An algorithm to find a graded Projected Entangled-Pair State representationof the ground state wave functions is developed for translationally invariantstrongly correlated electronic systems on infinite-size lattices in two spatialdimensions. It is tested for the two-dimensional t-J model at and away fromhalf filling, with truncation dimensions up to 6. We are able to locate a lineof phase separation, which qualitatively agrees with the results based on thehigh-temperature expansions. We find that the model exhibits an extended s-wavesuperconductivity for J=0.4t at quarter filling. However, we emphasize that thecurrently accessible truncation dimensions are not large enough, so it isnecessary to incorporate the symmetry of the system into the algorithm, inorder to achieve results with higher precision.
