Volvo Cars is taking a bold lead with electrification. By 2030 the goal is to only produce electric vehicles (EVs). Efficient design solutions for energy storage systems are being explored and designed to drive this ambition. Moreover, novel evaluation tools are being developed to assure the safety and reliability of the systems during operation. In […]

Short charging times of BEVs and a long battery life are seen as key enabler for a convenient e-mobility and a broad customer acceptance. The battery thermal management system plays an important role to meet these requirements. Battery immersion cooling is a very promising approach to manage the increased heat losses during fast charging and […]

Thermal runaway (TR) of lithium-ion cells results in an enormous release of heat, which can also bring the neighboring cells in the module into a safety-critical temperature range. To avoid TR propagation from cell to cell while simultaneously maximizing energy density on module and pack level, an optimal design of safety measures is necessary. Therefore, […]

End-of-life for lithium-ion batteries is commonly defined as 80% state-of-health (SOH). In some batteries and applications, this coincides with a steep increase in degradation rate. This is referred to as nonlinear aging or an aging knee. If the operating conditions are left unchanged the battery continues on the steep aging trajectory until it is unusable. […]

The aim of the project „Open Battery“ is to develop a construction kit with all devices and modules that are needed to build a photovoltaic (PV) system with energy storage for use in households, small farms or small industrial establishments. The operation of the system is considered not only in Germany or Europe, but also […]

Solid-state lithium-ion batteries are promising candidates as next generation of energy storage devices. Unlike conventional lithium-ion batteries, they comprise a solid electrolyte (SE) instead of a liquid organic one. The use of SEs allow an increase in the battery energy density, which is required for automotive applications [1]. Among SE categories, sulfide based solid electrolytes […]

The ASSB is the next generation technology, which receives a lot of attention as a promised candidate to replace conventional LIBs due to its higher energy in future. The current challenge is to scale up the production and manufacturing processes of each battery component, like the solid electrolyte (SE) and composite cathode. Due to the […]

The high specific energy density of the Li-oxygen battery makes the system an extremely attractive and intensively investigated technology for storing electricity in the future. Central challenges in materials science lie in the electrochemical stability of the electrolyte against the reactive oxygen species and against Li metal, the dendrite-free cyclization of the Li-based structured anode, […]

As an excellent choice of energy storage, batteries have been integrated into not only a wide range of industrial applications, but also everyone’s everyday life. At the moment, Li-ion batteries are dominating the market with regard to many applications, as well as in research areas. However, because of the concerns including safety issues, the possible […]

Often, to address the challenges of the lithium ion battery active materials in terms of poor cycling performance, interface instability, severe volume changes and incompatibility with the carbonate-based electrolyte, different electrolyte components are combined together. Although a synergistic effect would bring up the advantages of different electrolyte constituents, their interaction is sometimes neglected. In this […]
