With the continuous advancement of science and technology, the quality of human life has also been improved. There is heating in winter and air conditioning in summer, but behind these enjoyments, the demand for energy is also increasing. Traditional fossil energy will pollute the environment, while environmentally friendly new energy sources such as solar energy and wind power generation have to “watch the sky”. On January 8, 2021, the whole of Europe almost fell into a blackout due to a sudden drop in the frequency of the power grid. Some experts worry that if the use of solar and wind energy with fluctuating supply increases, the blackout crisis will recur.

 

How to convert environmentally friendly

but unstable energy sources into sustainable and storable energy to meet the rising demand Portugal Phone Number has always been an area of ​​research in the scientific community. Under the Paris Climate Agreement, Europe must reduce carbon dioxide emissions by 80% within 30 years. Achieving this goal will require large-scale reforms, including reducing the use of gasoline and switching power plants from coal, natural gas and oil to renewable energy sources; these changes will require a combination of large-scale energy storage, a key tool is the battery. 1 Some companies are studying the use of giant battery packs to store electricity generated by solar and wind farms to maintain a stable power grid. The production of batteries requires a lot of energy. Taking electric vehicle battery packs as an example, each battery pack produces 3.5 to 4 tons of carbon dioxide.

Some battery manufacturers are building,

recycling systems, hoping that by 2030, at least half of the raw materials will come from recycled batteries, with the goal of producing the most environmentally friendly batteries in the world. Under the general trend of environmental protection, in recent
