Researchers develop lithium-sulfur battery that can be cut, folded
By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.

Most home battery storage systems meet warranty claims, new research finds
It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of usable capacity per year on average, meaning good news for the industry as most warranties in the market can be met with the implementation of capacity reserves.
Banking on batteries in Chile
The Chilean solar market is booming but as curtailment grows, a hybrid approach to generation is gaining ground. Storage project announcements are coming thick and fast as co-location with wind turbines offers cost efficiency and a smoother generation profile. Meanwhile, new capacity mechanism rules could take Chile one step closer to runaway battery growth.
