Nickel-based battery chemistry meant to compete with LFP battery cells on longevity while retaining the properties that people like in nickel-based batteries, like higher energy density, which enables longer range with fewer batteries for electric vehicles.
This is quite exciting, even if only proof of concept. Nickle based battery could last 100 years while still favorably comparing to LFP cells on charging and energy density. One of the keys appears to be using an electrolyte with LiFSI lithium salts
"Ultra-high precision coulometry and electrochemical impedance spectroscopy are used to complement cycling results and investigate the reasons for the improved performance of the NMC cells. NMC cells, particularly those balanced and charged to 3.8 V, show better coulombic efficiency, less capacity fade and higher energy density compared to LFP cells and are projected to yield lifetimes approaching a century at 25C."
Wow! Can you believe it?
