Our new paper from @yicuistanford lab on calendar aging of Lithium metal is out @NatureEnergyJnl! We study Li metal batteries when they're not in-use (for ex: cell-phone turned off) and give some insight into the chemical stability of unique electrolytes

A 23-year-old Santa Cruz local caught a towering wave near Half Moon Bay that was recently estimated to be 108 feet tall, which would make it easily the world’s largest wave ever surfed.
The current world record is 86 feet.

How do some advanced F-based electrolytes plate uniform Li anodes, while standard electrolytes give "dendritic" anodes?
For my entire PhD, I thought Li plating kinetics were behind this...but thermodynamics turns out to still be king.
Last paper!

@KangXu_Echem Yes, that’s a very nice paper. Was happy to see it. The results are similar and complementary.
They highlight how potential impacts electrolyte reduction, our work points out how it can affect Li morphology
tldr: fast charge transfer correlates with weak solvation (F-based elytes) and uniform plating, but this contrasts with kinetics-based predictions
Instead, more positive Li/Li+ potentials in weakly solvating high CE elytes increases surface energy and favors uniform plating

This work was really a crazy 2 yr+ journey that involved the pandemic, many terrific collaborators and mentors @YuzhangLi@yicuistanford, and several surprises and pivots.
Congrats to the team and thanks for such great work.
Fast charging is tough for Li metal batteries ("dendrites"), so we asked how does the Li plating mechanism change with slow and fast charging?
In @NanoLetters today, we mapped out Li plating mechanisms to help with future design of fast charge solutions.

Some nice insight here on how intermolecular interactions can tune reactions on surfaces. Implications for catalysis and electrochemistry.
Nice work, congratulations everyone and @JMUChemistry!
