![]() The EU has already offered grants to several battery makers in different countries. That means the government can offer subsidies for auto makers investing in battery technology. The European Union has declared battery cell production to be an important project of common European interest. "Those solid-state batteries will be more expensive when they start to be industrialized because the production scale will be much smaller," he told DW. Tim Wicke, a researcher at the Fraunhofer Institute for Systems and Innovation Research, said that demand for these new batteries will be limited to niche markets at first. Cracks can form and grow in these batteries, Lorenz Olbrich, a doctoral student in Materials Science at Oxford University told DW, "hence providing a shorter lifetime for the battery." Scalability still in questionĪlthough the solid-state battery is thought to be lighter, more powerful with shorter charging times and safer, experts remain skeptical about the mass production costs and how much consumers will need to pay for it. They've also signed partnerships with companies like Prologium, a Taiwanese developer and manufacturer of solid-state batteries.īut alongside the numerous advantages, the solid-state battery is also thought to have a shorter battery life. Mercedes Benz, for its part, plans to go all-electric by 2030. In late July, the company's stock soared on the news that it was working with a partner in the automotive industry on a potential launch of its first commercial product. So important is the solid-state battery technology that Volkswagen has become the biggest shareholder in QuantamScape, a solid-state battery company founded in 2010. Toyota, the world's second-largest car manufacturer, has said it plans to produce cars with solid-state batteries by 2025.ĭue to a higher energy density, the solid-state battery will power the car over longer distances, hence improving range, a key issue for both consumers and manufacturers when it comes to EVs. In early July, the Japanese carmaker said it had simplified the production process for materials used to make them. Tests in labs both in Japan and Europe have shown much potential in the battery, with Toyota recently announcing a breakthrough with the solid-state battery. The absence of a flammable liquid electrolyte reduces the risk of fire, making the battery safer compared to the liquid-state battery. This makes it possible to do away with the heavy separator component needed to keep the positive electrode from coming into contact with the negative electrode. With solid-state batteries, scientists have managed to replace this liquid electrolyte with a solid electrolyte. Lithium batteries rely on a liquid electrolyte solution, which allows lithium ions to move as needed for the battery to function. Until now, Tesla and most other EVs have relied on lithium batteries, which require frequent recharging Image: Bernd Feil/MiS/IMAGO New batteries could solve electric vehicle woes The lead acid, nickel metal hydride and lithium ion batteries are all used in the auto industry, particularly the lightweight lithium batteries. Tesla relies heavily on lithium batteries for their electric cars. Secondary batteries, meanwhile, allow for chemical reactions to be reversed through voltage application, making them rechargeable. The most popular type is the Alkaline battery, widely used in low-power standalone devices. They provide steady energy throughout their lifespan but cannot be reversed to produce more energy. Primary batteries, also known as one-use batteries, cannot be recharged. There are two main kinds of batteries: primary and secondary. ‘'I think the battery is the greatest innovation of the 21st century and it's changing our world totally," Professor Ferdinand Dudenhoeffer, director at the Center for Automotive Research in Duisburg, Germany, told DW. From single-use to solid-stateįrom simple, single-use cells like the AA and AAA to rechargeable battery cells like those used in EVs, battery usage has also evolved significantly since they were invented in the 1800s. Solid-state batteries could offer this advantage over the batteries currently in use, along with higher energy density and faster charging. The development of the electric vehicle (EV) has created a demand for automobile batteries with greater driving range. ![]() With the auto industry looking to cut carbon emissions by doing away with the combustion engine, the battery has been the go-to power source to replace petrol, a fossil fuel. But they're also throwing significant money into research and development of the so-called solid-state battery. Mercedes, BMW and Volkswagen are all currently employing the use of standard Lithium batteries. All major European car makers have embraced batteries as they scramble to meet deadlines for EU regulation 2035 of phasing out the combustion engine.
