Baarayaasha ka socdaJaamacadda Farsamada ee Munich(Tum) iyoJaamacada rwth AachenJarmalka ayaa isbarbar dhigay waxqabadka korantada ee batariyada sodium-ion tamarta-ion (SIBs) oo ah tamar-tamar-tamar-tamar-tamar-tamar sare (Libs) oo leh lithium-thingphate (LFP) Cathode .

Kooxda ayaa ogaatay in dacwadda iyo heerkulka ay saameyn sare ku leeyihiin iska caabbinta garaaca wadnaha iyo carqaladeynta SIBs ka badan kuwa labanlaabmayo, oo ay soo jeedinayaan in SIBs ay u baahan karaan heerkul aad u yar oo maareyn ah si loo hagaajiyo waxqabadka, gaar ahaan heerarka hoose ee ka hooseeya.

• Si loo sharxo caabbinta garaaca wadbo dheeri ah Sidaa darteed, cilmi-baaristu waxay muujineysaa in baytariyada sodium-ion ay ka badan yihiin kor ku xusan heerka iyo heerkulka ka badan baytariyada lithium-ion.

Daraasad:

"Baybalka soodhiga-ion [Sbs] waxaa guud ahaan loo arkaa inay yihiin bedelka isbadalka ee libaaxyada," ayuu saynisyahannadu sheegtey. "Si kastaba ha noqotee, kala duwanaanshaha dhaqanka korantada ee sodium iyo lithium waxay u baahan yihiin hambalyo labada xarkaha iyo cathode. In kasta oo loo adeegsado batteriyada lithium-lithing] Inta badan jaantusyada waxaa loo istcimaalaa maadaama aringe ', loogu talagalay kaarboon si adag loo arko inay yihiin waxyaabaha ugu dhiirrigelinaya ee loo yaqaan' 'SIBS'. "

Waxay sidoo kale sharxaan in shaqadooda loogu talagalay in lagu buuxiyo farqiga u dhexeeya cilmibaadhista, maadaama ay wali tahay aqoon la'aan ku saabsan dhaqanka korantada ee Sybs marka loo eego heerkulka kaladuwan ee Shanges marka loo eego heerkulka kaladuwan iyo eedeymaha (SF).

Kooxda cilmi-baarista ee la sameeyay, gaar ahaan, cabbiraadaha waxqabadka korantada ee heerkulka u dhexeeya 10 darajo c iyo cabbiraadaha korantada ee furan ee heerkulka kala duwan ee heerkulka kala-baxa ah iyo sidoo kale cabbiraadaha unugyada nus-unug ee unugyada unugga u dhigma .

"Intaa waxaa sii dheer, waxaan baarnay saameynta heerkulka iyo labadaba iska caabbinta tooska ah ee tooska ah (R DC) iyo soo-saareyaasha xiisaha leh ee Electroscopy (Geneis)," "Si loo baaro awoodda la isticmaali karo, tamarta la isticmaali karo, iyo hufnaanta tamarta ee hoos timaadda xaaladaha firfircoon, waxaan qabanay sicirka sicirka sicirka anagoo adeegsanayna heerarka xamuulka kaladuwan ee heerkulka kala duwan."

Cilmi baadhayaashu waxay cabiraan batteriga lithium-ion, batteriga-soojidka sodium-ion oo leh cathode-manganese birta-manganese ah oo leh batteriga lithium-ion leh cathode-ka LFP. Dhamaan seddexda ayaa muujisay cudurka dabaysha, taasoo la micno ah korantada wareega-furan ee ku kala duwan ee ka dhexeysa dacwadda iyo bixinta.

"Waxa liqligoodu yahay, SIBS, Harteris-ka ayaa ugu horreyn ka dhacaya casharka yar, kaas oo ah, sida ay u muuqdaan cabirrada unugyada nus-unugyada," akadeemiyaasha ayaa la adkeeyay. "R r DC iyo carqalad ku ah The LO ee The LO waxay muujinayaan ku tiirsanaanta yar ee SoC. Taa bedelkeeda, SIBs, RC DC iyo carqalad si weyn kor ugu kacaysa cashuuraha ayaa ka hooseeya 30%, halka CHASS ay leedahay saameyn ka soo horjeedda oo ay horseedaan hoos u dhigga iyo qiyamka xiisaha leh. "

Intaa waxaa dheer, waxay hubiyeen in ku tiirsanaanta heerkulka ee R_DC iyo carqaladdu ay ka sarreyso SIBs in ka badan Libaaxyada. "Imtixaannada 'LIB-yada' ma muujiyaan saameyn weyn oo ku saabsan barnaamijka Socodka ee ku saabsan waxqabadka safarka. Taas bedelkeeda, baaskiil-galka SIBS 50% ilaa 100% SOS waxay yareyn karaan khasaaraha hufnaanta in ka badan kala badh si ay u adeegsadaan si hufan ee si hufan ee sifey si aad ah u kora Kala duwanaanshaha soo-dhexaad ah marka loo eego noocyada hoose.
