The Battery Battle

Toodles · 2025-08-26T08:52:57Z

Had I money that I wanted to invest in ‘The Battery of the Future’, (I haven’t, this is purely hypothetical and out of interest in others’ views please) where would I start investigating before investing? Almost daily, announcements are being made about new developments in rechargeable battery technology; with lithium out front in terms of of capacity / weight but somewhat less so in terms of safety and social responsibilities, other runners are beginning to look more and more promising as far as I can see. Aluminium (yes, good old British spelling please!) looking very promising and if Graphene manufacturing costs can be reduced, many new formulations look very promising. I suppose various types will be needed to satisfy different types of application but they all share the same interests in being cheaper, lighter, higher capacity and longer life, ability to charge more quickly, be socially acceptable etc. etc. etc. All these developments are very exciting but they make me think, (After having had fingers burnt when investing in a wind turbine project that collapsed when the company floundered.) which battery design is likely to flourish? Trying to back a winner in this race looks like being a very risky business! I also wonder why there is so much range anxiety for EV batteries now, after all, I think that a smaller battery could still outrun the average driver’s bladder constitution / safe driving duration and would result in a lighter vehicle and longer tyre life - just a muse on my behalf! Regards, Toodles.

Makes sense to me and we all had cases where even if a product stops being supported by a manufacturer, it is still usable.

When a product stops being sold, the manufacturer is still expected to develop firmware updates during their warranty period. Those updates could be made available for other users, even if their product warranty expired. Products usually include mechanisms to only allow installation of manufacturer updates.

And when a manufacturer really ends support for a model, communities like Home Assistant can be a lifeline to extend its use.
