Ultrasonic diagnostics offer a promising method for monitoring lithium-ion batteries by detecting mechanical changes that occur during cycling and aging. While conventional ultrasonic analysis often relies on time-of-flight (ToF) measurements, recent studies show that frequency-domain approaches can provide more robust correlations with battery state. In this work, ultrasonic spectroscopy is used to investigate acoustic resonances […]

State of health (SOH) estimation in lithium-ion batteries remains challenging in electric vehicles due to the interplay of multiple aging mechanisms. This work presents a DVA-based capacity estimation method for Nickel–Manganese–Cobalt (NMC) cylindrical cells, designed for integration into Battery Management Systems (BMS) to support predictive maintenance. The method estimates cell capacity by tracking the peak […]

In this work we analyzed the influence of precursor selection on the performance of lithium iron phosphate (LFP) cathode active material (CAM). We used different iron oxide battery grades from the LANXESS portfolio of, as well as an iron phosphate as precursor material for lithium iron phosphate cathode materials and tested the resulting lithium iron […]

Lithium-ion pouch cells offer high packaging efficiency because of their lightweight, flexible pouch foil. Due to the absence of a rigid casing, the cells are typically mechanically constrained or compressed by the battery pack housing for protection and to ensure mechanical integrity. While moderate pressure can enhance cell performance by improving electrode-particle contact, excessive or […]

Many existing trading algorithms for battery storage systems operate as “black boxes”, limiting insight into their decision logic and interaction with electricity markets. To address this, we present a modular, rule-based trading framework for battery energy storage systems (BESS) in the intraday continuous market, coupled with a simulated order book matching mechanism. The focus is […]

Aqueous processing of positive electrodes for lithium-ion batteries offers significant ecological and economic advantages over the established NMP-based route. However, nickel-rich layered oxide cathode materials such as NMC811 are sensitive to water: upon contact, lithium leaches from the material, hydroxide and carbonate surface layers form, and electrochemical performance deteriorates. Two mechanisms have been proposed to […]

In recent years, increasing environmental awareness combined with political and economic incentives has driven the establishment of stricter regulations for battery recycling. Alongside the rapid progress in solid-state battery research, it has become essential to explore potential strategies for the recovery of valuable materials even prior to the large-scale commercialization of these technologies. With the […]

Especially in the application of stationary energy storage devices, redox flow batteries have significant advantages over Lithium-based systems. These advantages include the ability to scale energy and power independently, the use of non-flammable materials and the potential of more cost-effective scaling. In the field of redox-flow batteries, the primary focus is on vanadium-based systems. However, […]

Achieving high stability at high voltage remains a major challenge for Ni-rich NCM 811 cathodes. Herein, we report for the first time metal phosphides as surface decoration materials to mitigate capacity fading, structural degradation, and interfacial instability. Fe2P, Ni2P, and Ni12P5 were selected due to their sustainability, low cost, non-toxicity, and unique phase diagram properties. […]
