Embodiment Construction

[0043] refer to figure 1 , a battery 1 is a power generation and storage device comprising a battery housing 2 enclosing a stacked arrangement of electrochemical cells 3 . The battery housing 2 is configured such that air, moisture and / or other contaminants are prevented from entering the interior space containing the battery cells 3 . For example, in some embodiments, battery housing 2 is formed from a flexible laminate comprising a metal foil sandwiched between polymer layers and is provided in a sealed pouch.

[0044] The battery cell 3 may be a lithium-ion secondary battery cell, but is not limited to a lithium-ion battery cell chemistry. The cells 3 are free of cell housings, have a generally planar low-profile shape, and are stacked along a stacking axis 5 such that each cell 3 a forms a direct series connection with an adjacent cell 3 b of the cell stack 4 . Each battery cell 3 comprises: a bipolar plate 12 having active material layers 30, 40 disposed on its opposing...

Abstract

A battery includes a stacked arrangement of electrochemical cells. Each electrochemical cell is free of a cell housing and includes a bipolar plate having a substrate, a first active material layer formed on a first surface of the substrate, and a second active material layer formed on a second surface of the substrate. Each cell includes a solid electrolyte layer that encapsulates at least one ofthe active material layers, and an edge insulating device that is disposed between the peripheral edges of the substrates of each pair of adjacent cells. A support frame surrounds the cell stack andis configured to receive and support the outer peripheral edge of the edge insulating device of each cell.

Description

Background technique [0001] Batteries provide power for a variety of technologies ranging from portable electronic devices to renewable energy systems and environmentally friendly vehicles. For example, a hybrid electric vehicle (HEV) uses a battery and an electric motor in conjunction with a combustion engine to improve fuel efficiency. An electric vehicle (EV) is powered entirely by an electric motor, which in turn is powered by one or more batteries. A battery may comprise several electrochemical cells arranged in a two-dimensional or three-dimensional array and electrically connected in series or parallel. In a series connection, the positive and negative terminals of each of two or more battery cells are electrically connected to each other, and the voltages of these battery cells are summed to give a greater voltage to the battery with the battery cells. For example, if n battery cells are electrically connected in series, the battery voltage is the voltage of a single...
