Batteries will prove a high growth industry as green transformation accelerates

With lithium being a core component of the lithium-ion battery, the price of lithium is obviously playing a role in the cost of a battery pack. Lithium had a stable price during the year 2009-2014, but with the acceleration of electric vehicle production supply was tight and the price soared 220% from early 2015 to mid-2018 incentivizing huge investments into lithium mining and as supply has improved the price has collapsed 60% since the peak. The price of lithium is today only 18% more expensive than in early 2009 translating into a low 1.5% annualized compounding of prices. Lithium miners are not likely to capture the dominant part of the revenue stream from the revolution in batteries and as such lithium miner stocks are not expected in our view to be the most interesting play.

The cost of a lithium-ion battery pack has declined from almost $1,200/kWh in 2010 to $176 in 2018 and $156 in 2019 with BNEF (Bloomberg New Energy Finance) expecting the price to drop to $62/kWh in 2030. The cost reductions will come from economics of scale driven by electric vehicles and energy storage for renewable energy production and BNEF expects the global lithium-ion battery market to reach almost $120bn in annual revenue in 2030.

Electric vehicles the main demand driver for batteries are ongoing a revolution in the coming years. According to BNEF the number of electric vehicle models will reach 500 globally in 2022 and the sales volume will increase from 1.7mn in 2020 to 26mn in 2030 before reaching 54mn in 2040 representing 58% of all new car sales. These long-term forecasts tend to overshoot as technological progress is difficult to forecast and as such it could go much faster with regulatory forces adopted by many countries being the biggest factor. By 2040 the increase in electric vehicles will have displaced oil demand by 17.6mn barrels per day which is around 17% of pre-COVID-19 daily oil demand. The electricity demand in 2040 from electric vehicles is expected to ruse by 1,964 TWh translating to around 5% of global electricity demand.

China is centered around the production ramp-up but recent cost analyses show that Indonesia has a cost lead over China due to lower labour costs and easy access to nickel and cobalt (the two metals account for 22% of the battery pack costs) although it comes with a higher carbon intensity in the electricity used for battery production. Whether Indonesia can siege the moment the future will tell but as it is likely a technology race in advanced chemistry, we think China will come to dominate this industry.

Pure exposure to the battery and energy storage theme is difficult

The biggest problem with the battery theme is that many of the companies in this industry do not provide pure exposure to lithium-ion batteries. Many of the ETFs available on this theme are too broad based and some of them even have traditional carmakers in the basket or mining companies with little lithium exposure. We have made several decisions to filter the available stocks to a narrower and in our mind better exposure profile to lithium-ion batteries and the general trend in energy storage technologies.

Key for the 18 stocks in the table below are that they will benefit from the trends in mobile electrification and renewable energy which will get a major boost if Joe Biden wins the US election in November as we described last week in our research note Get ready for clean energy stocks if Biden wins.

Some of the companies in the list can always be debated. Tesla with only 6% of revenue coming from energy storage solutions is a stretch but on the other hand the company will benefit from cheaper lithium-ion batteries. We have added two companies that are normally not mentioned in this theme and those are Alfen and Umicore. Alfren, based in the Netherlands, was listed in 2018 and provides energy storage solutions but also charging stations for electric vehicles so the company again will benefit from cheaper and more accessible batteries fueling demand for electric vehicles. Umicore, based in Belgium, is big in recycling and the recycling of energy materials including lithium-ion batteries account for 16% of revenue. As the adoption of lithium-ion batteries accelerates recycling will grow in importance and this company seems to be best positioned to capture that trend.

Another observation by looking at the table is that the pure plays on lithium-ion batteries are mostly Chinese companies with Contemporary Amperex Technology Ltd (also called CATL) being the most interesting company as it just recently signed a big contract to supply Tesla with lithium-ion batteries for its electric vehicle production in China. CATL, Eve Energy and Sunwoda Electronic are not available on Saxo’s trading systems as these stocks are not listed on the main board but part of the ChiNext market which only certain institutional investors have access to.

Panasonic is one of those companies that are often mentioned as they were the first company to take a leap of faith in lithium-ion batteries for electric vehicles becoming Tesla’s main partner in the early stage. However, while it is a play on lithium-ion batteries the automotive batteries are only 6% of revenue and thus not the real driver of Panasonic’s share price. The company is big consumer electronics firm and could unlock a lot of shareholder value by splitting the automotive batteries segment out of Panasonic.

In our basket we have a couple of lithium miners as this is by far the biggest component in lithium-ion batteries. Nickel and cobalt are the two remaining dominant metals, but we have not added any miners in those two categories.

The average one-year revenue growth rate of these companies is 18% and the average EV/EBITDA valuation multiple is 35 which is almost three times that of the global equity market. This is obviously a steep price to pay for this trend but our general view on long-terms trend is that the market constantly undervalues compounding effects of multi decade trends. While the battery and energy storage industry could experience a setback in its valuation multiples our view is that the demand profile will remain strong for the next three decades as the world moves towards a less carbon-intensive economy fueled by electric vehicles and renewable energy.

The lithium-ion battery

The first commercial lithium-ion battery was released in 1991 by Sony and since undergone a rapid development in terms of energy density and costs. The entire history of the battery technology leading up to lithium-ion batteries is well illustrated on the visualcapitalist website. As the picture below shows the lithium-ion battery leads in runtime and energy density highlighting why this technology is leading the trend around mobile electrification and storing excess energy from renewable energy sources.

The idea of the lithium-ion battery goes all the way back to the 1970s where Stanley Whittingham, an English chemist working at Exxon Mobile, started exploring the ideas. Sony commercialized the idea and the laptop product started the mass demand for lithium-ion batteries. This battery technology is now crucial in the transition away from a carbon intensive economy and this was recognized last year when the Nobel Committee awarded the Nobel Prize in chemistry to the three scientists behind the battery technology.
