NOVELTY - The lithium ion battery comprises a shell (1), an electric core (3) disposed in the shell with a space (4), and a non-aqueous electrolyte housed in the shell. The space is filled with a non-aqueous electrolyte resistance filler made of a particulate material. The particulate material comprises hollow spheroidal particles having an average inner diameter of 1-10 mm and an average external diameter of 2-15 mm. The electric core is formed by superposing or winding a positive electrode plate, a negative electrode plate, and a separator between the positive and negative electrode plates.    USE - The lithium ion battery is useful in electronic products such as notebooks and mobile telephones.    ADVANTAGE - The lithium ion battery has high voltage, high capacity, less power consumption, no memory effect, no pollution, small volume, high specific energy, low internal resistance, low self-discharge rate, multiple cycle times, good safety performance and various volume and appearance.    DETAILED DESCRIPTION - The lithium ion battery comprises a shell (1), an electric core (3) disposed in the shell with a space, and a non-aqueous electrolyte housed in the shell. The space is filled with a non-aqueous electrolyte resistance filler made of a particulate material. The particulate material comprises hollow spheroidal particles having an average inner diameter of 1-10 mm and an average external diameter of 2-15 mm. The electric core is formed by superposing or winding a positive electrode plate, a negative electrode plate, and a separator between the positive and negative electrode plates. The shell has a ratio of length:width:height of 50-800:30-500:5-500. The electric core has a ratio of length:width:height of 45-795:25-495:5-100.
