With the rapid growth of the electric vehicle industry, battery technology has received significant attention and research interest. To date, lithium-ion batteries (LIBs) remain the dominant choice for most applications due to their high energy/power density, efficiency, long cycle life, and relatively low production costs. However, lithium-ion technology also faces inherent limitations, with long charging […]

Carbon nanofibers (CNFs) synthesized through the electrospinning of Polyacrylonitrile (PAN) polymer have emerged as a significant class of nanomaterials, obtaining considerable attention in advanced materials research. The electrospinning technique allows for the precise engineering of nanofiber structures, offering a pathway to tailor properties such as high surface area, mechanical strength, and electrical conductivity. PAN-fibers are […]

The objective of this study was to develop a comprehensive method for characterizing the components of lithium-ion battery (LIB) electrolytes, including common lithium salts, additives, impurities, and degradation products. The analysis was conducted using High Performance Ion Chromatography (HPIC) coupled with conductivity detection (CD) and mass spectrometry (MS). Simulated LIB electrolytes, consisting of organic carbonate […]

As a result of the increasing demand for lithium-ion batteries (LIB), production capaci-ties in Germany and around the world will be greatly expanded over the next few years. In order to reduce the CO2 emissions of a lithium-ion battery over its entire life cycle, the current high energy requirements of battery cell production must be […]

Lithium-ion batteries (LIB) play a key role in the electrification of mobility, but resource management and reuse are still a major challenge. To improve this, new recycling methods must be developed to increase efficiency and recovery rates, facilitating the reuse of critical raw materials (CRMs) from spent LIBs. Currently, inorganic acids are widely used for […]

This poster presents the Joint Research Centre’s (JRC) efforts in supporting the implementation of the EU Batteries Regulation (EU) 2023/1542, focusing on sustainability across the battery lifecycle. This Regulation emphasizes battery performance and durability as a key sustainability metric and mandates the European Commission to introduce minimum requirements. The JRC supports the development of delegated […]

When analysing vehicle data from field tests in real world situations, it can often be helpful to be able to show differences between vehicles. A direct comparison of the data is usually not possible in a meaningful way, as the differences between the vehicles are often small. Even if two vehicles were driven on identical […]

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 […]
