IDTechEx discusses technology development to drive long-term adoption of electric vehicles

BOSTON, June 14, 2021 / PRNewswire / – The resilience of global electric vehicle (EV) sales in 2020 has raised some optimism about the maturing state of the electric vehicle market. However, sales are still primarily supported by government policy, and improvements in the cost and performance of Li-ion cells and packs, not to mention other aspects of vehicle or network infrastructure, are needed. for widespread adoption.

For example, there is a clear trend towards higher nickel NMC and NCA cathode materials for battery electric cars (BEVs) to help improve the energy density of Li-ion batteries and, therefore, the EV range, but these cathodes with high nickel content not be universally optimal. Segments such as buses or forklifts can benefit from the safety and low cost of the LFP. There has also been renewed interest in using LFP for cars, driven by concerns about sustainability and the supply of critical metals, including cobalt, nickel and even manganese. Tesla’s Model 3 in China uses the LFP, while Volkswagen and Renault have announced the possibility of using the cathode for entry-level models. In their “Lithium-ion Batteries for Electric Vehicles 2021-2031” market report, IDTechEx predicts that the market share of LFPs will increase to 15% by 2026, showing that despite the growing popularity of LFPs, NMC and NCA will retain the majority market share. Electric vehicle market as a whole.

While there is rightly a lot of discussion about the role of cathodes in improving the performance, cost and durability of Li-ion, a key area of ​​cell development that will help improve the performance, cost and durability of Li-ion. Li-ion energy density relates to the material of the anode. Namely, the development of silicon and lithium metal anodes, the latter often combined with a solid electrolyte which can provide additional safety benefits. Lithium metal and silicon offer their own advantages and disadvantages, but both can provide significant improvements in gravity and volumetric energy density, and given the importance of the EV range, many automakers have come together. to lithium-metal / semiconductor technology and silicon anode developers. Coupled with developments in cell and cathode design, IDTechEx estimates that commercially available cells for electric vehicles will offer 30-40% improvements in gravity and volumetric energy density by the end of the year. decade, thus helping to increase the attractiveness of electric vehicles to the wider market. .
