The automotive industry continues to be a hotbed of patent innovation. Activity is driven by lightweight, long-lasting batteries and powerful solid-state batteries, and growing importance of technologies such as high energy density, flat voltage curves, and low self-discharge. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Batteries in automotive: zirconium electrode batteries.  Buy the report here.

According to GlobalData’s Technology Foresights, which uses over one million patents to analyze innovation intensity for the automotive industry, there are 300+ innovation areas that will shape the future of the industry. 

Zirconium electrode batteries is a key innovation area in batteries 

Zirconium‐based materials are emerging as potential candidates for developing the next generation of electric batteries. The first application of Zirconium sulphide (ZrS2) was as a potential lithium-ion battery electrode material. The electrochemical reactions of ZrS2 at various discharge depths were studied along with the structural changes of ZrS2 electrodes under various voltage windows. Reversible Li ion insertion and extraction was demonstrated by ZrS2 electrodes.

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 30+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of zirconium electrode batteries. 

Key players in zirconium electrode batteries – a disruptive innovation in the automotive industry  

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

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