Abstract:

The Li-rich manganese-based oxides (LRMO) with high operating voltage and large reversible capacities can demonstrate comprehensive advantages of intrinsic safety and high energy density when employed in all-solid-state lithium batteries (ASSLBs). However, severe interfacial incompatibility with solid electrolytes (SEs) arising from unstable lattice oxygen and sluggish Li⁺ ionic transport hinders their practical application. In this contribution, the gradient-modified structure containing S, Zr co-doping near-surface and amorphous Zr(SO₄)₂ coating is simultaneously established onto LRMO cathode by a one-step mechano-fusion process. The synergistic co-functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential. Besides, the amorphous Zr(SO₄)₂ coating evenly adhering onto LRMO bulk ensures long-term intimate contact with SEs to guarantee electrochemical activities and restrains interfacial parasitic reactions. Consequently, the optimized A-LRMO cathode exhibits a high discharge capacity of 292 mAh/g at 0.1 C and 81.8% capacity retention after 2000 cycles at 1 C. Pouch cells delivered an areal capacity of 8.5 mAh/cm² with >99.6% Coulombic efficiency. This gradient-modification strategy offers an effective pathway to improve interfacial stability and accelerate the practical application of LRMO-based ASSLBs.

Batteries and Fuel Cells

Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Metallic Solids

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Alkali Metals

Alkali Metals

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Molecular Comparison of Gases, Liquids, and Solids

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

Oxidation Numbers

Oxidation Numbers

In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Enzyme Kinetics

Enzyme Kinetics

Enzymes speed up reactions by lowering the activation energy of the reactants. The speed at which the enzyme turns reactants into products is called the rate of reaction. Several factors impact the rate of reaction, including the number of available reactants. Enzyme kinetics is the study of how an enzyme changes the rate of a reaction.
Scientists typically study enzyme kinetics with a fixed amount of enzyme in the controlled environment of a test tube. When more reactant, or substrate, is...
