Scientists in Germany have analyzed the thermal runaway behavior of sodium-ion batteries and lithium-ion batteries inside a 10-L reaction vessel. They have thermally abused 30 samples, each under a different state of charge level, and have found that both types suffered from runaway when the charge is at least 50%.

Scientists in Spain have simulated a system that uses both power-to-heat-to-power thermal batteries and lithium-ion batteries for energy storage. The hybrid system reportedly achieved a 7% lower LCOE compared to a PV system relying solely on lithium batteries, while simultaneously increasing PV self-consumption by up to 20%.

Scientists in Spain have simulated the combination of power-to-heat-to-power storage systems with lithium-ion batteries to supply energy needs and heat pump production of an electrified dwelling. PV self-consumption was found to increase by up to 20% and levelized cost of energy decrease by 7%.

US scientists have developed a lithium-ion battery for electric vehicles that enables high range and fast charging in cold weather. The battery uses a single-ion conducting glassy solid electrolyte coating and does not require changes to chemistries or production processes.

While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand.

Energy storage is the new solar for an increasing number of Chinese PV manufacturers. However, China still requires enabling policies for storage to provide the end-market volumes needed to bolster the fortunes of manufacturers old and new.

Taking a rigorous approach to inspection is crucial across the energy storage supply chain. Chi Zhang and George Touloupas, of Clean Energy Associates (CEA), explore common manufacturing defects in battery energy storage systems (BESS’) and how quality-assurance regimes can detect them.

It is extremely unlikely that a battery storage system will smoke, burn, or explode, despite a spate of recent reports. But what happens if something does go wrong? Do insurance companies pay out? Do premiums go up? How do insurers assess the issue?

Having discussed battery chemistry in a previous article, Volytica diagnostics here examines the causes of battery degradation and how to extend device lifetimes, ahead of a pv magazine webinar tomorrow.

The Brazilian town of Vale do Jequitinhonha (MG), which stands out worldwide in mineral production, is the stage of a multisectoral program for the use of Brazilian lithium. The government is now exploring the opportunities of the area in the energy transition.
