‘Nanochains’ could increase battery capacity, cut charging time

20.09.2019 | Purdue University | www.purdue.edu

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery’s negative electrode material. If the battery runs out of these ions, it can’t generate an electrical current to run a device and ultimately fails.

Materials with a higher lithium ion storage capacity are either too heavy or the wrong shape to replace graphite, the electrode material currently used in today’s batteries.

Nanochains

Purdue University scientists and engineers have introduced a potential way that these materials could be restructured into a new electrode design that would allow them to increase a battery’s lifespan, make it more stable and shorten its charging time. The study, appearing as the cover of the September issue of Applied Nano Materials, created a net-like structure, called a “nanochain,” of antimony, a metalloid known to enhance lithium ion charge capacity in batteries.
