Graphene coating could help prevent lithium battery fires
Lithium batteries are what allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known, but so is their tendency to occasionally catch on fire - an occurrence known to battery researchers as "thermal runaway."
2D materials may enable EVs to get 500 miles on a single charge
Lithium-air batteries, which currently are still in the experimental stages of development, can store 10 times more energy than lithium-ion batteries, and they are much lighter. That said, lithium-air batteries could be even more efficient and provide more charge with the incorporation of advanced catalysts made from two-dimensional materials.
