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.

"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.

Alex, what's the alternate solution for storage?

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.

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.

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.

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.

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.

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.
