The performance of symmetric supercapacitors with activated carbon electrodes, obtained from cellulose acetate microspheres as a precursor, has been studied using neutral aqueous sodium sulphate solutions as electrolytes. Although water-based electrolytes can safely operate in a broad temperature range, studies of supercapacitors beyond conventiona...

Layered Na0.8Co0.8Ti0.2O2 oxide crystallizes in the β-RbScO2 structure type (P2 modification) with Co(III) and Ti(IV) cations sharing the same crystallographic site in the metal-oxygen layers. It was synthesized as a single-phase material and characterized as a cathode in Na-and Na-ion batteries. A reversible capacity of about 110 mA h g −1 was obt...

Sodium transition metal oxides are one of the most promising cathode materials for future sodium ion batteries. Chemical flexibility of layered Na-oxides including cobalt enables its partial substitution by other...

To be competitive with combustion engine systems fast charging is one of the most driving aspects in the battery electric vehicle development. This study investigates Li-Ion cell properties and charging process parameters in regards to fast charging capabilities with the goal of an 80 % charge in 10 minutes. A workflow is established to get from pr...

20th International VDI Congress „Dritev“ – The most important powertrain development trends now digital & Corona-safe! Even in the corona crisis, the world of powertrain development does not stand still. Mobility and how it is driven remains the central focus of the automotive industry. The aim is to find good solutions in the area of conflict betw...

IAV has developed a multiphysics simulation approach to optimize the design of batteries. In 2014 IAV started battery technology development of bipolar Li-Ion battery system named EMBATT Chassis-embedded Energy (www.embatt.de). The target of the approach is to design more efficient battery systems to reach electric driving distances up to 1000 km....
