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.

Scientists create setup to measure wave-induced power losses in floating PV Researchers have measured the power loss of a 50 W panel stationed in a 30-meter wave tank. Based on ten different scenarios, they were able to draw an empirical equation for the prediction of power loss, with the highest loss being measured at 12.7%.

Using surplus PV power for seasonal underground thermal storage Scientists have proposed a new system that uses surplus PV energy in the spring and the autumn to charge up underground thermal energy storage for later use in the summer and winter. They have simulated it on a school facility in Seoul, with a few optional configurations for thermal storage. Power savings were up to 39%.

Optimizing bifacial solar panels for floating PV applications in tropical freshwater New research from India shows how bifacial solar modules should be deployed to achieve strong performance in floating PV projects planned on tropical freshwater. Their experimental setup demonstrated that higher efficiency gains are achievable by gauging panel height, water depth, and tilt angle.
