Major Contributions
 

1. Revived the Li||CuCl₂ battery, proposed in the 1960s, with a highly fluorinated solvent-based electrolyte (HFSE, 1.0 M) that weakens Cu²⁺/Cu⁺–solvent interactions to suppress CuCl₂ dissolution and keep it in the solid state during reversible CuCl₂ ↔ CuCl ↔ Cu conversion.

2. The CuCl₂ cathode delivers a lithiation capacity of 399 mAh g⁻¹ and reversible delithiation capacity of 356 mAh g⁻¹ at 40 mA g⁻¹, and retains 293 mAh g⁻¹ after 40 cycles at 200 mA g⁻¹.

3. Cu K-edge XAS and in situ XRD revealed distinct intermediates, α-ZnS-type CuCl on discharge and β-ZnS-type CuCl on charge, and the chemistry was extended to reversible Na||CuCl₂ batteries with an analogous electrolyte.

主要貢獻
 

1. 以高度氟化溶劑電解液（HFSE，1.0 M）減弱 Cu²⁺/Cu⁺ 與溶劑的作用力，抑制 CuCl₂ 溶解，使其在 CuCl₂ ↔ CuCl ↔ Cu 可逆轉換中維持固態，重啟 1960 年代提出的 Li||CuCl₂ 電池。

2. CuCl₂ 正極在 40 mA g⁻¹ 下鋰化容量 399 mAh g⁻¹、可逆脫鋰容量 356 mAh g⁻¹；200 mA g⁻¹ 循環 40 圈後仍有 293 mAh g⁻¹。

3. Cu K 邊 X 光吸收光譜與臨場 XRD 揭示放電時生成 α-ZnS 型 CuCl、充電時生成 β-ZnS 型 CuCl 的中間相；以類似電解液將此化學延伸至可逆的 Na||CuCl₂ 電池。
