Answers to Student Questions
Advantages of the electric car are:
City driving is the main use for which electric cars are designed. This includes commuting, running local errands and trips around town.
Onboard computers in electric cars indicate level of charge and remaining range of travel, making it less likely that you will allow the battery to run down, minimizing “range anxiety”.
This statement is false. Electric cars were built as early as 1828, and had become prevalent in the 1900s, until improvements in the gasoline-powered car gave it dominance.
Oxidation occurs at the lead plate in the lead-acid battery. This process involves the loss of electrons from the lead plate as it reacts to form lead(II) sulfate.
Recharging a lead-acid battery involves pumping electrons into the battery from an outside source. This causes the oxidation of lead(II) to lead(IV), releasing two electrons in the process.
Today’s electric cars (unlike those of the 1900s, which used lead-acid batteries) use lithium-ion batteries.
The cathode (the positive terminal) is made of “a type of layered lithium oxide, such as lithium cobalt oxide (LiCoO2)”, while the “negative electrode, or anode, is made of graphite—a form of pure carbon.
Four advantages of lithium-ion batteries over lead-acid batteries:
Three disadvantages of electric cars:
