What is the main advantage of using lithium iron phosphate (LiFePO4) batteries?

• High energy density, long cycle life, and improved safety.

• Medium energy density, medium cycle life, and unchanged safety.

• No energy density, no cycle life, and no safety.

• Low energy density, short cycle life, and decreased safety.

What is the main difference between a primary battery and a secondary battery?

• Primary batteries are more expensive than secondary batteries.

• Primary batteries have a higher energy density than secondary batteries.

• Primary batteries are non-rechargeable while secondary batteries are rechargeable.

• Primary batteries have a longer lifespan than secondary batteries.
