COMBINATORIAL CHEMISTRIES FOR MATCHING MULTIPLE BATTERIES

摘要

A micro-hybrid battery system (12) includes a lithium ion battery module (28) configured to be coupled to an electrical load. The lithium ion battery module (28) includes a housing. The lithium ion battery module (28) also includes a first lithium ion battery cell (44a) disposed in the housing and having a first active material chemistry including a first cathode active material and a first anode active material. The lithium ion battery module (28) also includes a second lithium ion battery cell (44b) electrically connected to the first lithium ion battery cell (44a) and disposed in the housing. The second lithium ion battery cell (44b) has a second active material chemistry including a second cathode active material and a second anode active material. The first and second active material chemistries are different such that the first and second lithium ion battery cells (44a, 44b) have different open circuit voltages.
