Implication

Experimental study demonstrates enhanced cycling stability and thermal tolerance in lithium-ion pouch cells, highlighting a novel gel electrolyte design.

Key Points

To develop a gel polymer electrolyte based on mechanically interlocked networks that mitigates graphite anode degradation and overcomes sluggish lithium-ion transport in propylene carbonate solvents.
Synthesized a gel polymer electrolyte host containing a mechanically interlocked network with crown ether moieties to interact with propylene carbonate.
Assembled and evaluated 1 Ah graphite||LiFePO4 pouch cells using the gel electrolyte and LiPF6 across temperatures from −20°C to 30°C.
Assessed chemical and electrochemical compatibility with high-voltage LiNi0.8Co0.1Mn0.1O2 cathodes.
Crown ether moieties established dipole–dipole interactions with propylene carbonate, disrupting preferential Li+–solvent coordination and preventing graphite exfoliation.
The flexible mechanically interlocked framework enhanced polymer chain mobility, yielding rapid Li+ transport that surpassed conventional gel polymer electrolytes.
The 1 Ah pouch cells sustained stable operation over 300 cycles across −20°C to 30°C and demonstrated stable high-voltage cathode compatibility.
