To summarize, because my that article does go on before getting to the "good" part: Removing the graphite anode from some batteries would make them cheaper and more efficient, but the downside is that they charge much more slowly. As a result this tech would be used only in auxiliary batteries. The second announcement is faster charging, although this isn't explained. The third announcement is the use of Sodium-ion batteries, although they admit this would require a different geometry, and therefore might be first used in trucks.
