通过150℃水热反应48 h成功制备了Li2MnSiO4/C纳米复合材料，然后在650℃柠檬酸存在下进行退火。有趣的是，水热合成的li2mnsio4呈梭状，由平均尺寸为50-100 nm的初级颗粒组成。碳包覆后，这些纳米颗粒与次级颗粒分离，碳层厚度约为2-4 nm。Li2MnSiO4/C纳米复合材料提供了改进的高电子导电性和增强的电化学行为。
The Li2MnSiO4/C nanocomposite is successfully synthesized by hydrothermal reaction at 150 °C for 48 h and then annealed at 650 °C in the presence of citric acid. Interestingly, the hydrothermal synthesized Li2MnSiO4shows a shuttle-like shape, which is composed of primary particles with average size of 50–100 nm. After carbon coating, these nanoparticles are separated from the secondary particles, and the thickness of carbon layer is about 2–4 nm. The Li2MnSiO4/C nanocomposite delivers an improved high electronic conductivity and an enhanced electrochemical behavior.
