| Solid-State | 250-500 | 800-1200 | 100-300 (projected) |
The table above illustrates the current standing of commonly used and emerging battery chemistries, highlighting their relative strengths and weaknesses. As technology improves, these numbers will inevitably shift, showing the dynamic nature of investment in battery development.
A crucial aspect of the “battery bet” is recognizing the intricate challenges associated with securing a reliable and sustainable supply chain. The production of batteries relies heavily on a limited number of critical minerals, including lithium, cobalt, nickel, and manganese. A significant portion of these resources is concentrated in a few countries, creating geopolitical vulnerabilities. For example, the Democratic Republic of Congo accounts for a substantial percentage of the world’s cobalt production, raising concerns about ethical sourcing and political instability. Furthermore, refining and processing these materials often require environmentally intensive processes, raising sustainability concerns. Diversifying supply chains, promoting responsible mining practices, and developing alternative battery chemistries that reduce reliance on critical minerals are all essential strategies for mitigating these risks. Companies making a large investment in batteries need to account for these complexities from the outset.
Recognizing the strategic importance of battery supply chains, many countries are actively encouraging domestic production and the establishment of battery recycling infrastructure.
