Introduction to accumulators and lithium batteries

Battery and lithium battery are two different kinds of battery, consumers do not know when to choose the better, the performance of these two batteries do not understand, here to give you an introduction.

Introduction to Batteries and Lithium Batteries: Batteries

StorageBattery is a device that converts chemical energy directly into electric energy. It is a rechargeable battery designed by reversible chemical reaction to achieve recharging. It usually refers to lead-acid battery, which is a kind of battery and belongs to secondary battery. Its working principle: when charging the use of external electric energy to regenerate internal active substances, the electric energy is stored as chemical energy, need to discharge the chemical energy again into electrical energy output, such as life commonly used mobile phone battery.

It uses a lead substrate grid (also known as a lattice) filled with spongy lead as a negative electrode, a lead substrate grid filled with lead dioxide as a positive electrode, and a dense dilute sulfuric acid as an electrolyte. When the battery is discharged, the metal lead is the negative electrode, and the oxidation reaction occurs to produce lead sulfate. Lead dioxide is the positive electrode, which undergoes a reduction reaction to form lead sulfate. When a battery is charged by direct current, the poles form elemental lead and lead dioxide, respectively. After the power is removed, it returns to its pre-discharge state and forms a chemical battery. Lead battery can be charged and discharged repeatedly, its single voltage is 2V, battery is composed of one or more batteries, referred to as batteries, the most common is 6V, other 2V, 4V, 8V, 24V batteries. For example, the battery used on the car (commonly known as battery) is 6 lead batteries in series into 12V battery pack.

Battery and Lithium battery Introduction: Lithium battery

"Lithium battery" is a type of battery made of lithium metal or lithium alloy as anode material and using a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, preservation and use of lithium metal require very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now.

Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain lithium in the metallic form and are rechargeable.
