In order to decrease the effect of noisy environment on quantum teleportation, the scheme of quantum teleportation in the dephasing noisy environment based on the disentanglement-free state and quantum error-avoiding code was proposed. In this scheme, disentanglement-free atomic four quantum bit state was taken as the quantum entanglement channel, and the teleportated quantum information was encoded into two quantum bits. The results show the whole teleportation process is not affected by the noisy environment and the success probability for this teleportation scheme is 100%. This research is helpful to improve quality of the quantum communication
