Advanced Li-ion battery cells & packs

Advanced Li-ion refers to silicon and Li-metal anodes, solid-electrolytes, high-Ni cathodes and various cell design factors. Given the importance of the particular electric vehicle market, specifically battery electric cars, in determining battery demand, IDTechEx says it believes Li-ion is forecast to maintain its dominant position. However , gradual improvements to cathodes, anodes, cell style and energy density are key. According to the recent IDTechEx report, “ Electric Cars 2023-2043 , ” up to 400Wh per kg battery cells will be inside mainstream markets by 2030.


Innovation is also happening at the pack level. Several materials are usually required in order to assemble a battery pack, including thermal interface materials, adhesives, gaskets, impregnation, potting, fillers and more. A general trend towards larger cell form factors and non-modular cell-to-pack electric battery designs is underway, reducing the number of connections, busbars and cables between cells plus modules.

Power electronics

In automotive power electronics (inverters, onboard chargers, DC-DC converters), key advancements are being made to improve powertrain efficiency, allowing for either battery pack capacity reduction or improved range. One associated with the key avenues to achieving greater efficiencies is the transition in order to silicon carbide MOSFETs and high-voltage automobile platforms at or above 800V. Indeed, Renault, BYD, GM, Hyundai and others have announced 800V vehicle platforms that will adopt silicon carbide MOSFETs in their power electronics through 2025.


IDTechEx says the particular transition presents fresh challenges for energy module package materials, as higher switching frequencies, increased power densities and improved operational temperatures are demanded, all while maintaining a 15-year service life. The report finds that will 800V platforms and SiC inverters will certainly rise to at least 10% of the market by 2030. As the power density of semiconductor chips increases exponentially, new double-sided cooling designs, copper wire bonds and lead frames will enable the particular trend.

Electric powered motors

Electric motor markets are still evolving with new designs improving strength and torque density plus more considerations around the materials used. IDTechEx believes developments such as axial flux motors and numerous OEMs may eliminate rare earth materials altogether.


There are several essential performance metrics for electric motors. Energy and rpm density enables improved driving dynamics in a smaller and lighter bundle, with weight and space at the premium in EVs. Another critical area is drive-cycle efficiency. Improving efficiency means less associated with the precious energy stored in the battery is wasted when accelerating the automobile, leading to an improved range from the same battery power capacity. Due to the many different considerations within motor design, the EV market has adopted several other solutions, including permanent magnet, induction and wound-rotor motors.

IDTechEx thinks that while motors will remain dominated by permanent magnets, there may be opportunities for magnet-free variants as cost plus sustainability come to the forefront in the particular coming years.


Fuel Cells

Opportunities for fuel cells in car marketplaces are limited, although markets are still growing, underpinned simply by government support. The deployment of fuel cells within vehicles is not a new concept. Major OEMs, including Toyota, Ford, Honda, GM, Hyundai, Volkswagen, Daimler and BMW, have invested large sums over the past 30 many years in advancing the technology. For passenger cars, a considerable amount of effort and expense has gone into developing fuel tissues. Still, within 2022 only two major OEMs, Toyota and Hyundai, have FCEV cars in production plus fewer than 20, 000 FCEVs were sold in 2021.

Fuel cellular vehicle deployments face considerable challenges, which includes decreasing the cost of fuel cell system components and rolling out sufficient hydrogen refueling infrastructure. Also essential will be the availability of low-cost ‘green’ hydrogen, produced by the electrolysis associated with water using renewable electricity, which analysis in the particular new IDTechEx report highlights will be vital to FCEVs delivering the environmental credentials on which they are being sold.



‘Autonomous vehicle’ (AV) is a good umbrella term for the six levels defined by the SAE. Today, most new cars are arriving with the option of level 2 functionality and the particular industry will be technically ready for degree 3 once regulatory hurdles clear.

In recent years, vast improvements to autonomous vehicle technologies such because radar, lidar, HD cameras and software have propelled ‘Robo-Taxis’ in order to the cusp of marketplace readiness. In certain scenarios, level 4 autonomy is commercialized in 2022, with Cruise and Baidu introducing initial services in the US and China, respectively. IDTechEx forecasts how these services will come to dominate within twenty years. Overall, IDTechEx reviews autonomous vehicles becoming the massively disruptive technology that will proliferate at a rate of up to 47% to transform the auto market over the particular next two decades.
