Sodium-ion batteries (SIBs) have long been hailed as a cost-effective alternative to lithium-ion batteries, but their performance has been hindered by inefficiencies in the anode material. A new study introduces an innovative approach to improving hard carbon (HC) anodes, which are vital for SIBs. By manipulating the interfacial chemistry of HC through an in situ coupling strategy, researchers have enhanced sodium ion transport and boosted both the storage capacity and rate capability of HC anodes. This breakthrough could be the key to unlocking the full potential of SIBs, making them a viable option for large-scale energy storage and electric vehicles.

In a lush revelation from the forest floor, a new study published in Carbon Research (as an Open Access Rapid Communication) shows that mosses, those quiet, green carpet-weavers beneath our feet—are climate champions in their own right. Led by Dr. Zhe Wang from the China-Croatia “Belt and Road” Joint Laboratory on Biodiversity and Ecosystem Services, CAS Key Laboratory of Mountain Ecological Restoration and Bioresource Utilization, Chengdu Institute of Biology, Chinese Academy of Sciences, and Shanghai Normal University, alongside Dr. Weikai Bao, also of the Chengdu Institute of Biology, this research flips the script on how we view forest carbon storage. Spoiler: mosses matter—big time.
