The Advanced Technology Development Program is testing a second generation of lithium-ion cells, consisting of a baseline and three variant chemistries. The cathode composition of the Variant C chemistry was altered with an increase to the aluminum dopant and a decrease to the cobalt dopant to explore the impact on performance. However, it resulted in a 20% drop in rated capacity. Also, the Variant C average power fade is higher, but capacity fade is higher for the Baseline cell chemistry. Initial results indicate that the Variant C chemistry will reach end of life sooner than the Baseline chemistry.
