Monash University researchers' new lithium-sulfur battery tech delivers roughly twice the energy density of lithium-ion batteries, as well as speedy charging and discharging – enabling the sort of power delivery that's critical for eVTOL flight.

Battery tech firm ProLogium has taken the wraps off its 100% silicon composite anode battery. The Taiwanese company claimed a major leap in energy density and charging efficiency, promising 186 miles of range from a five-minute charge.

Panasonic has announced it's ready to begin mass production on its long-awaited 4680 lithium-ion battery cells, specifically designed to boost range, power, charging and efficiency in electric vehicles, while also reducing cost.

When you picture a sci-fi energy source, glowing green crystals are right up there. Scientists in China have now demonstrated just that, in the form of a “micronuclear battery” that can provide continuous low levels of power for decades.

China leads the world in solar power. And not just by a small margin either. It has over twice as much solar power as the next highest country, the USA. Where do you store any excess solar energy? Answer: in ridiculously big batteries.

Researchers say they've built and tested a 'structural battery' that packs a device or EV's chassis with energy, saving a ton of weight. It could unlock smartphones as thin as credit cards, laptops at half the weight and a 70% boost to EV range.

Lithium is a finite resource, and the more we lock inside rechargeable batteries, the less we have to use. A new speedy method to free the element from such sources could be a game changer in terms of the material's availability.

Deep-tech startup Sinonus is working to commercialize a groundbreaking new breed of multifunctional carbon fiber. In its vision, the wonder-composite will serve as a structural battery for everything from electric aircraft to windmills.

A new heat-to-energy converter has reached a record efficiency of 44% – the average steam turbine manages about 35%, for comparison. This thermophotovoltaic cell is a major step on the way to sustainable, grid-scale renewable energy storage.

Amprius began shipping its remarkable silicone-anode batteries in 2022, laying claim to the world's highest-density battery cells along the way. It's now focusing attention on a unique use case: a military-spec wearable battery for warfighters.

Last August, CATL presented the Shenxing battery, an LFP pack capable of adding 400 km of range in 10 minutes. This year, the company has rolled the tech into the Shenxing Plus, which combines four-figure range and even faster charging rates.

Rad Power Bikes already ensures that all of its models meet UL safety standards, but has now gone further with the introduction of the Safe Shield Battery, which incorporates technology designed to protect against overheating.
