The performances of the batteries need to be more and more improved to reach the requirements of applications like electric cars or energy storage. The new generation of batteries needs to store more energy and to charge faster with a price always reduced. Lithium-sulfur batteries are an interesting alternative to conventional batteries due to the […]

Self-discharge in battery cells remains an important issue in the storage of electrical energy. Recently, Jeff Dahns / Michael Metzgers group discovered that the impurity dimethyl terephthalate (DMT), which leaches from the PET-based fixing tape, used to hold the cell stack in place, causes self-discharge in lithium-ion batteries. Here, we report the leaching of 2,4-di-tert-butylphenol […]

The State of Health (SOH) is a critical parameter in a Battery Management System (BMS) that indicates the aging condition of the battery. The SOH is typically defined as the ratio between the current maximum capacity of the battery and its nominal capacity, which is usually measured through a full discharge cycle at a rated […]

The state of health (SoH) of lithium-ion cells is crucial for ensuring optimal performance in critical applications such as electric vehicles (EVs) and energy storage systems. This work presents a fast, non-invasive method for estimating SoH using Electrochemical Impedance Spectroscopy (EIS) and Equivalent Electrical Circuit (EEC) models. Unlike conventional methods requiring lengthy charge-discharge cycles, the […]
