University of Houston: Engineer Exposes Structural Weakness Driving Lithium-ion Battery Failure
A University of Houston engineer has found that lithium dendrites—hazardous growths inside lithium-ion batteries that power everything from smartphones to electric vehicles—are unexpectedly strong and brittle, signaling a need to rethink future battery design.
The growth and penetration of lithium dendrites through electrolytes and separators remain key challenges to realizing high–energy density lithium-metal batteries.
The dendrites are tiny crystal ‘needles’ that form inside the batteries for a variety of reasons, from fast charging to low temperatures. Though minute, measuring just hundreds of nanometers (more than 100-times smaller than a strand of human hair), lithium dendrites can cause catastrophic damage and safety hazards including short circuits and fires.
“For decades, the scientific community assumed that solid-state electrolytes could easily block dendrites because lithium was thought to be a soft, ductile metal. We have proven they are actually brittle and snap like glass,” said Yan Yao, Hugh Roy and Lillie Cranz Cullen Distinguished Professor of electrical and computer engineering. Yao’s work is published in Science, in an article co-authored by his colleagues from Rice University, Georgia Institute of Technology and…

March 4, 2026 — Texas state tax revenue from oil and natural gas was down considerably during February 2026 when compared with a year ago, while the state’s overall sales tax income was up nearly 4-percent.
