Abstract
A battery group that cycles lithium ions includes at least one first monopolar electrode having a first polarity and having a first tab and at least one second monopolar electrode having a second polarity opposite to the first polarity and a second tab. The first tab and the second tab are in direct electrical communication with an external circuit. At least one bipolar electrode is disposed between and electrically insulated from the first monopolar electrode and the second monopolar electrode, wherein a first side of the bipolar electrode has the first polarity and a second side of the bipolar electrode has the second polarity. The battery thus comprises at least one first unit cell connected in parallel and at least one second unit cell connected in series.
Description
[0001] introduction [0002] This section provides background information related to the present disclosure which is not necessarily prior art. technical field [0003] The present disclosure relates to a hybrid lithium-ion electrochemical battery cell having a combined output of relatively high voltage and high current and facile assembly and stacking of electrodes. The lithium-ion battery pack may include at least one first unipolar electrode with a first polarity and at least one second unipolar electrode with a second polarity, which are respectively in electrical communication with an external circuit. The lithium ion battery pack also includes at least one bipolar electrode disposed between and electrically insulated from the first unipolar electrode and the second unipolar electrode to provide a battery having at least one unit cell having a parallel electrical connection and at least one having A lithium-ion battery pack of cells electrically connected in series.
