Abstract: Embodiments of the present invention provide a load sharing method and apparatus, and a board. The method includes: receiving, by a built-in forwarding unit, to-be-transmitted data; obtaining, by a management control unit, current load ratios of forwarding units; and if it is determined that a current load ratio of any forwarding unit of the forwarding units is less than a preset load ratio threshold, determining that the forwarding unit is a unit for forwarding the to-be-transmitted data, where the built-in forwarding unit and the management control unit are located in a same board, and the forwarding units include the built-in forwarding unit and another forwarding unit outside the board. The present invention can solve a problem of low data transmission reliability in an existing load sharing method.

Abstract: A negative electrode plate of a lithium-ion battery, a lithium-ion battery, and an electronic device are provided. The negative electrode plate of the lithium-ion battery includes a negative electrode current collector and an additional layer. The additional layer is disposed on a surface of the negative electrode current collector. The additional layer includes a negative electrode active substance, a protective substance, and a bonding agent. The negative electrode active substance includes at least one of a carbon material, an alloyed material, and a silicon material, the protective substance includes a nanometal oxide and a conductive agent, and the protective substance further includes lithium titanate or carbon-coated lithium titanate. When the lithium-ion battery is damaged, the protective substance can reduce a risk of thermal runaway caused by a short circuit between a positive electrode current collector of a positive electrode plate and the negative electrode active substance.

Abstract: A battery packaging film includes a metal layer, a first bonding enhancement layer, a first bonding layer, a second bonding layer, a first protective layer, and a second protective layer. The first bonding enhancement layer is located on a first surface of the metal layer. The first bonding layer is located on a surface of the first bonding enhancement layer away from the metal layer. Because the first bonding enhancement layer is added to an upper surface of the metal layer, roughness of the upper surface of the metal layer is increased to enhance strength of bonding between the first protective layer and the metal layer and minimize occurrence of unintended separation of the first protective layer from the metal layer, thereby enhancing safety of the battery packaging.

Abstract: A battery includes an unpackaged cell and a packaging film, where an edge of the unpackaged cell includes at least one first open space. The first open space runs through a thickness direction of the unpackaged cell. No unpackaged cell exists in the first open space. The packaging film encloses an enclosed space that accommodates the unpackaged cell. The packaging film forms a first sealing part in the first open space. The first sealing part does not cover the unpackaged cell. The first sealing part encloses a second open space with a packaging film on a sidewall of the first open space. The first open space partly overlaps the second open space.

Abstract: A battery packaging material has both a high-temperature-resistant fireproof characteristic and a fire-retardant fireproof characteristic. The battery packaging material is successively disposed with a protective layer, a metal layer, and an encapsulating layer from outside to inside, where a first high-temperature-resistant layer is disposed between the metal layer and the protective layer; a second high-temperature-resistant layer is disposed between the metal layer and the encapsulating layer; and a fire-retardant layer is disposed above the protective layer, between the protective layer and the metal layer, between the metal layer and the encapsulating layer, or below the encapsulating layer.
