I see some potential in solar charging, @HM.  However, considering the impact of the entire chain really is critical.

"Recycling(especially as less Harmful to the Environment as possible) is super-critical "

Goog point.
Recycling awareness should be promoted and enforced at corporate as well as individual levels. Also, using adequate evalation metrics to assess recycling programs will help gauge the efficiency of such programs.

"one more thing I'd like to highlight is that in 30% of the usage times, I am facing a low battery alert. Portable battery pack is a good cover but ideally it shouldn't be required. Primary battery should serve the purpose."

Waqas, the issue with Smartphone and tablets are, most of the back ground processor and apps consumes lots of power continuously without the user knowledge. If you are able to stop that back end process, you can save energy to an extent.

"You have highlighted the core objective that should be setup by battery manufacturers and I am sure they realize that but it is true that results have not been very impressive when comparing them with other components of devices such as RAM, HDDs and processors."

Waqas, am not sure how we can compare batteries with RAM, HDD, processor etc, but there are some improvements happened in alkaline storage and power bank technology. The same is not scaled to normal battery technologies.

"The future enrgy packs ( not necessarily the conventional batteries using the electrochemical technique ) need to address these issues by some radical thinking in terms of material usage, energy conversion/reconversion and so on. "

@prabhakar: The way I see it, the batteries these days need to be given external charging and there's no on-the-go charging capabilities to charge with the application at hand. For instance, we need more work on how the phones and tablets can be charged using the motion, heat, solar power etc that can be obtained while the device is being used instead of it being plugged in separately.

@Himanshugupta: I agree with you. The innovation in battery power will indeed solve a lot of problems that we face today. It may give a quantum leap to the industry as you mentioned. However, the only way that can happen is when the innovation is something bizarre and out of the world not just a mere improvement in battery technology.

I know that this may be cliche but a quantum leap in battery or power storage will basically solve a lot of energy crisis that we are going towards. Majorly, all the renewable energy if stored at cheap then we will have major advancement in these fields. I think we should already announce a future nobel prize for anyone who can crack an ideal battery puzzle.

Waqas,

When one looks at it;Batteries are just a means to Store Energy and not a Source of Energy in and themselves-You will still need Coal,Oil,Gas,Hydro or in rare cases Solar /Geothermal/Wind/Biomass as Fuel to power the Machine in the first place and/or Charge the Battery.

So if your Battery is not recyclable then its not really-really helpful here.

Alex,

Have to agree wholeheartedly with your sentiments here.

As long as we are using Batteries made of Materials like Lithium and Cadmium we need to very careful about how one uses these Devices and especially how we dispose them off.

Recycling(especially as less Harmful to the Environment as possible) is super-critical here.

Energy packs of future

Basically the batteries are used in devices which are mobile   The cellphones, the vehicles, the laptops and finally the evolving EVs.

 

In all these devices the main performance criterion are 1. weight 2. energy density 3. recharge time and 4. cost.

The future enrgy packs ( not necessarily the conventional batteries using the electrochemical technique ) need to address these issues by some radical thinking in terms of material usage, energy conversion/reconversion and so on.
