Summary
Researchers developed a novel polymerization-induced heterogeneous configuration (PIHC) to prevent electrolyte shuttling in batteries. This innovative approach maintains high ionic conductivity at both room and low temperatures.
Area of Science:
- Electrochemistry
- Materials Science
- Polymer Chemistry
Background:
- Shuttling of active species is a major challenge in battery performance.
- Conventional electrolytes face limitations in stability and conductivity, especially at low temperatures.
Purpose of the Study:
- To introduce a polymerization-induced heterogeneous configuration (PIHC) for enhanced battery electrolytes.
- To spatially confine different electrolyte types within a single battery system.
Main Methods:
- Fabrication of a PIHC using a crosslinked fluoroacetonitrile (FAN)-based electrolyte at the cathode.
- Integration of a conventional ether electrolyte at the anode.
- Characterization of ionic conductivity at various temperatures.
Main Results:
- The PIHC effectively suppressed detrimental shuttling of active species.
- Ultrahigh ionic conductivity was maintained: 29.6 mS cm-1 at 25 °C.
- Significant ionic conductivity of 4.44 mS cm-1 was retained at -70 °C.
Conclusions:
- The PIHC strategy offers a promising solution for stable and high-performance batteries.
- This configuration enables electrolytes with distinct properties at the cathode and anode.
- The method ensures excellent ionic conductivity across a wide temperature range, crucial for advanced energy storage.

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...

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).

A conductor needs to be a component of a path that creates a closed loop or full circuit to have a continuous current flowing through it. A current starts to flow if an electric field is created inside an isolated conductor that is not part of a full circuit. The conductor quickly develops a net positive charge at one end and a net negative charge at the other. These charges generate an electric field opposite the direction of the applied electric field, which reduces the current. Eventually,...

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.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
