  2. Sodium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Sodium-ion_battery

    Sodium-ion batteries ( NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion.

  3. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [ 1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [ 2] The terminal marked negative is the source of electrons that will ...

  6. Zinc–air battery - Wikipedia

    en.wikipedia.org/wiki/Zinc–air_battery

    A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate ( Zn ...

  7. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car ...

  8. Nickel–zinc battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–zinc_battery

    Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power. [6]

  9. Nanobatteries - Wikipedia

    en.wikipedia.org/wiki/Nanobatteries

    Nanobatteries are fabricated batteries employing technology at the nanoscale, particles that measure less than 100 nanometers or 10 −7 meters. [ 2][ 3] These batteries may be nano in size or may use nanotechnology in a macro scale battery. Nanoscale batteries can be combined to function as a macrobattery such as within a nanopore battery.
