Which companies are patenting Li-on battery technology?

The first wave of Li-ion batteries revolutionised consumer electronics in the 80s. Now, the increasing need for batteries in electric vehicles, mobile phones and solar cells means the global market for Li-ion batteries is growing rapidly. Analysts estimate the global Li-ion battery market will exceed 90 billion USD by 2025.

The vast majority of Li-ion battery manufacturing takes place in Asia as a result of the ready availability of graphite – a graphite anode being an essential component a Li-ion battery. Asia is also a key market driving the demand for Li-ion batteries, as the Chinese government is backing electric vehicles (EVs) as part of the solution to its growing pollution problem. 

Developing batteries for electric vehicles poses specific challenges as consumers demand reliable, long lasting, and light weight power sources to enable them to travel further than ever before on a single charge. Which companies are developing innovative Li-ion battery technology? Which approaches are they taking, and how is the innovation landscape evolving? This intellectual property report tracks how the technologies and the patents protecting them are developing.
