Simon Brooke"We have noted before that this is the fastest ride to zero-carbon; almost anyone can ride an e-bike for six miles under almost any conditions. If there were safe places to ride and secure places to park, then millions of car trips could be avoided, and millions of cars taken off the road"
Simon LucyYou want to switch your element of servitude to lithium?
Careful what you wish for.
@simon_lucy Who said that? Lithium is for a very brief period in history the most energy dense battery technology, but sodium batteries will be widely available within a few years.
Na-ion batteries in electronic devices, laptops included, were common in the 70's-90's, they lost overall capacity quickly had significant memory behaviour which also reduced capacity well within the life of the devices they powered.
Li-ion replaced them even though they were more expensive.
No doubt they can be improved but there are still problems.

Engineers reveal cause of key sodium-ion battery flaw | Cornell Chronicle
A new X-ray technique developed by Cornell engineers has revealed the cause of a long-identified flaw in sodium-ion batteries; a discovery that could prove to be a major step toward making sodium-ion as ubiquitous as lithium-ion.
