What are the types of commonly used batteries?

Battery Type

Batteries play an important role in our daily life. Lighting, mobile phones, cameras, watches, microphones, laptops, electric cars, new energy vehicles, electric toys, remote controls. All these devices require batteries. There are many types of batteries, including lithium batteries, solar cells, fuel cells, air batteries, lead-acid batteries, and carbon batteries.

Here, let me introduce you more about batteries. First, it is about battery types.

Common battery types

1 Zinc-carbon battery

Zinc-carbon battery, commonly known as carbon battery, is a commonly used battery in daily life and is also the cheapest type of battery. This battery has low battery capacity and is prone to leakage. It is used in TV remote controls and other products. Primary battery voltage: 1.5V.

2 alkaline batteries

Alkaline battery is the most commonly used battery recently. Its advantage is that it has a long-lasting power, which can be 7 times that of carbon batteries. Its current output is stable. There is also no leakage. It can be used for devices with high power consumption. Original battery voltage: 1.5V

3. Nickel-cadmium battery

Disadvantages of nickel-cadmium batteries: large size, heavy weight, small capacity, self-discharge, memory effect, not environmentally friendly. Advantages: can be recharged more than 500 times, very economical; small internal resistance, large discharge current. Therefore, this product is often used in power tools. Rechargeable battery voltage: 1.2V

4 NiMH batteries

Compared with NiCd batteries, NiMH batteries have a disadvantage that they cannot be used for high current discharge (there are already factories producing high current discharge NiMH batteries). The advantage is that the capacity is more than twice that of NiCd batteries of the same size. With its small memory effect and no pollution, it is called a green battery. Rechargeable battery voltage: 1.2V.

5. Lithium-ion battery

The shell of lithium-ion battery (Li-ion battery) includes steel and aluminum shell. The capacity of aluminum shell is 10% to 15% higher than that of steel shell. Advantages: small size, large capacity, high voltage. Shape: cylindrical, square, deformed. Commonly used mobile phone batteries, PDA batteries, laptop batteries Voltage: 3.7V.

6 Lithium polymer battery

Comparison between Li-polymer Battery and Li-ion Battery: The outer packaging is aluminum-plastic packaging, which is different from the metal shell of Li-ion. Due to the use of soft packaging technology, thinner batteries can be produced. The shape can be changed freely. Advantages: light weight, higher capacity, low resistance, and support for large current discharge. Commonly used in high-end mobile phone batteries, laptop batteries, various power tools and models Battery voltage: 3.7V.
