Cornell University engineers have created a new lithium battery that can charge in under five minutes -- faster than any such battery on the market -- while maintaining stable performance over extended cycles of charging and discharging.
The breakthrough could alleviate "range anxiety" among drivers who worry electric vehicles cannot travel long distances without a time-consuming recharge.
Many electric vehicles are powered by batteries that contain cobalt — a metal that carries high financial, environmental, and social costs.
MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries).
Have you been in a situation in which what you think you know is strongly challenged?
A few weeks ago, I was showcasing NI’s battery validation lab solutions to a diverse group of people and one of the best questions I got was spot on. Where is the novelty?
Northvolt’s mission is simple: make the world’s greenest battery. One of the most important aspects of their operation is considering the battery production as a circular process, like a loop. This “loop” goes from sourcing raw materials, through battery production, and to recycling so the active material can be reused to make new batteries (Figure 01). As an example, Northvolt aims at making 95 percent of cell material reusable after end-of-life, thus closing the loop and restarting the process.
Batteries are expensive, scary things. If we're not worried about them catching fire, we're worried about them losing sufficient capacity and range to render our electric vehicle both unusable and unsalable. A good battery management system (BMS) is a great defender against either disaster, and Texas Instruments has just introduced new cell and pack monitors that up the standard of BMS accuracy and precision enough to potentially boost an EV's real-time remaining range figures—even when the battery is new.
The electric car market is booming, so it is important to learn more about how the ‘heart’ of an electric car, the lithium-ion battery pack, works.
The battery pack is an intelligent device that stores and delivers energy via its modules equipped with lithium-ion cells. The battery production process is crucial to ensure optimal safety and performance, and being the most delicate component of new ‘zero-emission’ engines, it requires numerous precautions during production.
In this article we will investigate: how are batteries for electric cars produced?
Britishvolt has secured five weeks of funding from Glencore and the battery company’s 300 staff have agreed to take a steep pay cut, as the UK government-backed battery startup races to find a buyer or new longer-term investor to avoid collapse.
Energy storage via rechargeable battery technology powers our digital lifestyles and supports renewable energy integration into the power grid. However, battery function under cold conditions remains a challenge, motivating research on improving the low-temperature performance of batteries. Aqueous batteries (in a liquid solution) do better than non-aqueous batteries in terms of rate capability (a measure of energy discharged per unit of time) at low temperatures.
A new type of battery made from electrically conductive polymers—basically plastic—could help make energy storage on the grid cheaper and more durable, enabling a greater use of renewable power.
The batteries, made by Boston-based startup PolyJoule, could offer a less expensive and longer-lasting alternative to lithium-ion batteries for storing electricity from intermittent sources like wind and solar.
