Abstract: The lithium-ion secondary battery comprises a positive electrode, a negative electrode, a separator, and an electrolyte. The negative electrode has a negative electrode current collector, and a negative electrode mixture layer formed on a surface of the negative electrode current collector. The negative electrode mixture layer includes a carbon-based material and a silicon-based material as a negative electrode active material. The discharge capacity of the negative electrode active material is 400-750 mAh/g. The thickness of the negative electrode current collector is 4-12 μm, and the 1% offset yield strength of the negative electrode current collector is 300-700 MPa. The separator has a base material layer, a filler layer formed on a surface of the base material layer, and a resin layer formed on a surface of the base material layer or the filler layer. The porosity of the resin layer is 30-80%.

Abstract: A ranging device includes transducers, a transmission circuit, a reception circuit, a transfer data generation circuit, and a transfer circuit. The transmission circuit causes the transducers to transmit transmission waves. The reception circuit outputs a received signal obtained by digitizing a reflected wave of the transmission wave with a sampling frequency equal to or more than a frequency of the transmission wave. The generation circuit separates, into a target period and a non-target period, time-series received signals. The target period is a period in which a wave height is equal to or more than a threshold. The non-target period is a period in which a wave height is less than the threshold. The generation circuit performs thinning-out processing on received signals in the non-target period and generates waveform information indicating a waveform received by the transducer. The transfer circuit outputs the waveform information.
