“…Considering that reactions between water and the lithium electrolyte can be detrimental to the electrochemical performance, TMOxs that are used directly as energy storage materials are typically heat-treated to obtain their anhydrous form. 11 The direct application of TMOxs as energy storage materials has been investigated to a lesser extent than oxides derived from oxalates, despite the high capacities reported by several groups. [12][13][14] TMOxs behave as conversion-type materials, with the formation of metallic particles and Li 2 C 2 O 4 upon reaction with lithium.…”

“…Besides, the slight differences during the precipitation may have an effect on the crystal structure of MC 2 O 4 , MC 2 O 4 by direct precipitation tend to show a α‐monoclinic phase with the space group of C 2/c while the dihydrate MC 2 O 4 prepared during precipitation process limited in a restricted volume mainly belong to the β‐orthorhombic system in the C ccm structure . After losing crystal water at adequate temperature, the most anhydrous MC 2 O 4 (M=Fe, Co, Ni, Zn, Cu) have a monoclinic structure in the space group of P 2 1 /n except MnC 2 O 4 , in which the [M II O 6 ] octahedrons become highly distorted .

Two dimensional (2D) porous materials have great potential in electrochemical energy conversion and storage. Over the past five years, our research group has focused on Simple, Mass, Homogeneous and Repeatable Synthesis of various 2D porous materials and their applications for electrochemical energy storage especially for supercapacitors (SCs). During the experimental process, through precisely controlling the experimental parameters, such as reaction species, molar ratio of different ions, concentration, pH value of reaction solution, heating temperature, and reaction time, we have successfully achieved the control of crystal structure, composition, crystallinity, morphology, and size of these 2D porous materials including transition metal oxides (TMOs), transition metal hydroxides (TMHOs), transition metal oxalates (TMOXs), transition metal coordination complexes (TMCCs) and carbon materials, as well as their derivatives and composites. We have also named some of them with CQU‐Chen (CQU is the initialism of Chongqing University, Chen is the last name of Lingyun Chen), such as CQU‐Chen‐Co−O‐1, CQU‐Chen‐Ni−O−H‐1, CQU‐Chen‐Zn−Co−O‐1, CQU‐Chen‐Zn−Co−O‐2, CQU‐Chen‐OA−Co‐2‐1, CQU‐Chen‐Co−OA‐1, CQU‐Chen‐Ni−OA‐1, CQU‐Chen‐Gly−Co‐3‐1, CQU‐Chen‐Gly−Ni‐2‐1, CQU‐Chen‐Gly−Co−Ni‐1, etc. The introduction of 2D porous materials as electrode materials for SCs improves the energy storage performances. These materials provide a large number of active sites for ion adsorption, supply plentiful channels for fast ion transport and boost electrical conductivity and facilitate electron transportation and ion penetration. The unique 2D porous structures review is mainly devoted to the introduction of our contribution in the 2D porous nanostructured materials for SC. Finally, the further directions about the preparation of 2D porous materials and electrochemical energy conversion and storage applications are also included.

“…Fe 3 O 4 as an anode material of Li‐ion batteries (LIBs) has attracted much attention due to its high theoretical storage capacity (926 mAh/g), low cost, environment friendly and natural abundance . Unfortunately, its practical utilization suffers severe capacity degradation arising from the large volume change (ca.…”

Graphene‐doped Fe3O4 monodispersed microspheres are fabricated utilizing a droplet microfluidic technology. The electrochemical performance of the Fe3O4 microspheres as anode material for Li‐ion batteries is enhanced by doping trace graphene in the droplet reactor. The discharge capacity remains 550 mAh/g at 0.1 C after 190 cycles, which is 2 times higher than that of the graphene doped Fe3O4 samples prepared by the traditional precipitation method, and 5 times higher than that of pure Fe3O4 after 100 cycles. The uniform droplet reactor in form of a droplet microfluidic chip might provide a homogeneous microscopic condition for in‐situ electrostatic co‐assembly of the positive‐charged Fe colloids and the negative‐charged graphene oxide sheets to shape a homogeneous solid framework, resulting in homogeneously doping trace graphene into the Fe3O4 microspheres.
