People are slowly but surely embracing #electricvehicles (#EVs), but the pace of that transition still needs to accelerate for the world to hit its #netzero emissions target in 2050. Despite the exponential improvements of EVs, many drivers are still reluctant to leave behind the convenience of their petrol-powered #cars. Along with cost, concerns over a lack of charging stations and battery life were cited as the main barriers for US consumers buying an EV in an Ipsos survey last year. For car manufacturers, much of this comes down to the persistent restrictions on range and longevity of the incumbent #lithiumion (Li-ion) #batteries under EVs’ bonnets. However, a team of scientists at Harvard University believe they have taken an important step toward solving these quandaries. Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new “solid-state” battery that can charge in the time it takes to fill up a petrol tank, and endure 3–6 times more charge cycles than the typical EV battery. #solidstatebatteries have long been considered the holy grail for a widespread transition to electrified transportation, and the race to commercialise them has sped up in recent years. The likes of Toyota Motor Corporation and Volkswagen are developing their own versions, which they hope to get into vehicles by the end of the decade. With the boost of this latest innovation from Harvard, are solid-state batteries finally ready to live up to their hype?

Battery 101 To understand why that matters, it helps to know a little bit about how today’s batteries work. A typical EV battery is like a sandwich made of thin layers. First there’s what’s known as an anode, made of graphite. Suffusing the whole cell is a liquid electrolyte—like Gatorade, but it has lithium salts instead of sodium. Then a thin “separator”—picture something like saran wrap. Finally there’s a cathode, which is a mix of various metals, typically lithium, nickel, manganese and cobalt. When a battery is pushing electricity to the motor of a vehicle, lithium ions are moving between the anode and the cathode, through the plastic separator, which has microscopic holes just big enough for lithium ions to move through. It’s the physical movement of those lithium ions from one side of the battery sandwich to the other that generates current. In theory, a lithium metal anode can hold 10 times as many lithium ions as a graphite one. All other things being equal, this means the energy density of a battery using lithium metal in place of graphite could be up to 50% higher. The result, says Hu, is that automakers could someday offer affordable EVs that have the same range as today’s high-end ones. That would mean even entry-level EVs might go 300 miles on a charge. High-end EVs with bigger batteries could, in turn, set new records for range, besting current record-holders which top out at around 500 miles. Because the lithium metal in SES AI’s batteries replaces just one part of the battery cell, it can be incorporated into existing assembly lines. Currently, there are two dominant types of batteries for EVs, one optimized for high-end vehicles, and the other for lower-cost ones such as Tesla’s Model 3 and the coming tidal wave of affordable Chinese EVs. SES AI’s lithium metal technology works in both.
