Introduction: Lithium-ion battery is the most dazzling generation in the battery world so far. Before that, lead-acid , cadmium nickel battery and nickel hydrogen hydrogen batteries have not achieved the achievements made by lithium-ion batteries. Lithium-ion batteries are all around us, including mobile phones, notebooks, smart watches, and electric car , etc. Now in static energy storage devices, they are also replacing lead-acid battery with a huge force.
We all want to use batteries with longer service life, faster charging time, larger capacity and lower cost. However, the complex electrochemical reaction in the battery theoretically makes these requirements only reach a certain optimization, and cannot be met in every aspect. The impact of chemical and material adjustment on electrochemical reactions is very complex, and existing computers are not enough to unlock these mysteries.
. The highly complex quantum computer contains the component of " qubit ", and can find answers to existing computers that cannot solve the problem. In theory, a quantum computer with 300 qubits can perform more calculations in a moment than atom in the visible universe.
Recently, Volkswagen Group and Toronto-based Xanadu Company (Xanadu), a Toronto-Canadian, have collaborated to develop advanced quantum algorithms to develop safer, lighter and more cost-effective battery materials. Their collaboration has achieved something, and they published an article in the journal Physics Review A, titled "Simulating key properties of lithium-ion batteries with a fault-tolerant quantum computer."

They used the created quantum algorithm to calculate the balanced battery voltage, ion mobility and thermal stability by simulating dilithium silicate.
Doctor Nikolai Ardey, head of the innovation department of Volkswagen Group, is very optimistic about the prospects of cooperation. He said: "Combining with the Paradise Company is like jumping on a speedboat and sailing to the next big thing: quantum computing may trigger a revolution in material science and optimization, which is the key capability to develop our internal battery expertise."
Volkswagen Group has always been the overlord in the fuel vehicle era, but in the transformation of electric vehicles, it is behind compared with Tesla and some electric vehicle manufacturers in my country. And they are also making improvements in many aspects and are unwilling to be behind Tesla.
"CamCellLab" official account believes that Volkswagen Group's ambition is to be a leader in quantum computing, and to use advanced technology to transform the most critical component of electric vehicles, power battery , and strive to regain its position in traditional fuel vehicles in terms of electric vehicles.
