The phrase "a stable capacity of" is correct and usable in written English.
It can be used when discussing the ability or potential of something to maintain a consistent level of performance or function over time.
Example: "The system has a stable capacity of processing data, ensuring reliable performance during peak hours."
Alternatives: "a consistent ability to" or "a reliable capacity for".
Is it a stable capacity of an individual?
The mesoporous lithium titanate exhibited a stable capacity of 160 mAh g−1 at 0.5 C.
The composite containing 60 wt.% of Si/Ni alloy exhibited a stable capacity of ∼780 mAh/g.
A stable capacity of 773 mAh g−1 can still be obtained even when the anode increases to 900 nm.
These hollow nanocomposites deliver a stable capacity of about 210 mA h g−1 at a high rate of 4.8C (1C denoted as 625 mA h g−1).
Figure 5c demonstrates the optimized shell of 25 nm performing, resulting in a stable capacity of 810 mAh g−1, even after 500 cycles.
Compared with the activated microporous carbon sphere/sulfur (AMCS/S) composite, the NAMCS/S composite with same sulfur loading of 64 wt% can deliver a higher initial capacity of 1004.6 mAh/g and a stable capacity retention of 79.1% after 100 cycles at 0.1 C rate as well as a remarkable Coulombic efficiency of 93% and relative low capacity decay of 0.2% per cycle.
Thus the architecture delivers a high area capacity of 0.511 mAh cm−2 at a current density of 0.2 mA cm−2 and a stable capacity retention of 83.3% after 200 cycles at 1 mA cm−2.
A remarkably stable capacity of 87 mAh g−1 was observed even after 1000 cycles with 100% coulombic efficiency at a current density of 200 mA g−1.
Among all, naphthalene diimide based dilithium carboxylate delivers a remarkably stable capacity of 134 mAh g⿿1 at 2.24 V vs. Li/Li+ over 125 cycles with a low polarization of 50 mV.
With this anode, we demonstrate a high stable capacity of 928 mAh g−1 based on the total mass of the composite at a current density of 500 mA g−1.
