Sodium-ion	100-150	300-500	80-150
Solid-state	300-500 (potential)	800-1200 (potential)	100-300 (potential)

The table above provides a comparative overview of the main battery technologies, highlighting their relative strengths and weaknesses. Note that these values are approximate and can vary depending on the specific chemistry and design of the battery. The "potential" values for solid-state batteries indicate the anticipated performance improvements once the technology matures.

Beyond Lithium: Exploring Alternative Chemistries

While lithium-ion remains dominant, the search for alternatives is intensifying. Concerns about lithium supply chain vulnerabilities, coupled with the desire for enhanced performance characteristics, are driving research into a diverse array of chemistries. Sodium-ion batteries, for example, utilize sodium – a much more abundant and cost-effective element than lithium. Although sodium-ion batteries generally have lower energy density than lithium-ion, they offer advantages in terms of cost and safety. Flow batteries represent another promising alternative, particularly for grid-scale energy storage. These batteries store energy in liquid electrolytes, allowing for independent scaling of power and energy capacity. This makes them well-suited for applications requiring long-duration storage, such as stabilizing the electricity grid with intermittent renewable energy sources. The diversification of battery chemistries reduces reliance on single materials and spreads the risk associated with a single technology failing to deliver.

Investing in these alternative chemistries is a crucial component of the broader "battery bet". While the potential rewards may be lower than those associated with a breakthrough in solid-state technology, the risk is also typically lower. These alternative chemistries often address specific niche applications or offer incremental improvements over existing technologies, making them more likely to achieve commercial success. Furthermore, the development of these alternatives can create a more resilient and sustainable battery supply chain, reducing dependence on geopolitically sensitive materials.

• Sodium-ion Batteries: A cost-effective alternative, leveraging abundant sodium resources.
