9月17日下午,，受材料學(xué)院邀請(qǐng),，澳大利亞臥龍崗大學(xué)郭再萍教授在5號(hào)教學(xué)樓502-1會(huì)議室為我校師生作題為“Hybrid Nanostructures as Electrode Materials for Alkali Metal-Ion Batteries”的學(xué)術(shù)報(bào)告。
郭再萍教授詳細(xì)介紹了她的研究團(tuán)隊(duì)近幾年在二次電池電極材料領(lǐng)域的一些研究進(jìn)展,。首先,，受Na2TiSiO5材料在鈉離子電池中表現(xiàn)出的優(yōu)異性能啟發(fā)，郭再萍教授團(tuán)隊(duì)成功制備出了新型電極材料Li2TiSiO5,，并將其用作鋰離子電池負(fù)極材料,，該材料具有優(yōu)異的結(jié)構(gòu)穩(wěn)定性，更低的放電電位,，能同時(shí)保證電池具有更穩(wěn)定的長(zhǎng)循環(huán)壽命和更高的放電容量,；隨后她介紹了如何利用等離子體誘導(dǎo)陽離子深層摻雜TiO2，可以有效地提高鈉離子電池負(fù)極材料的儲(chǔ)鈉性能,；除此之外,，郭再萍教授團(tuán)隊(duì)還探究了電解液鋰鹽配方對(duì)鉀離子電池電極界面的影響，以及利用液相剝離的方法制備出超薄Sb2S2納米片結(jié)構(gòu)用以提高鉀離子電池的循環(huán)穩(wěn)定性等,。報(bào)告深入淺出,，系統(tǒng)性的研究工作讓研究生們受益匪淺,。會(huì)后，郭再萍教授與參會(huì)師生就相關(guān)學(xué)術(shù)問題進(jìn)行了細(xì)致深入的討論,。
