First fully rechargeable carbon dioxide battery with carbon neutrality
Lithium-carbon dioxide batteries are attractive energy storage systems because they have a specific energy density that is more than seven times greater than commonly used lithium-ion batteries. However, until now, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy.

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.
