Solid Power v Stereax
SP = “There are many different flavors of solid-state technologies which are differentiated first and foremost by which solid ion-conducting materials you use. The most common solid electrolytes are polymers (organic) and sulfides (inorganic). Solid Power works exclusively in sulfide solid-state batteries. Sulfides also have the highest conductivity of any class of solid electrolyte, and furthermore, are relatively soft so they can be processed using traditional roll-to-roll type methods you would find in a lithium-ion gigafactory today.
Stereax = The Stereax® M250 is the first of a family of solid state,
rechargeable, thin film batteries developed by Ilika. It
contains no liquid or polymer components and is the only
solid state battery available without free lithium, either in
the charged or discharged state, making it moisture
resistant and appropriate for medical applications.
SP = These properties are what help ASSBs potentially have more energy density than regular Li-ion cells. Solid Power claims a minimum of 50 percent more but says it could double it
Stereax = Constant Voltage
Charging 4V; Time to 90% of nominal capacity
Operating temperature
SP= “Solid Power’s all-solid-state batteries are inherently more stable across a broad temperature range. While cooling elimination at the pack level is likely, we do expect ASSB packs to require pack heating, particularly for fast charging. We are currently working to lower our cell’s operational temperatures to match that of Li-ion, and have made significant improvements over the past quarter,
Stereax=Operating Temperature -20°C to 100°C °C
Based on the Above ,Seems Stereax is vastly superior
