Semi-flowable Zn semi-solid electrodes as renewable energy carrier for refillable Zn–Air batteries

Novel semi-solid electrolytes for Li-based batteries

Electrolytes of relevance for high performance batteries have to fulfill a variety of restrictive criteria: Not only is high Li conductivity a necessary condition to avoid too high losses, also an anion contribution as low as possible is desired as otherwise concentration polarization occurs [1]. Furthermore, the electrolyte should be mechanically stable. Beyond that, it should wet the electrod...

Materials in conducting suspension ( semi - solid ) electrodes for water and energy technologies

Solid electrolyte interphase in semi-solid flow batteries: a wolf in sheep's clothing.

The formation of the alkyl carbonate-derived solid electrolyte interphase (SEI) enables the use of active materials operating at very cathodic potentials in Li-ion batteries. However, the SEI in semi-solid flow batteries results in a hindered electron transfer between a fluid electrode and the current collector restricting the operating potentials to ca. 0.8 V vs. Li/Li(+) for EC-based electrol...

Static and Dynamic Studies on LiNi1/3Co1/3Mn1/3O2‐Based Suspensions for Semi‐Solid Flow Batteries

LiNi1/3 Co1/3 Mn1/3 O2 (LNCM)-based suspensions for semi-solid flow batteries (SSFB) have been investigated by galvanostatic charge/discharge an electrochemical impedance spectroscopy (EIS). The resistance and electrochemical performance of half cells (vs. Li/Li(+) ) as well as the rheological properties are affected by the content of a commercially available electroconductive carbon black [Ket...

Transforming from planar to three-dimensional lithium with flowable interphase for solid lithium metal batteries

Solid-state lithium (Li) metal batteries are prominent among next-generation energy storage technologies due to their significantly high energy density and reduced safety risks. Previously, solid electrolytes have been intensively studied and several materials with high ionic conductivity have been identified. However, there are still at least three obstacles before making the Li metal foil-bas...
