For decades, scientists have wondered what to do with the fluid in a lithium-ion battery. These electrolytes are key to how the battery works, shuttling ions from one end of the cell to the other. But it’s also cumbersome, adding weight and bulk that limits how far an electric vehicle can go on a charge — on top of that, it can catch fire when the battery is short. A perfect repair would be to replace the liquid with a solid – ideally a mild and airy one. But the trick is in making the switch while maintaining all the quality that the battery shouldn’t. A solid-state battery should not only send you farther on each charge, it should also run faster and work in a variety of weather conditions. Getting everything right at one time is the most difficult question in materials science.
In recent months, startups that work on solid-state batteries have made steady progress for that purpose. Little battery cells that once sputtered after being charged will grow to be bigger and longer. There’s still a way to get to the cells that are ready on the way, but progress sets the next challenge: Once you’ve built enough batteries in severe laboratory conditions, how do you build millions of them quickly? “These companies need to have a big mindset change, from being an R&D company to a manufacturing company,” said Venkat Srinivasan, director of the Argonne Collaborative Center for Energy Storage Science. “It’s not that simple.”
In recent weeks, Solid Power, among the larger funded of solid-state companies, has launched a pilot route in Colorado that hopes will answer that question. At full capacity, it will produce 300 cells per week, or about 15,000 per year. That’s a trickle compared to the millions of cells that are produced each year by gigafactories, and until then it still takes months of equipment and processes. But the goal, according to CEO Doug Campbell, is to start sending cells to car manufacturers such as BMW and Ford for automotive testing by the end of the year.
Once the car manufacturer is happy with how the battery is on the road, the company plans to send the baton to one of the battery partners that has a gigafactory, such as the Korean battery behemoth SK Innovation. According to Campbell, it should be simple. Solid Power has designed what he describes as a uniquely manufacturable “feel” solid-state design that allows battery makers to reuse existing processes and devices designed for lithium-ion batteries. “In an ideal world, this is the last cell production line that is operated by Solid Power,” he said of the Colorado facility.
In principle, it makes sense. The battery is a battery. Like their liquid-filled cousins, solid-state batteries require an anode, cathode, and multiple means for ions to migrate between the two. That’s where the electrolyte comes in. But it is not easy to make something that is porous to ions, yet solid enough not to crack. Researchers have spent years searching for suitable materials, eventually establishing a number of ideas that include ceramics and plastic polymers. But not all of them are easy to make. Some are incredibly expensive, responsible for falling apart when they are made or when they are slotted between the electrodes; others are softer and more pliant, but cannot be exposed to moisture. Plus, battery scientists don’t have much practice producing the various precursor materials needed to make them. history just doesn’t exist.
The second problem is the anode. The holy grail for solid-state involves converting up the anode from typical graphite to lithium metal. Pair it with solid electrolytes and it likes great energy. The problem is the form of lithium metal. Battery manufacturers usually work with powdered materials for anodes and cathodes that can be rolled as a pulp. But lithium works best as a thin, free-standing foil — in Solid Power’s case, it’s 35 microns thick. “They have the consistency of wet tissue paper,” Campbell said. “And as you can imagine when you make material kilometers literally, it becomes difficult.”
