Evidence Details
Ultrasonic-method evidence: source values include 1.4 nm, 0.96 nm, 1.56 nm, 1.51 nm, 1.49 nm. Entities: MMT-PVA.
The MMT was exfoliated into monolayers (only 0.96 nm) by intercalating PVA under ultrasound, followed by cross-linking with glutaraldehyde. The thickness of the nanocoating on the polypropylene separator, as determined using the pull-up method, is only 200-500 nm with excellent properties.
Additional source evidence: source values include 20 h, 120 h, 7900 h. Entities: MMT-PVA.
After 400 cycles, 90.4% of its capacity was still retained, and the capacity remained as high as 325.9 mA h g−1.
Capacity retention: 73.3%
Ultrasonic-method evidence: source mentions XH-2008DE.
