The mesoporous Li2FeSiO4@ordered mesoporous carbon (CMK-3) has been firstly synthesized by a sol–gel method. The structural properties of the samples are characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy and nitrogen adsorption–desorption. The composite is then evaluated as a cathode material for lithium ion batteries. It exhibits greatly...
Nitrogen-doped porous graphitic carbons (NPGCs) with controlled structures were synthesized using cheap nano-CaCO 3 as template, melamine-formaldehyde resin as carbon precursor, and dilute HCl as template removing agent. In addition to its use as a template, the nano-CaCO 3 acted as an internal activating agent to produce micro- and mesopores, as an adsorbent to remove the released...
