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.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. The order of reactivity, as shown by the vigour of the reaction with water or the speed at which the metal surface tarnishes in air, appears to be Cs > K > Na > Li > alkaline earth metals,
An aqueous battery is an electric battery that uses a water-based solution as an electrolyte.The aqueous batteries are known since 1860s, do not have the energy density and cycle life required by the grid storage and electric vehicles, [1] but are considered safe, reliable and inexpensive in comparison with the lithium-ion ones.

Lithium is widely distributed in the lithosphere and mantle as a trace element in silicate minerals. [1] Lithium concentrations are highest in the upper continental and oceanic crusts. Chemical weathering at Earth’s surface dissolves lithium in primary minerals and releases it to rivers and ground waters.
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.
Silicon's large volume change (approximately 400% based on crystallographic densities) when lithium is inserted, along with high reactivity in the charged state, are obstacles to commercializing this type of anode. [4] Commercial battery anodes may have small amounts of silicon, boosting their performance slightly.
