Tesla Battery Day Innovations detail larger cylindrical EV cells with higher energy density, greater power, longer range, cobalt-free chemistry, automated manufacturing, battery recycling, and lower cost per kWh to enable an affordable electric car.
Inside the Issue
Tesla Battery Day innovations are new EV cells and methods to cut costs, extend range, and scale production.
Larger 4680 cylindrical cells with 5x energy, 6x power
~16% longer driving range per vehicle
Cobalt-free cathodes reduce material cost and risk
Highly automated, continuous-motion cell manufacturing
Recycling and $/kWh cuts target affordable EVs in ~3 years
Elon Musk described a new generation of electric vehicle batteries that will be more powerful, longer lasting, and half as expensive as the company’s current cells at Tesla’s “Battery Day”.
Tesla’s new larger cylindrical cells will provide five times more energy, six times more power and 16% greater driving range, Musk said, adding that full production is about three years away.
“We do not have an affordable car. That’s something we will have in the future. But we’ve got to get the cost of batteries down,” Musk said.
To help reduce cost, Musk said Tesla planned to recycle battery cells at its Nevada “gigafactory,” while reducing cobalt – one of the most expensive battery materials – to virtually zero. It also plans to manufacture its own battery cells at several highly automated factories around the world.
The automaker plans to produce the new cells via a highly automated, continuous-motion assembly process, according to Drew Baglino, Tesla senior vice-president of powertrain and energy engineering, a contrast with GM and Ford battery strategies in the broader market today.
Speaking at the event, during which Musk outlined plans to cut costs and reiterated a huge future for Tesla's energy business during the presentation, the CEO acknowledged that Tesla does not have its new battery design and manufacturing process fully complete.
The automaker’s shares slipped as Musk forecast the change could take three years. Tesla has frequently missed production targets.
Tesla expects to eventually be able to build as many as 20m electric vehicles a year, aligning with within-a-decade EV adoption outlooks cited by analysts. This year, the entire auto industry expects to deliver 80m cars globally.
At the opening of the event, which drew over 270,000 online viewers, Musk walked on stage as about 240 shareholders – each sitting in a Tesla Model 3 in the company parking lot – honked their car horns in approval.
As automakers shift from horsepower to kilowatts to comply with stricter environmental regulations amid an age of electric cars that appears ahead of schedule, investors are looking for evidence that Tesla can increase its lead in electrification technology over legacy automakers who generate most of their sales and profits from combustion-engine vehicles.
While average electric vehicle prices have decreased in recent years thanks to changes in battery composition and evidence that they are better for the planet and household budgets, they are still more expensive than conventional cars, with the battery estimated to make up a quarter to a third of an electric vehicle’s cost.
Some researchers estimate that price parity, or the point at which electric vehicles are equal in value to internal combustion cars, is reached when battery packs cost $100 per kilowatt hour (kWh), a potential inflection point for mass adoption.
Tesla’s battery packs cost $156 per kWh in 2019, according to electric vehicle consulting firm Cairn Energy Research Advisors, with some studies noting that EVs save money over time for consumers, which would put the cost of a 90-kWh pack at around $14,000.
Tesla is also building its own cell manufacturing facility at its new factory in Germany in addition to the new plant in Fremont.
