C-rate (or Charge/Discharge Rate) is a measure of the speed at which a battery is charged or discharged relative to its nominal capacity. It is expressed as a multiple of the battery’s rated capacity per hour, and is a critical parameter in battery performance, safety, and longevity.
Impact of C-rate
Higher C-rates increase power availability but may reduce battery cycle life and efficiency due to internal heat and side reactions.
Lower C-rates are gentler on the battery, ideal for long-duration energy storage or slow-charging applications
