The "zero excess" lithium–metal battery cell concept, in which the pristine negative electrode consists only of current collector, while all lithium is present positive active material, promises substantial improvements energy density. However, achievement stable cycling for more than just a few cycles requires careful design and adjustment components─especially collector at electrode. Herein, we provide comparative investigation commercial, polycrystalline copper foil, characterized by...
Lithium–metal batteries employing solid electrolytes (ceramics or polymers) could surpass the energy and power densities of current state-of-the-art lithium-ion batteries. Unfortunately, ceramic electrolyte/electrode interfaces suffer from poor interfacial contact, polymer show insufficient ionic conductivities for practical uses. Composite electrolytes, comprised mixtures mitigate these challenges by combining high conductivity with good contact. However, it is imperative to understand...
“Zero-excess” lithium-metal batteries represent a very promising next-generation battery concept, enabling extremely high energy densities. However, lithium metal deposition is often non-uniform and accompanied by severe side reactions with the electrolyte, limiting Coulombic efficiency and, thus, density cycle life. To address this issue, we introduced thin polymer-based artificial interphase at negative electrode. The influence of on deposition, generally occurring electrode, was evaluated...
