Aug 18, 2025 · This article compares sodium sulfur batteries vs lithium-ion batteries, focusing on their principles, performance, pros and cons, and applications to help users make informed
Jun 1, 2025 · Solid-state batteries stand at the forefront of energy storage, promising heightened safety, increased energy density, and extended longevity compared to conventional lithium-ion
Apr 2, 2025 · The project combines 40MWh of sodium-ion batteries with the remainder lithium-ion and is the largest of its kind in China, the firm said, and therefore almost certainly the world.
Aug 12, 2025 · Sodium batteries offer cost, safety eco benefits over lithium but have lower energy density. Ideal for grid storage low-speed EVs. They complement lithium, not replace it.
Baochi Energy Storage Station, China's first large-scale lithium-sodium hybrid energy storage station, starts operations in Southwest China's Yunnan Province on May 25, 2025.

Sodium batteries have struggled to reach even half the storage capacity of the best lithium batteries, which hold more than 300 watt-hours of energy per kilogram (Wh/kg). But Gui-Liang Xu, a battery chemist at Argonne National Laboratory, says, “There are multiple avenues to go down” to address the challenge.
LIBs, in particular, have become the frontrunners in energy storage due to their high-energy density, low self-discharge rates, long cycle life, and absence of memory effects. [1, 2] However, their large-scale application is limited by the high cost of lithium, its uneven geographic distribution, and finite reserves.
The station marks a technical breakthrough by integrating lithium-ion and sodium-ion batteries within the same site. Lithium batteries, known for their maturity and fast response, handle high-frequency grid regulations.
CSG estimates that the hybrid lithium-sodium model reduces system costs by around 30% compared with sodium-only storage, offering a more balanced trade-off between efficiency and economics.
Lithium batteries, known for their maturity and fast response, handle high-frequency grid regulations. Sodium-ion batteries, developed with China’s proprietary technology, offer higher thermal adaptability and greater raw material security.
