Extreme fast charging of commercial Li-ion batteries via combined thermal switching and self-heating approaches

Nature Communications, 2023
The mass adoption of electric vehicles is hindered by the inadequate extreme fast charging (XFC) performance (i.e., less than 15 min charging time to reach 80% state of charge) of commercial high-specific-energy (i.e., >200 Wh/kg) lithium-ion batteries ...

Multilinear Algebra for Distributed Storage [PDF]

SIAM Journal on Applied Algebra and Geometry, 2021
An $(n, k, d, α, β, M)$-ERRC (exact-repair regenerating code) is a collection of $n$ nodes used to store a file. For a file of total size $M$, each node stores $α$ symbols, any $k$ nodes recover the file, and any $d$ nodes repair any other node via sending out $β$ symbols.

A Micelle Electrolyte Enabled by Fluorinated Ether Additives for Polysulfide Suppression and Li Metal Stabilization in Li-S Battery

Frontiers in Chemistry, 2020
The Li-S battery is a promising next-generation technology due to its high theoretical energy density (2600 Wh kg−1) and low active material cost. However, poor cycling stability and coulombic efficiency caused by polysulfide dissolution have proven to ...
