“We were looking for the easiest, cheapest, and fastest way to improve lithium metal cycling life,” said study co-lead author Wenbo Zhang, a Stanford PhD student in materials science and engineering. “We discovered that by resting the battery in the discharged state, lost capacity can be recovered and cycle life increased.
Lithium-ion batteries keep getting better and cheaper, but researchers are tweaking the technology further to eke out greater performance and lower costs. Some of the motivation comes from the price volatility of battery materials, which could drive companies to change chemistries. “It’s a cost game,” Sekine says.
Though battery research tends to focus on cathode chemistries, anodes are also in line to get a makeover. Most anodes in lithium-ion batteries today, whatever their cathode makeup, use graphite to hold the lithium ions. But alternatives like silicon could help increase energy density and speed up charging.
Furthermore, the team introduced polyethylene glycol to regulate the physical properties and facilitate Li-ion diffusion, resulting in the thick high-capacity electrode and maximum energy density found in Li-ion batteries.
Addionics, an Israeli company, has found that tweaking the geometry of these sheets can boost the batteries’ performance. Unlike the smooth sheets used in today’s batteries, Addionics’s offering has hills and valleys; like a “tiny egg carton”, says Moshiel Biton, the company’s founder.
