What are the technology improvements of the 4th generation of LFP batteries, and what do they mean for BESS applications?

Australian developer Edify Energy has reached financial close on the Ganymirra and Majors Creek solar-plus-storage projects near Townsville in North Queensland, featuring 360MWp of solar generation and 300MW/1,200MWh of battery storage.

The largest grid-scale battery energy storage system (BESS) project in the Czech Republic has gone online, supplied by a company invested in by lithium-ion OEM CATL. 

In this deep-dive, we go through and analyse all of the technical features and claims of CATL’s new sodium-ion grid-scale BESS product, including its ‘millisecond-level self-healing’.

CATL’s energy storage division represented 19.23% of the Chinese battery manufacturer’s total revenue in the first half of 2026.

ESS Tech Inc is deploying sodium-ion BESS in the US with Juniper Energy, while CATL deploys its sodium-ion technology in Eastern Europe with Solarpro.

UAE state-owned IPP Masdar has reached financial close on what it has claimed is the world’s “first gigascale 24/7 renewable energy project”.

System integrator Alfen and battery company CATL have struck a 5GWh partnership for sodium-ion BESS deployments in Europe.

We analyse recent details that have emerged on battery OEM CATL’s zero-degradation BESS technology, which was first announced two years ago.

System integrator HyperStrong will deploy sodium-ion BESS first in its home market of China, before bringing a product to the international markets, its president of technology said.
