Lithium-ion batteries have become a
mainstay of modern living because of their interesting physical and chemical
properties. Which of the following is not a
property of lithium-ion batteries? (A) Being rechargeable, (B) being
relatively light, (C) having long life spans, (D) storing large amounts of energy,
or (E) being inexpensive.
In this question, we want to know
which of the statements is incorrect when discussing the physical and chemical
properties of lithium-ion batteries. Lithium-ion batteries are a very
common rechargeable battery found in many portable electronics, such as cell phones
and laptop computers.
There are many different types of
lithium-ion batteries. Most of these lithium-ion batteries
are designed and manufactured to be relatively light due to their usage in mobile
devices. Therefore, being relatively light
is a property of lithium-ion batteries. Thus, option (B) cannot be the
answer to this question. The same is true for (C), having
long life spans, and (D), storing large amounts of energy.
The construction of lithium-ion
batteries means that it can operate as a secondary galvanic cell, where a secondary
galvanic cell is a type of electrochemical cell that can be run as both a galvanic
cell and as an electrolytic cell. This means that a secondary
galvanic cell is rechargeable. Therefore, option (A) is not the
answer to this question.
One of the few disadvantages
related to lithium-ion batteries is the fact that they are expensive. This is due to the fact that
lithium and cobalt are costly. From this data, we may deduce that
the answer choice that is not a property of lithium-ion batteries is (E), being
inexpensive.
