🧪 Blend OCV Tool

Imagine two water tanks side by side.

• Each tank represents one battery material.
• The shape of the tank tells us how much lithium it can hold at each "height".
• This shape is shown by the curve called dQ/dV (capacity per voltage).

In the plot you see:

• Left (green): tank of material A, scaled by its capacity fraction (q%).
• Right (yellow): tank of material B, scaled by (1-q%).
• The light-blue filling marks the current water level (voltage).

If we now put both tanks together, we get the blend tank.

• The blend curve (dark blue) is just the sum of both separate tanks.
• This shows how the mixture of A and B behaves as one electrode.
• Thin green and yellow lines remind you of the individual tanks.
• The thick dark-blue line shows the combined response.

The height of the water level is the voltage of the blend.

• As you slide the blend state of lithiation (θ_blend), the level moves up or down.
• At each level we can read:
• OCV of material A (green)
• OCV of material B (yellow)
• OCV of the blend (light gray blue, thick line)
• The dots show the current operating point for each.

Here comes the trickier part:

• The blend SoL is just one slider you control.
• But inside, each material has its own SoL (SoL A, SoL B).
• The curves show how SoL A and SoL B change as SoL Blend moves.
• The dashed line is a simple reference.

In summary:

• Top-left: the individual tanks.
• Bottom-left: the blend tank = A + B.
• Top-right: the voltage comes from the water level.
• Bottom-right: the hidden mapping between blend SoL and the two material SoLs.

By adjusting SoL Blend and q%, you can explore how different mixtures behave and see how electrode design shapes battery voltage.
