Current Collector

An MIT battery material could offer a more sustainable way to power electric cars. The lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel.

The future of wearable technology may have just taken a significant leap forward with the introduction of stretchable fabric-based lithium-ion batteries.

Single crystal Li[Ni 0.5 Mn 0.3 Co 0.2 ]O 2 //graphite (NMC532) pouch cells with only sufficient graphite for operation to 3.80 V (rather than ≥4.2 V) were cycled with charging to either 3.65 V or 3.80 V to facilitate comparison with LiFePO 4 //graphite (LFP) pouch cells on the grounds of similar maximum charging potential and similar negative electrode utilization. The NMC532 cells, when constructed with only…

One of the challenges of realizing smart dust concepts, as well as nano- and microrobotics in general, is a lack of equally small on-chip power sources for ubiquitous anytime anywhere operation. Now, researchers have created an on-chip micro-Swiss-roll battery by using a self-assembly process known as micro-origami. The batteries are 3 mm in length and about 178 micros in diameter and the self-assembly mechanism…

Carbon nanotubes have shown promise for everything from microelectronics to aviation to energy storage. Researchers think this material might one day fulfill the science fiction dream of creating an elevator to space.

Researchers recovered lithium from batteries on a small scale by using mechanical force

Six individual sneakers worn by Michael Jordan during the Bulls' championship-clinching games will be put on auction Thursday. They're estimated to sell for up to $10 million.

Lawrence Livermore National Laboratory (LLNL) scientists have created vertically aligned single-walled carbon nanotubes on metal foils that could be a boon for energy storage and the electronics industry.

QuantumScape has announced impressive performance figures for what may be the first commercially viable lithium metal solid state battery.

Formally referred to as a Safety Reinforced Layer (SRL), the composite material measures just one micrometer thick – or about 1/100th the thickness of a human hair....

London-based Addionics has raised $39mn in funding as it eyes commercialisation of its 3D 'current collectors' that can boost the performance of any battery, regardless of its chemistry. The ...

Several companies aim to lower the cost of the high-capacity anode material in an effort to dethrone graphite

Many electric vehicles are powered by batteries that contain cobalt—a metal that carries high financial, environmental, and social costs.

The 3D-printed batteries will use local resources found on the Moon and Mars.
