Cheap Battery Made from Abundant Materials

The three primary constituents of the battery are aluminum (left), sulfur (center), and rock salt crystals (right). All are domestically available Earth-abundant materials not requiring a global supply chain.

  Lithium is expensive, hard to extract in the quantities that will be required to meet demand for EV batteries and renewable energy storage, and often dangerous. Formulating a battery that doesn’t need lithium, even for some applications, would help ensure the lithium supply we have now lasts longer

Brushing Thin Films onto Electrodes Preserves Batteries

Brushing metal powders into the surface of lithium anodes shows promise to curtail the threat of dendrites that damage recyclable batteries, according to scientists at Rice University.

­A bit of brushing may be the secret to making better rechargeable lithium batteries.  The Rice University lab of chemist James Tour introduced a technique to tune the surface of anodes for batteries by simply brushing powders into them. The powder adheres to the anode and becomes a thin, l

 ACE Batteries Drive LFP Technology Closer to Li-ion for EVs

How the prismatic cells fit directly into the battery pack

When modern EVs were introduced, the main reason for their initial slow sales was the range. However, battery technology has progressed and now some of the latest vehicles can get almost 600 miles on a full charge. As always in engineering, when one problem is solved another crops up, or in the case of electric veh
