■  锂离子电池领域新应用

锂离子电池由于具有能量密度高、寿命长、充电快、安全可靠、绿色环保等诸多优异性能，与当今人民的日常生活已密不可分，在手机、电脑、电动车、电动汽车、航空航天等领域均有广泛的应用。其中，Li₂FeSiO₄作为新一代锂离子电池阴极材料，由于具有价格低廉、环境友好、安全性好等优势，在大型动力锂离子电池应用方面具有良好的前景。然而，Li₂FeSiO₄材料在不同温度具有不同的结构相（∼ 400 °C :Pmn21,  ∼ 700 °C ：P121/n1, and ∼ 900 °C :Pmnb），因此，研究其不同结构的电化学性质对于进一步对其进行改性研究尤为重要。

Waldemar Hergetta等人^[1]采用高压光学浮区法获得了高温相（Pmnb）Li₂FeSiO₄单晶，并研究了晶体生长工艺参数对杂相的影响，相关结果已发表在Journal of Crystal Growth。作者所采用的高压光学浮区炉为德国SciDre公司的HKZ高压光学浮区法单晶炉。
