2. Flow battery - Wikipedia

   en.wikipedia.org/wiki/Flow_battery

   A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.

3. Lithium-ion flow battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_flow_battery

   It uses a single tank and pump and reacts the LiS with lithium to produce power. The device operated for more than 2000 cycles without substantial degradation. [1] [3] When discharging, the lithium polysulfide absorbs lithium ions; releasing them when charging. [1] The demonstration device yielded energy density of 97 Wh/kg and 108 Wh/L with a ...

4. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   If rotary pumps are operated at high speeds, the fluids cause erosion, which eventually causes enlarged clearances that liquid can pass through, which reduces efficiency. Rotary positive-displacement pumps fall into five main types: Gear pumps – a simple type of rotary pump where the liquid is pushed around a pair of gears.

5. Fluid power - Wikipedia

   en.wikipedia.org/wiki/Fluid_power

   A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.

6. Electric-pump-fed engine - Wikipedia

   en.wikipedia.org/wiki/Electric-pump-fed_engine

   An electric cycle engine uses electric pumps to pressurize the propellants from a low-pressure fuel tank to high-pressure combustion chamber levels, generally from 0.2 to 0.3 MPa (29 to 44 psi) to 10 to 20 MPa (1,500 to 2,900 psi). The pumps are powered by an electric motor, with electricity from a battery bank.

7. Liquid-propellant rocket - Wikipedia

   en.wikipedia.org/wiki/Liquid-propellant_rocket

   An electric motor, generally a brushless DC electric motor, drives the pumps. The electric motor is powered by a battery pack. It is relatively simple to implement and reduces the complexity of the turbomachinery design, but at the expense of the extra dry mass of the battery pack. Example engine is the Rutherford designed and used by Rocket Lab.
