Ultra-long battery life is coming…finally


Sila Nano is a company dedicated to improving lithium-ion batteries by up to 50%. Wired was introduced late last yearSila Nano’s technology can reportedly hold about 24 times as much lithium without swelling, the company said. It is currently working with BMW and Daimler on electric vehicle batteries as well as consumer electronics batteries.

In September 2021, hilarious wristband maker Whoop revealed a A new version of its activity tracker It’s powered by a battery with Sila Nano technology – which is said to match the 5-day battery life of previous trackers, but with a much smaller unit. The release of Whoop 4.0 is notable because it includes the first Sila Nano battery for a consumer product.But it was also marred by a series of customer complaints on Reddit battery that won’t charge and delayed response time from customer service.

Enovix, the company Srinivasan suggested, is also working on silicon-based solutions, but it takes a slightly different approach.It’s making so-called “3D” silicon cell architectures that include stacking electrodes rather than coiling them inside cells — a battery design approach borrowed from chip manufacturing The company says this approach allows for more efficient use of space within the battery.

Harrold Rust, co-founder and CEO of Enovix, identified at least four challenges inherent in silicon anode batteries for widespread adoption. One is the expansion that occurs with the silicon; the other, its manufacture. (Gene Berdichevsky, founder of Sila Nano, also Tell “Wired” The fabrication of silicon nanoparticles is difficult to scale. ) another problem is energy efficiency, which varies by material in Li-ion batteries. And, Rust says, “Silicon anodes tend to have poor cycle life on their own, which means that after a hundred cycles, your battery can lose 20 percent of its capacity.”

Still, Rust is bullish on the potential of silicon anodes. “Based on the tests we’ve done, we’re pretty confident that what we’re saying the battery can do, it will,” he said. “We expect this year’s product to demonstrate that.”

WIRED asked 300-hour headphone maker HyperX if the company uses silicon anode technology in its upcoming products. “We couldn’t get that level of design detail,” said Gurpreet Bhoot, a spokesman for the company, reiterating that the new headset would be the first gaming headset on the market to offer 300 hours of battery life. Single charge. Later, after more inquiries, the spokesperson said that HyperX’s design is proprietary. Right now, HyperX may be extending battery life the old-fashioned way: by designing a bigger battery, building with a super-efficient processor, or using some method to reduce power consumption when the headset isn’t in use.

which is not bad Ways to improve battery life. Srinivasan noted that all of these advancements in battery technology are happening “in parallel,” that is, electronics becoming more efficient as entrepreneurs work to maximize battery life.

“I’m thinking about Apple’s M1 chip, which is obviously unique to Apple, but the idea is that the techs are minimizing the load on the battery,” Srinivasan said, “while also adding that strength to the battery. Maybe we’re here The important thing to see is a fusion of those two things.”
