According tomedia reports, many Tesla watchers are holding their breath for Tesla’s battery day — expected to be sometime in April. At the event, Tesla will announce new progress in building cheaper, denser, and longer-lasting batteries.
Now sources have told Electrek that more can be expected — tesla may be showing off a new domestic battery pack installed on Tesla cars.
Tesla is building a $100/kWh battery for their car in a secret project called Roadrunner. It is clear that the company is approaching the mass production phase of the new battery– a combination of technology developed by Jeff Dahn in Canada and dry electrode technology from Maxwell, as well as chemical technology developed in the United States. Tesla has been testing battery production at its fremont-based plant and has improved its process by transitioning its battery components from viscose to laser welding.
The $100/kWh price means its driving costs will be the same as for internal combustion engines, which is bound to provide a positive boost to sales of electric vehicles.
While Tesla hasn’t announced a specific date for battery day, it looks likely to be an exciting event.
