The difference between alkaline batteries and rechargeable batteries:
1. The materials used are different. Alkaline batteries are also called alkaline dry cells, alkaline zinc-manganese batteries and alkaline manganese batteries. They are the highest performing variety of the zinc-manganese battery series. Suitable for large discharge capacity and long-term use. Rechargeable batteries vary in materials and processes, and the most common include lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-metal hydride batteries, and lithium-ion batteries. The advantage is that they have a long lifespan. They can be fully charged and discharged more than 200 times. Some rechargeable batteries have a higher charge capacity than most disposable batteries. When ordinary nickel-cadmium and nickel-hydrogen batteries are usedilized, the unique memory effect causes inconvenience in use and often causes premature failure.
2. Alkaline batteries are disposable batteries and are disposable. The internal resistance of the battery is low, so the current it generates is higher than that of ordinary carbon batteries. This type of battery does not contain mercury, so it can do this. be used at any time. Household waste disposal, no need to recycle deliberately. Because once their power is exhausted, they can no longer be recharged and can only be thrown away. Common disposable batteries include alkaline manganese batteries, zinc-manganese batteries, lithium batteries, silver-zinc batteries, zinc-air batteries, zinc-mercury batteries, and magnesium-manganese batteries.3. Regular batteries are single-use, while rechargeable batteries can be charged with a charger and used repeatedly. The tensionThe nominal voltage of ordinary single batteries No. 1, 2, 3, 5 and 7 is 1.5 V, while the nominal voltage of rechargeable nickel metal hydride and nickel-cadmium batteries is 1.2 V, the The rated voltage of lithium-ion rechargeable batteries is 3.7 V. , and the rated voltage of lead-acid batteries is 12 V.
Rechargeable batteries have memory. Rechargeable nickel-cadmium batteries have a memory effect and have a small capacity; nickel-hydrogen rechargeable batteries have a small memory effect and have a large capacity; rechargeable lithium-ion batteries have no memory effect and are thin and have a large capacity. According to different electrode materials, the electromotive force is 3.6V and 3.7V. The performance of lithium batteries is the best among all types of existing batteries, with small size, light weight and large ability. It is widely used in productselectronics such as digital cameras, laptops and mobile phones. The electromotive force of lead-acid rechargeable batteries is about 12V. Lead-acid batteries can be charged and used repeatedly. The electrolyte is a sulfuric acid solution and the internal resistance is very low. Rechargeable iron-lithium batteries have more power, are safer and lighter. They are the main development direction of electric vehicles in the future. Generally, rechargeable batteries of the same type have larger capacities, larger volumes and heavier weights.
What is the difference between Energizer AA alkaline batteries and AA lithium batteries? Urgent question
AA alkaline batteries are easier to use and can be purchased anywhere. It is more troublesome when the lithium battery is discharged. You must find an al220 V power supply or a car power supply to charge it.
Type AA alkaline batteries have low power and will run out after taking a few photos. Lithium-ion batteries last longer than alkaline batteries.
Type AA alkaline batteries. are cheaper, usually only cost around 2 yuan. Original lithium batteries generally cost more than 100, and branded batteries also cost tens.
1. Strictly speaking, there is no AA lithium battery. There are only two types of AA rechargeable batteries, AA nickel-cadmium batteries and nickel-metal hydride batteries. The nominal voltage is 1.2 V
2. Alkaline batteries are high-capacity batteries and their discharge time is significantly longer than ordinary manganese-zinc batteries. But it cannot be charged. Its nominal voltage is 1.5 V.
3. AA lithium battery may refer to lithium iron batteryphosphate. This is a new type of lithium battery with a voltage of 3V. Therefore, one lithium iron phosphate battery can replace two alkaline batteries. At present, lithium iron phosphate batteries with the same size as AA batteries have appeared on the market. This battery can replace two standard alkaline batteries by adding a dummy AA battery connected in series.
4. Lithium iron phosphate batteries are rechargeable batteries. Since their voltage is different from traditional 3.7V lithium batteries, a special charger is required. Additionally, as with regular lithium batteries, a protection circuit is usually required to prevent overcharging and overdischarging.
