Researchers have also long been chasing lithium-air batteries that could realize a huge jump in energy density. And beyond lithium, there are other entirely different chemistries in development out there. At some point, one of them should click for one application or another.
Lithium-ion or not, an explosion of grid-scale battery installations is coming as prices continue to fall. The nascent art of lithium-ion battery recycling is also sure to mature and expand, improving the sustainability of these batteries by recovering and resetting their chemical building blocks.
Adopt cold-fusion-like skepticism of any of these future-looking statements as you please, but today’s batteries aren’t those of 20 or even 10 years ago. The same thing is bound to be true in another 10 years—even if that progress doesn’t come in a single, giant leap with global fanfare.
