Long Battery Life Comes … Finally


One company that wants to repair lithium-ion batteries is 50 percent with Sila Nano, which WIRED was unveiled late last year. Sila Nano technology says it can contain lithium 24 times without inflammation, the company says. And it is currently working with BMW and Daimler on EVs batteries, as well as battery-powered electric batteries.

In September 2021, the maker of the Whoop wristbands was unveiled a new version of its action tracker powered by batteries with Sila Nano technology in them — which is said to be similar to the battery life of a five-day tracker, but with a much smaller battery. The launch of Whoop 4.0 was impressive as it was the first Sila Nano battery to ship with consumer goods. But it was also hampered by a number of customer complaints on Reddit about Hey batteries that can not charge and delay response time from the customer.

Enovix, the company Srinivasan advises, is also working on a silicon solution, but is taking a slightly different approach. It creates what it calls a “3D” design of a silicon battery, which involves inserting electrodes instead of wrapping them inside a battery cell – a process for making a battery that borrows from. making chip method, which the company claims to make better use of space within batteries.

Enovix co-founder and CEO Harrold Rust points out four common problems with the spread of silicon-anode batteries. One is inflammation caused by silicon; another, its production. (Gene Berdichevsky, founder of Sila Nano, too said WIRED that the production of silicon nanoparticles is difficult to grow.) Another problem is electrical power, which range from material to material of lithium-ion batteries. And, says Rust, “silicon anode alone has a relatively short life span, which means that by the end of the century, perhaps, your battery has lost 20 percent of its capacity.”

However, Rust is a potential addition of silicon anode. “We are confident that what we say our battery can do, will do, based on the experiments we have done,” he says. “And we look forward to being in the spotlight this year.”

WIRED asked HyperX, the maker of 300-hour headphones, if the company is using silicon-anode technology in the upcoming sales. A spokesman for the company, Gurpreet Bhoot, said, “We can’t know much about the device,” and reiterated that the new headphones will be the first game head on the market that offers 300 hours of battery life on the phone. one price. Later, after further inquiries, the spokesman said the HyperX design is his. In the meantime, HyperX may be squeezing out extra battery life as old-fashioned: by making larger batteries, building with less efficient processors, or using other methods to reduce power consumption when headphones are not used.

Which is not a bad a way to change battery life. Srinivasan points out that there are “similarities” that are taking place with the technological advancement of battery, which means that the technology is going well because marketers want to push battery life to a higher level.

“I’m thinking about Apple’s M1 device, which is obviously Apple’s, but the idea is that technicians are reducing the amount of batteries,” says Srinivasan, “when there is a single capacity added to batteries. Perhaps the most important thing we see here is the connection. both. ”
