Batteries - Potential Electrical Energy Storage
- Energy Storage
is a device consisting of one or more
with external connections provided to power
electrical devices such as flashlights, smartphones, and electric cars.
When a battery is supplying electric power
, its positive terminal is the
and its negative terminal is the
. The terminal marked
negative is the source of electrons
that when connected to an external
will flow and deliver energy to an external device. When a battery
is connected to an external circuit, electrolytes are able to move as ions
within, allowing the chemical reactions
to be completed at the separate
terminals and so deliver energy to the external circuit. It is the
movement of those ions
within the battery which allows current to flow out
of the battery to perform work. Historically the term "battery"
specifically referred to a device composed of multiple cells, however the
usage has evolved to additionally include devices composed of a single cell.

substance that produces an electrically conducting solution when dissolved
in a polar solvent, such as water. The dissolved electrolyte separates
into cations and anions, which disperse uniformly through the solvent.
, such a solution is neutral.
If an electric potential is applied to such a solution, the cations of the
solution are drawn to the electrode that has an abundance of electrons,
while the anions are drawn to the electrode that has a deficit of
electrons. The movement of anions and
in opposite directions
within the solution amounts to a current. This includes most soluble
salts, acids, and bases. Some gases, such as hydrogen chloride, under
conditions of high temperature or low pressure can also function as
electrolytes. Electrolyte solutions can also result from the dissolution
of some biological (e.g., DNA, polypeptides) and synthetic polymers (e.g.,
polystyrene sulfonate), termed "polyelectrolytes", which contain charged
functional groups. A substance that dissociates into ions in solution
acquires the capacity to conduct electricity. Sodium, potassium, chloride,
calcium, magnesium, and phosphate are examples of electrolytes, informally
known as "lytes". Capacitors
is the study of chemical processes
to move. This
movement of electrons is called electricity, which can be generated by
movements of electrons from one element to another in a reaction known as
an oxidation-reduction ("redox") reaction. It is the branch of
that studies the relationship between electricity, as a
measurable and quantitative phenomenon, and identifiable chemical change,
with either electricity considered an outcome of a particular
or vice versa. These reactions involve electric charges moving
between electrodes and an electrolyte (or ionic species in a solution).
Thus electrochemistry deals with the interaction between electrical energy
and chemical change. When a chemical reaction is caused by an externally
supplied current, as in electrolysis, or if an electric current is
produced by a spontaneous chemical reaction as in a battery, it is called
an electrochemical reaction. Chemical reactions
where electrons are
transferred directly between molecules and/or atoms are called
oxidation-reduction or (redox) reactions. In general, electrochemistry
describes the overall reactions when individual redox reactions are
separate but connected by an external electric circuit and an intervening

chemistry concerned with electrophysiological topics like cell

Electrolysis is commercially important as a stage in the separation of

is the potential of a chemical substance to undergo a
transformation through a chemical reaction to transform other chemical
substances. Examples include batteries, food, gasoline, and more. Breaking
or making of chemical bonds involves energy, which may be either absorbed
or evolved from a chemical system. Energy that can be released (or
absorbed) because of a reaction between a set of chemical substances is
equal to the difference between the energy content of the products and the
reactants, if the initial and final temperatures are the same. This change
in energy can be estimated from the bond energies of the various chemical
bonds in the reactants and products.Bio-Batteries

Electricity Storage Technology
is a passive two-terminal electrical
component that stores electrical energy in an electric field. The effect
of a capacitor is known as capacitance. While capacitance exists between
any two electrical conductors of a circuit in sufficiently close
proximity, a capacitor is specifically designed to provide and enhance
this effect for a variety of practical applications by consideration of
size, shape, and positioning of closely spaced conductors, and the
intervening dielectric material. A capacitor was therefore historically
first known as an electric condenser.
Electric Double-Layer Capacitor
capacitors which energy storage predominant is achieved by Double-layer
capacitance. In the past, all electrochemical capacitors were called
"double-layer capacitors". However, since some years it is known that
double-layer capacitors together with pseudocapacitors are part of a new
family of electrochemical capacitors called supercapacitors, also known
as ultracapacitors. Supercapacitors do not have a conventional solid
dielectric.The capacitance value of a supercapacitor is determined by two
storage principles: Double-layer capacitance – electrostatic storage of
the electrical energy achieved by separation of charge in a Helmholtz
double layer at the interface between the surface of a conductor electrode
and an electrolytic solution electrolyte. The separation of charge
distance in a double-layer is on the order of a few Ångströms (0.3–0.8 nm)
and is static in origin. Pseudocapacitance – Electrochemical storage of
the electrical energy, achieved by redox reactions electrosorption or
intercalation on the surface of the electrode by specifically adsorbed
ions that results in a reversible faradaic charge-transfer on the

charge and discharge cycles than rechargeable batteries.

Solar Energy Batteries
Tesla Motors Powerwall
is a lead-acid battery designed to be
regularly deeply discharged using most of its capacity. In contrast,
starter batteries (e.g. most automotive batteries) are designed to deliver
short, high-current bursts for cranking the engine, thus frequently
discharging only a small part of their capacity. While a deep-cycle
battery can be used as a starting battery, the lower "cranking current"
implies that an oversized battery may be required. A deep-cycle battery is
designed to discharge between 45% and 75% of its capacity, depending on
the manufacturer and the construction of the battery. Although these
batteries can be cycled down to 20% charge, the best lifespan vs cost
method is to keep the average cycle at about 45% discharge. There is an
indirect correlation between the depth of discharge of the battery, and
the number of charge and discharge cycles it can perform.

Depth of Discharge
(DOD) is an alternate method to indicate a
battery's state of charge (SOC). The DOD is the complement of SOC: as the
one increases, the other decreases. While the SOC units are percent points
(0% = empty; 100% = full), DOD can use Ah units (e.g.: 0 = full, 50 Ah
= empty) or percent points (100% = empty; 0% = full). As a battery may
actually have higher capacity than its nominal rating, it is possible for
the DOD value to exceed the full value (e.g.: 55 Ah or 110%),
something that is not possible when using state of charge. Not letting
your phone get below 50 percent can help extend its life? And not charging
to 100 percent too because being charged at 100 percent produces a small
amount of heat, and lithium-ion batteries hate heat.
. When the power source delivers current, the measured
voltage output is lower than the no-load voltage; the difference is the
voltage drop (the product of current and resistance) caused by the
internal resistance. The concept of internal resistance applies to all
kinds of electrical sources and is useful for analyzing many types of
Battery Management System

that manages a rechargeable battery (cell or battery pack), such as by
protecting the battery from operating outside its Safe Operating Area,
monitoring its state, calculating secondary data, reporting that data,
controlling its environment, authenticating it and / or balancing it. A
battery pack built together with a battery management system with an
external communication data bus is a smart battery pack. A smart battery
pack must be charged by a smart battery charger.

of electric current, in effect a form of battery, which use energy from a
radioactive source emitting beta particles (electrons). A common source
used is the hydrogen isotope, tritium. Unlike most nuclear power sources,
which use nuclear radiation to generate heat, which then is used to
generate electricity (thermoelectric and thermionic sources), betavoltaics
use a non-thermal conversion process; converting the electron-hole pairs
produced by the ionization trail of beta particles traversing a

being glucose, such as the glucose in human blood. When enzymes in human
bodies break down glucose, several electrons and protons are released.
Therefore, by using enzymes to break down glucose, bio-batteries directly
