The growing demand for sustainable mobility is driving the need for high-energy lithium-ion batteries (LIBs) to meet the long-range requirements of vehicles. Consequently, materials with superior specific energy, such as silicon (Si), are increasingly being used over conventional graphite (Gr) as anode active materials due to Si’s significantly higher theoretical capacity. However, the incorporation of […]

Fast charging of lithium-ion batteries and range of electric cars are decisive criterions for the acceptance of electromobility in society. The requirements for fast charging differ depending on the application, which is often limited by the material system and cell design. In the aging process, the cell properties degrade, which can be accelerated by fast […]

Battery power capability has long been a challenge. All common methods to determine power capability, including the hybrid pulse power characterization (HPPC) test, are estimation methods where a model is fit to measured data and power capability is calculated rather than measured. Such estimation methods are inherently error prone due to the complex nonlinear characteristics […]

Aqueous magnesium-air (Mg-air) batteries possess a high theoretical voltage and specific energy density, extended shelf life, and safety features. They consist of a magnesium anode and an air electrode. However, their performance remains suboptimal due to several factors, the main ones being the overvoltage resulting from insoluble discharge products and rapid self-corrosion of magnesium anodes […]

A promising approach to increase the energy density of lithium ion batteries (LIBs) is the substitution of the state-of-the-art negative active material graphite by silicon (Si) due to the notably higher specific capacity of Si in comparison to graphite. However, Si exhibits enormous volume changes during lithiation/delithiation, which lead to high mechanical stress and degradation […]

A promising successor to the state-of-the-art lithium ion batteries is the lithium metal battery (LMB). The high theoretical specific capacity (3860 mAh g-1) and low gravimetric density (0.534 g cm-3) of lithium create auspicious conditions for a cell with a high energy density and specific energy. However, there are some challenges that complicate the entry […]

Increasing in volume of lithium-ion cells over their lifetime, known as the ageing effect of this cell type. This phenomenon is known as swelling. Swelling-related disadvantages include shortened lifespan, increased space requirements, excessive pressure on the cell, and the resulting safety issue. The accompanying safety problems are a source of worry for the development of […]
