Since battery capacity is given by Ampere-Hour (Ah), discharging a battery in a short time results a high current - with a value inversely proportional to the discharge time. This may increase the battery temperature and cause its damage.

Thank you :)  

High discharge and recharge rates may reduce the lifetime of the battery and increase its damage rate.

I agree with Mr. Gasim. However, everything depends on the battery technology, environment and your definition of the high current rate. For example lead-acid batteries have rather high specific thermal capacity because of the aqueous electrolyte. Therefore, it is not so easy to heat them up as it is the case of lithium-ion batteries. Furthermore, I have seen some test results which at least in case of lead-acid batteries showed a beneficial impact of the increased discharge current rate on expected cyclic lifetime. 

I can give some more details in this topic but you have to specify better your application and battery technology, which you are considering.

PS. You have to also have in mind that the battery capacity is also current dependant. It means that with the higher current rate you wont be able to discharge the rated capacity from the battery.

Thanks for this explanation. Actually I am trying to think about a scenario where i can draw current at high rate from battery and still i want my battery to be safely performing without deteriorating any of its feature. For having these requirements fulfilled at the same time, what are the essential possible features that the battery should have ??. 

It depends on the specification of your application. You have to answer yourself the following questions:

1) Is me application rather a high power (I guess high power) or high energy one

2) Is it stationary or mobile?

3) Which battery technologies (supercaps?) are considered?

4) Which current rates do I need?

5) Environment --> cooling? ambient temperature (or temperature range)? packaging?

6) Which calendric and cyclic life time is sufficient for my application?

Generally speaking for high power application the battery should have possibly low internal resistance. If high power capability is also needed at low temperatures than with li-ion you may experience some problems due to high resistance of the organic electrolytes at low temperatures. It is possible that in your application you dont need energy at all, than the best choice will be just taking some supercaps and not a battery.

As I said, you have to try to specify your application as well as possible and than you can look for some solutions. In the end the final system should be always a trade-off between price, expected life time and requirenments of the application.

PS. Sometimes if you see that your current rate is too high for some battery technology, if it is okay to have a bit higher price, you can just oversize the system so that the relative current (in C-rate) is smaller. 

Thank you very much.
