Novel dopamine-containing gel polymer electrolytes for Li-organic batteries
Cover of the Journal of Power Sources Advances
Published:
A new class of gel polymer electrolytes (GPEs) with dopamine-containing building blocks has been developed for safer and more efficient lithium–organic batteries. Unlike conventional liquid electrolytes, which are volatile, flammable, and prone to leakage, these novel GPEs combine safety with high performance. The dopamine-modified polymers achieve exceptional electrolyte uptake of 450% and provide high ionic conductivity (2.3 mS cm⁻¹ at 20 °C). These GPEs deliver a maximum discharge capacity of 59 mAh g-1 in Li//PTMA cells together with lower and more stable overpotentials compared to GPEs without dopamine-containing comonomer in Li//Li cells. By merging safety, efficiency, and sustainability, this approach represents a promising pathway toward next-generation organic radical batteries and green energy storage technologies.
Combining safety, efficiency, and sustainability, these electrolytes represent a promising approach for next-generation organic radical batteries and green energy storage solutions.
