Energy storage constructions have been motivated by the popularity of renewable energy, especially solar. This has led to the creation of lithium-ion batteries to ensure energy can be stored and used. Because of the integration of storage and photovoltaic, the fluctuation and intermittency of photovoltaic power generation are easy to overcome. This can also smoothen the photovoltaic output of power plans. https://www.lithiumbatterychina.com/blog/2022/09/13/top-10-lithium-solar-energy-storage-battery-manufacturers-in-china/
