This paper describes an innovative approach to develop high density and ultra-thin solid aluminum capacitors for high voltage automotive applications that sustain high temperatures. Form factors of less than 100 μm thickness are achieved with densities of 16.85, 1.91, 1.13, and 0.705 μF/cm2, for capacitors anodized to 10, 100, 150, and 200 V respectively. The capacitors exhibit good frequency stability up to 100 kHz and demonstrate the first aluminum capacitors to come in such a thin format. These capacitors can be used in new era automotive electronics where high density and high voltage stability is critical.
