### Specific Mentions
[Phasecraft](https://www.phasecraft.io/), one of the UK’s emerging quantum software start-ups will use quantum technology to overcome limitations in battery material designs and help predict their performance. This could break new ground in battery development across sectors from large-scale energy storage and high-performance electric vehicles, as well as lead to the development of more powerful battery devices.
[Hyundai x IONQ on Lithium Air Batteries](https://spectrum.ieee.org/lithium-air-battery-quantum-computing#toggle-gdpr)
- creating the largest battery-chemistry model yet to be run on a quantum computer
- 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
- Becuase 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.”
- 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](https://spectrum.ieee.org/lithium-air-batteries-battery-news). “Lithium-air batteries have a higher energy density than lithium-sulfur batteries and thus have more potential power and capability
- improve the cost, durability, capacity, safety, and charging behavior of lithium batteries, which are often the most expensive components of electric vehicles.
- 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.
[Daimler x IBM on Lithium Sulphur Batteries](https://www.ibm.com/blogs/research/2020/01/next-gen-lithium-sulfur-batteries/)
- Used a quantum computer to **model the dipole moment** of three lithium-containing molecules, which brings us one step closer the next-generation lithium sulfur (Li-S) batteries that would be more powerful, longer lasting and cheaper than today’s widely used lithium ion batteries.
- Simulating molecules is extremely difficult but **modelling them precisely** is crucial to discover new drugs and materials.
- quantum computers will help them design next-generation lithium-sulfur batteries, because they have the potential to compute and precisely simulate their fundamental behavior.
