Abstract
Description
technical field
[0001] The invention belongs to the technical field of lithium-ion battery preparation, and relates to a fast-charging and fast-discharging lithium-ion battery and a manufacturing method thereof. Background technique
[0002] Lithium-ion secondary battery has now become the mainstream chemical power source, and is widely used in most mobile terminal equipment and new energy vehicles. Long life and other advantages. In recent years, with the rapid development of electric tools, unmanned aerial vehicles, aircraft models, and new energy vehicles, especially with the batch application of lithium-ion batteries in HEV hybrid vehicles and 12V / 48V vehicle start-stop systems, lithium-ion secondary The charging and discharging power requirements of the battery are getting higher and higher, and generally need to meet the 30-40C rate charging and discharging requirements, but it is difficult for commercial lithium-ion batteries to meet such high-power charging and disc...
