Summary
Waterborne polyurethanes (WPU) and poly(urethane-urea)s (WPUU) offer sustainable battery manufacturing. These materials enable advanced designs for lithium-ion and lithium metal batteries, balancing key performance properties.
Area of Science:
- Materials Science
- Electrochemistry
- Polymer Chemistry
Background:
- Waterborne polyurethane (WPU) and waterborne poly(urethane-urea) (WPUU) dispersions offer sustainable, water-based processing for rechargeable batteries.
- These polymers provide tunable adhesion and mechanical properties, suitable for various battery components beyond traditional binders and coatings.
Purpose of the Study:
- To review the fundamentals of WPU/WPUU chemistry, including building blocks, dispersion, morphology, and film formation.
- To analyze WPU/WPUU applications in batteries (electrode binders, separators, electrolytes) through a structure-processing-property lens.
- To identify key performance trade-offs and provide formulation guidelines for optimizing battery performance.
Main Methods:
- Literature review of WPU/WPUU fundamentals and battery applications.
- Analysis of structure-property relationships in WPU/WPUU materials for energy storage.
- Examination of formulation variables and their impact on performance.
Main Results:
- WPU/WPUU chemistries can be tailored for electrode binders, separator coatings, and polymer electrolytes in lithium-ion and lithium metal batteries.
- Key trade-offs exist between adhesion and electrolyte uptake, and ionic conductivity and mechanical strength.
- Formulation choices (segment selection, ionic design, molecular weight, crosslinking) significantly influence performance.
Conclusions:
- WPU/WPUU materials are versatile for advanced battery designs, requiring careful formulation to balance performance metrics.
- Future work should focus on stable interlayers, enhanced electrochemical properties, and specific design guidelines for lithium metal batteries (LMB).

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).

02:54Trends in Lattice Energy: Ion Size and Charge
26.7K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

01:23Urea Cycle
50.1K
The urea cycle describes how liver cells convert ammonia to urea. Ammonia is a toxic waste product of protein catabolism. Land animals must convert ammonia into the less toxic urea which can be safely eliminated by the kidneys through urine. Marine animals excrete ammonia directly, and the surrounding water dilutes the ammonia to safe levels.

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...
