  2. Ion transport number - Wikipedia

    en.wikipedia.org/wiki/Ion_transport_number

    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 ...

  3. Solid-state electrolyte - Wikipedia

    en.wikipedia.org/wiki/Solid-state_electrolyte

    A solid-state electrolyte (SSE) is a solid ionic conductor and electron-insulating material and it is the characteristic component of the solid-state battery. It is useful for applications in electrical energy storage (EES) in substitution of the liquid electrolytes found in particular in lithium-ion battery.

  4. Separator (electricity) - Wikipedia

    en.wikipedia.org/wiki/Separator_(electricity)

    Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.

  5. Thin-film lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Thin-film_lithium-ion_battery

    In the thin-film lithium-ion battery, both electrodes are capable of reversible lithium insertion, thus forming a Li-ion transfer cell. In order to construct a thin film battery it is necessary to fabricate all the battery components, as an anode , a solid electrolyte , a cathode and current leads into multi-layered thin films by suitable ...

    en.wikipedia.org/wiki/Liquid_junction_potential

    The EMF of a concentration cell without transport is: E n t = R T F ln ⁡ a 2 a 1 {\displaystyle E_{\mathrm {nt} }={\frac {RT}{F}}\ln {\frac {a_{2}}{a_{1}}}} where a 1 {\displaystyle a_{1}} and a 2 {\displaystyle a_{2}} are activities of HCl in the two solutions, R {\displaystyle R} is the universal gas constant , T {\displaystyle T} is the ...

  7. Electrolytic cell - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_cell

    If this counter-electromotive force is increased, the cell becomes an electrolytic cell, and if it is decreased, the cell becomes a galvanic cell. [4]: 354 An electrolytic cell has three components: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is usually a solution of water or other solvents in which ions are ...

  9. Lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_battery

    A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
