SAFT America is developing an LMO/LTO lithium ion cell design for vehicle application in collaboration with U.S. Advanced Battery Consortium (USABC) . 

The first two targets set by SAFT are meeting cold crank requirements at -30°C  set by USABC and solving gassing issues.

Different electrode formulations, electrolytes and cell designs have been investigated to successfully pass cold crank testing. A specific non carbonate electrolyte satisfies cold crank requirements down to 15% state of charge.  Moreover new electrode formulations may potentially help meet cold crank requirements using carbonate electrolytes.

In addition, SAFT will share the outcome of recent electrolyte screening, cycle life improvement and impedance growth reduction experiments. From the results, the gassing mechanism of LTO can be inferred and will be discussed.
