New 'bumpy' battery works at cold temperatures

Chinese chemical experts have tested lithium ion batteries to -35 degrees Celsius.

Positive side of two electrically charged plates within battery loses ions, which flow via electrolyte to negative plate.

In frigid temperatures, ions have trouble leaving the electrolyte and reaching the negative plate.

New study published in ACS Central Science recommends replacing graphite with a colbalt molecule.

By heating the composite to high temperatures, scientists pushed the atoms into a flat plate that is nonetheless bumpier than graphite.

With additional bumps, lithium ions can better attach and function. Adjusting the carbon anode's surface electron configurations
