Why Lithium Ion Battery is Used

Why Lithium Ion Battery is Used

Lithium ion batteries are used in a wide variety of applications. They are especially popular in electronics and medical devices, and they are extremely energy-efficient. But there is a drawback to lithium-ion batteries: they can sometimes burst into flames, which is something only about two to three packs out of a million will experience. This is because lithium-ion batteries are highly sensitive to temperature, which leads them to degrade quickly. The degrading process begins as soon as the batteries leave the factory.

Energy density

The energy density of lithium-ion batteries is the highest of all rechargeable battery technologies. It ranges from 100 to 265 Wh/kg. This means that lithium-ion batteries can store as much energy as six gallons of gasoline. This means that they can power many devices that use electrical power.

The higher the energy density of a battery, the higher its energy delivery. However, higher energy density can also pose a safety problem. Batteries with a higher energy density are more prone to thermal events.

Thermal stability

Thermal stability of lithium ion batteries is an important aspect to consider for lithium ion batteries. The temperature plays a major role in the performance of the battery and can cause undesirable side reactions. High temperatures can also lead to the rupture of the battery, which can be dangerous. A typical ARC test curve shows the thermal stability of a pouch type LIB.

The physical structure of the battery is also important. This can be achieved through a variety of means. The electrodes need to be sufficiently stable to avoid ion migration through the electrolyte. This means that materials must be chosen carefully to ensure the stability of the device.

Safety

Lithium ion batteries are safe, but they are not indestructible. The battery material can become unstable under high demand conditions, causing a thermal runaway, which can cause the battery to burn. The thermal runaway energy is approximately 5.4 times the electrical energy in the battery.

Lithium ion batteries have a higher temperature than traditional aqueous-electrolyte batteries. This temperature rise can be caused by a variety of conditions, including improper use, internal manufacturing defects, and an incident that affects the battery cell.

Range

The operating temperature range of lithium ion batteries is from -20°C to 60°C. However, the discharge rate varies greatly. The range of Lithium-Ion batteries is more limited than that of Lithium-Polymer batteries. Lithium-Ion batteries have a maximum discharge rate of 2C and Lithium-Polymer batteries have a maximum discharge rate of 3C. The nominal voltage range of Lithium-Ion batteries is 3.70V and Lithium-Cobalt oxide batteries are 3.60V.

Lithium-ion batteries are commonly used in electric vehicles. They are also used in advanced electric wheelchairs and motorcycles. Even radio-controlled models use lithium-ion batteries. They can have a variety of positive and negative electrode materials.

Cost

The cost of lithium ion batteries is still high, but prices are expected to come down in the coming years. While battery makers and large customers generally do not release their cost structures, market reports do provide some insights into the overall cost figure. Consumer-grade batteries have been priced around $100 per pack, and this price is likely to continue to fall in the future.

Cost estimations are dependent on many factors, including technological and manufacturing processes. Early time-specific studies tend to have high ranges, but they can be explained by the longer forecasting periods, technological learning, and literature-based projection. Experts are often in disagreement on the cost of a battery, and this disagreement is also reflected in the average estimate. In addition, different technological assumptions can have a significant impact on battery costs.

Recyclability

While the recyclability of lithium ion batteries is an important issue, it is also a source of concern. The lithium used in EVs is a rare material and therefore will need to be replaced or recycled over time. The good news is that some companies are implementing programs to help recycle these batteries. These efforts may have long-term positive effects on the environment.

In the US alone, only one percent of lithium-ion batteries are recycled. This is far lower than the 99 percent recycling rate for lead-acid batteries. This is especially concerning because most lithium-ion batteries are used in gas vehicles and power grids. Other challenges with recycling lithium-ion batteries include their rapidly evolving technology, the expensive transportation of hazardous materials, and inadequate government regulation.
