a battery which may last for ever
Re: a battery which may last for ever
Interesting development! There are many such developments happening in energy storage solutions but it will take at least a few years for it to be launched to the market and for pricing to come at par with currently available lithium storage solutions. For now, at least in Indian market LiFePO4 lithium batteries are most suitable and for some applications, flooded lead acid is still recommended particularly where zero maintenance battery isn't necessary.
