The prospects are considered of deploying batteries and fuel cells in order to reduce the carbon emissions from various modes of transport. It is proposed that the government has not done enough to advance these technologies and that Britain is lagging behind other countries. The adequacy of Britain’s future supplies of energy is called into question.

This study, conducted with Northvolt, examines battery system recyclability and disassembly dynamics. It introduces indices for material and product recyclability, along with disassembly time assessment. The goal is to create a design tool to streamline the evaluation of battery disassembly, aiding in designing recyclable and serviceable components. These methodologies serve as a blueprint for enhancing battery systems' overall sustainability and circularity design, presenting a base for future product development in alignment with environmental and economic objectives.

Scanning electron microscopes (SEMs) are a popular analytical tool due to their high spatial resolution, large depth of field, and analytical capabilities. However, in many cases, the large-scale installation and cost of SEMs can be a barrier to entry for smaller laboratories or facilities. The introduction of a more compact benchtop SEM has changed the landscape, enabling scientists in many fields to adopt the technology and revolutionize research. Benchtop SEMs can be used in a variety of industries including materials science, pharmaceutical research, energy exploration, science education, and academia. These industries require analysis at the nanoscale for quality control, failure analysis, and R&D, for all of which the benchtop SEM is perfectly positioned to provide necessary detail. These advantages and new developments in the technology have made the benchtop SEM a widely available and well-accepted tool.

Transmission electron microscopy (TEM) offers significant potential for studying chemical changes that occur in a battery electrode at a spatial resolution approaching atomic dimensions, provided a representative specimen can be prepared. The purpose of this paper is to show that it is possible to examine an electrode in the charged condition using TEM, while avoiding major changes in chemistry from specimen preparation. We also demonstrate the power of electron energy-loss spectroscopy (EELS) for phase identification at high spatial resolution. The origin of “fading” of an electrode after repeated charge-discharge cycling is also discussed.

Energy density and safety are the main factors that govern the development of the rechargeable battery technology. Currently, batteries beyond typical Li-ion batteries such as those based on solid-state electrolytes (SSEs) or other active elements (e.g., Na or Mg) are being examined as alternatives. For example, SSEs that would enable stable and reliable operation of all-solid-state Li-, Na-, and Mg-based batteries, with preferably improved capacity, are considered to be one of the most desired inventions. Lightweight complex metal hydrides are a family of solid compounds that were recently discovered to have extraordinary ionic conductivities and, in some cases, electrochemical properties that enabled battery reversibility. Consequently, they have become one of the promising electrolyte materials for future development of electrochemical storage devices. In this work, we present an overview of a wide range of lightweight hydride-based materials that could be used as electrolytes and/or anodes for mono-/divalent batteries and have a pivotal role in the implementation of new technological solutions in the field of electrochemistry.

Graphite has been widely used as a negative electrode material in lithium-ion batteries, and recently it has attracted attention for its use in potassium-ion batteries. In this study, the first in situ X-ray diffraction characterisation of a K/graphite electrochemical cell is performed. Various graphite intercalation compounds are found, including the stage three KC36 and stage one KC8 compounds, along with the disappearance of the graphite during the potassiation process. These results show new insights on the non-equilibrium states of potassium-ion intercalation into graphite in K/graphite electrochemical cells.

In recent years, lithium received increasing attention as lithium-ion rechargeablebatteries appear to be the most promising candidates for future electric vehicles. Severalstudies forecast a strong increase in demand most likely brought about with theimplementation of lithium-ion batteries in the automotive sector. Thus, the availabilityof lithium could be an important constraint for this emerging technology. Concerninglithium availability the future developments of supply and demand as well as the recyclingpotential play major roles. In respect of recycling it has to be distinguished in generalbetween dissipative and non-dissipative applications. As several studies (e.g. 1 G. Angerer, F. Marscheider-Weidemann, M. Wendl, M.Wietschel, Raw materials for emerging technologies: the case of lithium, Karlsuhe 2009)predict lithium recycling to play an important role for future lithium availability therecyclability of lithium in different applications has to be analysed for estimating thecontribution of lithium recycling to future supply.
