When we connect a battery with AC Supply, then It will charge during positive half cycle and discharge during negative half cycle, because the Positive (+ve) half cycle cancel the negative (-ve) half cycle, so the average voltage or current in a complete cycle is Zero. So there is no chance to store AC in the Batteries.

Since the battery depends on its work on chemical reactions and produce electrons that accumulate in the cathode of the battery and is heading to the anode which we get the one-way stream can not be changed therefore can not get the AC, which requires switching polarity50 or60 times per second

Waow, the question by itself is very confusing. Are you an engineer, a technician or ... I am really sorry to be blunt like that, but the first courses taught in engineering, explains why. I know it has been a year since "Nehad Joujou" answer, but at least the last answer should be a follow up on it. First of All AC and DC defines the current and not batteries, hence the statement does not make sense. However, we can always imagine many scenarios. As an engineer, even the smallest idea can trigger  a set of thinking and analysis and speculation. If you are able to have a black box capable of storing energy and having an internal alternative current looping. What would be the need and benefit of such battery? is it viable financially? what would be its application? All of that knowing that from electronic design to high loads applications you have variable frequency generators that can readily provide AC from available battery design. Sorry for going out of subject. But those kind of questions should not be.

it's impossible to store AC bescouse need to do switing from50:60 times/s

Apart from its charge issue the Dc battery would be destroed if Ac is applied.

No , we can't because of battery polarity. By the use of an inverter we can  supply  ac loads.

If the aim is to supply AC load  with battery you simply need an ups which convert the stored power by an inverter to AC.

Nothing is impossible, right now we did not know how to store AC voltage and current, One day may we will store AC voltage also like in digital format or any other format, like an audio signal AC voltage samples can be stored in the individual cells and need to call back when it required.
