In addition to the costs, high energy density, and fast-charging capability, safety of Li-ion batteries is most important – even after long-term usage or abusive conditions. A new combination of Accelerating Rate Calorimetry (ARC) coupled with a mass spectrometer (MS) [1] to study commercial 18650-type Li-ion cells will be shown. This novel ARC-MS setup allows […]


Climate change and the limited availability of fossil fuels do not just increase the demand for renewable energy sources, but also for new battery technologies. A higher amount of battery-powered cars can reduce the amount of emitted greenhouse gases significantly. Photovoltaic and wind power are excellent alternatives to conventional energy sources. However, those suffer from […]


Available energy is one of the most relevant parameters for dimensioning and design of battery systems. The discharge duration of a battery and its dependence on the amplitude of the discharge current are described by Peukert’s equation. In practice at the beginning of a development process, development engineers are often only expected to make estimates […]


The quick determination of battery capacity by indirect measurements is a highly desired feature in the industry. In this poster, a dataset is presented consisting of six 2.6 Ah (1C) cells, aged under different conditions for 1000 equivalent cycles. A strong positive correlation is detected between the measured discharge capacity at 1C and the capacitance […]


The german based cerman.power+ Battery GmbH, Nordhausen offers the latest battery cell technology (Lithium, solid state), from design and materials to components and cells along the development chain. They already have a good name on the market and have already received a patent from the German Patent Office for the so-called TROIKA process (December 2020). […]


The industrially-relevant cell formats PHEV1 (prismatic), multi-layer pouch, 18650 and 21700 (cylindrical) [1] are directly compared by experiments. The direct comparison becomes possible by using the same anode (graphite), cathode (NMC622), separator, and electrolyte. Our experiments show that the main differences between these formats are their capacities, sizes, as well as tab and the jellyroll/stack […]


The porous carbon derived for batteries and supercapacitor have increased research consideration because of low cost, easy to fabricate, and environmentally friendly. In this study, we successfully synthesized the porous carbon with rod-like structure from tea using carbonization, followed by activated by KOH and KNO3 to produce having high porosity carbon with large surface area […]


Most lithium-ion batteries contain areas of active material with no opposing counter-electrode as a result of the production process. This overhang, which is formed by the graphite anode in most lithium-ion battery designs, contributes to the overall cell performance as a sink or a source of cyclable lithium inventory over time periods ranging from days […]


All-solid-state batteries offer great potential as next-generation batteries as they enable the use of a lithium metal anode. This technology offers the potential to improve fast charging properties, the achievable energy density as well as safety [1]. In order to develop competitive all-solid-state batteries, cost efficient and highly scalable manufacturing methods need to be identified […]


Batteries stacks are made of cells in certain series-parallel arrangements. Unfortunately, cell performance degrades over time in terms of capacity, internal resistance, or self-discharge rate. In addition, degradation rates are heterogeneous, leading to cell-to-cell variations. Balancing systems can be used to equalize those differences. Dissipative or non-dissipative systems, so-called passive or active balancing, can be […]
