How do Ni-MH and Li-ion batteries compare in performance?
Ni-MH and Li-ion batteries differ significantly in performance: Li-ion excels in energy density (150-250 Wh/kg vs. 60-120 Wh/kg), self-discharge rate (2-5% vs. 20-35% monthly), and cycle life (1,000+ vs. 300-500 cycles). Ni-MH offers lower costs,… How do Ni-MH and Li-ion batteries compare in performance?
