Embodiment Construction

[0021] Such as figure 1 , figure 2 shown. The resonant lithium battery device 10 with damping function provided by the present invention is composed of at least one identical battery stack 11 connected in series / parallel. Each battery stack 11 includes a Lithium-ion battery 12 and a Lithium-ion polymer battery 13 . The lithium ion battery 12 and the lithium polymer battery 13 are connected in parallel.

[0022] The lithium-ion battery 12 is a current-type battery, which is good for discharging. The lithium polymer battery 13 is a voltage type battery, which is beneficial for charging. The voltage of the lithium ion battery 12 is the same or nearly the same as the voltage of the lithium polymer battery 13 . Since the lithium ion battery 12 and the lithium polymer battery 13 are connected in parallel, the voltages of the two stored electric energy must be the same. Therefore, the voltage balance between the lithium ion battery 12 and the lithium polymer battery 13 is auto...

Abstract

The present invention discloses a resonant type lithium battery device with a damping function. At least one identical battery stack is connected in series and in parallel so as to form the resonant type lithium battery device; each battery stack includes a lithium-ion battery and a lithium-polymer battery; the lithium-ion battery and the lithium-polymer battery are connected in parallel; the lithium-ion battery is a current type batter, so that discharging can be benefitted; the lithium-polymer battery is a voltage type battery, so that charging can be facilitated; the voltage of the lithium-ion battery is the same as or close to the voltage of the lithium-polymer battery; and the lithium-ion battery and the lithium-polymer battery will generate a resonance damping effect due to a voltage automatic balance relation, and therefore, rapid charging and rapid discharging can be performed, temperature rise can be avoided, and the service life of the lithium battery device can be prolonged.

Description

technical field [0001] The invention relates to a lithium battery device which is composed of a lithium ion battery and a lithium polymer battery connected in parallel. The resonant transition of current and voltage can be generated inside the battery, so that it has a damping function and is beneficial to fast charging and fast discharging. Background technique [0002] Lithium-ion battery (Lithium-ion battery) is the most widely used battery in various consumer electronic products. For example, the rechargeable batteries in various portable electronic products are mostly lithium-ion batteries. Lithium-ion batteries have the characteristics of high energy density, small size, high output power, no memory effect, and low self-discharge rate when not in use. Lithium-ion batteries have a wide operating temperature range and can work normally between 20°C and 60°C. [0003] When charging a lithium-ion battery, it takes a long time to charge due to the capacitive anti-farad for...
