C 60 to Modulate the Closed Pore Structures of Hard Carbon for High-Performance Sodium-Ion Batteries
Beijing University of Chemical Technology · Shandong Lianxing Energy Group (China)
Abstract
Hard carbon (HC) has emerged as a highly promising anode material for sodium-ion batteries (SIBs) attributed to its characteristic low-potential charge and discharge plateau. Recent studies have shown that the plateau capacity of HC mainly originates from the filling of the nanoscale closed pores by sodium. However, the precise design of the closed pore structure of HC remains a great challenge. Herein, C60 with a diameter of 0.7 nm is used to promote the formation of closed pores in phenolic resin-based HC. The spherical structure of C60 facilitates the oriented crystallization of graphitic microdomains within phenolic resin-based HC, thereby enhancing the uniformity of the closed pore structure of HC.…
