The American, more famous for her headline-making fashion statements than her tennis, recovered from a set down to win 5-7 6-3 6-2.
Two summers ago Mattek-Sands was ranked in the top 30 but last year came a slump that dropped her outside 200 in the rankings.
She was still ranked that low in February but began her climb back with a run to the final of the tournament in Kuala Lumpur and has really hit form on the clay.
The 28-year-old came through qualifying in Stuttgart last month and reached the semi-finals, beating last year's French Open runner-up Sara Errani on the way, and this win over the sixth seed means she has already equalled her best run at Roland Garros.
Li, who beat Francesca Schiavone in the final two years ago, was the player who ended Mattek-Sands' run in Stuttgart but she was out-hit today.
The American served for the match for the first time at 5-0 in the decider only for Li to pull two games back, but her comeback ended there.
The match finished in heavy rain having been twice disrupted, but Li was left scratching her head for answers.
"If I knew for sure, I would not lose seven games in a row. This is very tough conditions, going back to the court three times," Li said.
"But for both players it's the same, so I should find out what happened and talk to myself and also talk to team to see what happened."
Li admitted the level of Mattek-Sands' play had shocked her, saying: "I was a little bit surprised the way she's hitting on the court. Well done to her. Good luck for her, as well."
Third seed Victoria Azarenka reached the third round with a 6-4 6-3 victory over Annika Beck that was not as straightforward as the scoreline suggested.
Azarenka, the Australian Open champion, won five of the first six games against German teenager Beck only to then lose three in a row.
Beck, last year's junior champion at Roland Garros, had two chances to level at 5-5 but Azarenka dug deep to win the set.
Seventh seed Petra Kvitova is also through to the third round thanks to a 6-4 6-3 victory over China's Shuai Peng.
