This research provides insights into Tesla’s recently concluded “Battery Day”, the company’s battery business, and a competitive landscape with a focus on electric batteries. This spreadsheet has been populated with the details for 16 automotive companies.


Meeting Setup and Overview

  • The meeting scheduled for September 22, 2020, started 15 minutes late. This event was supposed to start at 4.30pm EST. This event had two major segments: The shareholder meeting and the “Battery Day” segment. Once the live transmission began, there were about a million times.160,000 people watching. By 8.30pm, this video was watched over
  • For those that attended the event physically, each person was assigned a Tesla car to follow the event proceedings, in order to adhere to the social distancing regulations. Each vehicle had a central screen where passengers could follow the event and a custom program. As stated in the previous research, participants would honk their cars to show support/respond to the presentation. This was an ingenious product-placement move by Tesla.

Environmental Impact

  • Tesla is also keen in ensuring that it reduces its impact on the environment. During this event, Tesla addressed the changes that the company will make to address the production of EV batteries. Traditional methods result in the production of excess waste or solvent. Addressing these issues is expensive and an energy-intensive process.
  • In his statement, Musk said the following: “We are a proud mining nation. Let’s continue that legacy by supplying environmentally-sustainable, ethically-sourced, high-quality battery minerals to the world, in addition to the value-added products that can be locally manufactured with these resources.”

Model S Plaid

  • In his announcement, Musk said that the Model S Plaid was now available on the company’s website and anyone interested could configure and place an order, with deliveries scheduled to begin towards the end of 2021. It is no doubt that this long awaited announcement would be the focal point, accompanied with its impressive specs. In his announcement, Musk was keen to elaborate on them: “a range of over 520 miles, a top speed of 200-plus mph, a 0-to-60-mph time of under 2 seconds, and a quarter-mile time of less than nine seconds.
  • This vehicle has a price tag that could be steep for many: $139,990.

Battery Design

  • Tesla’s new battery cell is referred to as the “biscuit tin”. This battery is cylindrical in design and uses lithium-ion chemistry. The larger cell canister has had the most significant change. This change increases the car’s range by 16% and a 5X increase in energy.
  • Tesla aims to produce its own EV batteries. The new “tabless” design will reduce the cost of production, which will bring down the overall cost of EVs.

Impact on Tesla’s Stock

  • Following Tesla’s “Battery Day,” the company experienced a drop in its stock. Although this is a tech-wide trend, it was evident that it generally disappointed investors. Following the Tuesday event, on Wednesday, stocks had dropped by more than 10 points.
  • Musk’s attempt to manage expectations for the event resulted in a five-point drop in its stock. On Monday, he posted on Twitter stating that “the battery announcement would affect long-term production of Tesla’s vehicles.”
  • It is speculated that the weak response to the announcements on “Battery Day” could be because Musk had already hinted the possibility of a $25,000 EV in 2018. This resulted in a $50 billion chop off its stock value, which continued to decline into the next day.

Cobalt Will Be Phased Out

  • Using cobalt in EV batteries has always had its challenges. It is a rare mineral that is difficult to mine. As a result, it is often done in an unethical way. For these reasons, Tesla has been looking for ways to eliminate this component.
  • Although Tesla uses significantly less cobalt than most companies in this industry, it may not be able to eliminate it completely. However, the company is taking steps toward phasing them out as it will also impact the cost of production.

New Manufacturing Plant

  • A new cathode plant in North America is also in the pipeline. Although the company is not sure which state it will be in, Musk says that the aim is to build a Gigafactory in every continent. This plant will utilize resources found in North America. By localizing this part of the production process, the company will have reduced the distance traveled by the battery components by 80%.



  • Tesla’s stock price is trading 10 times more in 2020, in comparison to 2019, with its shares surging over the $2,000 mark. The primary contributor to this stock price, aside from the overall investor excitement, is its battery business.

Competitive Landscape

  • This spreadsheet has been populated with insights surrounding EV battery production/usage in comparison with other car companies. This is a comparison between each company and Tesla. It is clear that most automotive companies do not produce/manufacture their own batteries: Most are outsourced from companies in China.
