【CATL Self-Generating Anode】Sodium-Ion Battery: Energy Density Boundary: Self-generating anode, energy density increased by more than 50%. In terms of high energy density battery expansion, it pioneered a non-expanding anode. Cycle Life: High-energy SEI construction. Safety: Reconstructed electrolyte system, combined with surface electric field regulation and separator shield layer design, achieving high safety. Green Environmental Protection: Sodium-ion battery carbon emissions are up to 60% lower than lithium batteries, green and low-carbon throughout the life cycle. Energy retention rate at -40 degrees Celsius is greater than 90%, extreme cold as normal temperature. Energy density 175 Wh/kg.
