Electrode active materials is a key innovation area in batteries
Electrode active materials in Li-ion batteries refer to the materials used in the electrodes of these batteries to store energy through the intercalation and de-intercalation of lithium ions during charging and discharging. These materials need to have high energy density, excellent cycling stability, high-rate capability, and low cost to improve the overall performance and reduce the cost of Li-ion batteries.
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 electrode active materials.
Key players in electrode active materials – 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’.
