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...

Batteries are everywhere. They power our phones, laptops, and even cars. But have you ever wondered what makes a battery tick? Well, it's all about the chemistry inside. Scientists have been working hard to make batteries better, especially for electric vehicles. They've been focusing on something called the cathode-electrolyte interphase, or CEI for short. This is w...
