As complex electrochemical energy storage devices, lithium-ion batteries (LIBs) exhibit coupled multiphysics responses across diverse operational conditions. A well-designed decoupling evaluation offers a more significant opportunity to reveal the interaction and correlation mechanisms between the multiphysics. In the battery packaging design, practical multi-field evaluation of LIBs provides a reasonable solution for thermal management and structural […]

Preliminary tests have shown that it is possible to manufacture functional silicon (Si) electrodes using only one single polymer, polydopamine (PDA). With a partial carbonisation process after electrode coating, one part of the PDA maintains its characteristics as binder. Simultaneously, another part of the PDA breaks down to carbon material to improve the electrical conductivity […]

In recent years, battery cells based on aluminium-ion chemistry (AIB) have demonstrated their potential as a performance-dominant technology in various studies at laboratory cell size, e.g. in PAT systems. While the reported performance seems impressive, the transferability and thus comparability with other technologies is difficult. With the first successful small format single layer pouch cell […]

The current trend in the electric vehicle industry to shift back from Li(Ni,Co,Mn)O2 (NCM) to low-cost LiFePO4 (LFP) in batteries (47 % market share predicted by 2026[1]) poses a challenge for recyclers. While NCM batteries contain valuable materials such as cobalt and nickel, the profitability of recycling LFP batteries using the conventional recycling processes (i.e., […]

The importance of air tightness in the battery’s production aims to prevent the battery from being impacted by the environment with undesirable effects like pressure, temperature change and the appearance of moisture in the housing. The quality control process occurs in the production line and is a mandatory step for every battery that is produced. […]

A key challenge facing future battery technologies is finding alternatives for currently used raw materials, which are often expensive and are becoming increasingly scarce (e.g. Li, Co, Ni). Thus, to tackle the strongly increasing demand of electrochemical storage, a variety of battery technologies will be needed adjusted to the specific requirements of each individual application. […]

Lithium-free Al-graphite-dual-ion batteries (AGDIB) have gained much attention due to their low-cost and sustainability. Commercial Al-foils and natural graphite are employed as electrode materials, ionic liquids such as AlCl3/[EMIm]Cl as anolyte. Al2Cl7– and AlCl4– within the anolyte are responsible for Al dissolution and plating, whereas AlCl4– is (de)intercalated between layers of graphite. While offering a […]

This poster describes our work of Bayesian optimization of prelithiation process in different scale experiments. Bayesian optimization is a rapidly growing data science technique to find an optimal parameter set with a lower cost. We have evaluated this technique with focusing on a promising process step in a lithium-ion battery production, called prelithiation. Prelithiation is […]

The Launch management of battery cell production lines lacks a clear state of the art description. As a consequence, high scrap rates and costs are alsmost inevitable associated with the launch of new battery cell production lines. Furthermore, automotive OEMs cannot meet their timelines for new model introductions to further increase the share of electrical […]

The ongoing electrification of the transportation sector has sparked the search for high energy dense batteries in recent years, which led to a revived interest in lithium metal as an anode material. The lithium-metal battery (LMB), introduced nearly half a century ago, was replaced quickly after its initial discovery due to rapid capacity fading and […]
