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.
