“By partially replacing liquid electrolytes – the medium that carries electrical charge within a battery – with solid materials, semi-solid-state systems aim to improve safety durability and energy performance.”
SINGLE SOURCE
The claim describes the general scientific principle of semi-solid-state batteries (replacing liquid electrolytes with solids to improve performance). While the evidence confirms the *existence* of this technology and its goals (e.g., improving performance), the specific mechanism described—that *all* semi-solid-state systems improve safety, durability, and energy performance by *partially* replacing liquid electrolytes—is a general technical description not confirmed by multiple independent sources citing this specific mechanism.
