Facile synthesis of porous LiMn 2 O 4 nano-cubes for ultra-stable lithium-ion battery cathodes

LiMn 2 O 4 (LMO) nano-cubes with a porous structure were synthesized by a template-engaged reaction using pre-synthesized Mn 2 O 3 porous nano-cubes as a self-sacrificing template. As a lithium-ion battery cathode material, LiMn 2 O 4 nano-cubes with porous structure can effectively shorten the Li + transport paths, which makes the LiMn 2 O 4 material realize excellent Li + extraction and insertion performance; the discharge specific capacity was 95.39 mA h g −1 with a capacity retention rate of 90.91% after 500 cycles of stabilization at a current density of 100 mA g −1 . This work provides a reliable synthetic route for the synthesis of LiMn 2 O 4 materials, which can be used as a potential solution for lithium manganate synthesis.
