How green are they?

Battery may not be looked as green part. Progress in battery as related to real green technology is welcome. However, employing rare earth minerals and other minerals is not progress.

Battery is a temporary solution for "clean enviroment". However we need a good way to recycle them otherwise its no better than gas/oil.

"Battery is a temporary solution for "clean enviroment". However we need a good way to recycle them otherwise its no better than gas/oil."

Alex, what's the alternate solution for storage?

t.alex, agreed. It needs to be recycled otherwise it also uses natural resources. However, considering the energy usage by other power-sources for e.g. oil, gas, and coal, batteries are much better.

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.

Storage Efficency

"We know that battery capability, which is primarily defined using energy density by volume and by weight, is a critical factor in determining what we can expect of the units they power. Pundits at all levels of technical knowledge from near-zero to quite advanced keep reminding us of this obvious fact, and then opine on what they think will or should happen next."

Bill, energy domain/sector is an evergreen topic. Eventhough we are able to generate green or renewable energy, storage is a major concern. Mainly we are depending batteries for storage and as of now storage capacities are limited and around 60-70% are the efficiency of storage batteries. So more storage per cells has to be the motto for R&D in storage devices.

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.

Jacob, 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.

An untouched but critical topic

Bill, you have touched a topic which unfortunately has not been touched much by the tech-writers on internet which I think is due to the reason that they consider this topic too minute in aspect when considering the role of technology in growth of industries. However, you can realize its important if your phone/laptop/tablet is not charged at a time when urgent contact through email or internet apps becomes game-changer.

Energy packs of future
prabhakar_deosthali   10/30/2014 12:12:27 PM

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.

@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.

Another major area for Nobel prize

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.

@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.
