BMW, Samsung SDI and Solid Power Launch Trilateral Program to Validate All‑Solid‑State EV Batteries

The effort moves the technology from lab samples to BMW demonstration vehicles via cells built by Samsung SDI using Solid Power’s sulfide electrolyte.

Overview

  • Under the agreement, Solid Power supplies a sulfide‑based solid electrolyte, Samsung SDI integrates the material into cell components and manufactures cells, and BMW develops modules and packs for testing.
  • The partners will assess cell performance against agreed parameters before installing qualified units in next‑generation BMW evaluation vehicles.
  • The collaboration formalizes and expands BMW’s solid‑state work with Solid Power dating to 2017 by adding Samsung SDI’s pilot‑line manufacturing capability established in 2023.
  • All‑solid‑state batteries offer potential gains in energy density and safety compared with conventional lithium‑ion cells, but real‑world validation, scaling and cost reduction remain prerequisites for commercialization.
  • Local media report that Samsung SDI targets 2027 for initial commercialization, while BMW and broader industry expectations often point toward around 2030 for wider adoption.
