Safe Li-Ion Technology for Micro and Mild Hybrid application based on CEA Bipolar LiFePO4/Li4Ti5O12 technology
Abstract
The patented bipolar battery developed in CEA for the Hybrid Electric Vehicle (HEV) is based upon the use of Li4Ti5O12 as anode material (allowing the use of a common bipolar aluminium current collector, and high power application) and LiFePO4 (cycle life, safety, low cost). The main target has been first to achieve a sealed system with no electrolyte leakage, and then to demonstrate the advantage of the Li4Ti5O12 / LiFePO4 couple (1.9V) for high power Li-ion bipolar battery. To increase the battery cycle life, a new design has been elaborated and has allowed to develop standard energy battery of 15Wh (24V, 0.65 Ah).
In this paper, first results on 15Wh cells, using the Li4Ti5O12 / LiFePO4 couple and a new bipolar battery design, will be presented according HEV profiles.
