Task 5, Batteries and Supercapacitors

Ongoing Tasks

Batteries and Supercapacitors

Completed Tasks

Programme of Work

Batteries and supercapacitors have the potential to transform EVs. Better and cheaper batteries for these vehicles are needed for market acceptance and consumer confidence in alleviating range anxiety. This was true in the late 1990s and still holds true today. This Task focused on information sharing on precompetitive exploratory research. Batteries have vastly improved in the past decade, but research still continues today in order to improve battery performance and reduce their cost.

Working Method

Task 5 was active during Phase 1 of IA-HEV and had concluded by 2000. The Task members worked with the organizational support of the Electrochemical Society (ECS) and held its meetings at the same time as ECS conferences. It organized two symposia on electric vehicle batteries and supercapacitors in conjunction with ECS, which published the proceedings. It also published two outlook reports that reported on the state of the art of different battery technologies, research priorities, and exploratory research being conducted in participating countries.


Participating countries were Canada, Austria, Italy, the Netherlands, Sweden, and the United States. ESTCO Energy Inc. of Canada served as the Operating Agent.

Current IA-HEV work

Task 10, Electrochemical Systems is actively exploring topics related to batteries and supercapacitors.
