"Nothing here indicates a discharge rate."
In battery terminology, and this paper, charge/discharge rate is referred to as "C". Charging or discharging at 1C means a battery would be fully charged/discharged in 1 hour. A 100 Wh cell discharging at 1C would produce 100 W. Likewise, at 3C it would take 20 minutes and produce 300 W. At C/3, it would take 3 hours.
- rat9988 7y agoAre charge and discharge rate usually equal?
- hwillis 7y agoNo, but it is common to treat them as if they were. It depends on the chemistry as some are worse, but charging is slightly rougher than discharging. During charge the lithium ions need to intercalate into the graphite anode, which is slower than the reverse.
- falcolas 7y agoThat doesn’t give us any information on the capacity of the cells. Once we know the MAh of the cells, that gives us the output amperage, but without the capacity (or an amperage/watt value to derive the capacity), it’s a useless value.
- Reason077 7y agoThis information is given in the paper. Look for terms like capacity (mAh), specific energy (Wh/kg), and energy density (Wh/L).
