Learn MoreCurrently, the main drivers for developing Li-ion batteries for efficient energy applications include energy density, cost, calendar life, and safety. The high energy/capacity anodes and cathodes needed for these applications are hindered by challenges like: (1) aging ...
Learn MoreYou can control the battery''s current and voltage in two principals ways: carry out overcurrent and overvoltage protection during charging and avoid undervoltage as you discharge the battery. The main point : Every battery type has recommended current and voltage limits for both charging and discharging.
Learn MoreLow voltage does not mean low hazard! Even contact with extra low voltage below the limit value of 50 V AC or 120 V DC can cause accidents. In some critical work areas, it may be necessary to limit the voltage to lower than 24 V AC or 60 V DC, for example, in conductive or wet locations with restricted movement.
