Rate capability battery
The capacity of the battery for each of these various discharge rates can be calculated as discussed above. The rated capacity for lead-acid batteries is usually specified at the 8-, 10-, or 20-hour rates (C/8, C/10, C/20). The capacity of a battery or accumulator is the amount of energy stored according to specific temperature, charge and discharge current value and time of charge or discharge. Rating capacity and C-rate C-rate is used to scale the charge and discharge current of a battery. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes. This number is usually given with the number of hours at which the rate was taken. The Peukert constant generally ranges from 1.1 to 1.3. For Absorbent Glass Mat (AGM) batteries, the number is usually between 1.05 and 1.15. It can range from 1.1 to 1.25 for gel batteries, and it can generally be 1.2 to 1.6 for flooded batteries. At a higher current rate of 500 mA/g the capacity and reversibility is merely affected. Importantly, the reversibility is independent of the FEC concentration in the range of 10 vol% and 20 vol%. For both FEC concentrations a capacity loss of 30–40% after 100 cycles is observed independent of the current rate.

Although almost all works devoted to the LIB electrode materials examine the rate capability somehow, there are growing efforts in the quest for high rate capability LIBs. Charge Rate: current applied to a cell to restore its capacity. Charge rate is usually expressed in terms of the cell's C Rate. Charge retention - Residual capacity after a period of storage of a fully charged battery. Charge, state of - The capacity remaining in a cell or battery.
