Enabling High‐Voltage Polymer‐Based Solid‐State Batteries Through Reinforcements with LiAlO2 Fillers

open access: yesAdvanced Energy Materials, EarlyView.
Polymer‐ceramic solid composite electrolytes with passive LiAlO2 fillers show remarkable improvements in Li‐ion conductivity in polycarbonates as compared to both non‐conductive Al2O3 and conductive Li7La3Zr2O12 counterparts. The exceptionally high transference numbers contribute to reversible and stable electrochemistry with Li‐metal electrodes and to

Elucidating the Impact of Functional Additives on the Structure and Ion Dynamics of Hybrid Solid Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
Using multinuclear and multiscale solid‐state NMR, the bulk and interfacial structures of a LiI‐integrated PEO‐LiTFSI‐Li6PS5Cl hybrid solid electrolytes are elucidated, revealing LiI's dual role in enhancing bulk Li‐ion mobility and facilitating Li‐ion diffusion across the organic/inorganic interfaces.

Solvent‐Phobic and Ionophilic Carboxylated Polythiophene Layer for Fluoride‐Rich Cathode Electrolyte Interphase

open access: yesAdvanced Energy Materials, EarlyView.
The organic mixed conductor, poly[3‐(potassium‐4‐butanoate)thiophene‐2,5‐diyl] (P3KBT) displays advantageous solvent‐phobic and ionophilic (SP‐IP) properties, such that when serving as an active material coating, a LiF‐rich Li2CO3‐limited cathode electrolyte interphase is created, improving electrode performance.

Effect of Propagating Dopant Reactivity on Lattice Oxygen Loss in LLZO Solid Electrolyte Contacted with Lithium Metal

open access: yesAdvanced Energy Materials, EarlyView.
The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Layer‐by‐Layer Processed Pseudo‐Bilayer Heterojunctions Advance the Performance of Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Layer‐by‐layer processed pseudo‐bilayer heterojunctions offer flexible processing strategies, optimized morphology, enhanced efficiency and stability, and scaling potential for organic solar cells. Abstract Recent progress in organic (semiconductor) solar cells (OSCs) has led to power conversion efficiencies (PCEs) reaching 20%, with predictions that ...
