How Quantum Computers Can Make Batteries Better

IONQ QUANTUM COMPUTING BATTERIES LITHIUM-AIR BATTERIES HYUNDAI ELECTRIC VEHICLES
Hyundai is now partnering with startup IonQ to see how quantum computers can design advanced batteries for electric vehicles, with the aim of creating the largest battery-chemistry model yet to be run on a quantum computer, the companies announced yesterday.
A quantum computer with high enough complexity—for instance, enough components known as quantum bits or “qubits”—could theoretically achieve a quantum advantage where it can find the answers to problems no classical computer could ever solve. In theory, a quantum computer with 300 qubits fully devoted to computing could perform more calculations in an instant than there are atoms in the visible universe.
The nearest-term app for quantum computers may be chemistry—for instance, simulating molecules to see which ones might prove useful drugs. “Quantum computers are naturally suited for modeling molecular behavior because both are systems governed by quantum mechanics,” says Peter Chapman, CEO and president of Maryland-based IonQ. Since quantum computers can model chemistry more accurately than classical computing, “it becomes possible to ensure that one is extracting maximum efficiency and eliminating sources of potential waste.”
Now IonQ aims to use quantum computing to analyze and simulate the structure and energy of lithium compounds for Hyundai’s batteries, including lithium oxide in lithium-air batteries. “Lithium-air batteries have a higher energy density than lithium-sulfur batteries and thus have more potential power and capability,” Chapman says.
In the new partnership, IonQ will develop new variational quantum eigensolver algorithms optimized for investigating lithium chemistry. These kinds of algorithms are often used in quantum chemistry to, for instance, model a molecule’s ground state, the one in which it has the least amount of energy. Variational quantum eigensolvers are actually hybrid algorithms, where classical computers do much of the work while quantum processors solve the part of the problem that would prove difficult for conventional machines to handle.
IonQ will join the classical and quantum computers in this work over the cloud. This includes IonQ’s latest quantum computer, “which recently outperformed all other devices tested in a series of benchmarking tests run by industry consortium QED-C and which is currently in private beta,” Chapman says.

Whereas Google, IBM, Amazon and others often use qubits based on superconducting loops, IonQ uses qubits based on electromagnetically trapped ions. Superconducting loops are compatible with conventional microchip technology, but trapped ions may offer advantages such as resistance to errors.
The partnership aims to create the most advanced battery chemistry model yet developed on quantum computers, measured by the number of qubits and quantum gates, the quantum computing version of the logic gates that conventional computers use to perform computations.
“The team plans to harness at least 12 qubits and over 100 gate operations for the project,” Chapman says. In comparison, a Daimler-IBM partnership using quantum computing to develop next-generation lithium-sulfur batteries used only four qubits, and no other commercial projects have published results yet, he notes.
Carmakers are increasingly looking into quantum computing “because it is naturally applied to a revolution taking place across the industry—the development of electric vehicles,” Chapman says. “There is enormous incentive to make a better, less expensive battery, and so it makes sense that forward-thinking companies like Hyundai are putting quantum in their tool kit.”
The companies noted this work aims to improve the cost, durability, capacity, safety, and charging behavior of lithium batteries, which are often the most expensive components of electric vehicles. “Electric vehicles are an important part of the global movement toward reducing our collective carbon footprint,” Chapman says. “It’s very meaningful to be partnering with Hyundai to advance science that will help make them more commonplace.”
Beyond chemical analysis for battery materials, quantum computing could also help explore fuel-cell technologies and material durability, Chapman notes. In addition, “quantum machine learning applications could be used to improve training time for autonomous vehicles and solve simple problems in predictive maintenance, warehousing, and more,” he says.
“Longer-term, more complex optimization problems such as multichannel logistics and routing are on automakers’ R&D slates,” Chapman adds. “For instance, Volkswagen has been exploring quantum computing in a variety of applications for several years, first looking at how best to optimize the routing of buses and vans in traffic using quantum hardware and quantum-inspired techniques. More recently, they’ve been looking at optimizing the distribution network of charging stations.”
All in all, “I hope this partnership makes clear that quantum is not some far-off concept with no present practical application,” Chapman says. “If you choose the right partner and pick the right problems, there is impactful work that can be done right now.”

IonQ and Hyundai Motors announced a new partnership designed to use the power of quantum computing to build better electric car batteries. The companies expect the research to benefit Hyundai's automotive lithium batteries by making improvements to the charge and discharge cycles of the devices as well as their durability, capacity and safety.
The team will develop new variational quantum eigensolver (VQE) algorithms to study lithium compounds and their chemical reactions. The IonQ/Hyundai project plans to run a battery chemistry model to simulate 14 electrons of dilithium oxide.
A VQE algorithm runs partly on a classical computer and partly on a quantum computer. As the IBM Q team explained: "A classical computer varies some experimental parameters that control the preparation of a quantum state, and then a quantum computer prepares that state and calculates its properties."
The project team will have access to all quantum computers commercially available at IonQ, including the latest system which is currently in private beta. This version of the hardware recently outperformed all other devices tested in a series benchmarking tests run by industry consortium QED-C, according to Peter Chapman, president and CEO of IonQ.
"In terms of recent technological milestones, the system uses the advanced double-individual gate laser system, where each ion is being hit by two individual laser beams," he said.
TaeWon Lim, executive vice president and head of the Fundamental Material Research Center at Hyundai Motor Group, said in a press release that the company is stepping into the quantum era and developing more effective battery power.
"This creative collaboration with IonQ is expected to provide innovation in the development of basic materials in virtual space for various parts of the future mobility," he said.
Chapman said in a press release that quantum chemistry solutions can address climate change.
"Battery efficiency is one of the most promising emerging areas where quantum computing can make a difference," he said.

Chapman sees many use cases for quantum computing in the auto industry as Hyundai and others shift their focus from being car manufacturers to being transport and mobility providers.
"Volkswagen, Daimler, Bosch, BMW, and more have already invested in research across a variety of application areas," he said. "Volkswagen has been exploring quantum computing in a variety of applications for several years, first looking at how best to optimize the routing of buses and vans in traffic using quantum hardware and quantum-inspired techniques, and more recently, they're looking at optimizing the distribution network of charging stations."
The research from the battery project also could be used to improve fuel cell technologies and material durability, Chapman said, as well as optimization challenges.
"Quantum machine learning applications could be used to improve training time for autonomous vehicles, and solve simple problems in predictive maintenance, warehousing and more," he said. "Longer-term, more complex optimization problems such as multichannel logistics and routing are on automakers' R&D slates."
This quantum partnership supports Hyundai's Strategy 2025 goals, which are designed to increase sales of electric vehicles and address climate change. The plan has four focus areas: electric vehicles, urban air mobility, autonomous driving technology and hydrogen fuel cells. The Strategy 2025 goals include selling an all-electric lineup by 2040 and developing a hydrogen fuel cell ecosystem.
Hyundai started selling electric vehicles in 2008 and brings expertise in lithium batteries to the new partnership, while IonQ brings quantum skills and hardware. IonQ has worked with other partners to apply quantum computing to chemistry problems. In March 2021, IonQ described research with Dow and 1QBit to simulate complex molecules and chemical compounds. The researchers used the principle of problem decomposition to "reduce the number of qubits required to simulate the electronic structure of a large model chemical system."
This means fewer qubits–up to a factor of 10–are needed to achieve the same level of accuracy compared with solving the problem without breaking it down into smaller parts. The paper, "Optimizing Electronic Structure Simulations on a Trapped-ion Quantum Computer using Problem Decomposition," was published in February 2021.
IonQ uses a trapped-ion design in its quantum machines. IonQ's quantum systems are available through direct API access, Amazon Braket, Microsoft Azure and Google Cloud.
