Energy is the lifeblood of every electronic device, without which our gadgets are just mere well-crafted plastic, glass, or metal shapes. Generally, energy is sourced from a different technology, it could be from the sun (solar energy), wind turbine, hydropower, or from chemical sources like batteries.
Battery technology makes up 99% of the power source used by smartphones and other consumer electronic products. however, there are different materials used to make these batteries, each material comes with different properties which in turn determines the battery energy density, weight, and other specifications.Before we proceed let’s talk
about energy storage a bit; electrical energy can be stored for future use, to
make this work a device called Battery is used, a battery is an energy storage
device, it does this through a chemical reaction within it, there are basically
two types of storage device in the market, that is primary and secondary storage
device, the primary storage device is
not rechargeable but is designed to work and be replaced when depleted, but
secondary storage device or batteries are rechargeable; they are the types
found in our phones and every rechargeable device.
In this article you are going to
learn about the different battery technologies found in smartphones, you are
going to see their strength and limitations to help you make a better choice
when purchasing another phone or any other rechargeable device.
Smartphones use several types of batteries, primarily based on their energy density, recharge cycles, and safety. The main types of batteries used in smartphones are:
Lithium-Ion (Li-Ion) Batteries:
- Most common type of battery in smartphones today.
- High energy density, long cycle life, and low memory effect.
- Lightweight and rechargeable, providing high capacity in small form factors.
- A variation of lithium-ion technology but using a polymer electrolyte instead of a liquid one.
- Thinner and more flexible in design, allowing for slimmer smartphones.
- Offers improved safety with less risk of leaking or explosion.
- Used in early mobile phones, but largely phased out due to lower energy density and shorter life span compared to lithium-based batteries.
- Early generation of rechargeable batteries used in some early mobile devices.
- Suffered from a significant "memory effect," reducing capacity over time, and environmental concerns due to cadmium toxicity.
Modern smartphones almost exclusively use Li-Ion or Li-Po batteries due to their superior performance, compact size, and better safety features, so when next you are buying a new gadget, glance through the battery spec to ensure it's using the latest technology.
