Seattle-based Wibotic says it’s secured $5.7 million in fresh investment to ramp up development of its wireless charging and power optimization systems, five years after being spun out from the University of Washington.

“We’re heading into our toddler phase here,” WiBotic CEO Ben Waters joked during an interview with GeekWire.

Investors in the Series A funding round include Junson Capital, SV Tech Ventures, Rolling Bay Ventures, Aves Capital, The W Fund and WRF. The latest round brings WiBotic’s total investment to nearly $9 million.

Energy venture fund backs a quest for cobalt

KoBold Metals’ quest to find new sources of cobalt, a key ingredient in lithium-ion batteries, has received high-profile backing from Breakthrough Energy Ventures, the $1 billion innovation fund spearheaded by Microsoft co-founder Bill Gates.

Andreessen Horowitz also joined in the Bay Area startup’s funding round, which was disclosed today. The amount of funding, however, went undisclosed.

Breakthrough Energy Ventures was created by Gates and a bevy of other billionaires — including Jeff Bezos, Richard Branson, Michael Bloomberg and Jack Ma — to make long-term investments in cutting-edge energy technologies. KoBold Metals uses artificial intelligence and “machine prospecting” techniques to search for likely locations of cobalt ore.

Boeing’s HorizonX venture investment team says it has led a seed funding round for Cuberg, a California startup focusing on next-generation battery technology for potential aerospace and industrial applications.

Among the most relevant applications would be power storage for electric airplanes and underwater drones — both of which are in Boeing’s wheelhouse.

“Cuberg’s battery technology has some of the highest energy density we’ve seen in the marketplace, and its unique chemistries could prove to be a safe, stable solution for future electric air transportation,” Steve Nordlund, vice president of Boeing HorizonX, said today in a statement.

Australia powers up Tesla’s monster battery

South Australia’s state government turned on the switch for the world’s biggest lithium-ion battery today, marking a signal achievement for rapid deployment of renewable energy resources.

Technically speaking, the 100-megawatt battery bank built by Tesla isn’t the highest-capacity power storage system: Molten-salt batteries, for example, can store more energy for distribution over a longer time. Alphabet’s X team, the “moonshot factory” associated with Google, is currently seeking commercial partners for a megawatt-scale, molten-salt battery project called Malta.

Even in the lithium-ion category, there are bigger power storage systems in the works: A battery bank that’s being built for Southern California Edison can be expanded to store 300 megawatts of power.

But that battery isn’t due for completion until 2021 or so. What’s most notable about the Tesla facility connected to Neoen’s Hornsdale Wind Farm is that it was installed under the terms of a “100 Days or It’s Free” deal with Tesla CEO Elon Musk.

Today’s switching-on ceremony took place just 63 days after the grid-connection agreement was signed in September, although Tesla got a head start on the project before the signing.

Elon Musk hits deadline for big Australian battery

It’s a rare day when Tesla CEO Elon Musk actually finishes a job before the deadline, but that’s what happened with the massive 100-megawatt battery bank that his company built in South Australia.

The world’s largest lithium-ion battery bank has now been fully installed at Neoen’s Hornsdale Wind Farm and is set to be energized for the first time in a matter of days, South Australia’s state government announced today.

In response to a plea from Australian billionaire Mike Cannon-Brookes, Musk promised in July to get the array of Powerpacks installed within 100 days of signing a grid connection agreement, or else the job would be done for free.

Musk had some wiggle room: By the time the agreement was actually signed on Sept. 29, Tesla had already completed half the project. Nevertheless, he was taking a risk on a project that’s thought to cost tens of millions of dollars.

Tonight Musk tweeted his congratulations to the team.

WiBotic unveils wireless charging pad for drones

Seattle-based WiBotic today took the wraps off an integrated wireless charging pad for drones, as well as an onboard charger that weighs just 1.6 ounces.

The two new products are part of the University of Washington spinout’s strategy to provide a system for charging up robotic aerial vehicles as they go about their business, untouched by human hands.

The plug-and-play system is set up to send power wirelessly at short range from the pad’s transmitter to the charger’s receiver. Then the transmission is converted into electricity for a drone’s batteries. It’s an alternative to switching out batteries by hand, or hooking it up to a direct-contact charging system.

Tesla plans to build world’s biggest battery

One hundred megawatts. That’s how much electrical power the world’s biggest lithium-ion battery system will store when Tesla builds it for the state of South Australia.

And it’ll be built in 100 days, or it’s free.

The agreement, announced today in Adelaide, follows through on a pledge that Tesla CEO Elon Musk made during a Twitter exchange with Australian billionaire Mike Cannon-Brookes about South Australia’s power woes back in March.

Spacewalkers finish swapping batteries

Two astronauts made quick work of a battery upgrade today during the International Space Station’s second spacewalk in a week.

NASA’s Shane Kimbrough and French astronaut Thomas Pesquet installed three new adapter plates and hooked up three new lithium-ion batteries during an outing that lasted nearly six hours.

They finished up their primary tasks in less than three hours, leaving plenty of time for “get-ahead” maintenance tasks.

New batteries give a boost to space station

The International Space Station got a power upgrade today when spacewalkers hooked three new lithium-ion batteries into the electrical system.

NASA astronauts Shane Kimbrough and Peggy Whitson spent about six and a half hours outside the orbital outpost to do the installation.

For the past several days, the station’s crew has been using the Dextre robotic arm system to shift old nickel-hydrogen batteries into storage and get the new batteries ready for installation. The lithium-ion battery packs arrived at the station last month aboard a robotic Japanese cargo ship.

Each battery pack is about as big as a coffee table, weighs 400 pounds and is designed to last at least 10 years. They’re made by Aerojet Rocketdyne, and provide 50 percent more energy storage capability than the packs they replace.

Lithium-air battery nirvana comes nearer

A decade from now, we could all be driving low-cost electric cars for hundreds of miles without recharging, thanks to an advance in lithium-air battery technology announced today. Or maybe it’ll be some other lithium-air innovation. Or maybe we’ll see batteries with a different chemistry, such as sodium-air or sodium-lithium.

“The battery of the future is going to encompass a lot of these different technologies,” University of Cambridge chemist Clare Grey told GeekWire.

Grey is the senior author of a study describing a technological twist that promises to remove some of the obstacles that have blocked the path to battery nirvana. The research, featured on the cover of this week’s issue of the journal Science, shows how changing the nanostructure of the electrodes and shifting the chemistry can boost a lithium-oxygen battery’s efficiency and make it more stable.
