Enhancement of Lithium-Ion Conductivity in Liquid Crystalline Block Copolymer Electrolyte by Electric Field Alignment.

A block copolymer electrolyte (BCPE) with a liquid crystal and a lithium-ion conductive phase is investigated to assess the influence of an external applied electric field on the bulk morphology and the resulting electrochemical performance. For this purpose, the controlled synthesis of poly(10-[(4-cyano-4'-biphenyl)oxy] decatyl methacrylate)--(methoxy-poly(ethylene glycol) methacrylate--glycidyl methacrylate) [P(MALC)--P(PEGMA--GM)] block copolymer is performed by reversible addition-fragmentation transfer polymerization. The BCPE containing lithium bis(trifluoromethanesulfonyl)imide as the salt is drop-cast and crosslinked inside an alternating or direct current electric field.

One-pot synthesis of long-range aligned nanochannels for Li-ion transfer pathways.

Limited ionic conductivity () of solid polymer electrolytes (SPEs) is a bottleneck for their practical application. Constructing ordered ionic transfer highways is a prospective direction to promote . Here, we propose a straightforward one-pot synthesis strategy for the obtention of long-range aligned nanochannels, which is based on the evaporation of the solvent to induce the self-assembly of Pluronic® F127-resol micelles.

Practical Cell Design for PTMA-Based Organic Batteries: an Experimental and Modeling Study.

Poly(2,2,6,6-tetramethyl-1-piperidinyloxy methacrylate) (PTMA) is one of the most promising organic cathode materials thanks to its relatively high redox potential, good rate performance, and cycling stability. However, being a p-type material, PTMA-based batteries pose additional challenges compared to conventional lithium-ion systems due to the involvement of anions in the redox process. This study presents a comprehensive approach to optimize such batteries, addressing challenges in electrode design, scalability, and cost.
