Iibhetri zesinyithi zeLithium (LMBs) zithembisa abaviwa ukugcinwa kwamandla kwisizukulwana esilandelayo ngenxa yoxinano lwamandla aphezulu kuzo zombini ubunzima kunye neziseko zevolumu. Nangona kunjalo, ii-LMB zihlala zingena kwi-lithium deposition engalawulekiyo, i-electrolyte interphase engazinzanga, kunye nokwandiswa kwevolumu, okukhokelela ngokulula ekusebenzeni kakuhle kweCoulombic, ukusebenza kakubi kweebhayisikile, kunye neengozi zokhuseleko, ezithintela izicelo zabo eziphathekayo iminyaka engaphezu kwamashumi amane.
Ezi ngxaki zinokuba mandundu ngakumbi ukuba zisebenza kubuninzi bamandla aphezulu. Apha kuxelwa ibhetri yesinyithi ye-lithium ezinzileyo enikwe amandla yi-3D porous poly-melamine-formaldehyde ( melamine foam ) (PMF)/Li composite anode.
I-PMF enenani elikhulu lamaqela e-polar (i-amine kunye ne-triazine) iyakwazi ukwenza i-homogenize i-concentration ye-Li-ion xa ezi ion zisondela kwi-anode surface kwaye ngaloo ndlela zifezekise i-uniform Li deposition.
Ngaphezu koko, i-anode ecwangcisiweyo ye-3D inokusebenza njengomgcini we-Li ukunciphisa utshintsho lwevolumu ngexesha lokuhluba kwe-Li kunye nenkqubo yokucwenga. Imilinganiselo ye-Galvanostatic ibonisa ukuba i-electrode ehlanganisiweyo ye-3D inokufikelela kwi-lithium ephezulu ye-Coulombic esebenzayo ye-94.7% kuxinano oluphezulu lwangoku lwe-10 mA cm−2 emva kwemijikelo engama-50 ene-hysteresis ephantsi kunye ne-voltage plateaus egudileyo. Xa idityaniswe ne-Li4Ti5O12, iiseli zesiqingatha zibonisa amandla omgangatho ophuculweyo kunye nempumelelo yeCoulombic, evula amathuba amahle ebhetri ephezulu yamandla.
