It is interesting to see 70mai's stated rationale for using a lithium-ion battery rather than a super-capacitor, although they admit that lithium batteries do not fare well in extreme temperatures. They also state that they are looking into using super-capacitors due to extensive user feedback.
What is the supercapacitor solution? What are the Pros and Cons of the supercapacitor and the lithium battery?
"The application of the super-capacitor is the combined use of button batteries and the super-capacitors. The super-capacitor itself can store very little power. It will shut down immediately after power cut, risking the possibility that critical footages cannot finish recording in extreme conditions.The application of the lithium battery is using lithium batteries as a backup power source. Even when the power is cut off, the dash cam will still be able to finish recording the emergency video. The drawback is that lithium batteries do not discharge well under extremely high or low temperatures. We believe that the priority of the dash cam is capturing footage even in extreme conditions, so we chose the lithium battery solution and equipped it with precise safety protection logic. However, based on extensive user feedback, 70mai will explore the super-capacitor solution in future products."
