With the widespread adoption of smart home and IoT technologies, demand for intelligent control in low-light environments is growing. Low-light remote controls, with their battery-free, low-power, and environmentally friendly features, have become a new industry trend. However, the selection of their core energy storage components has always been a focus of the industry chain: Why abandon traditional batteries? How should supercapacitors be adapted? Yongming Capacitor has launched a supercapacitor selection solution tailored to low-light remote control applications, providing detailed answers to 15 core technical questions. This provides the industry with a clear technical reference and promotes the industrialization of low-light remote controls.

## Q: Why choose supercapacitors over traditional batteries for low-light remote controls?

A: The core operating characteristics of low-light remote controls are "extremely low power consumption and intermittent operation." The technological advantages of supercapacitors perfectly meet this requirement while also addressing the application pain points of traditional batteries. First, supercapacitors offer a cycle life of over 100,000 cycles, far exceeding the hundreds of cycles limit of traditional batteries, ensuring long-term use. Second, they offer rapid charge and discharge capabilities, adapting to intermittent energy harvesting in low-light environments. Third, they operate in temperatures ranging from -20°C to +70°C, ensuring stable low-temperature performance. Fourth, they require no regular maintenance, avoiding the high self-discharge rates, low-temperature charging failures, and short lifespans of traditional batteries. This truly meets the environmental and long-life design goals of low-light remote controls.

## Q: What are the core advantages of Yongming lithium-ion supercapacitors over double-layer supercapacitors?

A: Yongming lithium-ion supercapacitors' core competitiveness lies in "higher energy density and greater capacity per unit volume." Due to its limited design, the low-light remote control has an extremely compact internal space. This Yongming capacitor can store more energy within this limited space – this offers two immediate benefits: first, it supports more complex functional expansion, such as voice control and touch feedback; second, it extends the device's standby time, reduces reliance on low-light energy harvesting, and effectively improves the user experience.

## Q: Does the low-light remote control's ultra-low quiescent power consumption (100nA) impose any special requirements on the supercapacitor?

A: The core requirement is that the supercapacitor must have an extremely low self-discharge rate. The low-light remote control's quiescent power consumption is only 100nA. If the supercapacitor's self-discharge current exceeds this value, the collected low-light energy will be completely consumed by the capacitor itself, causing the device to fail to start or operate properly. Yongming supercapacitors achieve an ultra-low self-discharge rate of
