Section 1

What is the primary difference between electrochemical energy storage and electrical energy storage?

• Type of reaction involved

• Amount of energy stored

• Response time

• Cycle life

Which battery technology was commercialized in 1991?

• Lithium-Sulfur Battery

• Nickel-Iron Battery

• Lithium-Ion Battery

• Solid-State Battery

Which type of battery has reversible chemical reactions?

• Primary battery

• Secondary battery

• Both primary and secondary

• Neither

What is the role of the electrolyte in a battery?

• Separates the anode and cathode

• Allows ion movement between electrodes

• Prevents short circuits

• Collects current

What type of reaction occurs at the anode?

• Oxidation

• Reduction

• Ion transfer

• Electron transfer

In a lithium-ion battery, the cathode serves as the negative electrode.

• Yes

• No

In a lithium-ion battery, the process of discharging occurs from:

• Cathode to anode

• Anode to cathode
