Abstract: A fast charging lithium-ion battery includes a positive electrode plate, a negative electrode plate, a separator, and an electrolyte. The positive electrode plate includes a positive current collector and a positive active material layers. The negative electrode plate includes a negative current collector and negative active material layers. The negative active material layers include titanium niobium oxide, lithium titanate, or a combination thereof. The separator is disposed between the positive electrode plate and the negative electrode plate. The electrolyte contacts the positive electrode plate and the negative electrode plate. The negative active material layers have an effective area corresponding to the positive electrode plate. The negative active material layers have a thickness on one surface of the negative current collector. A ratio of the effective area to the thickness is greater than 2×105 mm.

Abstract: An actuating structure of battery safety valve includes an end plate, a safety valve, a positive-terminal conductive plate, a negative-terminal conductive plate, a ventilate plate and an actuating plate. A positive terminal and a negative terminal penetrate through the end plate and the safety valve. The positive-terminal and the negative-terminal conductive plates are disposed on the end plate and extended from the positive terminal and the negative terminal to the safety valve, respectively. The ventilate plate is disposed on the end plate and corresponding to the safety valve. The actuating plate is disposed between the ventilate plate and the safety valve, and restricted under a normal condition by the safety valve. When an internal pressure of the battery exceeds a breaking pressure of the safety valve, the actuating plate is released, so that an electric connection path is formed between the positive and the negative terminals.
