Practice - 5 Tasks

1fill in blank

easy

Complete the sentence to describe the main difference of solid-state batteries.

EV Technology

Solid-state batteries use a [1] instead of a liquid electrolyte.

Drag options to blanks, or click blank then click option'

Aliquid electrolyte

Bplasma electrolyte

Cgas electrolyte

Dsolid electrolyte

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing solid electrolyte with liquid electrolyte.

Thinking the electrolyte is a gas.

Solid-state batteries use a solid electrolyte, which replaces the liquid electrolyte found in traditional batteries. This improves safety and energy density.

2fill in blank

medium

Complete the sentence to explain a key advantage of solid-state batteries.

EV Technology

Solid-state batteries typically offer [1] energy density compared to traditional lithium-ion batteries.

Drag options to blanks, or click blank then click option'

Alower

💡 Hint

Common Mistakes

Assuming solid-state batteries have lower energy density.

Confusing energy density with battery size.

Solid-state batteries have higher energy density, meaning they can store more energy in the same space compared to traditional lithium-ion batteries.

3fill in blank

hard

Fix the error in the statement about safety of solid-state batteries.

EV Technology

Solid-state batteries are [1] likely to catch fire than liquid electrolyte batteries.

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing 'more' instead of 'less' for fire risk.

Assuming safety is the same as traditional batteries.

Solid-state batteries are less likely to catch fire because their solid electrolyte is more stable and less flammable than liquid electrolytes.

4fill in blank

hard

Fill both blanks to complete the sentence about challenges in solid-state battery development.

EV Technology

One major challenge is [1] the solid electrolyte with electrodes and [2] manufacturing costs.

Drag options to blanks, or click blank then click option'

Aconnecting

Breducing

Cincreasing

Disolating

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'isolating' instead of 'connecting'.

Choosing 'increasing' instead of 'reducing' for costs.

Connecting the solid electrolyte with electrodes is difficult due to material interfaces, and reducing manufacturing costs is a challenge for mass production.

5fill in blank

hard

Fill all three blanks to complete the dictionary describing solid-state battery features.

EV Technology

features = {{'{'}}'energy_density': [1], 'safety': [2], 'cost': [3] {{'}'}}

Drag options to blanks, or click blank then click option'

A'high'

B'improved'

C'expensive'

D'low'

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up 'low' and 'high' for energy density.

Choosing 'low' for cost instead of 'expensive'.

The features of solid-state batteries include high energy density, improved safety, and expensive cost compared to traditional batteries.
