Chapter 2: Battery Basics: Understanding
the Core
As we venture deeper into the realm of battery reconditioning, it becomes essential to
build a strong foundation of understanding about batteries themselves. This chapter is
dedicated to unraveling the basics of batteries, their types, workings, and nuances. A
solid grasp of these fundamentals is not only crucial for effective reconditioning but
also enhances our ability to use and maintain these power sources more efficiently.
The Anatomy of a Battery
At its core, a battery is a device that stores energy in chemical form and converts it into
electrical energy through an electrochemical reaction. This process involves three key
components: an anode (negative electrode), a cathode (positive electrode), and an
electrolyte, which facilitates the movement of ions between the electrodes.
Batteries, in their simplest form, consist of three main components:
1. Anode (Negative Electrode): This is where oxidation occurs, releasing electrons.
2. Cathode (Positive Electrode): This is where reduction takes place, accepting
electrons.
3. Electrolyte: A chemical medium that allows the flow of electrical charge between
the cathode and anode.
When a battery is connected to an electrical circuit, chemical reactions occur at the
electrodes that generate a flow of electrical energy to the circuit.
12

Types of Batteries
Batteries come in various types, each with unique characteristics and uses. The most
common types include:
1. Lead-Acid Batteries: Used in vehicles and backup power systems, they are
known for their high power-to-weight ratio. These are one of the oldest types of
rechargeable batteries. They have a high power-to-weight ratio, making them
ideal for motor vehicles where weight and space are crucial. However, they
require regular maintenance and are less suited for devices requiring a steady
power supply over longer periods.
2. Nickel-Cadmium (NiCd) Batteries: Known for their robustness and long life, they
are used in a range of applications from power tools to aviation. They suffer from
the 'memory effect' and require periodic full discharges to maintain capacity.
3. Nickel-Metal Hydride (NiMH) Batteries: Offering a higher capacity than NiCd
batteries, NiMH batteries are used in similar applications but are more
environmentally friendly. They have a shorter lifespan and are more sensitive to
high temperatures.
4. Lithium-Ion Batteries: These are popular in portable electronics due to their high
energy density and low self-discharge rate. They are more expensive to produce
but offer longer lifespans and do not suffer from the memory effect.
Understanding Battery Chemistry
Each type of battery operates on a specific chemical principle. For example, in a
lead-acid battery, the reaction between lead dioxide (cathode), sulfuric acid (electrolyte),
and lead (anode) creates electrical energy. In lithium-ion batteries, lithium ions move
between the anode and cathode during discharge and charge cycles.
Each battery type operates on a specific chemical principle. For instance:
● In lead-acid batteries, the electrochemical reaction involves lead dioxide and
sulfuric acid, producing lead sulfate and water.
● Lithium-ion batteries rely on the movement of lithium ions between the cathode
and anode during charge and discharge cycles.
13

Lead-Acid Batteries:
● The basic chemistry of lead-acid batteries involves lead (Pb) and lead dioxide
(PbO2) as the active materials in the electrodes, submerged in an electrolyte of
sulfuric acid (H2SO4).
● During discharge, the lead dioxide (positive plate) and the lead (negative plate)
react with the sulfuric acid to produce lead sulfate (PbSO4) and water (H2O).
This reaction releases electrons, creating electrical current.
● The chemical reaction during discharge is as follows:
PbO2+Pb+2H2SO4→2PbSO4+2H2O
● When recharging, the process is reversed, converting the lead sulfate and water
back into lead dioxide, lead, and sulfuric acid, thereby restoring the battery's
ability to generate electricity.
Nickel-Cadmium (NiCd) Batteries:
● NiCd batteries operate based on the reaction between nickel oxide hydroxide
(NiOOH) and cadmium (Cd).
● During discharge, the nickel oxide hydroxide is reduced to nickel hydroxide
(Ni(OH)2), and the cadmium oxidizes to cadmium hydroxide (Cd(OH)2),
generating electricity in the process.
● The chemical reactions can be summarized as follows:
Cd+2NiOOH+2H2O→Cd(OH)2+2Ni(OH)2
● On charging, these reactions are reversed, regenerating the original materials.
Nickel-Metal Hydride (NiMH) Batteries:
● In NiMH batteries, the positive electrode is nickel oxyhydroxide (NiOOH), similar
to NiCd batteries, but the negative electrode uses a hydrogen-absorbing alloy
instead of cadmium.
● During discharge, the nickel oxyhydroxide gets reduced while the
hydrogen-absorbing alloy gets oxidized, releasing electricity.
● The absence of toxic cadmium makes NiMH batteries more environmentally
friendly than NiCd batteries.
14

Lithium-Ion Batteries:
● Lithium-ion batteries use an intercalated lithium compound as the electrode
material, typically lithium cobalt oxide (LiCoO2) at the cathode and graphite at
the anode.
● During discharge, lithium ions move from the anode to the cathode through the
electrolyte, while electrons flow through the external circuit, providing electric
power.
● On charging, lithium ions move back to the anode, storing energy in the process.
● The high energy density of lithium-ion batteries results from the lightweight and
high potential energy of lithium ions.
Understanding these chemical reactions is crucial for battery reconditioning. Each
battery type has its own set of challenges and requirements for reconditioning. For
instance, lead-acid batteries may suffer from sulfation, where lead sulfate crystals
harden on the battery plates, requiring specific treatments to dissolve these crystals.
Similarly, NiCd batteries might need a full discharge to counteract the memory effect,
while lithium-ion batteries demand careful handling to prevent overcharging, which can
lead to overheating and potential hazards.
By grasping the intricate details of battery chemistry, one can better diagnose issues,
apply the right reconditioning techniques, and ultimately prolong the life and efficiency
of batteries. This knowledge forms the bedrock upon which successful battery
reconditioning and maintenance are built.
Voltage, Capacity, and Energy Density
● Voltage refers to the electrical potential difference between the two terminals of
a battery. It determines the amount of electrical energy the battery can deliver. In
simple terms, it is the 'strength' of the electrical output of the battery.
● Capacity is measured in ampere-hours (Ah) and indicates the amount of electric
charge a battery can store. A higher capacity means the battery can power a
device for a longer period.
● Energy Density reflects how much energy a battery contains in relation to its
weight or volume, a critical factor in portable electronics. Higher energy density
batteries are preferable for portable devices.
