According to GlobalData’s Technology Foresights, which uses over 619,000 patents to analyse innovation intensity for the automotive industry, there are 290+ innovation areas that will shape the future of the industry. 

Polymeric thin-film batteries is a key innovation area in electric vehicles 

A lithium-polymer battery (LiPo) uses lithium as one of the electrodes and solid polymer as the electrolyte. Commercially available LiPo batteries are hybrids, more properly known as lithium-ion polymer batteries, which can either contain gel polymer or liquid electrolyte in a pouch format.

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 90+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of polymeric thin-film batteries. 

Key players in polymeric thin-film 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’.
