Compared to the prosperity of power battery energy storage and grid connected energy storage, household energy storage in China seems a bit inconspicuous. The characteristics of household energy storage are small individual scale, scattered layout, and the equipment manufacturers and investors are mainly of small and medium-sized private enterprises. At the same time, there are…
Household battery energy storage + refrigerator may be applied in the same way as air conditioner + photovoltaic, but it will not become a product that most people can use. Batteries + refrigerator Recently, the solution of household energy storage + refrigerator has become a new topic, Some home appliance manufacturers have begun to…
As of now, global leading battery companies plan to produce more than 3.5TWh of lithium batteries by 2025. Under the tide of large-scale expansion of lithium battery production, as an important part of lithium batteries, the demand for electrolyte has increased significantly, and the price has also risen. Outlook to 2025 The agency predicts…
