＜正＞In order to get homogenous layered oxide Li（Co1/3Ni1/3Mn1/3）O2.as a lithium insertion positive electrode material, we applied sol-gel process using citric acid as a chelating agent. The oxide compounds were synthesized under different annealing temperature. XRD experiment revealed that the layered Li（Co1/3Ni1/3Mn1/3）O2.material can be synthesized at lower temperature of 800 ℃, and the oxidation {2. of Co, Ni, and Mn in the cathode confirmed by XPS were 3+, 2.and 4+, respectively. SEM observation shows that the synthesized materials have homogenous particle morphology and the particle size is about 2.0 nm. In spite of different calcination temperature, the charge-discharge curves of all the samples for the initial cycle are similar, and the cathode synthesized at 900 ℃ showed small irreversible capacity loss of 11.2.% and high discharge capacity of 2.2.2.Ahg-1 in the voltage range 2.9-4.6VLi/Li+.

无铅(Bi_(0.5)Na_(0.5))TiO_(3)(BNT)基弛豫铁电薄膜以其高Curie温度和大极化在介质储能中受到广泛关注,然而较低的击穿电场限制了它们的应用。选择Sr_(0.7)Bi_(0.2.TiO_(3)(SBT)作为固溶组元,通过组分调控提高薄膜击穿强度,优化储能性能。结果表明:BNT–xSBT薄膜均为单一钙钛矿结构,没有明显的第二相。随SBT含量增加,晶胞参数先增大后降低,介电常数略微下降,介电损耗保持稳定,击穿强度先上升后降低。最终,在最优组分样品BNT–0.40SBT中获得了362..2. kV/cm的高击穿强度和85.99 J/cm^(3)的高储能密度。这种优异的能量存储密度和出色的稳定性,表明样品BNT–0.40SBT是脉冲功率和电力电子应用电容器的有前途的候选者。
