Hybrid Solid-liquid Cathode to Boost Lithium Primary Battery Energy

Despite increasing energy demand, there have been few fundamental innovations in cell chemistries in the past 40 years.

Primary (non-rechargeable) batteries have energy density three times higher than Li-ion, and are critical in applications where recharging is impractical, such as medical implants, IoT sensors, and defense. Despite increasing energy demand, there have been few fundamental innovations in cell chemistries in the past 40 years. During their PhD, Gao developed a primary battery chemistry that can boost the energy density of the state-of-the-art by 50%, while also improving safety, with little to no increase in cost. The high energy density enables better patient life quality, versatile device design, and 30% reduction in total end-of-life waste generation for primary batteries and/or associated devices.
