Multilayered alkali metal structures within graphene anodes unlocks 3X energy density, EV charging in minutes, dendrite mitigation for safety

"alkali metal ions (like lithium, sodium, potassium) sandwich ultradense 4-atom layer between sheets of graphene... nanochannels/ pores act as ion superhighways with 83% capacity retention after 3K high-speed cycles... metal deposits inside carbon frame rather than on surface, mitigating dendrites... potential carbon structures: graphite with atomic channels for deeper ion penetration, hard carbon with nanopores for sodium-ion storage, carbon spheres with mesochannels directing ions along optimal paths for stability"
