The present studies have proved that the most important factor which influences the performances of lithium metal anode in battery is the solid electrolyte interphase interface - film ( sei film ) on lithium anode . and how to make lithium metal anode have a sei film with favorable composition and stable configuration , or make the sei film have better stability , is the key to improve the electrochemistry performances of lithium metal anode in lithium secondary battery 已有的研究證明:影響金屬鋰負(fù)極在電池中性能的主要因素是其表面的固體電解質(zhì)中間相界面膜( sei膜)的性能;如何使鋰金屬電極表面具有組成良好、結(jié)構(gòu)穩(wěn)定的sei膜,或者使鋰電極表面sei膜能夠更好的“穩(wěn)定化” ,是提高鋰二次電池中鋰金屬負(fù)極電化學(xué)性能的關(guān)鍵。
