It’s also important to note that Dahn’s research was focusing on Nickel Manganese Cobalt Oxide (NMC) battery cells, which Tesla uses for its stationary storage products (Powerwall and Powerpack), and the first cell production at Gigafactory 1 was for those products.
Dahn explained that by increasing the lifetime of those batteries, Tesla is reducing the cost of delivered kWh for its residential and utility-scale projects. He gave examples of the costs at $0.23 per kWh for residential solar with storage and $0.139 per kWh for utility-scale, based on Tesla’s current projects:
For the batteries in its vehicles, Tesla uses Nickel Cobalt Aluminum Oxide (NCA) and Dahn said that they are also working on this chemistry. Tesla and Panasonic are planning to start production of battery cells for vehicles, starting with the Model 3, at Gigafactory 1 by June 2017.
He added that considering Tesla’s use of aluminum in its chassis, there’s no reason why both the cars and the batteries couldn’t last 20 years.
Hmmm... Both Cobalt based batteries... thanks for sharing the article @shades2
