Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] see figure 1 , the embodiment of the present invention provides a lithium-ion power battery, including a casing, the casing is provided with a positive electrode 11, a first separator 13, a negative electrode 15, and a second separator 17, and t...

Abstract

The invention provides a lithium ion power battery and automobile using the same; the battery sequentially comprises an anode, a first separation membrane, a cathode, and a second separation membrane; the battery contains electrolyte; and the electrolyte contains anti-flaming substances. Due to the anti-flaming substances contained in the electrolyte, the anti-flaming performance of the battery is achieved by the addition of the anti-flaming substances, and these substances do not affect the normal reaction of between the anode and the cathode of the lithium ion power battery, do not affect the performance of the battery when the lithium ion power battery is normally recharged or discharged; when the lithium ion power battery is abused or in abnormality, the anti-flaming substances take effect of anti-flaming and prevent the lithium ion power battery from keeping discharging. Therefore, the passivation layer SEI membrane is prevented from being damaged; the temperature of the battery is prevented from continuously rising; the passivation layer SEI membrane is prevented from decomposing to generate hydrogen free-radical and hydroxyl radical, thus the lithium ion power battery cannot reach the temperature required for generating alkane hydrogen gas, thereby radically preventing the battery from burning or exploding.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a lithium-ion power battery and an automobile using the same. Background technique [0002] Lithium-ion battery is a new type of high-energy battery successfully developed in recent years. The positive and negative electrode materials of lithium-ion batteries are chimeras that can intercalate lithium ions. Its research began in the 1980s. Due to its excellent performance, lithium-ion batteries have been widely received since Armand proposed its concept in 1980. attention and has developed rapidly. Due to the continuous improvement and improvement of lithium-ion battery performance, its application range is also expanding, and now it has also been widely promoted and applied in the field of new energy vehicles. [0003] The lithium-ion power battery structure generally includes a positive electrode, a negative electrode, an electrolyte, a diaphragm, a battery case, and the like...
