Overview：Lithium batteries are not energy in the strict sense, because lithium batteries are not like chemical batteries. The chemical battery itself is the energy source, by the chemical reaction in the battery to generate current, the reaction is over, the battery life is over. Lithium batteries do not generate energy in themselves, they only store energy. When used, discharge can be recharged when the electricity is used up. So electricity itself depends on external power supply.

At present, one of the most typical misconceptions is to treat the lithium battery electric vehicle as a new energy vehicle. This is unreasonable because lithium battery cars are still driven by charging lithium iron phosphate car battery. The real electric vehicle is a future vehicle powered by fuel cells which is far from practical application.

Some people have discussed whether lithium batteries can replace oil, which is a false proposition in itself. As a vehicle power, lithium batteries are of course possible to replace gasoline, but where does the lithium battery come from? At present, the proportion of solar and wind energy is very small, and nuclear energy is not much, mainly relying on fossil fuels such as coal, gas and oil. In fact, it is not difficult to burn oil, it is easier than burning coal, and crude oil can be directly used to burn electricity, without refining. If oil prices drop to a certain level, coal-fired power plants can easily be converted to fuel oil plants. That is to say, although the main users of oil are automobiles, the main problem is the price. If the car doesn't use it, it can find new uses in the power plant unless other cheaper and cleaner sources of energy are added. Therefore, electric vehicles may change the use of oil, the amount of change can also be, but not completely replace.
Lithium batteries are not energy sources, but they can make new energy possible. Solar energy, for example, can be stored in lithium ion batteries for electric cars and used at night. Because of the uncertain wind volume, the wind load also fluctuate. When the wind is strong, more electricity is generated, but not necessarily used up, it can be stored and used when the wind is small.
Lithium batteries are not useless for driving cars. The advantage of lithium-ion electric car batteries is that by changing the way energy is used, the quality of electricity is improved and the possibility of reducing emissions is provided. There are two main types of vehicle emissions, one is particulate pollutants, PM2.5 responsible for fog and haze, the other is carbon dioxide, nitric oxide and sulfur dioxide, carbon dioxide is a greenhouse gas, the latter two are caused by acid fog and acid rain.

Today's fuel vehicles, one car a diesel engine, the use of oil efficiency is not high, and the combustion of particles produced by pollution can not be collected, directly discharged into the atmosphere. If lithium batteries are used only for electricity, the task of generating electricity will be given to the power plant. Now the power plant is more efficient, that is, less energy is used to generate electricity, the production of carbon dioxide is relatively small. And carbon dioxide capture and collection is relatively easy. And power generation can be replaced not only by fossil fuels, but also by water, solar, wind, tidal, geothermal, and even nuclear energy, which emit very little, providing the possibility for real emission reductions.
