Estimating Lithium-Ion Battery State of Charge and Parameters Using a Continuous-Discrete Extended Kalman Filter

open access: yesEnergies, 2017
A real-time determination of battery parameters is challenging because batteries are non-linear, time-varying systems. The transient behaviour of lithium-ion batteries is modelled by a Thevenin-equivalent circuit with two time constants characterising ...

Behavior of tungsten fiber-reinforced tungsten based on single fiber push-out study

open access: yesNuclear Materials and Energy, 2016
To overcome the intrinsic brittleness of tungsten (W), a tungsten fiber-reinforced tungsten-composite material (Wf/W) is under development. The composite addresses the brittleness of W by extrinsic toughening through the introduction of energy ...

Atomic Layer Deposition‐Modified Bifunctional Electrocatalysts for Rechargeable Zinc‐Air Batteries: Boosting Activity and Cycle Life

open access: yesAdvanced Energy Materials, EarlyView.
The transition metal oxide is precisely deposited on the catalyst surface via atomic layer deposition (ALD), forming a protective layer with catalytic activity. Electrochemical experiments, theoretical calculations, and in situ X‐ray absorption spectroscopy (XAS) battery testing collectively demonstrate that the modified transition metal oxide ...
