Modern electronic devices heavily rely on lithium-ion batteries, including smartphones, electric vehicles, and even aircraft.
Even though these batteries are omnipresent in technology, traditional battery designs are reaching their limits in terms of how much energy they can store per unit of battery weight, known as energy density.
Despite efforts to maximize the energy density, we are getting closer to the physical limits of what can be achieved with these traditional lithium-ion batteries.
Now, Amprius Technologies, a battery manufacturing startup has announced their new SiCore™ lithium-ion battery.
Unlike traditional lithium-ion batteries, the SiCore uses a silicon anode instead of a graphite anode, allowing the battery to store 450 watt-hours (energy) per kilogram. This is 80% more than conventional lithium-ion batteries.
According to the company, the significant improvement in energy density makes its application in aviation promising, offering a greater range, improved flight time, and overall performance.
While the battery’s energy density is impressive, the real game-changer is their claim to move the battery to mass production in the near future.
“What makes this SiCore cell different and noteworthy is that it brings that level of extreme performance into a cell chemistry and format that are ready to scale with the existing lithium-ion battery manufacturing processes and equipment in the industry.”
“It’s production-ready, commercially available, and already being qualified by customers today,” said Dr. Kang Sun, CEO of Amprius Technologies in a press release.
