Consumer electronics is clearly becoming intelligent, portable, flexible, and convenient. Appliance manufacturers are increasingly requiring smaller size, lighter weight, longer runtime and more convenience into their products. To meet the need of these demanding applications, batteries must feature:
The use of lithium ion batteries and lithium polymer batteries has become commonplace in many consumer electronics due to their higher energy density, lighter weight, longer lifespan, decreased enviromental impact and ability to hold a charge for long periods of time. Lithium polymer batteries are based on lithium ion technology. They are fundamentally a subset of lithium ion batteries. The general difference between them is the characteristic of the electrolyte used. Tradtional lithium ion batteries use a liquid-based electrolyte while the electrolyte used in lithium polymer batteries is either solid, porous, or gel-like.
Lithium ion batteries have a range of advantages over other battery technologies. One of the most significant advantages of lithium ion batteries is their high specific energy. Specific energy is also referred to as massic energy or gravimetric energy density. It is simply energy per unit mass. It is a measure of how much energy a particular battery contains in comparison to its weight. A battery with high specific energy compared to its counterparts means that it can provide a higher level of energy without sacrificing its weight. It is essentially lighter. Lithium ion batteries have higher specific energy than other types of non-lithium ion rechargeable batteries. They can also be designed and fabricated with a wider range of energy densities in accordance with different weights.
Lithium polymer batteries have flexible form factor. Because of the aforementioned higher specific energy and a higher degree of freedom in fabrication, a critical advantage of lithium polymer batteries is that they are ideal in applications in which space and weight are an important manufacturing consideration. Examples of these applications include ultraportable computers or ultrabook laptops, smartphones and tablet computers, lightweight electric vehicles, and radio-controlled aircraft or unmanned aerial vehicles such as drones. Lithium polymer batteries can be produced in varieties of shapes and sizes. Hence, this is the reason why they have become an ideal power storage solution for mid-range to flagship consumer electronic devices.
In terms of safety, lithium ion batteries are considered relatively safe but overheating or overcharging can lead to severe damage or even detonation. Lithium polymer batteries are generally safer because they use a solid, porous, or gel-like polymer electrolyte instead of a liquid electrolyte. They do not explode due to gas built-up and not leak in case of excessive heat. They simply swell or expand in size. The absence of leakage also means that the electronic components of a particular device are safe from battery issues.
Another advantage of lithium ion batteries is that they have low self-discharge rate and do not lose their charging capacity as fast as their traditional counterparts. Because of their durability feats, they usually have a longer lifespan and are more reliable. The overall lithium ion technologies have been improving over the years to make them more durable.
