The current delivered by a battery is determined by its voltage and the resistance of the connected load. A battery will have an internal resistance that will limit the maximum current the battery will deliver into a short circuit and will cause the apparent voltage of the battery to decrease with higher currents. Thanks for your answer!!!
Provided by the Springer Nature SharedIt content-sharing initiative Aluminium-based battery technologies have been widely regarded as one of the most attractive options to drastically improve, and possibly replace, existing battery systems—mainly due to the possibility of achieving very high energy density with low cost.
This calculation takes all of the parameters that are important in evaluating battery performance into consideration such as discharge/charge capacities, current rate, number of cycles, capacity retention and coulombic efficiency.
You do not need to add any additional resistance. Also, 6 Ah is the C rating of the battery. The C and discharge rate is limited by the battery internal resistance, which leads to heating during charge and discharge. If you add cooling to the battery it can sustain a higher discharge rate, but you should consult the manufacturer.
Basically, given the discharge capacity (mAh g –1) and current rate (mA g –1), the discharge time for each cycle can be calculated, and then using the number of cycles and coulombic efficiency, the total operational time of the battery can be estimated.
Using Input Current Limiting to Extend Battery Life Despite constant advances in battery technology, producing a battery still involves multiple tradeoffs between different design goals such as size, self- discharge, or capacity to name a few.
