The IRA and the US Battery Supply Chain: Background and Key …
Lithium is arguably the most geopolitically sensitive material in the battery supply chain. Both the complexities of bringing on new lithium supply (with average project delays of 2–3 years) and limited substitution risk from alternative technologies reinforce this point. In short, lithium is key to unlocking net-zero targets.
A porous Li4SiO4 ceramic separator for lithium-ion batteries | Ionics
Using diatomite and lithium carbonate as raw materials, a porous Li4SiO4 ceramic separator is prepared by sintering. The separator has an abundant and uniform three-dimensional pore structure, excellent electrolyte wettability, and thermal stability. Lithium ions are migrated through the electrolyte and uniformly distributed in the three …
