An electrochemical cell consists of electrodes and electrolytes. An electrode is a which is immersed in an electrolyte. But an electrolyte is a substance that conducts electric currents.

Electrochemical cells have both chemical and electrical cells.

What is an electrochemical cell?

03

An electrochemical cell is a kind of device that transforms chemical energy into electrical energy.

It is the only type of cell in a battery and it help transfer electrical energy into chemical energy.

How do batteries work

04

Batteries work by taking chemical energy and making it into electrical energy

They work because there are negative electric charges in them.

Why are batteries rechargeable?

05

They have a speacial chemicals to allow them to recharge

They have cells that allow them to recharge.

What is the difference between a wet and dry cell?

06

The difference between a wet and dry cell is that a wet cell use liquid electrolytes while dry cells use a paste.

the difference between them is that wet cells use paste and dry cells use liquid electrolytes.

Why are chemical reactions important in electrochemical cells?

07

Chemical reactions are important in electrochemical cells because they make one electrode negatively charged while the other electrode is positively charged.

Chemical reactions are important in electrochemical cells because they make all the electrodes negitiely charged

What are batteries?

08

Batteries are devices that changes electric enegy into mechincal enegy so they can help power up things.

A battery is a device that converts chemical energy into electric energy so that it can power other devices and things.

What is the difference between different types of batteries (lithium, Alkaline, AAA, C, D, 9v)?

09

The difference between the types of batteries is the size. The bigger the size the more energy it can store.

The difference between the types of batteries is that there are two, one battery is both postive and the other is both negitive
