Is Lithium Ion Battery For Solar Storage The Best?
The newest trend in the production of clean energy implies replacing the Lead Acid battery with the lithium-ion battery for solar storage. The later one has turned out to be more effective than its once all-mighty competitor.
These Lithium-ion battery types of energy accumulators were invented in 1970. They did not take the market straight away because they needed improvement. In 1985, Japanese manufacturers showed the world an enhanced product, which was released six years later.
Initially, it was used for boosting the functioning ability of mobile phones and laptops. Soon, manufacturers become aware of its potential and started to produce larger cells with application in the electricity industry.
Process That Gives Life To A Lithium-Ion Battery
Unlike their simple AA battery counterparts, the AA lithium ion battery are rechargeable. Li-Ion pile up power using lithium ion battery chemistry. This means their reagents can be regenerated if electricity passes through the inside. The empty battery is connected to a charger, which uses electricity to reverse the initial chemical reactions.
All lithium-ion battery including the ones employed for solar energy stocks, have two electrodes: a positive one made of a lithium compound and a negative one made of carbon. They are connected through an electrolyte, which allows the ions to move between the electrodes.
After discharge, the ions move from the carbon electrode towards the lithium one. The situation is inverted during the recharge process. Unfortunately, this back and forth process cannot last forever. In time, the electrodes swell and shrink.
Imagine your favorite clothes gradually losing their shape and wear out as you use them and wash them. Eventually, they cease to fit you perfectly. Similarly, the ions no longer match with the structure of the electrodes.
Lithium-Ion Battery For Solar Power Storage
Lithium is the lightest metal and therefore and it has the highest electrochemical potential. As a consequence, it has a superior electrical density. At the same time, it is a very reactive element, which means it can store huge amounts of energy. These qualities attracted the attention of innovative researchers who wanted an alternative to the lead-acid accumulators.
The LI-IONs are widespread nowadays. You find them on the market in three different formats:
The last ones have corrugated sides and the adjacent cells separated by air gaps. These two combined elements boost the cooling process.
The batteries were designed to hold the surplus electricity produced photovoltaic panels. The solar panels function while the sun shines outside. So, at the end of the day, you have lots of generated power. There are three options:
To store the excess electricity is a prudent choice.
Plus, using stored power later reduces your electricity bill. There may be weeks when your solar panel electricity-generating device may not cover the electricity demands of your household. In those periods the stored battery power can assist in providing some capacity.
