Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").
Reset: Every 1–4 cycles the terminals must be shorted across a low-impedance shunt while running the electrolyte pump, to fully remove zinc from battery plates. [ 3 ] Low areal power: (<0.2 W/cm 2 ) during both charge and discharge, which increases the cost of power.
Zinc–air batteries have higher energy density than many other types of battery because atmospheric air is one of the battery reactants, in contrast to battery types that require a material such as manganese dioxide in combination with zinc. Energy density, when measured by weight (mass) is known as specific energy. The following table shows ...
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.

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.
