Sakati's Solid State Battery Technology

The best indicator that something is on track is when more investment follows. This battery technology could double the range of electric vehicles and run time of battery powered devices and home appliances.


battery iconDyson, the British vacuum firm, has invested $15 million.The company has made its first ever external investment, in Sakti3 which formed at the University of Michigan. The company says that its solid-state battery technology is a huge improvement on existing lithium-ion batteries, storing about twice as much power.Dyson is likely to use the batteries in its cordless vacuum cleaners, which are at the moment powered by the old technology.

A spinoff from the University of Michigan, Sakti3 has now garnered $50 million in funding to date, having taken on a little over $11 million over two rounds back in 2010, in addition to a $2 million Series A in 2009, a previously unannounced $14 million Series B-1 in 2012, and a $3 million grant.

For Dyson, this deal represents one of the first investments to emerge from the $2.3 billion fund it set aside last year to plow into so-called “future technologies,” as it looks to bring 100 machines in four new portfolios to market in the next four years.

The Technology

Sakti’s vacuum deposition technology was invented using advanced numerical models, coupled with real laboratory data on materials. The team began its work on computers. they methodically modeled the most promising, low cost materials, and developed battery compositions and configurations that offered great cell performance. The team also modeled the scale up of battery production, right from the start. They  developed plant models that enabled them to create the right processes on the right tools. The aim was to create the most scalable, flexible and profitable methods possible.

Early prototypes were made on simple equipment – thee challenge to produce great battery cells on equipment that was not overly specialized.

Sakti3’s solid state battery use solid electrodes, rather than liquid chemicals. As well as being much safer than the existing technologies, it also avoids many of the problems that plague the new batteries made by its competition, such as those that are based on sulphur which can leak and cause danger.

Battery Investment.

Leading the pack would have to be Tesla’s 5 billion dollar investment into a battery manufacturing facility.  A few months back, Samsung led a $17 million investment round into Seeo to help build better batteries for electric cars, and shortly after acquired the battery business from Canadian company Magna International. Elsewhere, Microsoft cofounder Bill Gates has invested in at least three energy storage companies, while Warren Buffett acquired Duracell in a $4.7 billion deal back in November.

New hydrogen production breakthrough

Hundreds of companies over the years have claimed a breakthrough in hydrogen production. This is the latest from JOI Scientific from Florida.


Hydrogen is the most abundant fuel on the planet. The trouble is it is normally bonded or locked to other elements. To break the bonds requires more energy that can be recovered (Electrolysis) or a consumable to chemically unlock the bond. As we saw with Solar trends earlier this year, many claims of low energy inputs fail to reveal the chemical reactions involved. The holy grail is to unlock the hydrogen with minimal energy and or consumables. To date this has not been achieved.

The second problem is storage. The molecules are so small it leaks through anything being compaounded by  hydrogen is highly flammable. Not ideal for distribution. This problem is overcome with making hydrogen on demand.

JOI Scientific claims to be able to produce hydrogen on the spot with very little energy input.The energy is only used at the start and enough hydrogen is produced to sustain the reaction and produce surplus hydrogen. The big question is they claim the small electrical input triggers a chemical reaction. What consumable is used in the chemical reaction?

They are not revealing much information about the process and are busy doing another funding round.

One reason I published this story is the excellent video explaining the hydrogen.

Other Media

The following is a small excerpt from a story by Paul Brinkmann that  appeared in the Orlando Sentinel

Stealth company claims hydrogen fuel breakthrough at Space Center

Called Joi Scientific, the company claims to have found a revolutionary process to create hydrogen fuel from water – a new green source of energy.

The company co-founder, veteran technologist Traver Kennedy, says he has landed a significant investment in the company’s Series A round, which is the first institutional investment in venture capital terms.

Kennedy believes Joi’s technology can change the course of history by providing a relatively inexpensive and efficient source of hydrogen fuel.

Among scientists and environmentalists, finding a safe and efficient way to produce hydrogen fuel is considered a “holy grail” to replace fossil fuels. Hydrogen burns cleanly and at high temperatures, without giving off any greenhouse gases.

But hydrogen is also highly explosive and dangerous – the world abandoned all hope of using hydrogen in airships, for example, after the horrific Hindenburg explosion in 1937.  But hydrogen fuel has been used widely in the space program at Kennedy, cooled to extremely low temperatures to make it liquid.

There’s a lot that Kennedy is not saying about the company yet, in preparation for a wider reveal early in 2016.

In an interview, he said the tagline for the company, soon to be viewed on its website will be, “Formed by social entrepreneurs and technology leaders, funded by the money that started Silicon Valley.” But he declined to elaborate on the meaning of the term.


There is very little information here, we have to wait and see. I rank this as a chance as they have serious investors and a real scientific and engineering research team. They also raised money from companies that do due diligence. This is the complete opposite of the circus act that was called Solar Hydrogen trends that turned out to be a elementary  school science project.

The key is the consumable that is used in the chemical reaction, the cost and how easy it is to reverse.
