PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. But large-scale deployment has been a challenge.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. The metal then shrinks again during discharge, as the battery is used.

Thermal Solar Goes Where PVs Can’t

Cars That Think

As electric utilities and policymakers seek solutions for storing and dispatching energy on demand, concentrating solar-thermal power (CSP) is once again gaining traction. Solar-thermal systems use sun-tracking mirrors to reflect sunlight onto a receiver, which contains a high-temperature fluid that stores heat. It's flexible.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

As power grids everywhere increasingly rely on intermittent renewable energy, batteries and other forms of energy storage that can even out the bumps in supply and demand are taking on a crucial role. No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons.
