There are more factors to consider, like size and weight (more low capacity cells will still weigh more, because there is dead weight associated with each cell - the external can, the wrapper, and the current collectors on the inside all weigh something and take up space, and that all adds up), as well as discharge capacity.

What is high Rate discharge battery? The high rate is representative of the charge and discharge capability of the lithium-ion polymer battery with respect to the ordinary rate. The high-rate battery is divided into a discharge rate and a charge rate, and "C" is used to indicate the ratio of the charge and discharge current of the battery, that is the rate. For example, a
Corrosion can induce higher internal resistance, reducing the battery''s capacity. Low Humidity: Dry air can increase the risk of static electricity, potentially discharging sensitive electronics if not managed well. For example, discharging a battery quickly (high current) reduces usable amp-hours compared to slow discharges.
However, even though our high-rate capacity was approximately three times below the low-rate C/A (~30 mAh cm −2) for the thickest electrodes, these cells still deliver ~10 mAh cm −2 within ~1
