Unlike lithium-ion batteries (LIBs), where crystalline graphite is commonly used as the negative electrode material, disordered carbons are regarded as more promising for sodium-ion batteries (SIBs). However, further advances towards better reversibility and higher specific capacity are still needed to match or even exceed the properties of graphite in LIBs. The main challenge is the […]

Loss of lithium inventory (LLI) caused by SEI formation and other degradation mechanisms in Lithium-ion cells is one of the major reasons behind their capacity fade and shorter cycle life. Recent research in academia and industry has explored additives that sacrifice their lithium inventory to compensate for LLI. One such additive for LFP-based battery chemistries […]

Solid-state batteries (SSBs) with high energy density and enhanced safety are promising alternatives to conventional lithium-ion batteries with liquid electrolytes. Significant efforts in recent years have focused on improving the ionic conductivity of solid electrolytes, The highest ionic conductivity of inorganic electrolytes is already comparable to liquid electrolytes. However, the practical application of these electrolytes […]

A promising path for long-term energy storage is the production of e-fuels via Power-to-X processes (PtX). “Green” hydrogen is generated via water electrolysis and serves as a basic feedstock for the synthesis of chemicals and fuels such as methane, ammonia, methanol and other synthetic hydrocarbons. These fuels offer the advantage of an existing storage infrastructure […]

Estimating the state-of-charge SoC and state-of-health SoH of batteries is a key task for battery management systems. Observer based approaches such as the Dual-Extended-Kalman-Filter for joint SoC- and SoH-estimation have been proposed more than two decades ago and countless publications since then have shown the applicability of similar and advanced estimation methods. Two questions essential […]

Blend electrodes are widely used as lithium-ion battery cathodes and are getting more and more prominent on the anode side. The idea of blend electrodes is to combine characteristic properties of different active materials with the aim of improving overall cell performance or to adjust specific performance requirements according to the application of the cell. […]

Differential Voltage Analysis (DVA) is a commonly used method for investigating electrochemical processes, particularly at the electrode interfaces of batteries. It is especially useful for analysing phenomena such as phase transitions and intercalation processes within lithium-ion batteries. The successful use of DVA in studies of lithium-ion batteries raises the question of whether the method can […]
