The practical importance of high (i.e. close to 1) transference numbers of the charge-shuttling ion (i.e. Li+ in lithium-ion batteries) is related to the fact, that in single-ion devices (such as lithium-ion batteries) electrolytes with the transfer number of the ion near 1, concentration gradients do not develop. A constant electrolyte ...
Liquid junction potential (shortly LJP) occurs when two solutions of electrolytes of different concentrations are in contact with each other. The more concentrated solution will have a tendency to diffuse into the comparatively less concentrated one.
In electrochemistry, exchange current density is a parameter used in the Tafel equation, Butler–Volmer equation and other electrochemical kinetics expressions. The Tafel equation describes the dependence of current for an electrolytic process to overpotential.
Lithium lanthanum zirconium oxide (LLZO, Li 7 La 3 Zr 2 O 12) or lithium lanthanum zirconate is a lithium-stuffed garnet material that is under investigation for its use in solid-state electrolytes in lithium-based battery technologies.
In theoretical chemistry, Specific ion Interaction Theory (SIT theory) is a theory used to estimate single-ion activity coefficients in electrolyte solutions at relatively high concentrations. [1] [2] It does so by taking into consideration interaction coefficients between the various ions present in solution.
The bonding between S 2-and Li + is weaker than that between O 2-and Li +, allowing for the Li + in the sulfide structure to be far more normal than its oxide counterparts. Ceramic thio-LISCON materials based on the chemical formula Li (4-x) Ge (1-x) P x S 4 are promising electrolyte materials, with ionic conductivities on the order of 10 −3 ...
The first term on the right-hand side is the Debye–Hückel term, with a constant, A, and the ionic strength I. β is an interaction coefficient and b the molality of the electrolyte. As the concentration decreases so the second term becomes less important until, at very low concentrations, the Debye-Hückel equation gives a satisfactory ...
Diabetes insipidus (DI) is a condition characterized by large amounts of dilute urine and increased thirst. [1] The amount of urine produced can be nearly 20 liters per day. [ 1 ] Reduction of fluid has little effect on the concentration of the urine. [ 1 ]
