Lithium batteries and hydrogen fuel cells which is the mainstream of the future electric car?

Source: 2020 - 03 - 29 but as hits: lithium-ion batteries and hydrogen fuel cells, which is the mainstream of the future electric car? The future energy system is supplied by batteries or fuel cells? Now we live in a surrounding this question a great struggle of the age. The Mercedes - Mercedes Benz ( 梅塞德斯- benz) GLC - for it Suv is equipped with a fuel cell system in the past few years, China has witnessed the rise of lithium battery, we have become a global leader in lithium battery production and consumption. Look at elon musk: hydrogen fuel cells' stupid ' 'hydrogen is a stupid choice' youtube video capture as early as 2015, iron man said: 'if you want to choose an energy storage mechanism, you should choose to methane and propane, because they are easier to manufacture. 'I just think, Hydrogen fuel cell) Stupid manufacturing, storage and use of hydrogen in the car is very difficult. '' if you take a piece of solar panels to batteries directly, compare it to the electrolytic, with hydrogen, oxygen separation, squeeze the hydrogen that is roughly half of the energy. 'of the future market is fuel cells' over the years, Toyota has been betting on the hydrogen fuel cell battery driven vehicles, in order to achieve the strategy of zero emission cars. Hydrogen fuel cell is the Toyota Toyota use of advanced technology in different mirai to the car. Toyota's hydrogen fuel battery as a power station. It through the chemical reaction of oxygen and hydrogen to generate electricity. Compared with lithium batteries, hydrogen fuel cell has obvious advantages of battery life. The same range of 500 kilometers, lithium battery charge usually need a long time, super-fast charging will take an hour and a half, while hydrogen dye cells only need 3 minutes can be filled with hydrogen. In addition, the hydrogen energy density than lithium ion, and the energy density of the two order of magnitude is not the same. Hydrogen fuel cell vehicles but also has the following advantages: hydrogenated oil, and generally only need three to five minutes. For electric vehicle charging is a slow process. Even tesla launched a super charging station, usually also need more than an hour. The main components of the hydrogen fuel cell is hydrogen, we know that water is the chemical formula of h 2 o, hydrogen fuel cells in service life, won't cause pollution to the environment. Lithium ion battery, on the other hand, contains a lot of heavy metals, if not recycled correctly, will cause more pollution to the environment. Hydrogen fuel cell energy storage density high, and light weight, a longer range generally. Generally more than 500 kilometers, and pure electric vehicles is according to the size of the battery capacity, now most of the range of pure electric vehicles in 300 kilometers, a few models can reach 400 to 500 kilometers. On the other hand, Europe is another base of hydrogen fuel cell research. With the deepening of the German electricity transformation, a large number of new energy into the grid. European Julich research center is one of the largest electric power research institute, advocate the new power generation ( Wind power) Into hydrogen, to power grid volatility and the consumption of renewable energy power generation problem. Professor, director of the institute Detlef Stolten said: 'in the wind, with the help of the existing power rating of the wind turbine will produce so much, in 2050, it will replace the German households now require heating with natural gas. 'in addition, in power market adjusted, peak hours will reduce 90 TWH per year. We can use 70% of the actual power to electrolysis of water, hydrogen fuel can be driven 16 million fuel cell car. 'the fuel battery can provide power supply. Family, even is depend on the small family of gas network can be used at the same time the fuel cell. When we talk about mobility, we don't forget to fuel cell compensation function in the whole power system. ”
