Lithium's Narrow Paths Limit Batteries

If you could shrink enough for a fantastic voyage across a lithium battery electrode, you'd see the level of charge at every scale is highly uneven. This is not good for the battery's health. Researchers who recognize the problem worked to view in great detail how the various particles in an electrode interact with lithium during use.

Molten-Salt Battery: Towards Seasonal Storage of Grid-Scale Energy

Scientists have created a battery designed for the electric grid that locks in energy for months without losing much storage capacity. The development of the "freeze-thaw battery," which freezes its energy for use later, is a step toward batteries that can be used for seasonal storage: saving energy in one season, such as the spring, and spending it in another, like autumn.

Rethinking Wave Energy Converters Using Variable-Geometry

A major challenge currently facing wave energy technology is the achievement of cost competitiveness. Because they must be designed to be robust enough to withstand large wave loads and unforgiving sea states, about 35%-50% of wave energy converter costs can be attributed to device structural costs alone. Reducing the structural cost and increasing energy capture are two paths toward reducing wave energy's levelized cost of energy, thereby increasing its attractiveness as a major renewable energy source.

Rivian: Electric Passenger Trucks

Rivian, the US electric passenger truck startup, has had a rollercoaster ride over the past several months, including a wild IPO that briefly saw Rivian become the fourth most valuable automaker in the world. Yet, the share price soon fell as Rivian missed delivery targets (delivering just 920 vehicles in 2021); investor Amazon turned to Stellantis. IDTechEx explores the company's strengths, weaknesses and future.

Device Wraps Around Hot Surfaces, Turns Wasted Heat to Electricity

The energy systems that power our lives also produce wasted heat — like heat that radiates off hot water pipes in buildings and exhaust pipes on vehicles. A new flexible thermoelectric generator can wrap around pipes and other hot surfaces and convert wasted heat into electricity more efficiently than previously possible.
