Tesla’s ‘battery day’ next Tuesday could be ground-breaking for several industries

Tesla Inc’s (NASDAQ:TSLA) “Battery Day” event on Tuesday September 22 is likely to be the biggest item on the global business calendar in the coming week. 

Investors in the electric vehicle manufacturer and Musk’s army of fanboys and fangirls are charged up with excitement, while on the other side a battalion of Tesla bears reckon the whole thing could be Musk hype.

The South African-born billionaire said earlier this year that the event will “blow your mind” and more recently added that there will be “many exciting things” to see.

Only a very limited number of shareholders will be able to attend both of the events due to the current pandemic restrictions, with the Fremont, California-based company holding a lottery to select attendees.

Ramping up volumes and power

Back in a January earnings call, Musk explained that in order to ramp up production of the Tesla Model Y vehicle, introduce the new Cybertruck and launch its Semi electric truck, a lot more batteries would be needed.  

“The thing we’re going to be really focused on is increasing battery production capacity because that’s very fundamental – because if you don’t improve battery production capacity, then you end up just shifting unit volume from one product to another and you haven’t actually produced more electric vehicles,” Musk said. 

Tesla’s Model S has a 100 kWh battery pack giving it a range of around 400 miles, while the Porsche Taycan’s 93 kWh pack gives it 287 miles of range, while the Jaguar I-Pace has 90 kWh and a 292-mile range and the Mercedes EQC has an 85 kWh pack and a 259-mile range. 

Making the batteries even more efficient is a continued aim of all manufacturers, with Tesla’s looking to boosting its potential to do this with the acquisitions of battery technology businesses Maxwell and Hibar.

Analysts at UBS say the market consensus is for some significant announcements to be forthcoming, “cementing Tesla’s cost and technology lead for several more years”, leading the Swiss bank’s target price to be hiked to US$325 from US$160. 

While analyst Neil Wilson at Markets.com said many of Musk’s pronouncements on Twitter should be “taken with a pinch of salt”, he is among those expecting some industry-rocking news at the event, which follows straight after an annual stockholders’ meeting that starts at 13:30 Pacific Time.

To deliver on its EV promise, Wilson said, “Tesla needs to own the battery space” as “without this, it’s not so different to an OEM”. 

“My expectation is that Musk is about to announce if not a leap then a progression in battery technology that brings EV costs down to, or close to, traditional automobiles. It would be a surprise if Tesla were not able to say it has made further progress on batteries that are more energy dense and have a longer life.” 

Lower costs and higher density

The manufacture of battery cells of 400 Watt-hours per kilogram (Wh/kg) with a high cycle should be possible in volume within three to four years, Musk said in August, which would be a high improvement on the current 260 Wh/kg in the Tesla Model 3.

This indicates one area of Tesla’s potential battery improvement. 

An image on Tesla’s website promoting the annual shareholders meeting and Battery Day sparked more industry speculation, as it showed what appeared strands of silicon nanowire composed of tiny dots representing lithium. 

South Korean battery expert Park Chul-wan told Reuters that the image may hint at “silicon nanowire anode,” a breakthrough technology that can greatly increase battery density and cell life.

Tesla is also working with China’s leading battery producer CATL, which has signed a two-year deal to supply batteries to Tesla, and in other news claims it is developing a 1.2mln mile electric vehicle battery with a 16-year lifespan. 

Said Wilson: “If Tesla can both lower costs and increase battery energy density and life, it would be a significant step forward for the company and further cement its lead in the EV space. 

“However, given the recent rampant speculation on the stock and Musk’s capacity to somewhat overstate his case, there is a considerable risk of a buy-the-rumour, sell-the-fact trade.”

The UBS analysts say they expect a new battery cell technology, dry electrode design, to be at the core of the event, which would be likely to enable around a 50% higher energy density of up to 400 Wh/kg versus 260Wh/kg today, plus much better longevity – including the possibility of a million-mile battery.

They also estimate cell costs could be brought down to around US$70-80 per kWh over the next three or so years, saving US$2,300 per vehicle compared to today, with roughly a US$10-20 per kWh cost advantage versus competition.

Mining and chemicals sector impact

As many people eyeing the purchase of an electric vehicle have found, a major obstruction are the cars’ high cost relative to petrol-powered internal combustion engine vehicles, so reducing the cost of the battery would be give any car company a huge headstart over rivals.

Some speculate that Tesla may announcing a cobalt-free battery, using more of a less costly metal such as nickel and perhaps introducing manganese, which has implications for parts of the mining sector.

The UBS analysts agree there is potential for cobalt-free chemistry to be part of the announcement.

They noted that Johnson Matthey, which hosts its hydrogen seminar on Friday, the concept of a significant breakthrough in battery technology could “make it more difficult for JMAT to find a niche with its own ‘eLNO’ technology from 2023”.

What’s more it accelerate EV penetration, which could mean a more rapid displacement of Johnson Matthey’s diesel and gasoline catalysts technology, which make up around 60% of group profit.
