Diversifying the supply chain for battery materials is becoming increasingly critical. Companies are exploring alternative sourcing locations and investing in recycling technologies to recover valuable materials from end-of-life batteries. Furthermore, research is focusing on reducing or eliminating the reliance on conflict minerals like cobalt. Direct Lithium Extraction (DLE) technologies are also gaining traction, promising a less environmentally damaging and more efficient way to extract lithium from brine resources. These efforts are not merely about mitigating risk; they represent a proactive approach to ensuring a sustainable and responsible battery supply chain.
| Lithium-ion | 150-250 | 500-1000 | 130-200 |
| Solid-state | 250-500 (potential) | 800-1200 (potential) | 100-300 (estimated) |
| Sodium-ion | 100-150 | 1000-2000 | 80-150 |
The table above illustrates the comparative advantages and disadvantages of different battery chemistries, highlighting the ongoing quest for improvements in energy density, cycle life, and cost. These figures are constantly evolving as technology advances, but they provide a snapshot of the current landscape.
