“…For example, 3DOM CoFe 2 O 4 with 130 nm macropores also exhibited a large irreversible capacity loss in the fi rst cycle. [ 82 ] The EDP layer formation can result in a complex evolution of the specifi c capacity over multiple cycles, but this behavior depends on the material architecture. In mesoporous Co 3 O 4 nanocast from KIT-6 [ 41 , 54 ] or mesoporous nanowire bundles nanocast from SBA-15, [ 41 ] a large excess capacity was observed in the fi rst cycle, dropped in the second cycle, built up again over the next 20 cycles, and then gradually dropped over the following cycles ( Figure 10 A-C).…”

“…3DOM Ni prepared by electrodeposition within a polystyrene colloidal crystal template was used as both the support and current collector for a lithiated MnO 2 cathode with extremely fast rate capabilities. [ 73 ] Over the last decade, numerous other 3DOM electrodes have been synthesized by colloidal crystal templating, including those composed of the cathode materials LiMn 2 O 4 , [ 74 ] LiFePO 4 , [ 75 ] and FePO 4 , [ 76 ] and the anode materials anatase TiO 2 , [77][78][79] Li 4 Ti 5 O 12 , [ 80 , 81 ] CoFe 2 O 4 , [ 82 ] and SnO 2 . [ 83 ] In addition, a 3DOM solid electrolyte of the composition Li 1.5 Al 0.5 Ti 1.5 (PO 4 ) 3 (LATP) has been synthesized.…”

Numerous benefits of porous electrode materials for lithium ion batteries (LIBs) have been demonstrated, including examples of higher rate capabilities, better cycle lives, and sometimes greater gravimetric capacities at a given rate compared to nonporous bulk materials. These properties promise advantages of porous electrode materials for LIBs in electric and hybrid electric vehicles, portable electronic devices, and stationary electrical energy storage. This review highlights methods of synthesizing porous electrode materials by templating and template‐free methods and discusses how the structural features of porous electrodes influence their electrochemical properties. A section on electrochemical properties of porous electrodes provides examples that illustrate the influence of pore and wall architecture and interconnectivity, surface area, particle morphology, and nanocomposite formation on the utilization of the electrode materials, specific capacities, rate capabilities, and structural stability during lithiation and delithiation processes. Recent applications of porous solids as components for three‐dimensionally interpenetrating battery architectures are also described.

MnCo 2 O 4 octahedral structure with edge length about 500 nm was successfully synthesized by a simple hydrothermal route. With the use of NaOH, the chemical potential and the rate of ionic motion in the precursor solution were controlled, and the particle size was limited. The magnetization measurements revealed that the products exhibited ferrimagnetic characteristics with different saturation magnetization and coercivity at different measuring temperatures. In addition, the as-prepared MnCo 2 O 4 as anodes for lithium-ion batteries (LIBs) exhibited a reversible capacity of 1180 mA·h/g and 1090 mA·h/g at current density of 0.1 C and 1 C, respectively. The excellent cyclic performance was confirmed because the value of reversible capacity for MnCo 2 O 4 was 618 mA·h/g after 50 cycles at 0.1 C. Owing to the good rate performance, MnCo 2 O 4 octahedral products were suggested to have a promising application as anode material for LIBs.
