Two-dimensional polymer nanosheets as a high-performance organic anode for sodium-ion batteries

Abstract

Based on the conjugated system, the sodium 2-amino-4-thiazol-derived polymer (PATANa) exhibits rapid electron/ion transfer kinetics and limited solubility in the electrolyte for significantly enhanced cycling stability and rate capability of SIBs.

Insoluble Polyquinonyl Sulfide as High-Capacity Cathode Material for Magnesium Battery

“…For instance, Liao et al demonstrated that the 2,5-dimethoxy-1,4-benzoquinone (DMBQ), an organic cathode material for magnesium batteries, achieved a high initial discharge capacity of 226 mAh g –1 , but due to its dissolution in the electrolyte, the capacity decayed to 74 mAh g –1 after 30 cycles . Currently, several strategies have been proposed to mitigate dissolution, including salification, polymerization, − compositing with insoluble materials, , and electrolyte modification . For example, Cui et al employed the addition of LiCl to the all-phenyl complex electrolyte to inhibit the dissolution of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) and improve its cycling stability .…”
