What kind of Na-ion Batteries ?

Rechargeable batteries that use sodium instead of lithium

Why we use sodium (abundance )

Sodium is more common and cheaper then lithium

Why we should use na-ion batteries then li-ion batteries

- It operates at lower voltage

- Na-ion has high performance then li-ion

- Easy compatibility

- Cheaper

What is graphene batteries ?

Rechargeable batteries that use graphene , a special kind of carbon

Does graphene good at conductivity ?

Yeah , graphene is really good at flowing of electricity

Why are the advantage of graphine ?

- Large surface area ( Lot of space on its surface → More energy store

- Mechanixal strength ( graphine are so strong )

- Chemical stability ( graphone doesn’t easily get damaged by chemicals or charging

- Eco friendly ( Because its been made by carbon then its eco-friendly )

Disposal of batteries ?

• Safe handling

• Proper Disposal

• Separation by chemistry

• Recycling

• Hazards od Improper Disposal

Safe Handling ::

Careful of used batteries to avoid damage

Proper Disposal ::

Take batteries to special place for recycling

Separation by chemistry ::

Recycling ::

Take batteries to recycling centers

Hazards of improper disposal

Batteries contain harmful chemicals that can harm the enviroment

Second Use of batteries ?

• Reuse (some batteries can be used again in different things before recycling )

• Remanufacturing ( Batteies or part can be fixed up to make them work )

• Energy storage system ( used batteries can be used to store energy for later )

• Research and development ( Scientists are studying new ways to use old batteries )

• Circular Economy ( A way of thinking where things are reused and recycled )
