Manufacturing methods for high-energy, low-cost lithium manganese iron phosphate (LMFP) cathode active materials
Background LiFePO4 (LFP) cathode materials deliver excellent safety and cycle life but offer limited energy density, due to a low operating voltage (3.4V). Introducing manganese to form LiMnxFe1-xPO4 (LMFP) can boost specific energy 10% to 15% by raising the voltage up to about 3.8V, but the sluggish kinetics of Mn²⁺/³⁺ redox require small...

Super-sodiophilic seeds for dendrite‑free sodium metal batteries
Background As the demand for renewable energy sources and electric vehicles grows, there is a pressing need for efficient, sustainable, and cost-effective battery tech­nologies. Sodium-metal batteries (SMBs) show great promise for energy storage applications due to the natural abundance and low cost of sodium compared to lithium. However, SMBs...

Artificial SEI for a stable lithium metal anode in rechargeable batteries
Background Alkali metal anodes for rechargeable batteries suffer from dendrite formation, which subsequently causes electrical shorting and thermal runaway for the battery. A technology developed by researchers at The University of Texas at Austin stabilizes the anode-electrolyte interface such that stable alkali-metal plating/stripping is achieved...
