Sodium-ion batteries outperform lithium-ion in extreme cold, functioning at temperatures as low as -40°F with less risk of fire due to thermal runaway.
While sodium-ion batteries have a lower energy density compared to lithium-ion, they present a promising alternative for energy storage, especially in safer applications.
Srinivasan emphasizes skepticism towards claims of new technology, particularly highlighting the once-again lower energy density of sodium against lithium, depicting a hard truth in battery science.
The national labs are striving for sodium-ion batteries that can meet or exceed energy densities of lithium-ion solutions through innovative design and materials efficiency.
