There is no complete substitution relationship between primary battery and secondary battery, and primary battery has an advantage in the use of low-power electrical appliances. Chemical batteries can be divided into primary batteries and secondary batteries according to the nature of use. Primary batteries, also known as "primary batteries", lose their effectiveness after the active substances in the batteries are consumed, such as alkaline zinc-manganese batteries, carbon zinc-manganese batteries and primary lithium battery. Secondary batteries, also known as "batteries", can be used repeatedly by charging after the power is exhausted. There are commonly nickel-hydrogen batteries, lithium-ion batteries, lead-acid batteries, nickel-cadmium batteries and so on. Although the application fields of primary batteries and secondary batteries overlap to some extent, there are still clear boundaries in the main use scenarios, and there is no complete substitution relationship. In recent years, the trend of household consumer appliances has gradually developed towards small and medium power consumption, and primary batteries still dominate in these scenarios.Zhou Du research focus: research on zinc-manganese battery industryZhou Du research focus: research on zinc-manganese battery industry
