What You'll Learn
The shift from ICE to electric vehicles
The shift from internal combustion engine (ICE) vehicles to electric vehicles (EVs) is well underway, with far-reaching implications for the automotive supply chain ecosystem. This transition is driven by a combination of factors, including technological advancements, environmental concerns, and government incentives. As the world moves towards electrification, the supply chain must adapt to meet the unique demands of EV production.
One of the key differences between ICE and EV supply chains is the complexity of their components. EVs have far fewer mechanical parts than ICE vehicles, which consist of thousands of individual components. In contrast, EVs are electronically driven, requiring semiconductors, electrical systems, power electronics, and thermal management systems. This shift from mechanical to electronic components has led to a more networked supply chain, with a diverse range of suppliers contributing to the EV manufacturing process.
The electrification supply chain has also brought about a change in the role of original equipment manufacturers (OEMs). In the traditional pyramid structure, OEMs sat at the top, with Tier 1, Tier 2, and Tier 3 suppliers below them. However, with the rise of EVs, the supply chain has evolved into a conduit-like structure, with OEMs collaborating more closely with their suppliers. This shift highlights the importance of strategic partnerships and a strong supply chain network to manage risks effectively.
To remain competitive, suppliers must develop new capabilities in software and advanced electronics. As the EV market grows, the demand for traditional ICE-related components will decrease, and suppliers will need to adapt their product offerings. This transition may pose financial challenges, especially for suppliers with substantial debt burdens, as they will need to invest in new technologies and potentially form joint ventures or partnerships to remain competitive.
The shift from ICE to EVs also has significant implications for raw material sourcing and battery technology. EVs require critical minerals such as cobalt, lithium, nickel, manganese, and graphite, which are predominantly mined in countries in the Global South. The supply of these minerals is subject to various risks, including sustainability challenges, political instability, and human rights concerns. Recycling and advancements in battery technology are proposed strategies to reduce the demand for raw materials and mitigate these risks.

Supply chain risks
The electric vehicle (EV) supply chain is an evolving network that encompasses the entire lifecycle of an EV, from raw material extraction to vehicle end-of-life management. The shift from internal combustion engine (ICE) vehicles to EVs brings significant changes to the supply chain, and suppliers must adapt to remain competitive.
One of the primary supply chain risks in the EV industry is the long lead time for electronics. The traditional automotive supply chain is driven by mechanical parts, and automotive manufacturers can rely on regional supplier networks to deliver components quickly. In contrast, the EV supply chain relies heavily on electronics, which have longer lead times of 6-12 months for semi-conductors alone. This lack of flexibility can disrupt assembly line fluidity and impact the ability of manufacturers to obtain components promptly.
Another risk is the competition from non-traditional suppliers. The shift to EVs increases the importance of software and advanced electronics, which may be provided by technology firms outside the traditional automotive supply chain. This creates new competition for legacy suppliers, particularly in the case of EV battery suppliers, who are also developing expertise in manufacturing electric powertrains. The rise of EVs will shrink the addressable market for traditional suppliers, and they may face a significant threat to their business if they cannot adapt to the changing landscape.
The EV supply chain is also vulnerable to disruptions due to its reliance on newer technologies and less-established supply networks. The risk of unforeseen events, such as fluctuations in demand or supply chain disruptions, is higher for EV supply chains than for the more resilient ICE supply chains.
To mitigate these risks, OEMs should future-proof their supply chains by partnering with suppliers who have the right sourcing strategies and capacity to meet flexible production requirements. Suppliers, on the other hand, should assess their ability to compete in the evolving market, considering their technological acumen, financial flexibility, and ability to provide software and advanced electronics.

The role of China
China is the world's largest automobile market and the largest new energy vehicle (NEV) market. In 2022, NEV ownership in China reached 13.1 million, with electric vehicles accounting for 79.78% (10.45 million). China has over 600,000 NEV-related enterprises, with 239,400 added in 2022 alone. The country's NEV market has been rapidly developing, with major industry players including BYD Auto, Tesla China, SAIC-GM-Wuling, Aion, and Changan Automobile, who together hold over 50% of the market share.
China holds a dominant position in the EV supply chain, particularly in the upstream stage, which involves the supply of raw materials and components for vehicle manufacturing. China accounts for 75% of global lithium-ion battery production and 70% of cathode capacity. The battery is a critical component of an EV, making up 40% of the vehicle's total price. China's prominent position in the upstream stage is due to its access to key minerals such as lithium and cobalt, which are concentrated in a few countries, including the Democratic Republic of Congo, Argentina, Chile, and Australia.
The country is also a major player in the midstream industry, which covers the vehicle manufacturing process. China has a robust manufacturing ecosystem for electric cars, commercial vehicles, and special-purpose vehicles. Supportive government policies, investments, and incentives have contributed to the rapid growth of the automotive manufacturing industry, making China a leading force in the global electric vehicle market. For example, the Chinese government offered generous subsidies that averaged $15,000 per vehicle in 2016 to encourage EV adoption.
The downstream segment of the EV supply chain includes charging services and after-market services, such as charging equipment infrastructure, automobile finance, insurance, trading, automobile repair and maintenance, and automobile dismantling and recycling.

The importance of raw materials
The EV supply chain is heavily reliant on the mining and refining of raw materials, which are then used in the manufacturing processes of batteries and other EV components. The battery alone accounts for 30-40% of the value of an electric vehicle. As the demand for EVs rises, so does the need for these raw materials. Cobalt, lithium, manganese, graphite, nickel, and other metals and materials are essential for battery production. For instance, cobalt is key to supporting the cathode in lithium-ion batteries, and nickel enhances battery range.
However, the supply of these critical minerals is concentrated in a handful of countries, leading to supply chain risks. For example, the Democratic Republic of Congo supplied around 70% of the world's cobalt in 2021. This concentration of supply can lead to sustainability challenges, political instability, and human rights or environmental concerns. The Ukraine-Russia war has also impacted the availability of raw materials, with the US and UK banning the import of aluminum, copper, and nickel from Russia.
To address these challenges, recycling batteries and advancements in battery technology have been proposed to reduce the demand for raw materials. Recycling lithium-ion batteries, in particular, can lower energy consumption. Additionally, OEMs and Tier 1s must ensure that their suppliers and partners have the right sourcing strategies and capacities to meet flexible production requirements.
In conclusion, the importance of raw materials in the EV supply chain is twofold. Firstly, they are essential for the production of EV batteries and components. Secondly, the availability and sustainable sourcing of these raw materials present significant challenges that must be addressed to secure the EV supply chain and meet the growing demand for EVs.
