Abstract: Provided are battery modules having two different types electrochemistry connected in series, which includes a plurality of a first cell, wherein the first cell includes an anode active material of graphite, Si, SiOx, or a blend thereof as a main component (“a GSi cell”), and at least one of a second cell, wherein the second cell includes an anode active material of a lithium titanate oxide or titanate oxide able to be lithiated as a main component (“a LTO cell”). Also provided are battery systems that include a plurality of the battery modules.
