Looks like Swatch think they are still 'in time' to jump on the bandwagon... Note the declared intent of their 51% affiliate Belenos to use vanadium vs. lithium - claims to have advantages (faster charging, lower weight)... http://www.carscoops.com/2017/01/swatch-developing-advanced-batteries.html?m=1 The article below (2.5 years old though) seems to support this... adding potential cost advantages... http://www.renewableenergyworld.com...anadium-in-energy-storage-its-no-contest.html Yet then... why has this been at the forefront of battery development in recent years? I must be missing something... Thoughts? Insights?
