摘要： The invention discloses an active material ball electrode layer structure, which mainly includes the active material balls made of the active material particles, a first mixed electrolyte located inside the active material balls, and a second mixed electrolyte located outside the active material balls. The first mixed electrolyte is mainly made of the deformable electrolyte. The second mixed electrolyte is mainly made of the electrolyte with relatively lesser deformation than the deformable electrolyte of the first mixed electrolyte. The invention utilizes the first mixed electrolyte to effectively active material ball reduce the derived problems of the volume change of the active materials. Moreover, the different configuration of the first mixed electrolyte and the second mixed electrolyte inside and outside the active material balls is utilized to reduce the charge transfer resistance. Also, the expansion resistance is provided for the active material balls.

摘要： The invention provides a method for suppressing thermal runaway of lithium batteries, which is included a step of providing a lithium battery capable of performing charging and discharging, which includes an electrochemical reaction system. When the temperature of the lithium battery reaches to a predetermined temperature, a metal ion (A) and an amphoteric metal ion (B) are applied to the positive active material layer and the negative active material layer of the lithium battery to passivate the positive active material layer and the negative active material layer. The metal ion (A) is selected from a non-lithium alkali metal ion, an alkaline earth metal ion or a combination thereof to prevent the thermal runaway from occurring.

摘要： The invention discloses an active material ball composite layer. The active material ball composite layer includes a plurality of active material balls and an outer binder. The active material ball include a plurality of active material particles and a first conductive material. An inner binder is used to adhere the active material particles and the first conductive material to form the active material balls. Then, the outer binder is used to adhere the active material balls to form the composite layer. The elasticity of the inner binder is smaller than the elasticity of the outer binder. Therefore, the scale of expansion of the active material particles is efficiently controlled during charging and discharging. The unrecoverable voids would be reduced or avoided.

摘要： The present disclosure relates to a horizontal composite electricity supply structure, which comprises a first insulation layer, a second insulation layer, two electrically conductive layers, and a plurality of electrochemical system element groups. The two electrically conductive layers are disposed on the first and second insulation layers, respectively. The electrochemical system element groups are disposed between the first insulation layer and the second insulation layer, and connected in series and/or in parallel via the electrically conductive layers. The electrochemical system element group is formed by several serially connected electrochemical system elements. Each electrochemical system element includes a package layer on the sidewall, so that their electrolyte systems do not circulate with one another. Thereby, the high voltage produced by connection will not influence any single electrochemical system element nor decompose their respective electrolyte systems. Hence, serial and/or parallel connections are made concurrently in the horizontal composite electricity supply structure.

摘要： A horizontal composite electricity supply element group comprises a first insulation layer, a second insulation layer, a first patterned conductive layer, a second patterned conductive layer, and a plurality of electricity supply element groups. The first patterned conductive layer is disposed on the first insulation layer. The second patterned conductive layer is disposed on the second insulation layer. The plurality of electricity supply element groups are disposed between the first insulation layer and the second insulation layer, and connected in series and/or in parallel via the first patterned conductive layer and the second patterned conductive layer. The electricity supply element group is formed by several serially connected independent electricity supply elements whose electrolyte systems do not circulate with one another. Thereby, the high voltage produced by connection will not influence any single electricity supply element nor decompose their respective electrolyte systems.

摘要： An air-floating thin film bonding apparatus and its air-floating roller is provided. The apparatus is composed of an air-floating rollers, which can blow out airflow at a specific angle to be applied to the base film with three-dimensional obstacles. The positive pressure provided by the airflow can be utilized to fill the gap space caused by the three-dimensional obstacles. Therefore, the base film can bond to the bonding film tightly to overcome the wrinkles and defects caused by the three-dimensional obstacle and the problem of unflatness of the film-bonding can be solved.
