Recently, the "Shandong High-speed Weihai 200MW/400MWh Shared ESS Power Station Project", invested and constructed by the Energy Investment Group, was successfully energized at one go, marking the official grid connection operation of the power station. The project has a total investment of approximately 400 million yuan, covers an area of about 50 mu, and has a total installed capacity of 200MW/400MWh. It adopts a hybrid ESS technology of "LFP battery + sodium-ion battery", consisting of 39 sets of 5MW/10MWh LFP batteries and 2 sets of 2.6MW/5.2MWh sodium-ion batteries. Connected to the Shandong power grid at a voltage level of 220kV, it fully leverages the advantages of both technologies, effectively enhancing the power grid's peak shaving and valley filling capabilities as well as the comprehensive utilization rate of new energy.

The South Korean government will invest a total of KRW 235.1 billion across 27 projects this year to develop core and foundational technologies in the semiconductor, display, and secondary battery sectors. On January 14, the Ministry of Science and ICT finalized the 2026 Implementation Plan for the Core and Foundational Technology Development Program, which covers the semiconductor, display, and secondary battery industries. Of the 27 projects, six new initiatives will be launched this year with combined funding of KRW 24 billion. In the secondary battery sector, the government will continue to support the development of core technologies for next-generation batteries, including aqueous zinc batteries, sodium-ion batteries, and lithium-metal batteries, as well as programs for master’s and doctoral-level talent development and international cooperation.

Li-ION BATTERY China 2025 Officially Announced and Scheduled

[SMM Analysis: The Uncommon Yet Not Ordinary Prussian White: How Can Low-Cost Materials Sustain Competitiveness?] SMM News on June 18: Driven by the goal of carbon neutrality, sodium-ion batteries have emerged in the fields of energy storage systems (ESS) and start-stop applications due to their advantages of abundant resources and low cost. The Prussian route, as one of the three major cathode routes for sodium-ion batteries, is gradually gaining attention. Prussian materials are currently divided into two types: Prussian blue and Prussian white. The main reason for the color difference between the two cathodes lies in crystalline water. Prussian white requires further dehydration based on Prussian blue, so precise control of crystalline water is necessary for Prussian white...

CATL's First Batch of Sodium-ion Automotive Power Batteries Exported: On June 3, Ningde Customs issued a certificate for the use of dangerous goods packaging for a batch of sodium-ion automotive power battery packs produced by CATL, marking the official export of the country's first batch of sodium-ion automotive power batteries and opening up a new dual-track path for China's new energy industry to "go global" with high-end lithium batteries and popularized sodium-ion batteries.

[SMM Analysis] This article introduces knowledge related to energy storage in a straightforward manner by addressing three questions: What is energy storage? Why do we need energy storage? How is energy storage implemented? At its core, energy storage is a technological system designed to address the temporal and spatial mismatches in electricity supply and demand, enabling the transfer of energy across time through forms such as chemical energy (e.g., batteries) and potential energy (e.g., pumped hydro storage). Its core architecture comprises four major modules: energy storage battery cells serve as the energy carriers, with the LFP route dominating the market; PCS converters facilitate AC-DC conversion; the BMS system monitors the safety of tens of thousands of battery cells in real time; and the EMS system optimizes charging and discharging strategies based on electricity price signals. The primary demand for energy storage covers the power generation and grid side, as well as the demand side. Current technological iterations focus on large-capacity battery cells, such as the 587Ah cell from CATL and the 684Ah cell used in combination by Sungrow.
