Y Combinator-backed Holy Grail is using machine learning to build better batteries – gpgmail


For a long, long time, renewable energy proponents have considered advancements in battery technology to be the holy grail of the industry.

Advancements in energy storage has been among the hardest to achieve economically thanks to the incredibly tricky chemistry that’s involved in storing power.

Now, one company that’s launching from Y Combinator believes it has found the key to making batteries better. The company is called Holy Grail and it’s launching in the accelerator’s latest cohort.

With an executive team that initially included Nuno Pereira, David Pervan, and Martin Hansen, Holy Grail is trying to bring the techniques of the fabless semiconductor industry to the world of batteries.

The company’s founders believe that the only way to improve battery functionality is to take a systems approach to understanding how different anodes and cathodes will work together. It sounds simple, but Pereira says that the computational power hadn’t existed to take into account all of the variables that go along with introducing a new chemical to the battery mix.

“You can’t fix a battery with just a component,” Pereira says. “All of the batteries that were created and failed in the past. They create an anode, but they don’t have a chemical that works with the cathode or the electrolyte.”

For Pereira, the creation of Holy Grail is the latest step on a long road of experimentation with mechanical and chemical engineering. “As a kid I was more interested in mechanical engineering and building stuff,” he says. But as he began tinkering with cars and became fascinated with mobility, he realized that batteries were the innovation that gave the world its charge.

In 2017 Pereira founded a company called 10Xbattery, which was making high-density lithium batteries. That company, launching with what Pereira saw as a better chemistry, encapsulated the industry’s problem at large — the lack

So, with the help of a now-departed co-founder, Pereira founded Holy Grail. “He essentially told me, ‘Do you want to take a step back and see if there’s a better way to do this?’” said Pereira.

The company pitches itself as science fiction coming from the future, but it relies on a combination of what are now fairly standard (at least in the research community) tools. Holy Grail’s pitch is that it can automate much of the research and development process to create new batteries that are optimized to the specifications of end customers.

“It’s hard for a human to do the experiments that you need and to analyze multidimensional data,” says Pereira. “There are some companies that only do the machine-learning part and the computational science part and sell the results to companies. The problem is that there’s a disconnection between experimental reality and the simulations.”

Using computer modeling, chemical engineering and automated manufacturing, Holy Grail pitches a system that can get real test batteries into the hands of end customers in the mobility, electronics, and utility industries orders of magnitude more quickly than traditional research and development shops.

Currently the system that Holy Grail has built out can make 700 batteries per day. The company intends to  build a pilot plant that will make batteries for electronics and drones. For automotive and energy companies, Holy Grail says it will partner with existing battery manufacturers that can support the kind of high-throughput manufacturing big orders will require.

Think of it like bringing the fabless chip design technologies and business models to the battery industry, says Pereira.

Holy Grail already has $14 million in letters of intent with potential customers, according to Pereira and is expecting to close additional financing as it exits Y Combinator.

To date the company has been backed by the London-based early stage investment firm Deep Science Ventures, where Pereira worked as an entrepreneur in residence.

Ultimately, the company sees its technology being applied far beyond batteries as a new platform for materials science discoveries broadly. For now, though the focus is on batteries.

“For the low volume we sell direct,” says Pereira. “While on high volume production, we will implement a pilot line through the system… we are able to do the research engineering with the small ones and test the big ones. In our case when we have a cell that works, it’s not something that works in a lab it’s something that works in the final cell.”

Nio electric vehicles sales took a hit as it scrambled to handle battery recall – gpgmail


Nio delivered just 837 electric vehicles in July, a nearly 38% drop from the previous month that was largely caused by a voluntary recall of its high-performance ES8 SUV.

The Chines automotive startup issued a voluntary recall in June of nearly 5,000 ES8 SUVs after a series of battery fires in China and a subsequent investigation revealed a vulnerability in the design of the battery pack that could cause a short circuit. The recall affected a quarter of the ES8 vehicles sold since they went on sale in June 2018.

Nio was able to complete its recall for the 4,803 ES8s by prioritizing battery manufacturing capacity for this effort, which significantly affected our production and delivery results, NIO founder, chairman and CEO William Li said Monday in a statement.

“On the positive side, we completed the ES8 battery recall in approximately half the time compared to our original timeline,” Li said, adding that the customer confidence is returning. “Looking ahead, with battery capacity allocation back to normal, we will accelerate deliveries and make up for the delivery loss impacted by the recall.”

Nio expects August to be a “much stronger month” with a target to deliver between 2,000 and 2,500 vehicles, according to Li. That’s a considerable jump from what Nio has been able to achieve in the past several months, even without the added battery recall problem.

Nio delivered 1,340 vehicles in June, 1,089 in May and 1,124 in April. As of July 31, 2019, aggregate deliveries of the Company’s ES8 and ES6 reached 19,727 vehicles, of which 8,379 vehicles were delivered in 2019.

Deliveries of the ES8 initially surpassed expectations, but they have since slowed in 2019. Now, Nio will have to double deliveries in August to meet its target.

Other factors, and ones that might prove more chronic, also affected delivery numbers in July. Li noted that anticipated reductions in EV subsidies and macroeconomic conditions in China such as a decline in passenger vehicle sales and the U.S.-China trade conflict as other causes.

The souring economic picture in China has already prompted Nio to cut its workforce by 4.5%, shift its vehicle production plans and reduce R&D spending. Nio reported in May a loss of $390.9 million in the first quarter from a slowdown in sales that was primarily driven by the EV subsidy reduction in China and macroeconomic trends in the country that have been exacerbated by the U.S.-China trade war, Li said at the time.
