Batteries Flashcards
What is the function of a battery in a renewable energy system?
A battery converts chemical energy into electricity and stores it for later use.
What are the four main types of batteries used in renewable energy systems?
Lithium-ion, Lead-acid, Flow batteries, and Sodium-ion batteries.
What are the advantages and disadvantages of lead-acid batteries?
cost-effective but heavier and less durable than lithium-ion batteries.
Why are lithium-ion batteries widely used?
have high energy density, are lightweight, and have a long lifespan.
How do sodium-ion batteries compare to lithium-ion batteries?
function similarly but are more sustainable and cost-effective.
How do batteries support commercial and grid-scale renewable energy?
Utilities use large battery storage systems to integrate renewable energy into the grid.
How do residential systems use batteries?
Homeowners store energy from solar panels for nighttime use or during power outages.
What is the role of batteries in electric vehicles (EVs)?
They power EVs and can also act as mobile energy storage units for homes and grids.
How do batteries benefit off-grid solutions?
They provide power to remote areas, reducing reliance on diesel generators
What are the key challenges in battery technology?
Recycling, cost, safety concerns, material constraints, and lifespan.
Why is battery recycling a challenge?
There is a lack of widespread recycling infrastructure, leading to waste management issues.
Why is the cost of battery technology a concern?
Advanced battery systems require high initial investment.
What safety concerns are associated with batteries?
Some batteries, especially lithium-ion, have risks of overheating and fire.
What are the material limits in battery production?
Mining of lithium, cobalt, and nickel poses environmental and ethical challenges.
How does battery lifespan affect efficiency?
Batteries degrade over time, reducing efficiency and requiring replacements.
What are the advantages of solid-state batteries?
They have higher energy density and faster charging capabilities.
Where are solid-state batteries commonly used?
In electric vehicles, wearables, and portable electronics.
What is the impact of innovative battery technologies?
They accelerate the adoption of renewable energy and create a cleaner future.
