Special Issue Information

Dear Colleagues,

Advances in the storage of electrical energy have always been the driving force for the improvement of our society, from communications to transportation and electricity delivery. Electrochemical energy storage is critical to underpinning sustainable consumer electronics, electric vehicles, and industry smart grids. Lithium-ion batteries (LIBs) have been dominant in the market due to their desirable energy and power densities, and have been recognized by the 2019 Nobel Prize in Chemistry. However, the energy densities of LIBs have to be continually increased to meet the market demand for lighter batteries with longer service lives. On the other hand, significant concerns have been raised regarding the supply chain and sustainability of LIBs, as their key elements, including lithium, cobalt, and nickel, are at risk of shortage in the earth's crust. Therefore, developing high-capacity anode materials such as Li metal and Si anodes and cathode materials with less Co or Ni to enhance the energy density and sustainability of LIBs simultaneously is urgent. Moreover, engineering the microstructures of these high capacity electrode materials to enhance their performance is highly desirable. Developing advanced battery recycling methods to recycle the key elements of spent LIBs is also important to save resources and boost sustainability.

Besides LIBs, the development of other battery systems based on low-cost and abundant materials is also important for specific applications. For example, viable large-scale energy storage devices must be of appropriate capacity, safe to operate, durable, and utilize low-cost materials and device production methods. In recent years, sodium, potassium, and aqueous zinc ion batteries have attracted strong attention as complementary technologies to LIBs and for smart grid applications. However, challenges still remain regarding the electrode materials, electrolytes, electrode–electrolyte interface, and large-scale demonstration.

This Special Issue will focus on new ideas in developing advanced and sustainable battery technology, which includes materials’ microstructure design and surface modification, new electrolytes, electrode–electrolyte interface, and mechanism exploration via advanced characterization and modeling. Both original research and review articles are welcome in this Special Issue. Areas of interest include, but are not limited to, the following:

  • Li-ion batteries;
  • Li metal batteries;
  • Na-ion batteries;
  • K-ion batteries;
  • Multivalent batteries;
  • Aqueous batteries;
  • Solid-state batteries;
  • Battery recycling

The specificities of temperature-dependent electrochemical modelling strategies of 18650 Li-ion batteries were investigated in pseudo-2D, 2D and 3D domains using finite element analysis. Emphasis was placed on exploring the challenges associated with the geometric representation of the batteries in each domain, as well as analysing the performance of coupled thermal-electrochemical models. The results of the simulations were compared with real reference measurements, where temperature data were collected using temperature sensors and a thermal camera. It was highlighted that the spiral geometry provides the most realistic results in terms of the temperature distribution, as its layered structure allows for a detailed realisation of the radial heat transfer within the cell. On the other hand, the 3D-lumped thermal model is able to recover the temperature distribution in the axial direction of the cell and to reveal the influence of the cell cap and the cell wall on the thermal behaviour of the cell. The effect of cooling is an important factor that can be introduced in the models as a boundary condition by heat convection or heat flux. It has been shown that both regulated and unregulated (i.e., natural) cooling conditions can be achieved using an appropriate choice of the rate and type of cooling applied. Full article
