【摘要】：鋰硫電池由于其高能量密度(理論高達(dá)2600 Wh/kg)、低成本、環(huán)境友好等優(yōu)點(diǎn)而廣受關(guān)注.但是鋰硫電池仍存在正極活性物質(zhì)利用率低、循環(huán)性能差等問(wèn)題.造成這些問(wèn)題的主要原因是易溶于有機(jī)電解液的中間產(chǎn)物聚硫鋰Li2Sn(4≤n≤8)和不溶于有機(jī)電解液的硫化鋰造成的.簡(jiǎn)要介紹了鋰硫電池體系的主要問(wèn)題,并結(jié)合本研究小組的研究,對(duì)鋰硫電池用電解質(zhì)體系從有機(jī)電解液組成、電解液添加劑、聚合物電解質(zhì)和無(wú)機(jī)固體電解質(zhì)等方面進(jìn)行了詳細(xì)的綜述,最后對(duì)電解質(zhì)的發(fā)展前景進(jìn)行了展望.
[Abstract]:Lithium-sulfur batteries have attracted much attention due to their high energy density (theoretical value up to 2600 Wh/kg), low cost and environmental friendliness. However, lithium-sulfur batteries still have some problems, such as low utilization of positive active substances and poor cycling performance. These problems are mainly caused by polysulfide lithium Li2Sn (4 鈮，
