Battery manufacturing quality in the automotive industry is becoming increasingly important with the growing popularity of electric and hybrid-electric vehicles.
This article describes a novel micro-compression instrument and technique for determining the hardness of individual particles using controlled uniaxial compression. Brief examples of the technique used to characterize and compare the hardness of battery anode materials are provided.
Rapid growth in electric vehicle sales along with an increasing interest in fuel-cell-electric powertrain systems presents the auto industry with serious and largely unanticipated quality-control issues.
EV battery cells, battery packs, electric motors and other systems modified for EV applications all require leak testing to assure both quality and safety.
The rapid and unexpected growth in the production of alternative drive systems is presenting automakers and their suppliers with a host of leak-detection challenges to ensure vehicle safety and quality.
Automakers in Europe, the Asia-Pacific region and the United States are struggling with performance and safety issues associated with electric and hybrid-electric cars.
Since the early 1990s Lithium ion batteries have entered industrial markets as energy storage technology for mobile consumer electronics and battery-operated tools.
