In recent years, sodium-ion batteries (SIB) have become of great interest in energy storage systems. SIBs offer advantages, including the availability of raw materials, the potential for lower costs, and the possibility of discarding copper as the anode collector material. While several works investigate the calendric and cyclic aging of lithium-ion batteries (Schmalstieg et al. […]

Around four billion discarded tires are in landfills annually, highlighting the need for sustainable recycling methods. One solution is to transform waste tires into carbon powder as active anode material for alkali-ion battery. However, heavy metals and other contaminants in tires reduce the electrochemical performance of the resulting carbon material. Traditional approaches often employ concentrated […]

Thermal gradients inside Lithium-Ion batteries are responsible for current inhomogeneities that accelerate cell degradation. For this reason, accurate thermal modelling is key to designing more reliable cells and packs and a thermal model should be able to predict heat generation accurately. Heat generation consists of reversible and irreversible contributions, the reversible component being governed by […]

Given the ongoing discussion about the slowdown in the electric vehicle market, more and more cell production plants in the Western world are being put on hold or get even completely cancelled. Ramping-up cell production with limited experience and an immature products proves highly challenging. Additionally, external factors such as strict regulatory requirements, political changes, […]

One of the major customers‘ demands on battery electric vehicles is the lifetime of the battery as a potential cost driver in the future and influencing factor on sales value. Battery aging is influenced by degradation mechanisms, driven by storage and operating conditions, known as calendric and cyclic aging. These mechanisms lead to a loss […]

Sodium-ion batteries (SIBs) are considered a more sustainable, resource saving, and cost-effective alternative to lithium-ion batteries (LIBs) as they can be designed without using critical or scarce raw materials and compounds such as cobalt, copper, lithium or graphite [1,2]. These advantages on the material level, along with the ability of using existing manufacturing equipment, have […]

Lithium-ion batteries (LIBs) demand for electromobility, portable electronics and gride energy storage applications is ramping up dramatically. This has heightened the need for battery precursors materials to supply the emerging gigafactories globally. However, in the light of the scarcity of critical raw material resources such as lithium, cobalt, and nickel, developing efficient and affordable recycling […]

The formation process is a crucial and costly final step in manufacturing battery cells, accounting for up to 33% [1] of production cost. During this stage, a protective interphase layers are stablished at the electrochemically active interfaces that enable a stable operation of the cell outside the electrolyte’s electrochemical stability window. The formation process, in […]
