The Next-Gen Battery Race: Solid-State vs Sodium-Ion vs Lithium-Iron-Phosphate

Three battery technologies compete for the next decade. Solid-state: higher energy density, safer, but expensive and not yet mass-produced (Toyota, Samsung SDI leading). Sodium-ion: cheaper, no lithium/cobalt dependency, lower energy but sufficient for stationary storage (CATL, BYD developing). LFP: already dominant in China, safe and cheap, energy density improving (Tesla standard range). Each technology wins different use cases.
