Zinc-ion batteries are gaining traction for their safety, affordability, and eco-friendliness. Yet, they face some tough challenges, like dendrite growth and hydrogen gas formation, which can cause problems. To tackle these issues, scientists have been using highly concentrated electrolytes. While this method works, it also makes the electrolyte thicker, slows down i...
Sodium-ion batteries (SIBs) are stepping up as strong contenders in the world of energy storage. They are seen as a promising alternative to lithium-ion batteries, especially for large-scale applications. However, making SIBs that can handle different temperatures, deliver high performance, and last a long time is still a big challenge. Scientists have recently deve...
Aqueous sodium-ion batteries are gaining traction for their safety and affordability. However, they have a few drawbacks. The main issue is their limited electrochemical stability window and their tendency to freeze in cold temperatures. This can hinder their use in real-world situations. Researchers have found a way to tackle these problems. They added a substa...
A new material has been created that could change the game in energy storage and water splitting. This material is a mix of NbPO5 and CoFe2O4, carefully put together in a two-step process. The first step involves a hydrothermal growth method. The second step is electrodeposition. This combination gives the material a 3D structure. This structure is great for conducti...
The quest to improve energy storage and conversion has led to some clever tricks with carbon materials. One standout method involves using a special salt to create carbon nanosheets with plenty of defects and pores. These aren't flaws, but features that make the carbon better at storing energy and catalyzing reactions. The process starts with a mix of leafy zeolitic ...
Batteries are everywhere, from phones to electric cars. Sodium-ion batteries (SIBs) are a type of battery that has been getting a lot of attention lately. The problem is, most batteries struggle in extreme temperatures. They either freeze up in the cold or overheat in the heat. This is a big issue for places with harsh winters or scorching summers. A new type of ele...
In the world of renewable energy, solar power is a big deal. It is a way to harness the sun's energy and use it to heat things up. One interesting way to do this is by using something called phase change energy storage. This is a fancy way of saying that energy from the sun is stored as heat during the day and then released at night. It is like having a solar-powered...
Renewable energy sources like wind and solar are crucial for reducing carbon emissions. However, their unpredictable nature makes it tough to keep the power grid stable. This is where advanced energy storage systems come in. Among these, gravity energy storage systems (GESS) stand out. They are scalable, cost-effective, and eco-friendly. A recent study introduced a ...
Zinc-based batteries are gaining attention as a safe and reliable way to store energy. These batteries, known as zinc aqueous batteries (ZABs), have a lot of potential, but they have some big problems. Specifically, they struggle with side reactions and dendrite growth, which make it hard to use them on a large scale. To tackle these issues, researchers have come up...
The world is hungry for energy, and finding ways to store it sustainably is a big deal. Biomass-derived carbon dots, or B-Cdots, are stepping up to the plate. These tiny powerhouses are made from natural materials, making them eco-friendly and budget-friendly. Plus, they can be produced on a large scale without harming the environment. This is a win-win for both sust...
