Summary: We have successfully developed non-crystalline Li-ion solid electrolytes with high ionic conductivity using spin coating and annealing in air. The composition control and annealing temperature significantly affect the ionic conductivity. These electrolytes also exhibit low electronic conductivity and moderate Young's modulus, which can prevent Li dendrite formation. When in contact with Li metal, a stable but high impedance passivation layer is formed. These findings are valuable for engineering non-crystalline electrolytes for Li-metal batteries with high energy and power densities.

Summary: High spatial resolution in-operando Raman spectroscopy was used to study lithium deposition on graphite electrodes, showing that lithium is deposited and intercalated into graphite simultaneously. After 30 minutes, a second mechanism becomes dominant. The evolution of G and D bands of graphite and the lithium concentration in the electrolyte suggest that EC is slowly consumed after lithium plating begins.

Summary: An unconventional electroanalytical method using a 3D visualization of relaxation times was used to track processes in silicon anodes in lithium ion batteries. The study identified the formation of a solid electrolyte interphase on the anode composed of two layers with different relaxation times, which conventional impedance data analysis cannot achieve. Additionally, the research showed that the characteristic relaxation time of lithiation of the Si anode decreases upon cycling, indicating structural transformations that allow faster lithiation.

Summary: This article introduces a new method for early failure detection in lithium-ion batteries, which is based on wavelet spectral analysis to detect overcharge failure in voltage data obtained from cycling tests. The main frequencies of the voltage signal, harmonic components in regular cycling tests, and a low frequency pattern were identified. For the first time, battery failure can be anticipated by wavelet spectral analysis, which could reduce out-of-control explosions and fire risks.
