Energy storage batteries are devices that store electrical energy, converting it into chemical energy through a chemical reaction and storing it. When needed, the reverse reaction converts the chemical energy back into electrical energy for output. The following types of energy storage batteries are commonly found on the market:
1. Lithium-ion Batteries: Lithium-ion batteries have become widely used in recent years, offering advantages such as high energy density, long life, and low self-discharge. Lithium-ion batteries offer stable performance, operate over a wide temperature range, and have high charge and discharge efficiency, making them suitable for a variety of energy storage scenarios.
2. Lead-acid Batteries: Lead-acid batteries are a traditional energy storage battery with mature technology and low cost. However, they suffer from low energy density, heavy weight, long charging times, and environmental pollution, leading to their gradual replacement by lithium-ion batteries in many applications.
3. Nickel-cadmium Batteries: Nickel-cadmium batteries offer excellent low-temperature performance and a long lifespan, but they exhibit a memory effect, meaning that if the battery is not fully discharged, its capacity gradually decreases. Furthermore, the cadmium in nickel-cadmium batteries is harmful to humans and the environment.
