Why battery technology has not improved
In fact, many researchers believe energy storage will have to take an entirely new chemistry and new physical form, beyond the lithium-ion batteries that over the last decade have shoved aside.
FAQs about Why battery technology has not improved
Are lithium-ion batteries getting better?
Cold fusion is eternally 20 years away, and new battery technology is eternally five years away. That skepticism is understandable when a new battery design promises a revolution, but it risks missing the fact that batteries have gotten better. Lithium-ion batteries have reigned for a while now—that's true.
Are batteries getting better over the years?
The third important point: Batteries have been getting better over the decades. The reason we don't notice is that our devices have been getting faster, more powerful and more power-hungry at the same time. Heck, if you could put a modern iPhone battery into a 1995 phone, it'd probably go a year on a single charge.
