Technical Field
[0001] The utility model belongs to the technical field of new energy logistics vehicles, and specifically relates to a protective structure of a special blade battery. Background Art
[0002] Blade batteries are lithium-ion batteries made of lithium iron phosphate materials. Their uniqueness lies in the shape and size of the battery and the production process. Any metal body that comes into direct contact with the battery cell must be insulated, so insulation treatment of the battery cell body is necessary. This insulation protection mainly considers the possible contact of the battery cell during storage, during transportation, during assembly, and after grouping. Blade batteries are square batteries shaped like blades. Blade batteries generally use PET blue film, which is insulated by bonding it to the aluminum alloy shell of the battery cell through pressure-sensitive adhesive. The PET blue film has poor puncture resistance. Surface scratches can easily cause puncture and wear of the blue film, causing short circuits or performance degradation. At present, the transportation vehicles of blade batteries are all hard plastic baskets. Generally, there is no protection in the basket or artificial soft fixation is used to protect the blade battery. Without protection, the wear problem of the blue film cannot be solved. The additional protection is not only time-consuming and labor-intensive, but also cannot be reused. The production efficiency is also very low and cannot meet customer requirements.
