The Difference Between the Energy Storage Principle of Solar Battery and Lithium Battery

Most of today’s smart electronic products use rechargeable batteries lithium. Especially for mobile electronic devices, due to the characteristics of lightness, portability and multiple application functions, users are not limited by environmental conditions during use, and the operation time is long. Therefore, batteries lithium are still the most common choice despite their weakness in battery life.

Although solar battery and batteries lithium sound like the same kind of products, they are actually not the same. There are still the most essential differences between the two.

To put it simply, a solar battery is a power generation device, which itself cannot directly store solar energy, while a lithium battery is a type of storage battery that can continuously store electricity for users to use.

1. The working principle of solar battery (can not do without sunlight) 

Compared with batteries lithium, one disadvantage of solar battery is obvious, that is, they cannot be separated from sunlight, and the conversion of solar energy into electricity is synchronized with sunlight in real time.

Therefore, for solar battery, only during the day or even sunny days is their home field, but solar battery cannot be used flexibly as long as they are fully charged like batteries lithium.

2. Difficulties in “Slimming” of solar battery

Because the solar battery itself cannot store electrical energy, it is a very big bug for practical applications, so the developers have an idea to use the solar battery in combination with the super-capacity battery, and the battery is one of the most widely used solar power supply systems. Class large-capacity solar battery.

The combination of the two products makes the solar battery that are not small in size become more “big”. If they want to be applied to mobile devices, they must first go through the process of “thinning”.

Because the power conversion rate is not high, the solar battery’s sunshine area is generally large, which is the biggest technical difficulty faced by its “slim down”.

The current limit of solar energy conversion rate is about 24%. Compared with the production of expensive solar panels, unless the solar energy storage is used in a large area, the practicality will be greatly reduced, not to mention the use of mobile devices.

3. How to “thin” solar battery?

Combining solar energy storage batteries with recyclable batteries lithium is one of the current research directions of researchers, and it is also a useful way to mobilize solar battery.

The most common solar battery portable product is the power bank. Solar energy storage converts light energy into electrical energy and stores it in the built-in lithium battery. The solar mobile power supply can charge mobile phones, digital cameras, tablet computers and other products, which is both energy-saving and environmentally friendly.
