The exploration and utilization of energy by mankind are carried out incessantly. Although fossil energy such as coal, oil and natural gas are widely used at present, although the reserves are relatively large, it is a non-renewable energy and can also cause the greenhouse effect. Therefore, our exploration of clean energy has never stopped.

　　At present, the clean energy that we can use mainly includes wind energy, solar energy, hydropower, nuclear energy, biological energy, tidal energy, etc.

　　The most direct way to use solar energy is to generate electricity through solar panels. The solar radiation in space is about ten times that of the ground, and it is not affected by weather conditions. It is the theoretically optimal place for solar power generation.

　　In 2008, researchers from the United States and Japan successfully realized the wireless long-distance transmission of microwave-level energy on two islands 90 miles apart. This distance is equivalent to the thickness of the atmosphere that must be penetrated to transmit energy from space orbit to the ground. . This provides technical support for long-distance wireless transmission of energy.

　　The basic idea of a space solar power station is to send a satellite with solar panels to space, and then convert solar energy into electromagnetic waves containing energy. The ideal frequency should be 2.45GH or 5.8GH. Microwaves form an invisible microwave column in the air with a diameter of about one mile. There is an elliptical array antenna called a grid antenna on the ground, which specifically receives microwave energy.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
