A method and apparatus is disclosed for charging lead-acid batteries which comprises periodic voltage sweeps to determine the charging voltage that should be used for the battery and then adjusting the charging voltage in accordance with that voltage sweep information so as to ensure that a highly efficient charging process is achieved which avoids undue gassing and inherently compensates for factors such as the temperature, type and service life history of the battery and resistance due to the interactive nature of the technique and apparatus. One suitable technique for analysis and adjustment of the voltage sweep data involves analyzing the slope of the current versus the voltage sweep curve so as to determine certain slope values or changes in values.

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. Electrolyte is then injected into the battery core via the pipeline. Next, the battery core is kept at the vacuum negative pressure state and charged for activation. 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.

A power disconnection apparatus includes a soft-shell Li ion battery and a power disconnection device. The soft-shell Li ion battery includes anode pin and a cathode pin and a soft shell enclosing the soft-shell Li ion battery. The power disconnection device includes a panel attaching to the surface of the shell of the soft-shell Li ion battery and a separation unit arranged at topside of the panel and corresponding to one of the anode pin and the cathode pin. The shell has expansion when the soft-shell Li ion battery is over-charged and the panel is move away from the soft-shell Li ion battery. Therefore, the separation unit disconnects power to the anode pin or the cathode pin.

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.

A lithium-ion battery protection method and device controls an externally connected circuit to charge/discharge a rechargeable battery so as to prevent the rechargeable battery from over charging/discharging. 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. Meanwhile, the light coupling circuit adjusts an impedance of the light coupling circuit based on the detection signal so as to break the connection between the rechargeable battery and the externally connected circuit, and the recognition circuit outputs signal identifying location of the battery.

A manufacturing method of secondary battery and the device thereof are proposed. In this method, conducting material is trimmed into positive and negative electrode plates. Positive and negative active materials are coated on the positive and negative electrode plates, respectively. The positive and negative electrode plates are alternately arranged on a strip-shaped separator in an appropriate order. The positive and negative electrode plates on the separator are folded and then stacked according to their arrangement order so that each of the positive and negative electrode plates can be separated by the separator, and opposed faces between the positive and negative electrode plates have the active material coated thereon. The manufacturing process can thus be simplified, and the size and specification can be quickly changed to accomplish convenience in expansion. Moreover, the yield can be enhanced to accomplish the optimum economic benefit of production.
