Abstract Solid‐state batteries are considered as a reasonable further development of lithium‐ion with liquid electrolytes. While expectations high, there still open questions concerning the choice materials, and resulting concepts for components full cells. On basis an analysis all materials concept options, roadmap solid‐state is presented, relying on both literature survey experts' opinions. Diverse cell different solid electrolytes may be developed up to commercial level, yet major...
The increase in battery demand, particularly from the mobility sector, has resulted a significant required production capacities. Europe is facing large-scale expansion of Currently, cell demand region accounts for approximately 25% global while only 10% capacities are located there. This motivated announcement large number projects over 2 TWh by 2030, which would mean overcapacity compared to projected European demand. In recent years, however, many announced Gigafactories have been delayed...
Abstract Batteries are critical to mitigate global warming, with battery electric vehicles as the backbone of low-carbon transport and main driver advances demand for technology. However, future production batteries remain uncertain, while ambition strengthen national capabilities self-sufficiency is gaining momentum. In this study, leveraging probabilistic modelling, we assessed Europe’s capability meet its high-energy via domestic cell production. We found that in Europe likely exceed 1.0...
Electric manipulation of magnetic properties is a key problem materials research. To fulfill the requirements modern electronics, these processes must be shifted to high frequencies. In multiferroic materials, this may achieved by electric and control their fundamental excitations. Here we identify vibrations in iron borates that are simultaneously sensitive external fields.

We investigated the static and dynamic magnetic properties of polar ferrimagnet Mn$_2$Mo$_3$O$_8$ in three magnetically ordered phases via magnetization, torque, THz absorption spectroscopy measurements. The observed field dependence spin-wave resonances, including Brillouin zone-center zone-boundary excitations, are well described by an extended two-sublattice antiferromagnetic classical mean-field model. In this orbitally quenched system, competing weak easy-plane easy-axis single-ion...
Abstract A dense system of independent oscillators, connected only by their interaction with the same cavity excitation mode, will radiate coherently, which effect is termed superradiance. In several cases, especially if density oscillators high, superradiant decay oscillators’ excited state may dominate intrinsic relaxation processes. At low frequencies, this limit can be achieved cyclotron resonance in two-dimensional electron gases. those experiments, coupled to electric field light,...
Violation of time reversal and spatial inversion symmetries has profound consequences for elementary particles cosmology. Spontaneous breaking these at phase transitions gives rise to unconventional physical phenomena in condensed matter systems, such as ferroelectricity induced by magnetic spirals, electromagnons, non-reciprocal propagation light spin waves, the linear magnetoelectric (ME) effect - electric polarization proportional applied field magnetization field. Here, we report...
We investigate the phonon spectrum of pure and rare-earth substituted langasites. For electric fields oriented along $c$ axis, a strong low-frequency is observed, softening at lower temperature in all samples studied.

Softening with increasing mass substitutes further suggests that langasites are close to structural instability...
A dense system of independent oscillators, connected only by their interaction with the same cavity excitation mode, will radiate coherently, which effect is termed superradiance. In several cases, especially if density oscillators high, superradiance may dominate intrinsic relaxation processes.
