The broad adoption of battery systems is increasing the complexity and size of lithium-ion battery packs. This increased complexity is raising the concerns related to the safety of lithium-ion batteries. In this context, this poster presents the development and validation of an integrated fault diagnosis identification method for lithium-ion battery packs. The algorithm is based […]

This study investigates the ionic conductivity of a mixture comprising 2-adamantanone and lithium bis(trifluoromethanesulfonyl)imide, with focus on the impact of temperature and residual tetrahydrofuran. Previous investigations have shown that the plastic crystal 2-adamantanone, when paired with lithium bis(trifluoromethanesulfonyl)imide, exhibits an ionic conductivity of 1.2 × 10-4 S/cm and a considerable oxidation potential of 5.1 V. […]

Lithium-ion batteries (LIBs) inevitably experience performance decay over their lifetime, including both capacity and power loss. This degradation reduces operational reliability, may pose safety risks under demanding operating conditions, and can increase warranty liability for manufacturers and system operators. Consequently, the development of reliable tools for predictive maintenance, battery health monitoring, and lifetime prognosis has […]

Leak testing is a mandatory quality control procedure for all batteries produced in the automotive industry. Ensuring the airtightness of the battery housing is essential to guarantee optimal performance, safety, lifespan, and cost efficiency. Over time, external environmental factors such as humidity may penetrate the housing and interact with internal components, leading to potential degradation […]

Although not replacing lithium-ion batteries completely, sodium-ion batteries are about to claim their share in the energy storage systems of tomorrow. The cathode material class of sodium layered oxides is similar to the widely employed lithium layered oxides in aspects of synthesis and processing. Nevertheless, there are challenges in adapting lab-scale as well as industrial […]

Polycaprolactone(PCL) solid polymer electrolytes (SPEs) offers a biodegradable sustainable alternative material for SPE battery systems, the interfacial dynamics between PCL and Li metal are insufficiently explored. This study utilizes operando ATR-FTIR spectroscopy to compare the interfacial behaviors of crosslinked (cl) and non-crosslinked PCL5LiTFSI SPEs. A series of electrochemical measurement reveals that the crosslinked network provides […]

Vinylene carbonate (VC) is often added to liquid electrolytes as an additive to facilitate the formation of a stable solid electrolyte interphase (SEI) during initial charging. The SEI prevents undesirable side reactions on the anode side and ensures high cycle stability. However, a disadvantage of VC is its instability at high voltages, such as those […]

In high nickel lithium ion batteries, a counterintuitive “spoon shaped” capacity fade has been reported during calendar aging, where capacity loss increases with state of charge (SOC) up to approximately 80 % before decreasing again toward 100 % SOC (Zülke et al., 2021, Majherova et al., 2025). This behavior challenges the conventional expectation that higher electrode potentials accelerate degradation […]

PyDPEET (“Python Data Processing for Electrical Energy Storage Technologies”) is an open-source Python package developed to facilitate battery data analysis. It targets a common problem: lab and field tests produce large, mixed datasets in many formats. Manual preprocessing is slow, error-prone, and hard to reproduce. PyDPEET offers a transparent workflow that standardises raw files, processes […]

Lithium–sulfur (Li–S) batteries offer very high theoretical capacity and energy density, but their practical application is limited by poor sulfur conductivity and the polysulfide shuttle effect, which leads to rapid capacity fading. In this work, polymer of intrinsic microporosity (PIM-1) was investigated as a sulfur host to improve cathode stability. PIM-1 possesses intrinsic micropores (90% […]
