摘要：

In this work, we developed an easy method to suppress the irreversible capacity (IC) observed in disordered carbons acting as electrode materials in lithium batteries by limiting the amount of Li inserted in the first discharge to different nominal capacities. This strategy is quite effective with carbons with a high IC. To suppress IC, the proposed method improves capacity retention and rate capabilities.
