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.
