A123’s Nanophosphate™ technology is designed to be highly abuse tolerant while meeting the most demanding customer requirements of power, energy, operating temperature range, cycle life and calendar life.

Multiple layers of protection are employed at the chemistry, cell and pack level to achieve an energy storage solution with superior safety and abuse tolerance compared to metal oxide lithium ion.

The following features are incorporated to enhance abuse tolerance at the cell level:

• Patented fast charge capability that avoids lithium plating at the negative electrode while maintaining high energy density, used across the range of Nanophosphate technology
• The industry’s first dual plate laser-welded aluminum cell construction, used in our larger cells to provide extreme mechanical robustness and hermeticity with low weight
• Advanced vent technology to safely release gas pressure buildup, including dual vents in larger cylindrical cells for transportation applications
• Center pin construction designed to allow efficient gas release and avoid internal mechanical deformation under extreme abuse
• Depending on the cell type and application requirements other passive components may be used including a current interruption device or a thermally activated shutdown separator
