In this lesson students will explore the chemical reaction that occurs within a lead-acid car battery and the role of the battery within a car prior to creating their own batteries.
Be sure to label the experiment items, such as the galvanized nails as having zinc in them. It may be helpful to guide the students back to the idea of the lead-acid battery and to remind them of what types of materials are the best conductors of electricity. A brief tutorial on how to use a multimeter may be necessary.
Have the students brainstorm where those materials might be found on earth. Explain that the students will be working in groups to learn more about the raw materials that make up different types of batteries: lead-acid, alkaline, nickel-cadmium, zinc-carbon, lithium-ion. Place the students into groups of three or four students.
Hyperphysics website containing diagrams of the chemical reactions occurring in a lead acid battery. Kinds of Energy website provides an atomic diagram of the movement of electrons. Lead Acid Battery website provides an inside view of a lead acid battery.
It is also important for students to understand that a battery consists of a cathode, an anode, and an electrolyte. Elaborate: Now that the students understand that a chemical reaction takes place in a battery, which enables electrons to move and cause an electric current, it is time for them to experiment.
The Anatomy of a Battery webpage can be used to help students understand the primary parts of a battery. Ask the students to share their ideas about the materials that might be used to make batteries, both the inside and outside of the battery.
The reaction that takes place between the acid and the metal should also be emphasized and can be explained using information from the Acids and Metals website. Similarly, the Aus-e-tute website provides detailed information about the chemical equations involved in the production of electricity from a lead-acid battery.
This updated SRM presents a clarified mission and vision, a strategic approach, and a path forward to achieving specific objectives that empower a self-sustaining energy storage ecosystem that develops, delivers, and deploys breakthrough solutions to meet a range of real-world applications, across multiple time horizons.
First established in 2020 and founded on EPRI's mission of advancing safe, reliable, affordable, and clean energy for society, the Energy Storage Roadmap envisioned a desired future for energy storage applications and industry practices in 2025 and identified the challenges in realizing that vision.
Target future states collaboratively developed as visions for the beneficial use of energy storage. Click on an individual state to explore identified gaps to achievement. Energy storage is essential to a clean and modern electricity grid and is positioned to enable the ambitious goals for renewable energy and power system resilience.
This Energy Storage SRM responds to the Energy Storage Strategic Plan periodic update requirement of the Better Energy Storage Technology (BEST) section of the Energy Policy Act of 2020 (42 U.S.C. § 17232 (b) (5)). The SRM is being posted in draft form for public comment to inform the final version of the SRM.
The Energy Storage Roadmap was reviewed and updated in 2022 to refine the envisioned future states and provide more comprehensive assessments and descriptions of the progress needed (i.e., gaps) to achieve the desired 2025 vision.
In January 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan Period, emphasizing the fundamental role of new energy storage technologies in a new power system.
When it comes to energy storage, there are specific application scenarios for generators, grids and consumers. Generators can use it to match production with consumption to ease pressure on grids.
