The Imminent Battery Crisis: A Challenge for EV and Energy Sectors
Written on
The Battery Supply Dilemma
In the coming two decades, the production of batteries must expand by a staggering factor of 1,000 to satisfy soaring demand. While the chip shortage is expected to ease by 2023, a more pressing issue looms: a critical battery shortage that threatens the electric vehicle (EV) and energy sectors.
As noted by Steve Brearton in Pivot Magazine, the reasons behind this crisis are multifaceted, involving geopolitical tensions, economic factors, and a fair share of unfortunate events.
Section 1.1 The Origins of the Shortage
In 2019, restrictions imposed by the Trump Administration on tech exports to China prompted Chinese firms to stockpile chips. Simultaneously, the COVID-19 pandemic saw a surge in demand for home electronics, leading automakers to halt their orders. This shift directed semiconductor manufacturers toward other markets and higher-margin products. A catastrophic fire at a Japanese factory also eliminated crucial machinery, while extreme cold in Texas forced Samsung to pause production. The culmination of these factors created a supply-demand imbalance that experts predict will persist well into 2023.
Section 1.2 Future Battery Demand
Despite expectations to resolve semiconductor shortages and ramp up vehicle production in 2023, the forecast for battery demand is daunting. Transitioning from the production of small batteries for devices like smartphones to manufacturing massive batteries for cars and large-scale energy storage systems is essential. As renewable energy sources like solar and wind become more prevalent, the need for robust storage solutions will intensify.
According to Brian Wang, by 2028, the manufacturing pipeline for battery projects is anticipated to reach 1.45 TWh. The leading companies in this space, including LG Chem, CATL, BYD, Panasonic, and Tesla, produced only 160 GWh in 2019, indicating a necessity for a nine-fold increase in less than a decade.

Subsection 1.2.1 The Scale of Production Needed
Elon Musk recently stated in a TED interview that the world will require up to 300 TWh of installed capacity to transition transport, electricity, and heating into a sustainable energy framework, with Tesla projected to supply around 10% of that. Achieving such an ambitious target necessitates exponential growth in battery production capabilities.
Section 1.3 Challenges for Tesla
Tesla, being at the forefront of this transition, faces three significant hurdles:
- Enhancing 4680 Cell Manufacturing: Since unveiling this new battery format in September 2020, Tesla has been working to advance from prototype to full-scale production. Progress can already be observed at their GigaTexas facility, with a separate plant being established at GigaBerlin.
- Securing Raw Material Contracts: The mining sector presents the most significant constraints. Although the primary materials are abundant, establishing new mining operations is a complex and slow process, exacerbated by technical and regulatory challenges. Furthermore, mining activities typically generate high carbon emissions, necessitating a focus on sustainability.
- Rising Raw Material Prices: Geopolitical factors have driven up the costs of essential materials like nickel and lithium. As a result, battery prices have begun to increase for the first time in a decade, after a prolonged period of decline.
To combat these challenges, Tesla is diversifying its battery chemistries and form factors to maximize production capacity from both its factories and external suppliers. Nearly half of Tesla's vehicles produced in Q1 2022 featured lithium iron phosphate (LFP) batteries, which do not contain nickel or cobalt. The new factories in Austin and Berlin will be equipped to produce both the advanced 4680 cells and traditional 2170 cells, allowing for flexibility in battery sourcing.
Chapter 2 The Expanding Role of Batteries
Historically, lithium-ion batteries have been predominantly used in small electronics, but their application is evolving rapidly.

Section 2.1 Battery Electric Vehicles
The predominant application for these batteries is undoubtedly in electric vehicles. With an average battery size around 65 KWh, these are approximately 2,000 times larger than typical mobile phone batteries, necessitating a corresponding increase in raw materials. The anticipated demand for EVs will exert substantial pressure on battery supplies in the near future.
Section 2.2 Energy Storage Solutions
To meet carbon emissions goals, traditional fossil fuel power plants will need to be replaced by cleaner renewable energy sources. However, since these sources are intermittent, effective electricity storage solutions are essential. Tesla’s Megapack, for instance, provides energy storage capabilities of up to 3 MWh, encapsulated in a 23 x 5 feet (7 x 1.6 m) container weighing over 50,000 pounds (23 tons).
The industry is poised for intense competition among automotive manufacturers, utilities, and individual consumers to secure battery supplies for EVs and energy storage. This competition could hinder the reduction of battery prices, complicating the technology's immediate competitiveness.
Conclusion
Once the battery supply aligns with demand, it will pave the way for a cleaner, carbon-free energy landscape.
