According to researchers including Vilas Pol and V Ramachandran of Purdue University in the US, materials with high lithium-ion storage capacity are either too heavy or mis-sized to replace graphite – as materials commonly used in batteries Is electrode.

Researchers found that when coin cell batteries with nanocane electrodes were charged for 30 minutes, they achieved twice the lithium-ion capacity for 100 charge-discharge cycles compared to commonly used graphite electrodes.

While some batteries already use similar electrodes, the material making them diffuses up to three times the lithium ions, which over time becomes a safety hazard.

“You want to adjust that type of expansion in your smartphone’s battery. That way you’re not carrying something unsafe,” Poole said.

According to the researchers, the nanocane holds the lithium ion potential constant for at least 100 charge-discharging cycles.

Pol said, “There is essentially no change from Cycle 1 to Cycle 100, so we have no reason to think that Cycle 102 will not be the same.”
