Special Issue Information

Dear Colleagues,

The excessive depletion consumption of fossil fuel, as well as the consequent environmental problems, have grown increasely serious. It is necessary and urgent to develop renewable energy resources to cut down the utilization of fossil fuel and keep the environment clean. However, most renewable energy resources are intermittently and disproportionately supplied. Consequently, electrochemical energy storage devices are used as an effective means to address the above problems. Lithium-ion batteries have been commercialized since the 1990s; however, their limited reserves cannot meet the increasing demand. The development of high-energy-density lithium-ion batteries or post-lithium-ion batteries is extremely meaningful for social progress.

First, the battery energy density is equal to specific capacity timing voltage, which is closely related with electrode materials, including cathode and anode materials. The optimization of electrode materials is necessary to obtain a high working voltage for cathodes and low working voltage for anodes, as well as a high specific capacity for cathodes and anodes. The electrochemical performance optimization usually involves the modification of the material structure and the control of morphology to achieve a reversible charge–discharge capacity and fast ion diffusion kinetics as well as the modification of the separator to control the ion shuttle and improve the active material utilization.

Second, from the perspective of practical application, the introduction of an all-solid-state electrolyte can prevent the combustion in conventional liquid electrolyte and inhibit the growth of dendrite to improve the battery safety. For metal-based batteries, the protection of the metal anode is also crucial to inhibit dendrite growth. A lot of effort has been made to explore how to improve high-energy-density and high-safety batteries, including alkali–metal–ion batteries, aqueous batteries, multivalent batteries, metal–air batteries, and liqiud-flow batteries. Additionally, the high-energy-density and high-safety batteries are expected to be industrialized in the near future.

Therefore, the purpose of this research topic is to better understand various high-energy-density batteries and relevant electrochemical behaviors (including both cathode and anode materials, metal-based anode protection, all-solid-state electrolyte and separator modification). Intensive research into these potential battery systems contributes to expanding our comprehensive understanding and practical application of high-energy-density batteries at various scales and application scenarios.

We welcome authors to submit Original Research papers, Perspectives, Reviews, Minireviews, and Short Communications on the following topics and areas:

  • The synthesis methods and advanced characterizations of cathode and anode materials
  • The fundamental investigations of the mechanism related to high-energy-density electrode materials.
  • Metal anode protection and all-solid-state electrolyte-related studies.
  • Theoretical work on the design for the advanced electrolytes and electrode materials.
  • Newly developed multivalent ion batteries, such as Zn batteries, Ca batteries, Fe batteries, Mg batteries, and Al batteries.

Polyurethane foam (PUF) is actively used for thermal insulation. The main characteristic of thermal insulation is effective thermal conductivity. We studied the effective thermal conductivity of six samples of PUF with different types and sizes of cells. In the course of the research, heat was supplied to the foam using an induction heater in three different positions: above, below, or from the side of the foam. The studies were carried out in the temperature range from 30 to 100 °C. The research results showed that for all positions of the heater, the parameter that makes the greatest contribution to the change in thermal conductivity is the cell size. Two open-cell foam samples of different sizes (d = 3.1 mm and d = 0.725 mm) have thermal conductivity values of 0.0452 and 0.0287 W/m⸱K, respectively, at 50 °C. In the case of similar cell sizes for any position of the heater, the determining factor is the type of cells. Mixed-cell foam (d = 3.28 mm) at 50 °C has a thermal conductivity value of 0.0377 W/m⸱K, and open-cell foam (d = 3.1 mm) at the same temperature has a thermal conductivity value of 0.0452 W/m⸱K. The same foam sample shows different values of effective thermal conductivity when changing the position of the heater. When the heater is located from below the foam, for example, mixed-cell foam (d = 3.4 mm) has higher values of thermal conductivity (0.0446 W/m⸱K), than if the heater is located from above (0.0390 W/m⸱K). There are different values of the effective thermal conductivity in the upper and lower parts of the samples when the heater is located from the side of the foam. At 80 °C the difference is 40% for the open-cell foam (d = 3.1 mm). Full article

In this paper, a characterization method for a lithium iron phosphate (LFP) pouch cell is presented and evaluated, using a method that applies to hybrid current pulses called hybrid power pulse characterization (HPPC). The purpose of the study is to validate the developed mathematical model capable of offering good results for virtualization of the cell with extrapolation capability for the entire battery. This type of characterization was tested before but on cells with low capacity where relatively small currents were applied. Here, the model is intended to be used for the development of electrical mobility applications, such as electric vehicles (EV) and electric vehicle supply equipment (EVSE), where high capacity and currents are required through the cell. The comparison between the real and simulated cell was made with two sets of results obtained from HPPC and using the FTP-72 speed profile by emulating real current conditions, where both show that the method is reliable under the tested conditions and can be used for the considered application.

Redox flow batteries hold promise as large-scale energy storage systems for off-grid electrification. The electrolyte is one of the key components of redox batteries. Inspired by the mechanism involved in solvents for extraction, a ternary deep eutectic solvent (DES) is demonstrated, in which glycerol is introduced into the original binary ethaline DES. Redox pairs (active substance) dissolved in the solvent have low charge transfer resistance. The results show that the viscosity of the solvent with the ratio of choline chloride to ethylene glycol to glycerol of 1:2:0.5 decreases from 51.2 mPa·s to 40.3 mPa·s after adding the redox pair, implying that the mass transfer resistance of redox pairs in this solvent is reduced. Subsequent cyclic voltammetry and impedance tests show that the electrochemical performance with the ternary DES as the electrolyte in redox flow batteries is improved. When the ratio of 1:2:0.5 ternary DES is used as the electrolyte, the power density of the battery (9.01 mW·cm−2) is 38.2% higher than that of the binary one (6.52 mW·cm−2). Fourier transform infrared spectroscopy further indicates that the introduction of glycerol breaks the hydrogen bond network of the solvent environment where the redox pair is located, unraveling the hydrogen bond supramolecular complex. Rational solvent design is an effective strategy to enhance the electrochemical performance of redox batteries. Full article

Lithium sulfur (Li-S) batteries stand out among many new batteries for their high energy density. However, the intermediate charge–discharge product dissolves easily into the electrolyte to produce a shuttle effect, which is a key factor limiting the rapid development of Li-S batteries. Among the various materials used to solve the challenges related to pure sulfur cathodes, biomass derived carbon materials are getting wider research attention. In this work, we report on the fabrication of cathode materials for Li-S batteries based on composites of sulfur and biomass-derived porous ramie carbon (RC), which are coated with multiwalled carbon nanotubes (MWCNTs). RC can not only adsorb polysulfide in its pores, but also provide conductive channels. At the same time, the MWCNTs coating further reduces the dissolution of polysulfides into the electrolyte and weakens the shuttle effect. The sulfur loading rate of RC is 66.3 wt.%. As a result, the initial discharge capacity of the battery is 1325.6 mAh·g−1 at 0.1 C long cycle, and it can still maintain 812.5 mAh·g−1 after 500 cycles. This work proposes an effective double protection strategy for the development of advanced Li-S batteries. Full article
