Whether it<\/span> is<\/span> photovoltaics or fusion, sooner or later<\/span> human civili<\/span>s<\/span>ation must turn to renewable energies. This is deemed inevitable considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. As such, <\/span>research has been pursued <\/span>in order to<\/span> develop alternative sources of energy, <\/span>such as quantum charging technology. <\/span><\/span>\u00a0<\/span><\/p>\n The extensive <\/span>research and demand<\/span> in renewables <\/span>ha<\/span>s<\/span> been accompanied by gradual societal changes as the world <\/span>has <\/span>adopted new products and devices running on renewables. The most striking change as of recently is the rapid adoption of <\/span>EVs<\/span>. While they were hardly seen on the roads even <\/span>10<\/span> years ago, now millions of <\/span>EVs<\/span> are being sold annually<\/span>, making t<\/span>he <\/span>EV<\/span> market is one of the most rapidly growing sectors<\/span>.<\/span><\/span>\u00a0<\/span><\/p>\n Unlike traditional cars, which derive energy from the combustion of hydrocarbon fuels, EVs rely on batteries as the storage medium for their energy. For a long time, batteries had far lower energy density than those offered by hydrocarbons, which resulted in very low ranges of early EVs.<\/p>\n However, gradual improvement in battery technologies eventually allowed the drive ranges of EVs to be within acceptable levels in comparison to gasoline-burning cars. It is no understatement that the improvement in battery storage technology was one of the main technical bottlenecks which had to be solved in order to kickstart the current EV revolution.<\/p>\n However, despite the vast improvements in battery technology, today consumers of EVs face another difficulty \u2013 slow battery charging speed. Currently, cars take about 10 hours to fully recharge at home. Even the fastest superchargers at the EV charging stations<\/a> require up to 20-40 minutes to fully recharge the vehicles. This creates additional costs and inconvenience to the customers.<\/p>\n To address this problem, scientists looked for answers in the field of quantum physics. Their search has led to the discovery that quantum technologies may promise new mechanisms to charge batteries at a faster rate. Such concept of a \u2018quantum battery\u2019 has been first proposed in a seminal paper published by Alicki and Fannes in 2012. It was theorised that quantum resources, such as entanglement<\/a>, can be utilised to vastly speed up the battery charging process by charging all cells within the battery simultaneously.<\/p>\n This is particularly promising as modern large-capacity batteries can contain numerous cells. Such collective charging is not currently possible in classical batteries, where the cells are charged in parallel and independently of one another. The advantage of this collective versus parallel charging can be measured by the ratio called the \u2018quantum charging advantage.\u2019<\/p>\nIs a quantum battery possible?<\/h3>\n
