In 2011, Komaba et al. [24] investigated the structural changes of commercial hard carbon during sodium insertion and confirmed that the sodium ion storage mechanism aligns with the insertion-filling model. As shown in Fig. 2 (a, b), the authors demonstrated through non-in situ XRD and Raman analysis that sodium ions are inserted into parallel carbon layers in
Ice storage air-conditioning is currently the most widespread application of cold storage PCMs worldwide. The concept of cold storage air-conditioning was first proposed globally in the 1930s (Fig. 2) Urban electricity consumption has dramatically increased with increasing economic and social development.

Ice-templating, also known as directional freezing or freeze-casting, features the tunability of microstructure, the wide applicability of functional nanomaterials,
Finally, it has been shown that energy storage will be required for adoption of significant percentages of renewable energy generation, particularly approaching the 2030 California 50% RPS. This will become increasingly important as the nation and world attempt to limit carbon emission in the coming decades.
Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) are prospective candidates for large-scale energy storage systems cause of their abundant resources. However, unsatisfactory rate and
The ICE is significantly higher than the majority of reported HCNs and the combination of superior ICE and cycle life is still at a record value among hard carbon materials.

In this paper, an investigation was carried out on using carbon dioxide as the phase change material in a thermal energy storage unit for storing energy around −55 C. A model of a pillow plate heat exchanger created in the Modelica language was used to establish a parametric study where both geometrical and operational parameters of the

Initial Coulombic efficiency (ICE) has been widely adopted in battery research as a quantifiable indicator for the lifespan, energy density and rate performance
The enormous demand of energy and depletion of fossil fuels has attracted an ample interest of scientist and researchers to develop materials with excellent electrochemical properties. Among these materials carbon based materials like carbon nanotubes (CNTs), graphene (GO and rGO), activated carbon (AC), and conducting
We summarized the recent research progress in ice-templated materials (ITM) for electrochemical energy storage and conversion, with a focus on their application in supercapacitors, Li-ion
The structural advantages of the hard carbon contribute to a high reversible sodium storage capacity of 369.8 mAh g −1 with an initial Coulombic efficiency (ICE) of 82.5% at 20 mA g −1. Furthermore, in-situ Raman spectroscopy results demonstrate that pseudo-graphitic structures, with large interlayer spacing, provide sufficient diffusion
Activated carbon mainly relies on EDLC to achieve energy conversion, which is a process that depends on the electrostatic adsorption or desorption of ions in the energy storage material. The pore structure, SSA, and surface groups are thought to significantly affect AC-based electrode performance, particularly in aqueous environments.
In contrast to activated carbons, the templated carbons represent materials with narrow range of pore size, giving better control over structure. Zeolite template carbon, with high surface area (3200 m 2 /g) and fine pore size (0.5-0.9 nm), have shown hydrogen storage capacity upto 6.9 wt.% at 77 K and 20 bar with heat of
Latent heat storage (LHS) leverages phase changes in materials like paraffins and salts for energy storage, used in heating, cooling, and power generation. It relies on the absorption and release of heat during phase change, the efficiency of which is determined by factors like storage material and temperature [ 102 ].

The carbon material offers excellent electrochemical storage performance, but it only shows a low ICE of 47.6% (Fig. 3 c). In contrast, the hard carbons synthesized by the authors in this paper with less heteroatom doping have higher ICE.
The energy storage characteristic of PCMs can also improve the contradiction between supply and demand of electricity, to enhance the stability of the power grid [9]. Traditionally, water-ice phase change is commonly used for cold energy storage, which has the advantage of high energy storage density and low price [ 10 ].
As a result, the hybrid polystyrene-based carbon achieves excellent Na storage performances, including a higher ICE of 70.2% and a larger specific charge
