Lithium simbi mabhatiri (LMBs) ari kuvimbisa vakwikwidzi vechizvarwa chinotevera chekuchengetedza simba nekuda kwehuremu hwavo hwepamusoro pamabhesi ehuremu nemavhoriyamu. Zvisinei, maLMBs anowanzoita zvisingadzoreki lithium deposition, kusagadzikana kwakasimba kwe electrolyte interphase, uye kuwedzera kwevhoriyamu, izvo zvinotungamirira nyore nyore kuderera kweCoulombic kunyatsoshanda, kusaita zvakanaka kwebhasikoro, uye kunyange njodzi dzekuchengetedza, zvichidzivisa maitiro avo anoshanda kwemakore anopfuura makumi mana.
Matambudziko aya anogona kuwedzera kana akashandiswa pahuwandu hwemagetsi akawandisa. Pano bhatiri resimbi re lithium rakagadzikana rinogoneswa ne 3D porous poly-melamine-formaldehyde ( melamine foam ) (PMF)/Li composite anode rinotaurwa.
PMF ine nhamba huru yemapoka epolar (amine uye triazine) inogona kunyatsoita homogenize Li-ion concentration apo aya maion anoswedera kune anode pamusoro uye nokudaro anobudirira yunifomu Li deposition.
Uyezve, iyo 3D yakarongeka anode inogona kushanda seLi host kudzikamisa shanduko yevhoriyamu panguva yekubvisa Li uye plating maitiro. Zviyero zveGalvanostatic zvinoratidza kuti iyo 3D composite electrode inogona kuwana yakakwirira-lithium Coulombic kunyatsogona kwe94.7% pahupamhi huripo hwe10 mA cm−2 mushure memakumi mashanu ane low hysteresis uye inotsvedzerera voltage makomo. Kana yakabatanidzwa neLi50Ti4O5, hafu-masero anoratidza kukwidziridzwa chiyero uye kugona kweCoulombic, kuvhura mikana mikuru yemabhatiri ane simba guru.
SINOYQX yakatsigira melamine furo zvinhu zvekutsvaga uku.
Kuti uwane rumwe ruzivo nezve melamine foam kubva kuSINOYQX, ndapota svika kwatiri pa [email inodzivirirwa] kana inzwi kwatiri: +86-28-8411-1861.
