How much do you know about Lithium Ion batteries? Can you pass this lithium-ion battery MCQ quiz? A lithium-ion battery or Li-ion battery is known as a type of rechargeable battery that is composed of cells in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. So, how much do you know about this battery? Let's find out with the quiz below.

Questions and Answers

1.

Select the odd one out 1,2 dimethoxy propane, Propylene carbonate, LiCl, LiBr, LiAlCl3, LiAlCl4
- A.
  
  1,2 demethoxy propane
- B.
  
  1,2 dimethoxy propane
- C.
  
  LiCl
- D.
  
  LiBr
- E.
  
  LiAlCl3
- F.
  
  LiAlCl4
Correct Answer(s)
A. 1,2 demethoxy propane
E. LiAlCl3

Explanation
The correct answer is 1,2 demethoxy propane and LiAlCl3. The other options are all compounds containing lithium (Li) or are related to lithium compounds. 1,2 demethoxy propane is the only option that does not contain lithium. LiAlCl3 is the only option that contains aluminum (Al) in addition to lithium (Li), while the other lithium options only contain lithium.

LiMnO2 is an example of:
- A.
  
  Lithium Ion battery
- B.
  
  Lithium Primary battery
- C.
  
  Lithium Secondary battery
- D.
  
  Secondary battery
Correct Answer(s)
A. Lithium Ion battery
B. Lithium Primary battery

Explanation
LiMnO2 is an example of both a Lithium Ion battery and a Lithium Primary battery. Lithium Ion batteries are rechargeable and commonly used in electronic devices. They have a high energy density and long cycle life. On the other hand, Lithium Primary batteries are non-rechargeable and often used in devices that require long-term power, such as medical devices or remote controls. LiMnO2 can be used in both types of batteries, making it a versatile material for energy storage.

Select the odd one out :
- A.
  
  LiPF6
- B.
  
  LiBr4
- C.
  
  LiClO3
- D.
  
  Esters
Correct Answer(s)
C. LiClO3
D. Esters

Explanation
The odd one out in this list is LiClO3 and Esters. The first three options are all chemical compounds that involve lithium (Li) combined with other elements or ions. LiPF6 is lithium hexafluorophosphate, LiBr4 is lithium tetrabromide, and LiClO3 is lithium chlorate. These are all inorganic compounds. On the other hand, Esters is a completely different category as it refers to a class of organic compounds that are derived from carboxylic acids. Therefore, LiClO3 and Esters are the odd ones out as they do not belong to the same category as the other options.

________ is the electrolyte used in Li-ion battery.
- A.
  
  Lithium-based gel
- B.
  
  Cobalt
- C.
  
  Sulfur dioxide
- D.
  
  None of these
Correct Answer
A. Lithium-based gel

Explanation
Lithium-based gel is the electrolyte used in Li-ion batteries. This gel electrolyte consists of lithium salts dissolved in a polymer matrix, which allows for the movement of lithium ions between the battery's electrodes during charging and discharging. This gel electrolyte offers several advantages over other electrolyte options, such as improved safety and stability, as well as better performance in terms of energy density and cycle life.

5.

Which, as shown below, avoids the direct contact of the positive as well as the negative plate in a lithium-ion battery?
- A.
  
  Electrolyte
- B.
  
  Load
- C.
  
  Rectifier
- D.
  
  Separator
Correct Answer
D. Separator

Explanation
The separator in a lithium-ion battery avoids direct contact between the positive and negative plates. This is important because direct contact could cause a short circuit, leading to the battery overheating or even exploding. The separator acts as a physical barrier between the plates, allowing ions to pass through while preventing the plates from touching each other. This ensures that the battery functions properly and safely.

6.

Which of the following is not a characteristic of a Lithium-ion battery?
- A.
  
  It contains nonaqueous electrolytes.
- B.
  
  It has a high cell voltage.
- C.
  
  It is operational over limited temperature change.
- D.
  
  It has a high energy density.
Correct Answer
C. It is operational over limited temperature change.

Explanation
A characteristic of a Lithium-ion battery is that it is operational over a wide temperature range, not limited temperature change. This means that Lithium-ion batteries can function effectively in both high and low temperature environments, making them suitable for various applications. The other options listed, such as containing nonaqueous electrolytes, having a high cell voltage, and possessing a high energy density, are all accurate characteristics of Lithium-ion batteries.

Find a,b,c, d from the below reaction: LiCoa + b ------> c + dLx
- A.
  
  A = 0₂ b = C6 c = Li_x-1CoO₂ d = C6
- B.
  
  A = 0₂ b = Mn c = Li_1-xCoO2 d = Mn
- C.
  
  A = O₂b = C6 C= Li_x-1CoO₂d = Mn
- D.
  
  None
Correct Answer
D. None
8.

X is safer than Y due to a certain structure that prevents the leaking of electrolytes. Identify X, Y, and the structure.Provided X and Y are certain types of Lithium-ion batteries.
- A.
  
  Primary, Secondary, Canned
- B.
  
  Secondary, Primary, Canned
- C.
  
  Primary, Secondary, Polymer
- D.
  
  Secondary, Primary, Polymer
Correct Answer
D. Secondary, Primary, Polymer

Explanation
Secondary lithium-ion batteries are safer than primary lithium-ion batteries due to the structure of a polymer electrolyte. The polymer electrolyte prevents the leaking of electrolytes, making secondary lithium-ion batteries more stable and less prone to thermal runaway reactions.

Cathode materials are generally constructed out of two general materials. One of these develops a pseudo tetrahedral structure that allows for two-dimensional lithium-ion diffusion. Guess the element.
- A.
  
  Lithium
- B.
  
  Oxygen
- C.
  
  Manganese
- D.
  
  Cobalt
Correct Answer
D. Cobalt

Explanation
Cathode materials are typically made up of two general materials. One of these materials, cobalt, forms a pseudo tetrahedral structure that enables two-dimensional diffusion of lithium ions. This suggests that cobalt is the element being referred to in the question.

In X, a key component is removed prior to activation. Id X and the component removed from it.
- A.
  
  Modern Battery, Anode
- B.
  
  Primary Battery, Cathode
- C.
  
  Reserve Battery, Electrolyte
- D.
  
  Secondary Battery, Salt Bridge
Correct Answer
C. Reserve Battery, Electrolyte

Explanation
In a reserve battery, the key component that is removed prior to activation is the electrolyte. The electrolyte is a substance that allows the flow of ions between the cathode and anode, enabling the battery to generate and store electrical energy. Removing the electrolyte prevents the battery from functioning until it is activated by reintroducing the electrolyte.
