3.1 Resource and sustainability concerns
High-nickel NMC batteries face significant challenges related to resource availability and sustainability. The materials required for these batteries, such as nickel, cobalt, and lithium, are finite and subject to supply chain risks. You may already know that the supply risk for lithium in China increased from medium-high to high between 2006 and 2022. Similarly, nickel and cobalt remain in the high-risk range, with predictions indicating continued risks over the next three years. These constraints stem from factors like environmental safety, low resource recovery rates, and high external dependencies.
Factor | Description |
|---|---|
Supply Risk Evolution | The supply risk of lithium resources in China evolved from medium-high to high from 2006 to 2022. |
High-Risk Range | Risks for manganese, nickel, and cobalt resources remain within the high-risk range. |
Future Predictions | Predictions indicate that lithium, manganese, nickel, and cobalt will continue to be in the high-risk range over the next three years. |
Significant Factors | Environmental safety, resource recovery rates, substitution rates, external dependencies, and production concentration are significant constraints on supply risks. |
Scholarly research highlights the impact of supply chain disruptions on critical metals like nickel and cobalt. For example, Zeng and Li (2015) found that such disruptions significantly affect pricing and availability. Recycling from end-of-life products, as noted by Fu et al. (2019), is essential for mitigating these risks. However, the dominance of a few countries in the supply chain, as Shi et al. (2022) observed, poses additional challenges. Ignoring potential disruptions in these regions could hinder effective risk management.

Fu et al. (2019); Rasmussen et al. (2019) | Recycling from end-of-life products is crucial for addressing supply chain risks. |
Shi et al. (2022) | A few countries dominate the supply chain, and ignoring potential disruptions in these countries can hinder effective risk management. |
Blengini et al. (2020) | The European Commission conducted a double-stage supply risk assessment to address these issues. |
To address these concerns, you can explore sustainable practices like improving recycling technologies and developing alternative materials. These efforts align with global sustainability goals and reduce dependency on high-risk resources.
3.2 Stability and safety issues
Stability and safety remain critical challenges in high-nickel NMC batteries. The high nickel content, while beneficial for energy density, introduces structural instability. This instability often leads to degradation mechanisms, such as the migration of transition metal ions caused by oxygen vacancies. These processes result in irreversible phase transitions, which degrade battery performance and compromise safety.
To enhance stability, researchers have developed strategies like bulk doping, surface coating, and gradient material preparation. Doping with high-valent cations, such as Ta5+ or W6+, refines the grain structure and reduces lattice strain. These methods improve structural integrity and mitigate side reactions, ensuring better performance over long cycles.
