Here a series of Al-doped LiMnPO4 with controlled cation ratios based on appropriate charge compensation mechanisms are synthesized and compared. The results suggest that Al3+ can be doped into the lattice of LiMnPO4 and the preferable doping mechanism is in a scheme of Li1-xAlxMnPO4 where Al3+ occupies Li+ site with charge compensation by electronic defect. Such a charge-compensation mechanism is much different from those previously reported and needs further study.

通讯——LiMnPO4 中铝掺杂的意外电荷补偿

这里合成并比较了一系列基于适当电荷补偿机制的具有受控阳离子比例的 Al 掺杂 LiMnPO4。结果表明，Al3+ 可以掺杂到 LiMnPO4 的晶格中，优选的掺杂机制是在 Li1-xAlxMnPO4 方案中，其中 Al3+ 占据 Li+ 位，通过电子缺陷进行电荷补偿。这种电荷补偿机制与之前报道的有很大不同，需要进一步研究。
