Answer :
Final answer:
The internal grids of automotive batteries are primarily made of lead and are often enhanced with other elements for increased durability. Both characteristics are essential for the optimal performance of lead-acid batteries. Thus, the correct answer is that both statements are true.
Explanation:
Understanding the Internal Grids in Automotive Batteries
The internal grids in automotive batteries, specifically lead-acid batteries, primarily serve as the electrodes that participate in the chemical reactions during battery discharge and charging.
- The grid is made mainly of lead: The anodes in each cell are made of plates or grids of lead, providing a large surface area for the necessary chemical reactions.
- The lead used to make the grid is enhanced with other elements for durability: To improve the performance and longevity of these batteries, the lead grids are often alloyed with other materials, like antimony or calcium, which enhance their resistance to corrosion and improve their overall structural integrity.
In summary, both statements are accurate: the grid is made mainly of lead, and the lead is enhanced with additional elements to increase durability.
