According to Hyundai Motor’s official statement, Hyundai, Kia and Factorial Energy are cooperating to test Factorial’s new solid-state battery technology. Thanks to the blessing of new technologies, solid-state batteries can extend vehicle mileage by 20% to 50%.According to the joint development agreement, Hyundai, Kia, and Factorial Energy will integrate Factorial technology at the battery, module, and system levels, carry out vehicle-level integration, and jointly develop and manufacture Factorial batteries.
Factorial’s breakthrough technology is based on FEST (Factor Electrolyte System Technology), which uses a proprietary solid electrolyte material. This solid-state battery can maintain safe and reliable performance under high voltage and high energy density conditions. The first round of tests on a 40Ah battery at 25°C showed that after 675 cycles, the battery capacity retention rate was 97.3%. FEST is safer than traditional lithium-ion technology, can extend the mileage by 20% to 50%, and is directly compatible.
