battery formation time Explanation: Battery formation is the process of performing the initial charge/discharge operation on the battery cell. During this stage, special electrochemical solid electrolyte interphase (SEI) will be formed at the electrode, mainly on an anode. This layer is sensitive to many different factors and has major impacts on battery performance during its life time. Battery formation can take many days depending on the battery chemistry. Using a 0.1 C (C is the cell capacity) current during formation is very typical, taking up to 20 hours for a full charge and discharge cycle, making up 20% to 30% of the total battery cost. Analog Devices offers a comprehensive battery formation control system solution based on a single silicon chip, the AD8452. With precise formation process performance, formation time for each battery cell can be optimized. https://www.analog.com/en/technical-articles/power-efficient... High charging currents are also used which contribute to a shorter battery formation time. https://www.esi-africa.com/industry-sectors/energy-efficienc... In cases studied by Rigby and McDonagh, this can amount to a 20% increase in a battery’s formation time. Even a few hours per day per circuit, with 7-days-a-week working times, can lead to high percentage losses in total factory output. https://www.bestmag.co.uk/content/peak-battery-performance-n... |

batteries (plates) forming time/period Explanation: Формовка батарей (точнее, пластин аккумуляторных батарей) - это несколько процессов их предварительного заряда-разряда для активизации поверхности пластин и выхода аккумулятора на оптимальный режим работы Формовка аккумуляторных батарей http://www.4akb.ru/stati/formovka-akkumulyatornykh-batarey/ Формовка нужна для батарей любого типа — даже литий-ионных и литий-полимерных. Признаком успешной формовки аккумулятора является замедление роста его времени разряда после его полного заряда. Формовка пластин аккумулятора является важной стадией в процессе его изготовления. В процессе формовки происходят реакции разрядки и перезарядки батареи за счет электрохимического превращения активного вещества. Поскольку, пластины аккумулятора содержат эти вещества, происходит процесс преобразования химической энергии в электрическую и наоборот. Для того, чтобы сделать пластины активными, их подвергают формовке, превращающей неактивные оксиды и сульфаты свинца в металлические, которые являются активными. US3871919A - Battery plate forming apparatus patents.google.com › patent A battery plate forming tank having a removable cover with a filter vent therein to permit the gases generated in the forming process to escape but to condense and retain acid vapors in the tank.
