Diagramm from a Lithium-Ion Battery Model description

Hello, i just started using Simulink on Matlab so i don't know all the properties of this software. i've runned a Lithium-Ion battery model with the following parameter nominal voltage: 3.7V rated capacity: 2Ah and SOC:100%. And that is what's i got.

could someone explain to me the second diagramm? what is the meaning of the blue and red curves? What is their relationship with the Voltage? What is the meaning of this value(6.5A ,13A and 32.5A)? thank you
