Johnson Controls Develops an Improved Vehicle Battery, Works to Cut Battery Costs in Half

Project Overview
Impact: Improving vehicle batteries and their manufacturing costs.
Johnson Controls is working to increase energy density of vehicle batteries while reducing manufacturing costs for lithium-ion battery cells.
Locations: Wisconsin
Partners: Johnson Controls
EERE Investment: $3.68 million
Clean Energy Sector: Sustainable transportationPDF

Johnson Controls’ Holland Technology Center in Milwaukee recently developed and built a new lithium-ion battery cell and accompanying system that substantially increases the energy density of plug-in electric vehicle battery cells. The company matched EERE’s investment and is using this technology to develop a standard, commercialized lithium-ion cell for plug-in electric vehicles. Johnson Controls is building on this success with a project underway to improve manufacturing processes that will reduce manufacturing costs for lithium-ion vehicle battery cells by 50%.

The Vehicle Technologies Office develops and deploys efficient and environmentally friendly highway transportation technologies that will enable America to use less petroleum. These technologies will provide Americans with greater freedom of mobility and energy security, while lowering costs and reducing impacts on the environment.
