Materials with a higher lithium-ion storage capacity are either too heavy or the wrong shape to replace the graphite electrode material currently used in today’s batteries. Purdue University scientists and engineers have introduced a potential way that the battery 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 created a net-like structure, called a “nanochain,” of antimony, a metalloid known to enhance lithium-ion charge capacity in batteries.
The researchers compared the nanochain electrodes to graphite electrodes, finding that when coin cell batteries with the nanochain electrode were only charged for 30 minutes, they achieved double the lithium-ion capacity for 100 charge-discharge cycles.
