Charging Lithium Batteries: The Basics

Lead Acid Charging. When charging a lead – acid battery, the three main stages are bulk, absorption, and float. Occasionally, there are equalization and maintenance stages for lead – acid batteries as well. This differs significantly from charging lithium batteries and their constant current stage and constant voltage stage. In the constant current stage, it will keep it

Can I Charge a Lithium Battery with a Normal Charger?

Lithium batteries require a constant current and voltage during the charging process, and trickle charging can cause overcharging and damage to the battery.

What happens if a lithium-ion battery fails?

In addition to this, the way a lithium-ion battery produces power also generates heat as a by-product. In an uncontrolled failure of the battery, all that energy and heat increases the hazard risks in terms of fuelling a potential fire.

Are lithium ion batteries dangerous?

All types of batteries can be hazardous and can pose a safety risk. The difference with lithium-ion batteries available on the market today is that they typically contain a liquid electrolyte solution with lithium salts dissolved into a solvent, like ethylene carbonate, to create lithium ions.

What happens if a lithium ion battery overheats?

The major issue with lithium-ion batteries overheating is a phenomenon known as thermal runaway. In this process, the excessive heat promotes the chemical reaction that makes the battery work, thus creating even more heat and ever more chemical reactions in a disastrous spiral.

Do lithium ion batteries burn?

Current commercial lithium-ion batteries typically use carbonate as an electrolyte. Carbonates are often volatile and prone to burning. During the thermal runaway process in liquid-state batteries, high temperature drives the vaporization of the electrolyte. The carbonate solvents may spray out and burn outside the battery.
