Experimental study demonstrates durable cycling in graphite-based lithium-ion batteries using mechanically interlocked gel electrolytes, indicating a pathway toward all-weather energy storage.

Key Points

To develop a mechanically interlocked gel polymer electrolyte network that overcomes graphite exfoliation caused by propylene carbonate co-intercalation while accelerating lithium-ion transport.
Designed a gel polymer electrolyte host containing mechanically interlocked networks functionalized with crown ether moieties to interact with propylene carbonate.
Fabricated and evaluated 1 Ah graphite||LiFePO4 pouch cells using the network electrolyte and LiPF6 across temperatures ranging from −20°C to 30°C.
Tested electrochemical compatibility with high-voltage LiNi0.8Co0.1Mn0.1O2 (NCM811) cathodes.
Crown ether units established dipole–dipole interactions with propylene carbonate, disrupting preferential Li+–PC coordination and suppressing destructive solvent co-intercalation.
The dynamic interlocked network enhanced polymer chain mobility, yielding rapid lithium-ion transport exceeding conventional gel polymer electrolytes.
Graphite||LiFePO4 1 Ah pouch cells sustained stable operation over 300 cycles and performed effectively from −20°C to 30°C while showing favorable compatibility with high-voltage NCM811 cathodes.
