In 1991, a new type of storage battery called the PASL battery, which became the basis for lithium-ion capacitors, was born. The decisive difference from the lithium-ion battery that was also born that year is that the negative electrode is pre-doped for higher voltage. Pre-doping technology has recently gained attention because it can improve the energy density and extend the cycle life when applied to lithium-ion batteries and similar technologies. In this blog, we will introduce what pre-doping technology is, its methods and mechanisms, and why pre-doping was necessary for the PASL battery. For more details, please refer to the related links.
