An essential factor for the effective integration of lithium-ion batteries into a greener energy system is the establishment of a sustainable and eco-friendly manufacturing process for battery components. While the water-based PFAS-binder-free method is well-established for carbon-based anodes, a comparable approach encounters numerous hurdles when applied to cathode materials, particularly those with high nickel content. […]

One of the most commonly used cathode active materials (CAM) are lithium nickel manganese cobalt oxides often referred to NMC with the general formula of Li[NixMnyCoz]O2. In this work, polycrystalline and single-crystalline NMC811 active materials are used to investigate the influence of the particle morphology on the evolution of SOC heterogeneities. Therefore, LIB pouch cells […]

Lithium-Sulfur Batteries are a promising future battery technology due to their characteristics, including high theoretical specific capacities of up to 1670 Ah/kg and gravimetric energy densities of 2600 Wh/kg [1]. These values surpass those of conventional lithium-ion batteries. Moreover, sulfur, a key component in Li-S batteries, is abundant and environmentally benign compared to materials commonly […]

Established recycling methods for lithium-ion batteries are highly energy-intensive or chemical-consuming, therefore, a new electrochemistry-based recycling method was developed aiming to overcome these challenges. Leaching of cathode materials (LCO and NCM) in sulfuric acid is performed without an addition of further chemicals (e. g. hydrogen peroxide). Instead, the in-situ electrogeneration of peroxydisulfate on a boron […]

Abuse testing and failure recreation of thermal runaway in lithium-ion battery packs within Exponent’s London laboratory has shown how battery fires initiate and propagate. Here we demonstrate how even small amounts of moisture ingress to sensitive electronic components of the battery pack, such as the battery protection circuitry, can lead to thermal runaway of the […]

Carbon Nanotubes (CNTs) have been hailed as beneficial conductive additive material in Silicon-based anodes due to their unique features such as high electronic conductivity and the ability to mitigate the volume expansion of lithiated Silicon anode-based battery cells. However, both CNTs and Silicon irreversibly consume an enormous amount of Li-Ion inventory to form the SEI-layer, […]
