Facile preparation of high-performance Mn and Mg co-doped FeO nanorod for lithium-ion battery anode from refined green alum slag-a "turn waste into treasure" strategy
In this work, a "turn waste into treasure" strategy is proposed to synthesize Fe 2 O 3 and use it as a lithium-ion battery (LIB) anode from green alum slag, a by-product of TiO 2 production in the industry. Through this method, a heteroatom-doped Fe 2 O 3 was obtained and showed a stable s...

| Summary: | In this work, a "turn waste into treasure" strategy is proposed to synthesize Fe
2
O
3
and use it as a lithium-ion battery (LIB) anode from green alum slag, a by-product of TiO
2
production in the industry. Through this method, a heteroatom-doped Fe
2
O
3
was obtained and showed a stable specific capacity of 1209 mA h g
−1
at 500 mA g
−1
, which was superior to pure-Fe
2
O

that was prepared in the laboratory. Besides, the full battery was assembled with Fe
2
O
3
as the anode, and the specific capacity was maintained at 102 mA h g
−1
after 100 cycles of stable cycling at 1.0 A g
−1
, showing excellent cycling and rate performance. This work offers a green low-cost and promising option for the development of LIBs anode materials and making TiO
2
industrial production more economical and environmentally friendly.
Herein, value-added Fe
2
O
3
was recovered from green alum slag, a by-product of TiO
2
production in the industry. It worked well in LIBs as anode, showed a stable specific capacity of 1209 mA h g
