Scientists develop sodium battery as alternative to lithium-ion

Scientists are exploring sodium for its potential in cost-effective power facilities. However, sodium's reactivity with water and its tendency to form a solid electrolyte interface in batteries pose challenges. Purdue University researchers have developed a method using ultrasonic dispersion to stabilize sodium, enhancing battery performance and capacity.

What is one of the main advantages of using sodium in power facilities?

• It is more stable than other elements.

• It is lighter than lithium.

• It is abundant and cost-effective.

• It does not react with water.

What is a significant issue with sodium ions in batteries?

• They dissolve in the electrolyte.

• They explode when exposed to air.

• They stick to the anode, forming a solid interface.

• They cause the battery to overheat.

How do sodium ions affect the charging ability of a battery?

• They increase the battery's lifespan.

• They create a solid interface that can grow too large.

• They reduce the battery's capacity.

• They enhance the charging speed.

What technique did Purdue University scientists use to stabilize sodium?

• Magnetic levitation

• Thermal evaporation

• Ultrasonic dispersion

• Electrochemical deposition

What is the purpose of suspending sodium in hexane?

• To increase its melting point

• To make it more conductive

• To prevent it from reacting with air

• To ensure even particle distribution
