How can higher current capacity be achieved in batteries?

Achieving a higher current capacity in batteries primarily involves connecting cells in parallel. When cells are connected in parallel, the total current capacity of the battery increases because the capacities of the individual cells add together. This configuration allows multiple pathways for the flow of current, which can handle greater loads and provide higher discharge rates.

For instance, if you have two cells, each rated at 1000 mAh when connected in parallel, the combined capacity becomes 2000 mAh. This increased capacity means the battery can deliver higher currents without depleting the charge quickly, which is particularly important in applications requiring bursts of energy or longer usage times between charges.

In contrast, connecting cells in series increases the voltage of the battery, not the current capacity. While using larger cells can also enhance the overall capacity, the method that specifically increases the battery's ability to deliver high current is the parallel configuration. Therefore, using cells in parallel is the most effective strategy for achieving higher current capacity in battery designs.
