- Enevate Founder and Chief Technology Officer shares new silicon-dominant Li-ion battery innovations
“It’s exciting to see what started off as an anode technology mainly targeting high energy density show additional benefits such as ultrafast charging. The unique properties of our developed silicon-dominant conductive active material film has led to additional benefits for mobile users,” said Dr. Park. “For example, we have demonstrated ultrafast charging with 90 percent cell charge in 15 minutes and 50 percent in as little as 5 minutes, and benchmarks are showing between 35 percent to 50 percent longer smartphone runtime.”
Enevate’s innovations, supported by 25 issued and pending patents, allow for a silicon composite anode with a gravimetric energy density of about 2800 mAh/g and very high initial Coulombic efficiencies of 93 percent for the anode and 90 percent for full cells, while controlling the well-known issues associated with volumetric expansion and contraction. The composite is comprised of carbon as a conductive matrix, silicon as the main active material, and silicon-carbide as a nanometer-scale layer protecting the silicon surface. In addition, Enevate technology is compatible with current high-volume manufacturing processes, leading to lower costs and providing the ability for use in existing form-factors.
Dr. John Goodenough, a key inventor of the modern Li-ion battery, said, “Enevate is using a different technical approach for silicon anodes that is truly unique and innovative to deliver both ultrafast charging and high energy density. I‘m impressed that their technology and process is practical, highly manufacturable, and has the potential to be sufficiently inexpensive for high-volume mobile devices.”
