…ed manner, but uncontrollably in the form of thermal energy. In case of such a failure, the thermal energy released by a lithium ion battery may be 7 to 11 times higher than the energy stored electrically. The produced heat accelerates the reaction, resulting in a critical overheating of the battery. In addition, it is possible that cathode materials disintegrate at high temperatures. This reaction also produces heat (exothermic reaction) and…

…thors of the investigation conclude, that a faster rate of decline in the state-of-health (SoH) for the 30 kWh variants over the 24 kWh variants is detected. Some of the 30 kWh variants had already lost 20 % of the battery capacity after only two years of operation.

The Danish Battery Society is organizing a half-day session on solid-state batteries at the Nordic Conference on Ceramic and Glass Technology 2018 and it will be possible for DBS members to participate. More info on price, time and sign-up for DBS members will follow later. All major car producers expect solid-state batteries to enable the next leap forward in battery energy density by enabling the use of metallic lithium as the anode. The…

…g and controlling the complex and dynamic processes in the electrodes, electrolytes and battery interfaces hold the key to develop ultra-performant and sustainable batteries. Atomic-scale simulations have reached predictive accuracy in many aspects of the materials design, characterization and discovery process. Here, we provide a number of recent examples of how density functional theory (DFT) simulations supported by machine learning and…

Uddrag fra berlingske.dk: “Virksomheden Lithium Balance har udviklet en energieffektiv løsning på et af de helt store problemer i energibranchen i disse år, nemlig lagring af strøm. Nu lancerer virksomheden, der er direkte konkurrent til Tesla, sine første kæmpebatterier på lystbådehavnen i Ballen på Samsø. Den lille danske vækstvirksomhed Lithium Balance er efter fire-fem års udviklingsarbejde klar til at sende sine første nye,…
