Special Issue Information

Dear Colleagues,

The search for alternative energy is a significant worldwide concern because of fossil fuel diminution and environmental complications. Over the past few decades, fossil fuels have been extracted from the Earth's crust to meet rising energy needs. However, the energy derived from fossil fuels cannot fulfil future demands because of rapid population growth. Additionally, environmental worries are also associated with fossil fuel-related energy. When fossil fuels are converted into energy, they release a considerable amount of CO2 and many other greenhouse gases as destructive by-products. Based on this apprehension, worldwide, researchers focus on various ideas and developments to derive energy in clean and green forms from renewable energy sources such as solar, wind, geo, hydro, and bio energies.

Secondary energy carriers derived from renewable sources are the future. The function and utilization of energy carriers majorly depend on energy storage/conversion systems (ESS). The major ESSs are fuel cells, batteries, and supercapacitors. The performances of ESSs are related to the function of membrane and electrode materials.

This Special Issue, “Polymer Materials for Energy Storage Applications”, primarily covers polymer materials as membranes/separators and electrode materials for fuel cells, batteries, and supercapacitors. The scope of interests includes, but is not limited to, the following topics:

  • Membranes for fuel cells (proton-exchange membrane fuel cells, direct methanol fuel cells, alkaline fuel cells, microbial fuel cells, phosphoric acid fuel cells, unitized regenerative fuel cells, etc.);
  • Polymer separator for metal-ion batteries, lithium-sulphur batteries, lithium polymer batteries, etc.;
  • Membranes/separators for redox flow batteries;
  • Conducting polymer-based supercapacitor electrode materials;
  • Polymer composites for solid and aqueous batteries;
  • Polymers for hydrogen storage systems;
  • Bio-polymer-derived electrode materials.

Simultaneously high-rate and high-safety lithium-ion batteries (LIBs) have long been the research focus in both academia and industry. In this study, a multifunctional composite membrane fabricated by incorporating poly(vinylidene fluoride) (PVDF) with magnesium carbonate hydroxide (MCH) nanofibers was reported for the first time. Compared to commercial polypropylene (PP) membranes and neat PVDF membranes, the composite membrane exhibits various excellent properties, including higher porosity (85.9%) and electrolyte wettability (539.8%), better ionic conductivity (1.4 mS·cm−1), and lower interfacial resistance (93.3 Ω). It can remain dimensionally stable up to 180 °C, preventing LIBs from fast internal short-circuiting at the beginning of a thermal runaway situation. When a coin cell assembled with this composite membrane was tested at a high temperature (100 °C), it showed superior charge–discharge performance across 100 cycles. Furthermore, this composite membrane demonstrated greatly improved flame retardancy compared with PP and PVDF membranes. We anticipate that this multifunctional membrane will be a promising separator candidate for next-generation LIBs and other energy storage devices, in order to meet rate and safety requirements.

The type IV hydrogen storage tank with a polymer liner is a promising storage solution for fuel cell electric vehicles (FCEVs). The polymer liner reduces the weight and improves the storage density of tanks. However, hydrogen commonly permeates through the liner, especially at high pressure. If there is rapid decompression, damage may occur due to the internal hydrogen concentration, as the concentration inside creates the pressure difference. Thus, a comprehensive understanding of the decompression damage is significant for the development of a suitable liner material and the commercialization of the type IV hydrogen storage tank. This study discusses the decompression damage mechanism of the polymer liner, which includes damage characterizations and evaluations, influential factors, and damage prediction. Finally, some future research directions are proposed to further investigate and optimize tanks. Full article

The integration of polymer materials with self-healing features into advanced lithium batteries is a promising and attractive approach to mitigate degradation and, thus, improve the performance and reliability of batteries. Polymeric materials with an ability to autonomously repair themselves after damage may compensate for the mechanical rupture of an electrolyte, prevent the cracking and pulverization of electrodes or stabilize a solid electrolyte interface (SEI), thus prolonging the cycling lifetime of a battery while simultaneously tackling financial and safety issues. This paper comprehensively reviews various categories of self-healing polymer materials for application as electrolytes and adaptive coatings for electrodes in lithium-ion (LIBs) and lithium metal batteries (LMBs). We discuss the opportunities and current challenges in the development of self-healable polymeric materials for lithium batteries in terms of their synthesis, characterization and underlying self-healing mechanism, as well as performance, validation and optimization.
