Automotive Cells, a venture between Mercedes-Benz, Stellantis, and TotalEnergies, is developing SSBs with Taiwanese ProLogium Technology.Īlready a competitor: The semi-solid batteryĪlong with SSBs, semi-solid state battery technology has been developed for a while, led by M24.QuantumScape's SSB prototype can retain over 80% of its capacity after 800 cycles. The company has agreements with six automakers. Volkswagen is backing another U.S. startup, QuantumScape, to make SSBs available for EVs.According to Reuters, Ford, BMW, and Hyundai have invested in U.S.-based startup Solid Power.Nissan plans to power the legendary Leaf with SSBs, aiming to start mass production by 2028.Another model, ES6, is predicted to reach the 930 km range with the same battery. Its subsidiary, WeLion, delivered the first SSBs this summer, with 150-kWh SSBs to power NIO ET7. Chinese EV maker NIO adopted an SSB strategy in 2021.The French auto giant expects to double the range of Megane E-Tech 280-mile (450 km). Renault has partnered with Airbus to develop SSBs, aiming to start manufacturing by 2030.The two hold the most patents in SSBs, Toyota having over 1,330 and Panasonic 445. Toyota is working on SSBs with Panasonic, aiming to start using the technology by 2027, providing a range up to 900 miles (1,440 km).Unsurprisingly, almost all major automakers are interested in new-generation batteries, and some are already working heavily on SSBs. With many OEMs interested in the technology, the average range of an EV is expected to reach up to 1,000-1,200 km and will be able to charge up in just 10 minutes, according to Toyota. SSBs will significantly increase the range of EVs, offering double the mileage with almost half the price compared to li-ion batteries. Most importantly, the emergence of SSBs will signal the definitve end of internal combustion engines (ICEs), expected to become useless when li-ion and SSB batteries become widely adapted, predictably in the early 2030s. SSBs have an inevitable importance for EVs, prepared to kick open a new era in the industry. Used in various devices such as smart watches and pacemakers, SSBs have required a thorough process to become ready for the EV industry. Additionally, an SSB using glass electrolytes can perform in temperatures as low as -20☌. Braga, 'glass solid-state batteries' can offer three times the energy density by using an alkali-metal anode (lithium, sodium or potassium) and a longer life cycle. Goodenough, the co-developer of li-ion battery technology, and researcher Maria H. The life cycle of SSBs is also much longer, with some SSBs showing the potential of sustaining 90% of capacity after 5,000 cycles, according to Topspeed (for the conventional li-ion, the life span is between 2,000-3,000 cycles, but lithium iron phosphate batteries, LiFePO4 or LFP, take this up to 4,000).Īccording to John B. Solid electrolyte in the battery ensures performance under low temperatures.Composing higher energy density battery pack without using more space.Enhanced use of space thanks to less materials.No risk of explosion, thus reducing the safety materials needed.Use thin layers of solid electrolytes carrying lithium ions.SSBs have critical differences compared to li-ion batteries: SSBs offer improved stability with a solid structure and much better safety thanks to maintaining their form even when damaged. Compared to li-ion batteries, an SSB uses a solid electrolyte, which also has the role of a separator. What is a solid-state battery?Ī lithium battery consists of a cathode and anode, separated by a liquid electrolyte, allowing electrons to pass through it, thus allowing energy generation for EVs. Could a different technology offer improvements in both price and range? Cue solid-state batteries (SSBs), and their cousin, semi-solid-state batteries (SSSBs). Despite the influx of lower-priced Chinese EV models, the volume-weighted average price (VWAP) of EVs is projected to be around $52,800 for the whole of 2023, says Statista.Ī large part of the price of an EV is the battery. The price for a new plug-in hybrid electric vehicle (PHEV) remained stable at $51,000. Price is also a factor: why switch to electric if that comes with range anxiety and a higher sticker price?Īccording to the International Energy Association, the global average for a new battery-electric vehicle in 2021 was just over $36,000 - down 7% over 2020. These include the glaring lack of public charging infrastructure, and the underwhelming performance of current li-ion battery technology. Will solid-state batteries be able to do that?Įspecially prevalent among 'new' electric vehicle (EV) drivers, range anxiety is a problem with many causes. While performance has improved and cost is going down, the advances have not managed to eliminate range anxiety. Decades of hard work has gone into improving lithium-ion (li-ion) battery technology.
