• Face-to-face covalent bridging in-between 2D-nanosheets/graphene heterostructure was constructed by intentionally prebonding of laser-manufactured amorphous and metastable nanoparticles on graphene.

• The consecutive bonding enables the robust anchoring of ultrathin SnS₂ nanosheets on graphene with huge covalent coupling area as well as spontaneous charge transfer in-between the heterostructure.

• Such laser-manufactured heterostructure is capable of guaranteeing high-flux electron/ion migration and structural integrity upon cycling, thus contributing to the unprecedented Na-storage capability.

激光衍生的界面限制使二维 SnS2 在石墨烯上的平面生长成为可能，用于钠储存中的高通量电子/离子桥接

• 二维纳米片/石墨烯异质结构之间的面对面共价桥接是通过在石墨烯上有意预键合激光制造的非晶和亚稳态纳米粒子而构建的。

• 连续键合使得超薄 SnS ₂纳米片能够牢固地锚定在石墨烯上，具有巨大的共价耦合区域以及异质结构之间的自发电荷转移。

• 这种激光制造的异质结构能够保证循环时的高通量电子/离子迁移和结构完整性，从而有助于实现前所未有的钠储存能力。
