Interphases play a vital role in lithium-ion batteries (LIBs), as they protect the electrodes and the electrolyte from various decomposition reactions during ongoing charge / discharge cycling, but also influence the resistance and Li-ion transport within the cells. Especially for next-generation LIBs, interphases are crucial to cope with the newly arising challenges, e.g. a higher […]

Today, lithium-ion batteries (LiBs) are widely used in various applications, offering high power, energy density and long cycle life. However, at sub-zero temperatures, their available energy, power and charging capability is limited. In order to address these issues, batteries can be pre-heated from low ambient temperatures to a higher temperature before operation. External heating methods, […]

To meet future customer demands for lithium-ion batteries (LIBs), it is necessary to increase their power density without sacrificing energy density. However, thicker electrodes, as necessary to reach this target, come with disadvantages such as limited Li-ion transport in the porous electrode structure.1 These limitations not only reduce the power capabilities of LIBs, but also […]

Introduction Lithium-ion capacitor (LIC) is a novel asymmetric capacitor possessing the combined electric double layer capacitors (EDLC) as well as lithium-ion batteries (LIB) and having characteristics of high power and high durability. Since activated carbon as a cathode material does not contain lithium-ion in it, lithium pre-doping process is required to manufacture LIC. Some LICs […]

Lithium-ion battery cell as a critical component for e-mobility and energy storage, has made significant progress since its born. Cell format has evolved over time into three major categories, cylindrical, pouch, prismatic and/or blade. Each format holds its own advantages & disadvantages and excels for its specific applications. Understanding the evolution as well as the […]

The ever-growing societal move towards sustainable forms of transportation, such as electric vehicles, motivates the research behind safe, efficient, and cost-effective use of lithium-ion batteries. Consequently, careful modelling of the electric, thermal, and ageing behaviour is paramount for all real-world applications. In the last decades, modelling of batteries using lumped equivalent electric circuit models has […]

Recycling of LIBs is essential because they comprise a high portion of valuable metals, such as Ni, Mn Co, Li and others including Al, Cu and Fe Storing batteries before recycling can cause fire hazard due to residual voltage left in the batteries. So Electrochemical Discharge is a safe, quick, inexpensive pretreatment solution (Battery need […]
