Next-Gen Battery Strategic Matrix: Solid-State vs Sodium-Ion

Investor-grade screening tool that rejects the “single winner” myth. Build a scenario (market + timeline + priorities) and see which tech wins: Solid-State (Premium King) vs Sodium-Ion (Cost King) — with LFP baseline.

Scoring uses your priority weights and maturity assumptions by year. 2025 treats Solid-State as lab/pilot-scale with low readiness.

FAQ

Does this tool claim a single winner technology?
No. The core purpose is to show segmentation: Solid-State tends to win on density-led premium markets, while Sodium-Ion wins on cost and supply chain resilience for space-tolerant markets.
Why is Solid-State treated as “lab/pilot-scale” in 2025?
In 2025, most solid-state programs are still scaling manufacturing, validating cycle life, and proving yield. The model applies a readiness penalty so the tool stays commercially honest.
Why include LFP as a baseline?
LFP is today’s market standard for many EV and stationary applications. A baseline keeps the analysis grounded: investors can see whether “next-gen” beats the incumbent on the axes that matter.
What does “projected system cost” mean?
It is a screening translation from cell cost ($/kWh) to a system-level estimate using multipliers that represent pack/BOP, safety, and integration complexity by application.
Why does Sodium-Ion score high on cold-weather performance?
Many sodium-ion chemistries have demonstrated relatively robust low-temperature behavior compared to some lithium-ion variants, which can be a key driver for micromobility, short-range EVs, and unheated stationary sites.
