Lighter, with more power than traditional chemistries, the new high-rate lithium ion cell, CGR26650A, is suited for portable power tools, medical equipment, backup power, and uninterruptible power supplies. The cell’s nickel-manganese–based cathode material reportedly delivers higher discharge rates and better temperature stability than comparative cells, while the firm’s exclusive heat resistance layer technology provides safer operation.
