Molten aluminum-doped porous silicon anodes enable high initial coulombic efficiency and stability
Aluminum-doped porous silicon was produced by a molten salt reaction. It showed accelerated lithium-ion diffusion kinetics and excellent structural stability. The pSi-Al significantly reduced the charge/ion transport resistance and first lithium capture by Al doping. It also affected the generation...

| description | Aluminum-doped porous silicon was produced by a molten salt reaction. It showed accelerated lithium-ion diffusion kinetics and excellent structural stability. The pSi-Al significantly reduced the charge/ion transport resistance and first lithium capture by Al doping. It also affected the generation of the SEI during cycling and promoted the formation of LiF. The achieved ICE was 90.57% and the initial reversible capacity was 2860 mA h g
−1
. Moreover, the reversible capacity was 1765 mA h g
−1
after 100 cycles at 1 A g
−1
, which demonstrated good electrochemical performance.
