The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable . It employs ions as . The battery uses vanadium's ability to exist in a solution in four different to make a battery with a single electroactive element instead of two. For several reasons. The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids. [pdf]

The Qixi Festival is celebrated to commemorate the tale of love between a cowherd, Niulang, and a weaver girl, Zhinü. Legend has it that in a celestial realm, Niulang and Zhinü, who were a god and a goddess, fell deeply in love. However, the laws of heaven forbade their union.Zhinü, the granddaughter of the Queen. .

Ice storage air conditioning is the process of using ice for . The process can reduce energy used for cooling during times of . Alternative power sources such as solar can also use the technology to store energy for later use. This is practical because of water's large : one of water (one cubic metre) can store 334 (MJ. Cold energy storage is an effective way to relieve the gap between energy supply and demand. It can be seen that air conditioner cold storage technology is a critical technique to realize the utilization of new energy sources and energy savings. Generally, liquid–solid phase change material (PCM) is the main type of energy storage material. [pdf]
