Sodium-ion batteries still have a number of weaknesses that could be remedied by optimising the battery materials. One possibility is to dope the cathode material with foreign elements. A team fro .
Qingdao University researchers have synthesized high-performance titanium dioxide-based anode materials with excellent cycling stability, while German scientists have used operando techniques to observe how solvated sodium ions embed themselves in electrodes.
The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. A joint research group from HZ .
