I have learned that lithium batteries have huge environmental challenges. Better recycling methods and research into other minerals offers choices for the future.
Short answers
You have tested your design solutions by collecting and analyzing data from them. Now it is time to compare the two design solutions. You will identify the best characteristics of each of your design solutions. If possible, you will combine the best characteristics of each design to come up with an optimal method for monitoring and minimizing a human impact on the environment.
The most important question you need to ask yourself about your design methods is this: Does each design method provide all the information I need? Most engineers will agree that most design methods do not provide all the information that is needed for an investigation. Engineers usually use the best features of several different design methods and come up with a method they can use that will give them the best information.
Let’s look at an example. Suppose someone asked you to research whether apples or oranges were the most popular fruit. For your first method, you might interview 10 people to ask them if they buy more apples or more oranges. For your second method, you might go to your local grocery store and ask the manager to give you sales data for apples and oranges.
Chances are, you will find that there are aspects of each design method that are useful and aspects of each design method that are not useful. To create an ideal design method, you would choose the best features of both methods and combine them both into an optimal design.
Use the activities to write your reflections on the design methods you created.
Compare your designs. Use your comparisons to develop and present a new and even
better design.

### Reflections on the Design Methods for Lithium Batteries
**Comparison of Design Solutions**
1. **Recycling Improvements**:
- **Pros**:
- Leverages existing infrastructure, potentially reducing costs and implementation time.
- Could significantly lessen the environmental impact by decreasing the demand for newly mined materials.
- Supports a circular economy approach by keeping lithium in circulation.
- **Cons**:
- Requires significant investment in R&D to innovate on recycling technologies.
- Current recycling methods may still be inefficient and not able to recover all valuable materials.
2. **Alternative Materials**:
- **Pros**:
- Addresses the root problem of lithium extraction by seeking materials that are more abundant and less damaging to the environment.
- Potentially paves the way for sustainable battery technology by using renewable resources.
- **Cons**:
- Uncertainty regarding the performance and longevity of alternative materials compared to lithium.
