Accumulator electrode with internal particle movable and producing process thereof

Abstract

The invention relates to a battery electrode with movable internal particles and a preparation method thereof, and pertains to the technical field of the battery electrode. The battery electrode is characterized in that the battery electrode comprises an electrode frame which is arranged in the battery body, movable electrode particles are piled in the electrode frame, the electrode particles are negative particles or positive particles made of solid electrode material, the electrode frame has net-shaped structure and is connectively provided with an input pipeline and an output pipeline which extend out of the battery body, and the electrode frame is connectively provided with an electrode post head. The battery electrode with movable internal particles and the preparation method thereof break through the traditional model in which the battery electrode is fixed in the battery. The electrode particles of the battery electrode can be input into or output from the battery body, can be charged in the battery body and also can be moved out of the battery body to carry out charging and maintenance. The battery electrode has the advantages that the manufacturing automatization of the battery electrode can be realized; the volume and the weight of the battery are reduced; the use performance of the battery is improved; and fast charge is achieved.

Description

technical field [0001] The invention belongs to the technical field of battery electrodes, in particular to a battery electrode with movable internal particles and a production method thereof. Background technique [0002] The existing storage battery includes a pair of electrodes fixed inside the storage battery: the cathode (positive electrode) and the anode (negative electrode). The discharge and charging process of this storage battery is that oxidation and reduction reactions occur between the pair of electrodes respectively. During the discharge process In the charging process, the anode is oxidized and loses electrons, and the cathode is reduced to gain electrons, and in the charging process, this reaction is reversed. Once the charging process is completed, it enters the next round of discharging and charging process, thereby completing a working cycle of the battery. At present, the production and use of batteries follow the traditional mode in which the electrodes...

Problems solved by technology

[0004] 2. The charging time is too long and remains unchanged

Due to the long and fixed charging time of batteries under the current technology, some batteries with specific requirements for charging time, such as electric vehicles with high requirements for charging time limit, have the defect that they cannot be charged quickly and in a short time. The use of special batteries for electric vehicles is difficult to promote

[0005] 3. The production process of the fixed electrodes inside the existing battery is too complicated

Its production process cannot be automated. For example, the current process of battery electrode installation is still in the manual stage. The electrodes of each battery are installed in the subsequent process. The process is complex and has low production capacity and pollutes the environment.

[0006] 4. The plate of the existing storage battery is heavy and bulky

In order to prolong the service life of the battery electrodes as much as possible, the battery plates are often made as thick as possible. As a result, the battery products in this mode are relatively bulky and bulky

[0007] 5. The service life and efficiency of the electrode cannot be guaranteed

Due to the different production standards of the manufacturers, the battery products produced have different requirements for the use environment. Due to improper use, the work of the battery is not in the working area, causing electrode loss, which will greatly shorten the service life of the battery than the design requirements.

[0008] 6. Existing batteries are difficult to adapt to the marketization of electric vehicles

The use of electric vehicles is inseparable from the necessary condition of charging batteries in a timely and convenient manner. Due to the long charging time of electric vehicle batteries in the prior art, they do not meet the requirements of timely supply of electric energy to make electric vehicles convenient to use. The use and popularization of automobiles cannot be promoted, and the development of the electric vehicle industry is hindered
