Key players in graphene 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’.
Toray Industries is the leading patent filer in the graphene batteries innovation area. The company has successfully developed an ultra-thin graphene dispersion solution with excellent fluidity, electrical conductivity, and thermal conductivity. It has developed a technology that uses cheap graphite materials to make very thin, high-quality graphene. LG, PPG Industries, Sekisui Chemical, and Fraunhofer-Gesellschaft are some of the other key players in graphene batteries innovation.
In terms of application diversity, Toray Industries held the top position, while LG and PPG Industries stood in second and third positions, respectively. By means of geographic reach, Fraunhofer-Gesellschaft leads the pack, followed by PPG Industries and NanoXplore.
