The lithium-ion-ion battery protection device includes an abnormality detection circuit, a light coupling circuit, a balancing circuit, and a recognition circuit. The abnormality detection circuit is to detect the voltage of the lithium-ion-ion battery and output a detection signal. The battery continues to charge/discharge if the signal is normal, and terminate to charge/discharge if the signal is abnormal. Then, the balancing circuit determines whether the detection signal is an overcharged signal, and if yes, the rechargeable battery is discharged accordingly.

Abstract: A low resistance lithium battery set includes a chassis, and lithium batteries. A collector board is disposed in the chassis, which includes many insertion holes for connecting with the electrodes of lithium batteries. The electrodes of the batteries are penetrated through the insertion holes and then folded to connect with each other. The power output of the lithium batteries is then delivered through the contact points of the collector board. The output of the battery set is thus adjustable by changing the connection of battery electrodes. Therefore, the battery set can be used in a variety of electronic devices.

Abstract: An electrolyte injection and degas method of electric energy storage device comprises the following steps. A pipeline connected with the exterior is installed in an electric energy storage device. Next, gas in the battery core of the electric energy storage device is extracted via the pipeline to form a vacuum negative pressure state.

Subsequently, gas generated when the battery core is charged for activation is extracted via the pipeline. A clamp layer for covering the pipeline of the electric energy storage device is then heat sealed. Finally, the pipeline is extruded by hot melt during heat sealing. A degas bag can be saved, and the size of the electric energy storage device can be decreased to lower the cost.
