与插层型锂离子电池（LIB）相比，转换型锂硫（Li-S）电池因为其高理论能量密度（2600 Wh kg-1）而受到越来越多的关注。但是，多硫化物穿梭效应、缓慢的反应动力学和锂金属枝晶生长等问题阻碍了锂硫电池的进一步应用。硫正极的多步转化反应涉及电极/电解质之间一系列Li+的交换，这些反应也亟需克服脱溶剂和电荷载体扩散的能量势垒，这导致了缓慢的转化动力学以及多硫化物中间体的积累。

锂离子电池（LIBs）在低温（＜-20 ℃）下的稳定运行对于电动汽车的推广和应用至关重要。在低温下，锂离子（Li+）迁移速率降低，反应速率减慢，导致电池内阻增大，可逆容量下降，电动汽车的续航里程减少，甚至可能诱发锂枝晶生长，增加安全隐患。与石墨负极相比，金属锂负极具有更高的能量密度（3860 mAh g-1），是LIBs的理想负极材料。深入理解金属锂的微观结构和性能随温度的变化规律，是突破LIBs...
铁基超导体作为继铜氧化物超导体之后的第二类高温超导体，其超导机理是凝聚态物理研究的重要课题。绝大多数铁基超导体具有位于布里渊区中心的空穴型费米面和位于布里渊区顶角的电子型费米面。一种普遍的超导机理（费米面“嵌套”）认为，电子在电子型与空穴型费米面之间的散射，是铁基超导体中电子配对和超导电性产生的主要原因。
采用高温固相法合成Sr3B2O6：Eu3+，Li+红色荧光粉，考察了激活剂Eu3+和电荷补偿剂Li+浓度对Sr3B2O6：Eu3+，Li+荧光粉发光性能的影响。结果表明：适量掺杂Eu3+、Li+离子并不改变Sr3B2O6的结构。当Eu3+掺杂量为4%、Li+的掺杂量为8%时，在900 ℃下灼烧2 h可以得到发光性能最佳的Sr2.9B2O6：0.04Eu3+，0.08Li+红色荧光粉。以394 nm...
