a Discharge/charge profiles of Li | |KVO cell at 0.1 C for initial three cycles within 0.2–3.0 V at 30 °C (90%KVO: 5%Super P: 5%PVDF (polyvinylidene fluoride)). b Discharge/charge profiles of Li | |KVO half cell from 0.1 C to 10 C within 0.2 − 3.0 V at 30 °C. (80%KVO: 10%Super P: 10%PVDF) (c–e) Cyclability of Li | |KVO half cell after rate test at 30 °C. (80%KVO: 10%Super P: 10%PVDF) f The cycling stability of KVO is compared with that of other well-known long-life electrochemical energy-storage materials documented in prior studies (Refer to Supplementary Table 4). g Cyclability at 10 C over 8000 cycles at 60 °C (inset: Discharge/charge profiles from 0.1 C to 10 C at 60 °C, 80%KVO: 10%Super P: 10%PVDF). h Cyclability at 1 C over 2000 cycles at −10 °C (inset: Discharge/charge profiles from 0.1 C to 2 C at −10 °C, 80%KVO: 10%Super P: 10%PVDF). i Cyclability of KVO | |LiFePO4 full cell at 2 C under 30 °C over 1000 cycles, N/P ratio is 1.05, and the capacity is calculated based on mass of KVO (inset: Comparison of KVO | |LiFePO4 with Li4Ti5O12 | |LiFePO4 in terms of specific capacity, operating voltage, and specific energy).
