Which technology is making the most progress to become the next generation battery technology?

Avicenne Energy has been forecasting technology roadmaps and trends for nearly 30 years. The rechargeable battery market has moved from Lead Acid and NiMH to a majority Lithium-Ion with substantially higher energy density from its time of launch nearly 30 years. There has been a lot of hype over high silicon anodes, lithium metal, semi solid state, solid state and now we are seeing new technologies of sodium ion and Iron/Air. The discussion will cover the advances, technology, and business model changes along with early forecasts for technologies that have made significant progress.
