Tesla’s secret batteries could be a game changer. Technology could bring cost of electric vehicles in line with gasoline models.

  • The new Tesla batteries will be introduced in Model 3 sedans in China.
  • The new EV batteries will rely on innovations such as low-cobalt and cobalt-free battery chemistries, and the use of chemical additives, materials and coatings that will reduce internal stress and enable batteries to store more energy for longer periods.
  • The batteries should have second and third lives in the electric power grid.
  • The batteries should last for a million miles of use.
