Bones May Be The Future Of Battery Design
  • Working on sodium batteries (potential alternative to lithium batteries), researchers discovered that mammalian bone design might stabilize their chemistry.
  • They created cathodes (electrodes that carry electrons) that are tough on the outside, and spongy on the inside.
  • Their proof-of-concept battery was able to maintain 91% capacity for over 10,000 charge cycles.
  • Lithium is explosive, and mining it is difficult and environmentally damaging, whereas sodium batteries are based on ubiquitous salt.
  • This is still just proof-of-concept, it gives hope, but sodium batteries are still a long way from being a viable replacement to lithium batteries.
