橄榄石型LiMnPO4正极材料的改性及储能性能的研究

被引量 : 6次 | 上传用户：mysky_588

【摘要】

：

橄榄石型结构的Li MPO_4(M=Fe、Mn、Ni、Co)因其成本低、环境友好和结构稳定等优点被认为是最有潜力的正极材料,且其家族中的LiFePO_4已经商业化。现在,具有高对锂电势(4.1 V)和高理论能量密度(697 Wh/kg)的Li MnPO_4被认为是下一代锂离子电池正极材料。但LiMnPO_4有其自身的缺陷如电子导电率和锂离子扩散系数都较低、Mn3+的Jahn-Teller效应等,这

亚麻核不育组织化学与相关基因的表达研究

本研究采用常规石蜡切片方法和原位杂交技术,以雄性可育株和雄性不育株亚麻为材料,通过不育株花药与可育株花药切片比较,阐明雄性不育亚麻花粉败育主要时期及花药发育过程的细胞学特点。结果表明：亚麻雄性不育花药和花粉在四分体时期开始发育异常,败育过程大体划分为四个阶段：初期在四分体期绒毡层与中层分离：中期小孢子形成时期发育停滞；后期绒毡层与小孢子粘连后逐渐消失；终期花药干瘪,花粉败育。此研究基础上利用组织原
