Types of batteries
The first phase of the battery guide will take you to study batteries and explain how to correctly grasp each type of battery.
Chemical composition
A battery is a device that converts chemical energy into electrical energy. The chemical composition of a battery determines its performance and battery characteristics.
Lead-acid battery: Metallic lead, lead dioxide, lead sulfate, and sulfuric acid are all components of lead-acid batteries. The negative electrodes are metallic lead with trace amounts of other metals, such as calcium, tin, and antimony.
Alkaline battery: High-density manganese dioxide, potassium hydroxide, and zinc are precisely combined to make an alkaline battery. Reducing the manganese dioxide cathode and oxidation of the zinc anode in an alkaline battery causes energy generation.
Lithium battery: Lithium cobalt oxide (cathode) and graphite (anode) is the most common chemical compositions. Other cathode components include lithium iron phosphate and nickel cobalt manganese. Therefore, lithium-ion battery can usually be divided into lithium iron phosphate battery and ternary lithium battery according to the cathode material.
Sodium ion: The anode materials of sodium-ion batteries usually use compounds such as sodium nickel cobalt manganese oxide (NMC) or sodium iron phosphate (NaFePO4), while the cathode materials use carbon materials or titanium oxides.
Physical structure
The physical structure is also a factor that determines the types of a battery, and they include:
Cylindrical: Cylindrical batteries are a type of battery that have a cylindrical shape. A cylindrical cell comprises sheet-like separators, cathodes, and anodes, that are folded up and packed into a container with a cylinder form. They come in various sizes, including small (coin cell), AA/AAA, C/D, and 21700、26650 and 18650 battery.
Prismatic: A prismatic cell is one whose chemistry is contained within a rigid shell. Its rectangular design makes it possible to stack several units in a battery module effectively.
Pouch: A pouch cell is a polymer battery in which most of the cell’s components are encased in a plastic sheet with an aluminium coating.
Electrolyte type
Electrolyte is one of the important raw materials of batteries. According to the different forms of electrolyte, the types of batteries are also different.
Liquid electrolyte: This battery technology is mostly found in lithium-ion batteries that use polymer gel or liquid electrolytes.
Solid electrolyte: This is a battery technology using solid electrodes and a solid electrolyte.
Semi-solid electrolyte: Semi-solid electrolyte have both solid and liquid-like properties, which makes them ideal for use in batteries and other energy storage systems.Semi-solid batteries are also developed accordingly.
Application
Batteries are divided into different types due to their different applications.
Power battery: rechargeable batteries used to start electric vehicles, such as cars, motorcycles, e-bikes,golf carts etc.
Consumer Electronics: Smartphones, tablets, computers, cameras, MP3 players, consoles, handheld games, shavers, and many more common electric and electronic devices are all powered by rechargeable batteries.
Energy storage: Applications for energy storage are utilized to switch between high-power sources and satisfy peak power demands quickly, such as Solar energy storage system, emergency power supply, household energy storage, industrial and commercial energy storage etc.
Battery capacity
Everything you need to know about voltage can be found in this battery guide.
Definition of battery capacity
The capacity of a battery refers to the amount of energy it can store and release during the discharge process, and its unit is “Ah”, which stands for “ampere hour,” which is the unit of capacity.
Factors affecting battery capacity
Charge and discharge rates: The discharge capacity will be lowered if the charging depth is shallow. Overcharging the battery will influence the chemical active components and create irreparable damage, diminishing the capacity and life of the battery.
As a result, an adequate charging rate, upper limit voltage, and constant voltage cut-off current must be chosen to provide optimal charging efficiency, safety, and stability while reaching charging capacity.
Temperature: Temperature plays a crucial role in battery performance and capacity.Exposure to extreme temperatures, whether high or low, can cause permanent damage to the battery, reducing its overall lifespan. It’s important to keep batteries within their optimal temperature range.
History and age: The capacity of a battery is significantly impacted by the battery’s age and history. The battery capacity will fade for a certain number of charge/discharge cycles.
Battery voltage
Through this phase of battery guide, you will explore another important parameter of the battery-voltage.
Definition of battery voltage
One of a battery’s most important properties is its voltage, which is governed by the chemical processes occurring inside it, the concentrations of its constituent parts, and the battery’s polarization. The nominal battery voltage is often called the voltage determined from equilibrium conditions.
Factors affecting battery voltage
Voltage change during discharging: As the battery discharges, the charge decreases, and the voltage decreases.
Battery type: The cell voltage of different types of batteries is different. The cell voltage of lithium-ion battery is higher, which can reach 3.2-3.7v, while the voltage of lead-acid battery is 2v.
Temperature: The battery voltage will rise with an increase in system temperature.
Relationship between voltage and capacity
Voltage and capacity are two critical factors for describing battery performance. Battery power is measured by voltage, whereas battery durability is determined by capacity.
However, different battery kinds, such as lithium-ion, lead-acid, and nickel-cadmium, have varying voltage and capacity characteristics.
Connecting numerous cells in series or parallel is a common approach to expand a battery’s capacity or voltage. Connecting batteries in series raises the battery’s overall voltage, whereas connecting cells in parallel raises the battery’s total capacity.
Battery cycle life
The number of cycles refers to the number of times the nominal capacity of the battery can be charged and discharged before significant attenuation occurs.
Battery charging
Choosing suitable battery charger is crucial in determining the product’s battery life and everyday usability. This phase of battery guide will take you to understand the knowledge of battery charging.
The size and kind of the battery being charged determine the charging process (how much voltage or current is used, for how long, and what to do when charging is finished).
Battery charge rate
C-rate control how quickly a battery charges and discharges. A battery’s capacity is typically expressed as 1C, which means that a fully charged battery with a 1Ah rating should deliver 1A for an hour.
Charging method
The charge control IC in lithium battery BMS performs optimum charge control tailored to the lithium-ion battery while keeping an eye on safety and extending battery life. It does this by monitoring the voltage, current, and temperature.
Below are the various types of charging methods:
Constant Current Constant Voltage (CCCV) Charging: Rechargeable batteries like li-ion are frequently charged using the CCCV method. Depending on the voltage of the rechargeable battery, operation alternates between CC charging, which charges at a constant current, and CV charging, which charges at a constant voltage.
Pulse Charging: A charging procedure that avoids sulfation by pulsing the charging current with tiny pulses of frequency. Sulfation, a component of the electrolyte that crystallizes into the lead when using lead-acid batteries and doesn’t conduct power, builds up on the negative electrode side of the battery.
As a result, efficiency is decreased because internal resistance and storage capacity are lowered. Pulse charging works well in these situations because it can successfully break apart these crystalline materials.
Fast charging: The basic principle of fast charging technology is to achieve higher charging power by increasing the charging voltage and current. Under the premise of ensuring battery safety, intelligently adjust charging parameters.
In addition, the fast charging technology also uses an advanced charging algorithm to ensure that the charging power can be adjusted according to the battery state during the entire charging process.
Battery maintenance
Battery maintenance is crucial to maintaining a secure and effective battery experience. But the right way to maintain batteries is frequently disregarded. This phase of battery guide will give you some tips to maintain the battery and introduce the steps of battery recycle.
When it comes to conserving time, prolonging the life of your battery, and safeguarding your equipment, performing maintenance in the proper order is just as important as the maintenance task themselves.
Tips for extending battery life
