Positioning for an electric vehicle future

As we have written previously, it seems reasonable to expect that the rate of adoption of electric vehicles (EVs) will increase markedly in years to come. Within a handful of years, it is thought that advancing technology will make EVs competitive with internal combustion engine (ICE) vehicles on a lifecycle cost basis, and at that point they should start to become a meaningful fraction of total vehicle sales. Looking further, due to their very low operating costs, EVs lend themselves to Transport as a Service (TaaS) applications, and the use of autonomous electric vehicles in these applications has the potential to offer dramatically lower transport costs compared with current alternatives.

Given these developing themes, it is natural to consider how an investor might position themselves to benefit.  On the face of it, a very appealing story can be constructed around investing in things for which EV adoption should drive increasing demand.  In Australia, an obvious candidate would be to invest in companies that will provide the raw materials needed to produce batteries for the growing EV fleet.

However, while people are naturally attracted to a narrative like this, it is important to recognise that a simple narrative often falls short when it comes to building a convincing investment thesis.  To be fair, if you were among the first to recognise that EVs were going to play a large role in the future of transport, then at that time you would have held an investable insight.  However, being early to identify an emerging trend is a genuine feat of insight, and by the time the trend is apparent to a large section of the investing universe, the opportunity may have already run its course.

When this happens, it’s important to be a little wary of the simple narrative, and to consider whether it contains real insight that hasn’t already been incorporated into asset prices.  Let’s explore some of the issues using the example of electric vehicle battery raw materials.

By way of background, today’s electric vehicle battery technology is focused on a lithium-ion chemistry.  These batteries have three main components:

  • a cathode, which typically contains lithium, but in varying combinations with nickel, cobalt and/or manganese, with different manufacturers focusing on different formulations;
  • an electrolyte, which contains lithium salts; and
  • an anode, typically made of graphite.

So, there are a few raw materials candidates need to consider, but the ones that are important in most of today’s lithium-ion batteries are lithium (commonly supplied in the form of lithium carbonate) and graphite. Different types of lithium-ion battery use different amounts of each commodity, but with an estimated 30 per cent+ of lithium production already finding its way into batteries, this is clearly an important part of the total demand picture for lithium. For graphite, the numbers are less dramatic, with less than 20 per cent of graphite production estimated to go to battery applications, but clearly with potential for this percentage to grow over time.

On the face of it then, growing demand for EVs should drive growing demand for these commodities and, all else being equal, good returns for the producers of these commodities.  However, there are a few places in which this thesis could come unstuck.

The first is the potential for a supply response. A period of high prices and strong returns for a commodity typically encourages investment in new supply which drives prices and returns back to more normal levels.  In the near term, some industry participants are pointing to an inadequate supply response based on an assessment of new projects currently planned to come into production, and that is certainly a positive, but for how long might this be sustained?

It would be helpful for the thesis if there were significant obstacles to increasing production. For example, if reserves of lithium and graphite were scarce, and large amounts of capital and complex infrastructure were needed to bring them into production, that would clearly hinder the supply response to the benefit of incumbents.

However, in the case of both lithium and graphite, it is not clear that any of these obstacles present major challenges.  Compared with ‘bulk’ commodities like iron ore, lithium and graphite have a high value per tonne, which makes production and logistics less challenging, and neither is particularly scarce. A fun fact about lithium is that it can be extracted from sea water (although other sources are generally cheaper).

Over time then, it seems likely that high prices for these materials should encourage a supply response that will bring prices back down and drive returns towards the cost of capital. It is difficult to forecast the timing of this, but it is important to have a view on it.  A company valuation typically rests heavily on cashflows that will be received more than 5-10 years down the track, and the outlook for these more distant cashflows needs to be considered with some care.

There is another way in which our investment thesis could come unstuck, and that relates to changes in battery technology. For example, last year, Elon Musk of Tesla responded to a question about lithium supply by saying:

“Our cells should be called Nickel-Graphite, because primarily the cathode is nickel and the anode side is graphite with silicon oxide… [there’s] a little bit of lithium in there, but it’s like the salt on the salad,”

In other words, Tesla doesn’t expect to consume a great deal of lithium given its choice of battery design. If lithium prices should be sustained at high levels for an extended period, it doesn’t take much imagination to see other manufacturers also moving to battery designs that avoid lithium. In other words, as well as a supply response, there is scope for a demand response to bring high commodity prices back to more comfortable levels for end users.  Given that raw materials make up a significant part of total battery costs, manufacturers will be keen to get this right.

The demand issue goes further than this.  Continued technological development directed at battery efficiency could have dramatic impacts.  For example, graphite is not necessarily the best anode material to use in a lithium-ion battery.  In theory, silicon anodes offer an energy capacity ten times that of graphite anodes, but to date, practical problems of expansion and cracking have prevented their widespread adoption. As you might expect, researchers are working hard on solving these problems, and if these efforts are successful, the demand picture for graphite could change significantly. Further, this is only one of many avenues of battery research that may give rise to different battery chemistries to the ones we see today.

To pull all of this together, there is without doubt an intuitively appealing narrative about growing demand for raw materials like lithium and graphite as EVs become more widely adopted, and the same can be said for other materials like nickel, cobalt and manganese.  However, that narrative should not be confused with a well-considered investment thesis.

The latter requires a critical assessment of future supply and demand dynamics, and how these play into commodity prices and valuations. The bad news is that in this case, that is very difficult to get right. Supply and demand dynamics are unpredictable at the best of times, and in this case the challenge is compounded by evolving technology.  Faced with these types of uncertainties, the right response could be to put your hand up and “too hard”.

The good news is that you don’t have to solve every problem the equity market throws at you to be successful.  If the future of one part of the market is inherently unknowable, and your knowledge and skill afford you some insight into another part of the market, then focus your attention there instead.

You can still put money into the battery raw materials theme if so inclined, but do it with the knowledge that this is may be more speculation than investment.

  1. Bruce, electric vehicles and autonomous vehicles are 2 separate issues. Personally they would have to pry my cold dead hands from the steering wheel and gear stick before I give up my sportscar for a self-driving Googlemobile that sticks to 40kph. Many people ENJOY driving and will not want to relinquish human control to machines.
    No smog? Not if our power stations generate it…
    As for accidents, a self driving Tesla killed a man this year or last year.

    • Don’t make the mistake of taking your own personal preference for driving and extrapolating to the rest of the population. The transition will be slow and incremental. It begins with advanced forms of cruise control. Then comes automatic braking if you’re too slow to step on them yourself yourself. On and on it continues, replacing and improving individual driving tasks step by step, Until eventually we can take our hands off the steering wheel and fully succumb to our autonomous chauffeur!

      It is my belief that autonomous vehicles will absolutely become ubiquitous – it’s just a matter of when.

      Remember, many people in cities don’t even own a car. They don’t need to in a world of choked traffic, high maintenance and storage/parking costs. Moreover, love of driving is probably a generational thing; anecdotally I’ve noticed that attitudes to driving are far less “romantic” for younger people. I suspect this trend will continue.

      As for accidents, you’ve managed to cite one instance! The annual road toll in Australia alone is $1,000. And none of this considers non-fatal accidents, which are the vast majority. The propensity of automation to significantly reduce this number is pretty undeniable at this point.

  2. Better to focus on what will change. No petrol stations. No tankers. No smog. Autonomous vechicles will mean no highway patrol cops. No breath testing. No P platers. Few accidents. Low insurance. Ride share models to replace ownership. No smash repairers. No mechanics. A fewer number of auto electricians. No drivers licence. Oldies will not need to give up mobility.

  3. Thank you for your article.

    I think you have missed another key element of electric vehicles being rare earths or more specifically neodymium praseodymium (NDPR), a key component of magnets in electric motors.

    There are a number of Asx listed companies in his space, but only one that is actually producing and processing the ore which is Lynas (LYC).

    Now I know you don’t like mining companies, but I think Lynas is more accurately described as a chemical company and has the opportunity to move further up the supply chain and partner with magnet makers.

    I would be interested in your views (positive and negative) in relation to this commodity.

  4. Any comment on the cobalt side of the supply equation? To me that seems to be the more difficult commodity to secure ready supply given its current geogra

  5. Did that years ago invested in one, and the shares rapidly went down. Still holding them wont give you a name or code but they process the stuff in Malaysia! Still ever hopeful they will eventually rise and no good selling them as someone else could get a bargain. So why did I buy I thought the same as Tim!
