derived by atomic layer deposition (ALD) is used to coat the 5 V LiNiMnO cathode material powders, which dramatically increases the capacity retention of LiNiMnO. It is believed that the amorphous FePO layer could act as a lithium-ions reservoir and electrochemically active buffer layer during the charge/discharge cycling, helping achieve high capacities in LiNiMnO, especially at high current densities.
通过原子层沉积(ALD)获得的(物质)用于包覆5V 锂镍锰氧化物正极材料粉末,这极大地提高了锂镍锰氧化物的容量保持率。据信,非晶态磷酸铁层在充放电循环过程中可作为锂离子储存库和电化学活性缓冲层,有助于在锂镍锰氧化物中实现高容量,尤其是在高电流密度下。
