This product was achieved by finding a weak acid among many acids that reduces the load on supercapacitor components and improves high temperature reliability. By combining this new aqueous electrolyte, phosphoric acid, with our conventional core technology, we have developed the industry\'s first AEC-Q200 Grade 2 \105 °C guaranteed\" supercapacitor. The life of products to which aqueous phosphoric acid solution is applied is more than three times longer than that of conventional products using aqueous sulfuric acid solution."
