The automotive industry continues to be a hotbed of innovation, with activity driven by solid-state batteries that are portable, strong, and long-lasting, and growing importance of technologies such as electromechanical actuators, sensors, electrification, connected and autonomous vehicles. In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Environmental sustainability in Automotive: Silicon-air batteries

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity. 

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have. 

290+ innovations will shape the automotive industry 

According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over 619,000 patents, there are 290+ innovation areas that will shape the future of the industry. 

Within the emerging innovation stage, EV discharge prediction, fuel cell ion exchange membranes, and hydrogen ICE fuel tanks are disruptive technologies that are in the early stages of application and should be tracked closely. V2G smart metering, silicon-air batteries, and zeolites for exhaust filtering are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are HEV propulsion systems and wind-powered vehicles, which are now well established in the industry. 

Innovation S-curve for environmental sustainability in the automotive industry 

Silicon-air batteries is a key innovation area in environmental sustainability 

Silicon has long been a popular choice for lithium-ion battery anodes due to its energy capacity being up to ten times greater than that of the widely used material, graphite. Lithium-ion batteries containing silicon have a 20%-40% higher energy density.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 60+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of silicon-air batteries. 

Key players in silicon-air batteries – a disruptive innovation in the automotive industry  

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators. 

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
