摘要： The invention provides a lithium secondary battery including an ionic provider added to the positive electrode and/or a lithium receiver added to the negative electrode. The ionic provider and/or the ionic provider does not involve in the electrochemical reaction of the lithium secondary battery during charging and discharging. The ionic provider can absorb thermal energy caused by the rising temperature of the lithium secondary battery to release the reactive cation. The reactive cation will insert the location with lithium-ion extraction of the positive electrode to make the lattice structure of the positive active material be stable. Therefore, the release of atomic oxygen is avoided. The lithium receiver receives the diffused lithium from the negative electrode to reduce the lithium concentration of the negative electrode. Therefore, it will present a stable state with lower energy to effectively suppress the thermal runaway.

摘要： This invention provides a thermal runaway suppression element for lithium batteries and the related applications. The thermal runaway suppression element includes a composite salt layer provided by a eutectic mixture containing at least two single inorganic salts. The composite salt layer has a melting point between 90 to 150° C. At least one of the single inorganic salts comprises a cation, which is an amphoteric metal ion or an alkali metal ion. The thermal runaway suppression element is disposed inside or outside the lithium battery. When the temperature of the lithium battery reaches to 90 to 150° C., the composite slat layer will be molten and reacts with the electrochemical reaction system to passivate the active materials and decrease ionic and electronic conductivity. Therefore, the thermal runaway event and its derived problem are efficiently solved.

摘要： The invention provides a soft pack battery module and its electricity supply thereof. The battery units, which are independent and complete modules, are utilized to be contacted to each other to form the battery cell with the serial connection, the parallel connection or both. There only have charges transferred rather than electrochemical reactions occurred between the battery units. Also, the metallized plastic film package is utilized to pack the battery cell. The inner electrically-conductive area of the metallized plastic film package is directly contacted to the electric power outputs of the battery cell to form electrical connections. Therefore, the problems caused by the need for additional wires can be avoided and the surface area the current path of the battery cell can be maximized.

摘要： The invention provides an electrode assembly and its battery device thereof, which is composed of a first belt current collector and a second belt current collector, which a plurality of electrochemical systems are disposed therebetween. Also, the glue frame is utilized to completely enclose thereof. Therefore, each electrochemical system is an independent module and there only have charges transferred occurring rather than electrochemical reactions therebetween. The glue frame located between the electrochemical systems and the first belt current collector and the second belt current collector adhered by the glue frame can be folded to form a bending portion. By the bending portion, the electrochemical system would be folded to overlap the adjacent electrochemical system to achieve a z-axis stacking. It is easy to mass produce, and it can also reduce the amount of the tabs configured in series or parallel. Therefore, the energy density loss of the space configuration can be reduced.

摘要： The invention provides a thermal runaway suppressant of lithium batteries and the related applications. The thermal runaway suppressant includes a passivation composition supplier, for releasing a metal ion (A), selected from a non-lithium alkali metal ion, an alkaline earth metal ion or a combination thereof, and an amphoteric metal ion (B), a polar solution supplier and an isolating mechanism, which is capable of separating the passivation composition supplier and the polar solution supplier within a predetermined temperature. When the isolating mechanism is failed and the polar solution supplier releases a polar solution to carry the metal ion (A) and the amphoteric metal ion (B) into the lithium battery and react with the positive active material and the negative active material to a state with lower energy. The voltage of the whole battery is decreased and the electrochemical reaction pathway is blocked to prevent the thermal runaway from occurring.

摘要： The invention discloses a composite electrode materials. The composite electrode materials of this invention includes at least one active material. The active material is coated an artificial passive film on its surface to effectively block the contact of the electrolyte and the active material to prevent unnecessary consumption of Li-ions. Also, there have a middle layer and an outer layer outside of the artificial passive film. Both of the middle layer and the outer layer are composed of the gel/liquid electrolyte and the solid electrolyte, but with different concentration ratios. Therefore, the better ion-conduction is achieved with reduced charge-transfer resistance and reduced amount of organic solvent.
