There are many advantages to using a li-ion cell battery. As a result, the technology is being used increasingly for a huge number of widely varying applications. Everything from small electronic devices, through smartphones and laptops to vehicles and many other applications.
The advantages of Li-ion technology mean that these batteries are finding an increasing number of applications, and as a result, a huge amount of development is being invested in them.
The Li-ion battery advantages include:
High energy density: High energy density is one of the chief advantages of lithium-ion battery technology. With electronic equipment such as mobile phones needing to operate longer between charges while still consuming more power, there is always a need for batteries with a much higher energy density. In addition to this, there are many power applications from power tools to electric vehicles. The much higher power density offered by lithium-ion batteries is a distinct advantage. Electric vehicles also need battery technology that has a high energy density.
Self-discharge: One issue with many rechargeable batteries is the self-discharge rate. Lithium-ion cells are that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms. It is typically around 5% in the first 4 hours after being charged but then falls to a figure of around 1 or 2% per month.
Low maintenance: One major lithium-ion battery advantage is that do not require maintenance to ensure its performance.
Ni-Cad cells required a periodic discharge to ensure that they did not exhibit the memory effect. As this does not affect lithium-ion cells, this process or other similar maintenance procedures are not required. Likewise lead acid cells require maintenance, some needing the battery acid to be topped up periodically.
