Science: Enabling Technologies Flashcards
What is an anode?
A positively charged electrode
What is a cathode?
A negatively charged electrode
What is an electrolyte?
A liquid or gel which contains ions and can be decomposed by electrolysis.
How does wireless charging work?
It works by transferring energy from the charger to a receiver in the back of the phone via electromagnetic induction.

Yes. A recent study suggested that having strong wireless chargers in your household could potentially affect your health.
Which ion is considered to be lightest and most efficient battery solution?
Lithium ions.
What are anodes typically made out of in a lithium-ion battery?
Graphite
How do bacteria-based batteries work?
The batteries use respiration to convert biochemical energy into biological energy.
Capacity
Capacity is how much space there is available to hold something or the amount that something can produce.
