Table 1 Initial discharge capacities of \(\mathrm {PTMA \,\vert \, LP57 \,\vert \, Li}\) coin cells prepared using the investigated PTMA samples I–IV, compared to corresponding number of spins per mg of sample and percentage of isolated radicals.
Sample | Number of spins per mg / x10\(^{18}\) | Isolated species / % | Initial \(C_{disc.}\) / mAh g\(^{-1}\) | SoH after 100 cycles / % |
|---|---|---|---|---|
I | 1.66 ± 0.10 | – | 96.0 | 94 |
II | 1.60 ± 0.16 | 0.3 | 99.1 | 93 |
III | 1.43 ± 0.08 | 1.0 | 78.4 | 86 |
IV | 1.41 ± 0.09 | 2.6 | 83.6 | 87 |
