  2. Solid-state battery - Wikipedia

    en.wikipedia.org/wiki/Solid-state_battery

    A solid-state battery (SSB) is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. [1] Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries. [2]

  3. Alkali-metal thermal to electric converter - Wikipedia

    en.wikipedia.org/wiki/Alkali-metal_thermal_to...

    The converter is based on the electrolyte used in the sodium–sulfur battery, sodium beta″-alumina, a crystalline phase of somewhat variable composition containing aluminum oxide, Al 2 O 3, and sodium oxide, Na 2 O, in a nominal ratio of 5:1, and a small amount of the oxide of a small-cation metal, usually lithium or magnesium, which ...

  4. Equivalent circuit model for Li-ion cells - Wikipedia

    en.wikipedia.org/wiki/Equivalent_circuit_model...

    The equivalent circuit model (ECM) is a common lumped-element model for Lithium-ion battery cells. [ 1 ] [ 2 ] [ 3 ] The ECM simulates the terminal voltage dynamics of a Li-ion cell through an equivalent electrical network composed passive elements, such as resistors and capacitors , and a voltage generator .

    Shaped so that it can be inserted into a battery compartment only one way. No longer made by Duracell, nor listed in its official website, but still stocked as of 28 February 2017 by some re-sellers. Typical mass: 1.1 oz (31 g). [142] Disposable equivalent of the Nikon EN-EL5 Li-ion rechargeable camera battery. [141] 7R31: Kodak K 7R31 538 4 ...

  6. Superheterodyne receiver - Wikipedia

    en.wikipedia.org/wiki/Superheterodyne_receiver

    A 5-tube superheterodyne receiver manufactured by Toshiba circa 1955 Superheterodyne transistor radio circuit circa 1975. A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency.

  7. Direct-conversion receiver - Wikipedia

    en.wikipedia.org/wiki/Direct-conversion_receiver

    A direct-conversion receiver (DCR), also known as a homodyne, synchrodyne, zero intermediate frequency or zero-IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is identical to, or very close to the carrier frequency of the intended signal.

  8. Biobattery - Wikipedia

    en.wikipedia.org/wiki/Biobattery

    Like any battery, bio-batteries consist of an anode, cathode, separator, and electrolyte with each component layered on top of another. Anodes and cathodes are the positive and negative areas on a battery that allow electrons to flow in and out. The anode is located at the top of the battery and the cathode is located at the bottom of the battery.

  9. Boost converter - Wikipedia

    en.wikipedia.org/wiki/Boost_converter

    A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input to its output . It is a class of switched-mode power supply (SMPS) containing at least two semiconductors, a diode and a transistor , and at least one energy storage element: a capacitor , inductor , or the two in ...
