Well you’re probably thinking” Never heard of a sodium-ion battery doesn’t he mean lithium-ion?”
Well there has been progress with both batteries, the big deal here is that sodium-ion batteries have a potential to outperform the current standard that is the lithium-ion battery.
How does this affect migraineurs?
2 words: neural implants. If the battery capacity is significantly higher in sodium-ion batteries then perhaps migraine patients using occipital stimulators wouldn’t need to recharge it so often. Another thought I had and brought up with my neurologist is that perhaps if small enough these new high capacity batteries could be used in 2nd generation BION implants to increase its lifespan since it’s a single unit unlike the occipital stimulator which has a battery pack and leads. The devices may even become cheaper because lithium-ion batteries are more expensive and less stable than sodium-ion which is more abundant on our planet.
“The fascinating thing is that Na chemistry is much richer and has more variety than that of Li,” coauthor Kisuk Kang, Professor of Materials Science and Engineering at Seoul National University, told Phys.org. “This makes us believe that there will be unexplored Na battery electrodes out there that can far excel the current Li batteries.”
