They also exhibited a reduced memory effect, although it wasn’t entirely eliminated. While less toxic than cadmium, NiMH batteries still suffer from a high self-discharge rate, meaning they lose their charge even when not in use. They also tend to have a shorter lifespan compared to Lithium Ion, making them less desirable in modern laptops. Nickel Metal Hydride batteries bridged the gap to the modern battery.
Lithium Ion: The Reigning Champion
Lithium Ion batteries, commonly referred to as Li-Ion, have become the dominant technology in modern laptops. They boast a high energy density, meaning they can store a lot of power in a relatively small and lightweight package. Li-Ion batteries also exhibit a low self-discharge rate and are not affected by the memory effect. However, they are not without their drawbacks. Li-Ion batteries age over time, regardless of whether they are used or not. They are also susceptible to overheating and, in rare cases, can swell or even catch fire if damaged or improperly manufactured. The chemistry behind Lithium Ion batteries involves the movement of lithium ions between the anode and cathode during charging and discharging.
Lithium Polymer: Form Factor Flexibility
Lithium Polymer batteries, often abbreviated as Li-Po, are similar to Li-Ion but use a polymer electrolyte instead of a liquid one. This allows manufacturers to create batteries in a wider variety of shapes and sizes, making them ideal for slim and lightweight laptops. Li-Po batteries can also offer higher discharge rates in some cases, providing better performance for demanding tasks. However, they can be more fragile than Li-Ion batteries and are more prone to swelling if damaged. The differences between Lithium Ion and Lithium Polymer often relate to specific application requirements.
