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.
Silicon-air batteries is a key innovation area in batteries
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 390 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 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’.
Shin-Etsu Chemical is the top patent filer in silicon-air batteries. The company enables large EV customers to optimize anode materials and cell designs and produce EV battery packs required for commercial qualifications by providing access to dedicated pilot facilities. LG, Toyota Motor, Nexeon, and Umicore are some of the other leading patent filers.
In terms of application diversity, Shin-Etsu Chemical held the top position, while LG and Toyota Motor stood in second and third positions, respectively. By means of geographic reach, Hitachi leads the pack, followed by Printed Energy and Hydro-Quebec.
