A battery is essentially a galvanic cell, can
be also called a voltaic cell. Which is made
out of two half cells, a reduction half and
an oxidation half. The spontaneous
reaction that occurs provides the electric
current when the battery is on load. When
a load completes the circuit between the
two terminals of the battery there is a
production of electricity form the reactions
between the anode, cathode, and
electrolyte. In the anode an oxidation
reaction occurs where two or more ions
form the electrolyte combine with the
anode, this forming a compound and so
releasing one or more electrons. At the
same time the cathode goes through a
reduction reaction. Where the ions and the
free electrons from the solution combine to
form compounds. The reaction from the
anode creates electrons and the cathode
absorbs them. This reaction will continue
to occur until one or both of the electrodes
run out of the substances needed for the
reaction to happen. Brain, M. (n.d.).
A rechargeable battery is able to reverse
this process when it is plugged into an
electrical outlet. The material that
normally losses electron and oxidizes
during discharge gains electrons, and the
other material gives ups the electrons

Impact On Society
Rechargeable batteries in device have really
changed the way people live. It allows for people
to take portable devices such as phones, laptops,
or other devices with them. It allows us to stay
more connected even when we are outside. It
also has a great positive impact on society. Using
rechargeable batteries decrease the impact of
global warming up to 25%. By using these there
is a great increase of portable devices, and so we
can more use of the devices. Go Green. (n.d.).

Cost: They are more economically efficient
because they can be used many times
over. Moore, C. (n.d.).
Better performance: Rechargeable
batteries always perform at peek voltage
while disposable ones slowly decrease in
voltage Electronics Warehouse. (n.d.).
Earth Friendly: They produce less waste
because they can be recharged, and use
less
Less storage: Having rechargeable
batteries you need less batteries because
they can be re-used.
Lower voltage performance: Battery
technology has greatly improved but some
still perform at a lower voltage than normal
batteries. Some rechargeable batteries
perform at 1.2 V while non-rechargeable ones
perform at 1.5 V Electronics Warehouse.

Slow recharge time: it can take anywhere
from 2-15 hours to recharge battery
depending on the battery Electronics
Warehouse. (n.d.).
A rechargeable battery can vary on charge
depending on its capacity and the device it is
powering. Typically a battery can last 2-9 hours
depending on use. To maximize the life span of
the battery it is better to keep the battery
temperature low and battery charge at about
20%-80%.This is best way to maximize usage
and keeping the battery life span the longest. But
to increase to life span to most possible it would
best to keep the battery between 40%-60% and
the temperature at about 40 C.
Disposability
For the disposing of batteries so that it does not
negatively impact the environment, it would be
best to go to a retailer that would be able to
recycle batteries properly. To keep the toxics
maintained and so it does not affect people in the
household these safe measures should be taken.
Keep away from flammable place as it may cause
on fire, do not open as there is toxic inside. If
kept in house they should be recycled Ministry
