37. The Next Generation of Batteries: Smarter, Safer Power

According to the essay, what is the primary goal of the ongoing work to improve lithium-ion batteries?
1. To make them the only type of battery available.
2. To make them more powerful, safer, and less expensive.
3. To eliminate the need for anodes and cathodes.
4. To ensure they can only be used in electric vehicles.
What is the function of the electrolyte in a battery, as described in the essay?
1. It stores the majority of the battery's energy.
2. It acts as the positive material (cathode).
3. It allows energy to move between the cathode and anode.
4. It is the new solid material that replaces flammable liquid.
The essay states that using silicon in the anode is an improvement because it
1. makes the battery much safer.
2. is cheaper than any other material.
3. allows the battery to store much more energy.
4. eliminates the need for an electrolyte.
What is the main advantage of the dry electrode coating manufacturing process?
1. It creates a solid-state battery design.
2. It uses more effective chemical solvents.
3. It is faster, cheaper, and better for the environment.
4. It allows batteries to be made without a cathode.
The development of solid-state batteries is considered a major future advancement because they
1. use traditional graphite to be more reliable.
2. are the first to use a liquid electrolyte.
3. are safer and can store more power in a smaller space.
4. are manufactured exclusively with the wet coating method.
