Communication—Controlling Etching of Germanium through Surface Charge Manipulation J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-02-14 Joseph G. Wood, Surge Mitsyuk, Cassondra Brayfield, Arthur Carpenter, Charles E. Hunt, Klaus van Benthem
Potassium hydroxide (KOH) aqueous solutions can effectively etch germanium. Etch rates were determined in an electrolytic etch cell. Electrically isolated Ge wafers were subject to an etch rate of 1.45 ± 0.07 nm min−1, increasing to 12.6 ± 0.2 nm min−1 when grounded, 97 ± 2 nm min−1 when biased at −0.9 V, and 138 ± 2 nm min−1 with periodic biasing. Results suggest that the previously reported limited

Artificial Li3N SEI-Enforced Stable Cycling of Li Powder Composite Anode in Carbonate Electrolytes J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-02-14 Cyril Bubu Dzakpasu, Caleb Gyan-Barimah, Dongyoon Kang, Jihun Song, Dahee Jin, Jong-Sung Yu, Yong Min Lee
Lithium metal is considered one of the most attractive anode materials for next-generation batteries. However, the practical application of rechargeable Li-metal batteries has been hindered by the uncontrollable growth of Li dendrites and large volume changes during electrochemical cycling, leading to low Coulombic efficiency and safety concerns. This study reports a facile process of printing copper

A Comparative Study of Degradation Behaviors of LiFePO4, LiMn2O4, and LiNi0.8Mn0.1Co0.1O2 in Different Aqueous Electrolytes J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-02-14 Yuxin Zhang, Anyang Hu, Dong Hou, Gihan Kwon, Dawei Xia, Luxi Li, Feng Lin
Aqueous Li-ion batteries (ALIBs) are an important class of battery chemistries owing to the intrinsic non-flammability of aqueous electrolytes. However, water is detrimental to most cathode materials and could result in rapid cell failure. Identifying the degradation mechanisms and evaluating the pros and cons of different cathode materials are crucial to guide the materials selection and maximize

Suppressing the Growth of Dendrites On Ultrathin Lithium Metal Anodes by an Amide Electrolyte Additive J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-02-14 Thi Huong Pham, Van-Chuong Ho, Gyeong-Ho Son, Junyoung Mun, Jung-Gu Kim
The practical applications of high energy density lithium (Li) metal rechargeable batteries are hindered by the formation of lithium dendrites. Besides, using the thick Li anodes (typically 50 μm to 750 μm) provide more Li inventory than is needed in the cell as well as disappears the advantage of high energy density of Li metal over Li-ion batteries.Therefore, in this study, N-N-diallyl-2,2,2-trifluoroacetamide
