Summary: A series of one-dimensional silica nanotubes (SNts) were synthesized by etching a rod-shaped nickel-hydrazine complex, and composite polymer electrolytes (CPEs) with high ionic conductivity were prepared by introducing the SNts and lithium salt into a poly(ethylene oxide) (PEO) matrix. The efficient transport pathway for lithium ions provided by the interconnected SNts in the composite led to a significant improvement in ionic conductivity compared to traditional electrolytes. The fabricated cell based on SNts showed good cyclability and rate capability, demonstrating the potential of SNts based CPEs for solid-state electrolytes and lithium metal batteries in the future.

Summary: Solid polymer electrolytes (SPEs) have gained increasing attention for all solid-state lithium battery (ASSLB) applications, with recent research suggesting that mechanical properties such as elasticity and toughness are also crucial in addition to polymer shear modulus. An innovative approach of introducing ultrahigh-molecular-weight poly(ethylene oxide) to form semi-interpenetrating network (s-IPN) SPEs has successfully decoupled toughness and modulus effects, leading to improved lithium symmetric cell cycling life and overall battery performance. This work highlights the importance of toughness as a key criterion in future SPE design.

Summary: Solid polymer electrolytes incorporating polyethylene oxide (PEO) have potential for improving the safety of lithium metal batteries (LMBs), although they suffer from low ionic conductivity. One solution to enhance the ionic conductivity is to add plasticizers such as succinonitrile (SN), but this negatively affects the cycle performances of LMBs. In this study, two-dimensional gamma-Al2O3 nanosheets are introduced into the PEO-SN matrix to facilitate the migration of lithium ions and improve the electrochemical properties of the electrolytes.

Summary: Conventional three-electrode systems used in electrochemical measurement require time-consuming and maintenance intensive procedures. In this study, a miniaturized printed circuit board (PCB) with the same metal (gold) for all three electrodes was used to simplify the design. The novel PCB-based same-metal three-electrode system showed comparable cyclic voltammetric profiles to conventional systems, but required fewer activation cycles and exhibited higher redox sensitivity and detection window.
