwa aibs, r DC ndi kusokoneza kwambiri kuchuluka kwa ma cell 30%, pomwe magulu apamwamba ali ndi vuto lotsika ndi kutsika. "

Kuphatikiza apo, adazindikira kuti kutengera kutentha kwa r_dc ndikusowa ndikokwera kwambiri kwa a rib kuposa mabisi. "Mayeso a Lib samawonetsa kwambiri Soc paulendo wozungulira. Mosiyana ndi zimenezo, kusefukira kwamitundu ya 50% mpaka 100% kumatha kuchepetsa kuchepa kwamphamvu poyerekeza ndi theka kuchokera pa 0% mpaka 50%, "adalongosolanso kuti kuchuluka kwa nib kuchuluka kwa malo ochulukirapo kuyerekeza ndi malo osiyanasiyana.
