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.
Solid-state batteries is a key innovation area in batteries
Solid-state batteries are a type of rechargeable battery in which both the cathode and anode are made of solid-state materials, including solid electrolytes. Solid-state batteries are preferred over conventional batteries due to their higher energy density, longer cycle life, and inherent safety features.
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 solid-state batteries.
Key players in solid-state 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’.

Murata Manufacturing is one of the top patent filers in solid-state batteries. The company has developed a new electrolyte for electric vehicles (EVs). The composite material, made of lithium salt, solid polymer, and ceramic filler, offers stability, non-flammability, and a wider electrochemical window. This could lead to improved performance, safety, and cost-effectiveness, potentially accelerating EV adoption. Some other key patent filers in this space include LG and Sony Group.
In terms of application diversity, Solvay leads the pack, while Centre National Research Scientific and Semiconductor Energy Laboratory stood in the second and third positions, respectively. By means of geographic reach, Umicore held the top position, followed by Semiconductor Energy Laboratory and Emw Energy.
