1

Create the battery components dictionary

Create a dictionary called components with these exact entries: 'Anode': 'Lithium metal', 'Cathode': 'Sulfur', 'Electrolyte': 'Organic liquid'

EV Technology

# Create the components dictionary with specified keys and values
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys and values.

2

Add the advantages list

Create a list called advantages containing these exact strings: 'High energy density', 'Lightweight', 'Low cost'

EV Technology

components = {
    'Anode': 'Lithium metal',
    'Cathode': 'Sulfur',
    'Electrolyte': 'Organic liquid'
}
# Create the advantages list with specified items
# Your code here

Need a hint?

Use square brackets [] to create a list with the given strings.

3

Add the challenges list

Create a list called challenges containing these exact strings: 'Short cycle life', 'Poor conductivity', 'Volume expansion'

EV Technology

components = {
    'Anode': 'Lithium metal',
    'Cathode': 'Sulfur',
    'Electrolyte': 'Organic liquid'
}
advantages = ['High energy density', 'Lightweight', 'Low cost']
# Create the challenges list with specified items
# Your code here

Need a hint?

Use square brackets [] to create a list with the given strings.

4

Combine all information into a summary dictionary

Create a dictionary called summary with keys 'Components', 'Advantages', and 'Challenges'. Assign the variables components, advantages, and challenges as their respective values.

EV Technology

components = {
    'Anode': 'Lithium metal',
    'Cathode': 'Sulfur',
    'Electrolyte': 'Organic liquid'
}
advantages = ['High energy density', 'Lightweight', 'Low cost']
challenges = ['Short cycle life', 'Poor conductivity', 'Volume expansion']
# Create the summary dictionary combining all previous data
# Your code here
