Abstract

Although commercial lithium-ion batteries have been widely used in portable electronics and electric vehicles, they are still plagued by the uncontrollable dendritic lithium under extreme conditions. Herein, an efficient strategy is developed to produce a MXene-configured graphite via an electrostatic interaction between MXene and silane coupling agent-modified graphite. Typically, MXene layers are adhered onto the basal plane of graphite, with good preservation of the uncovered lateral edges of graphite, effectively strengthening the adsorption energy of Li+ and reducing the lithium nucleation energy barrier. Moreover, the MXene interface possesses good lattice compatibility with Li (110) plane, greatly promoting the homogeneous growth of Li along the preferable plane under extreme conditions. Even at -20 °C, Ah-level pouch cell with MXene-configured graphite electrode delivers a high capacity retention of 93% after 1200 cycles (273 Wh kg-1) at 1 C, exceeding lithium-ion batteries with bare graphite electrode (43% capacity retention, 191 Wh kg-1).

在极端条件下，mxene配置石墨实现长寿命锂离子电池。

尽管商用锂离子电池已广泛应用于便携式电子产品和电动汽车中，但在极端条件下仍存在不可控枝晶锂的问题。本文提出了一种通过MXene和硅烷偶联剂改性石墨之间的静电相互作用来制备MXene配置石墨的有效策略。通常，MXene层粘附在石墨基面上，很好地保存了石墨未覆盖的侧边缘，有效地增强了Li+的吸附能，降低了锂成核能垒。此外，MXene界面与Li（110）平面具有良好的晶格相容性，极大地促进了Li在极端条件下沿理想平面的均匀生长。即使在-20°C的温度下，配置mxene石墨电极的ah级袋状电池在1℃下1200次循环（273 Wh kg-1）后也能提供93%的高容量保持率，超过了未配置石墨电极的锂离子电池（43%的容量保持率，191 Wh kg-1）。
