Of this global capacity, China''s operational energy storage project capacity totaled 32.7GW, a growth of 4.1% compared

Development history. The development of energy storage in China has gone through four periods. The large-scale development of energy storage began around 2000. From 2000 to 2010, energy storage technology was developed in the laboratory. Electrochemical energy storage is the focus of research in this period.

Fig. 1 (a) depicts the XRD pattern of BNSBFT x (x = 0.2, 0.25, 0.33, 0.5, 0.75) ceramics in the 2θ range 20 − 70 . It can be found that all phases are the perovskite structure with no impurity, indicating that Nd 2 O 3, Sm 2 O 3, and nano-BaTiO 3 have been completely incorporated into the BNSBFT x ceramics. ceramics.
