Fluorine-based electrolyte can improve capacity and stability of rechargeable batteries
Rechargeable batteries are pivotal to the success of many disruptive technologies, particularly for electric vehicles and energy storage system. However, capacity, stability and range anxiety remained some critical issues. In rechargeable batteries, materials like lithium-ion anode, nickel and high voltage cathode materials can cause instability.
A group of researchers at the University of Maryland (UMD), the US Army Research Laboratory (ARL), and Argonne National Laboratory (ANL) has recently achieved some success in increasing capacity of the rechargeable battery through using lithium-metal anode (aggressive electrodes) as well as stabilising electrode materials with a fluorine-based electrolyte.
The new battery can provide reliable and high-quality power even in the several charging and discharging situations. The fluorinated electrolyte can ensure around 93% of battery capacity even after the thousand charge cycles which are significantly higher than the current lithium-ion batteries. It implies that a vehicle can run the same number of miles for years without capacity deterioration. Moreover, an extra portion of fluorine can make ignitable electrolytes completely fire resistant.
Commodity Inside expects that this new development in lithium-ion batteries can help the automotive and renewable energy market.
