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.

Abstract. Ordered mesoporous carbons (C-1 and C-2) with tailored pore size and defined crystal orientation are prepared by liquid crystal template carbonization method using AR-mesophase pitch as carbon precursors and SBA-15 as template. The topography, pore/crystalline structure are extensively characterized via high-resolution transmission electron microscope (HR-TEM), N 2 adsorption/desorption and powder X-ray diffraction (XRD). The electrochemical properties of C-1 and C-2 as anode materials for lithium ion batteries (LIBs) are examined by galvano-statically charge/discharge and electrochemical impedance spectroscopy (EIS). Materials characterization shows that the carbons prepared in this work replicate the ordered mesoporous structure of the SBA-15 and possess tailored crystalline structure with graphene layers perpendicular to the axial of pore walls. The carbons both display preferable anode performance for LIBs. However, C-2 with thicker pore wall exhibits better properties than C-1 with larger pore size. Possible reasons for different properties are the influence of the pore structure and wall thickness of as-prepared mesoporous carbons.

Carbon microcapsules containing silicon nanoparticles (Si NPs)-carbon nanotubes (CNTs) nanocomposite (Si-CNT@C) have been fabricated by a two step polymerization method. Silicon nanoparticles-carbon nanotubes (Si-CNT) nanohybrids were prepared with a wet-type beadsmill method. A polymer, which is easily removable by a thermal treatment (intermediate polymer) was polymerized on the outer surfaces of Si-CNT nanocomposites. Subsequently, another polymer, which can be carbonized by thermal heating (carbon precursor polymer) was incorporated onto the surfaces of pre-existing polymer layer. In this way, polymer precursor spheres containing Si-CNT nanohybrids were produced using a two step polymerization. The intermediate polymer must disappear during carbonization resulting in the formation of an internal free space. The carbon precursor polymer should transform to carbon shell to encapsulate remaining Si-CNT nanocomposites. Therefore, hollow carbon microcapsules containing Si-CNT nanocomposites could be obtained (Si-CNT@C). The successful fabrication was confirmed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). These final materials were employed for anode performance improvement in lithium ion battery. The cyclic performances of these Si-CNT@C microcapsules were measured with a lithium battery half cell tests.
