The Pros And Cons Of Lithium Ion Batteries And Their Technology

Lithium ion battery technology is the advent of electrification that serves as a better solution to stationary power storage and supply. This discovery that makes for the development, innovation, and effective use of renewable energy sources is already in place for the applications for low power-consuming electronics and tools. However, in recent years, extensive research has led to a more evolved stage. Now, the technology gets applied to hybrid electric appliances and vehicles, and solar-powered systems. 

Nevertheless, this technology of lithium-ion batteries comes with its due share of cons. Let us discuss both their beneficial aspects and drawbacks along with a few related details in this article.

Basic Principle behind the Working of Lithium-ion Batteries

The fundamental unit of a lithium-ion battery is its electrochemical cell that comprises a negatively charged cathode, a positively charged anode, a separator, and an electrolyte. 

In the charged state, the anode contains a high quantity or concentration of lithium ions. In the same condition, the cathode remains depleted of them. 

During use or discharge, the positive lithium ions migrate towards the cathode through the electrolyte. The current collector collects and accumulates their associated electrons for use to power an appliance or device. 

For low-energy applications, a single cell represents a battery in its entire essence. For high-power usages, a group of cells packaged in a single pack forms a battery. 

Materials used in Lithium-ion Batteries

Cathode materials for lithium ion batteries can include metal oxides of lithium such as lithium cobalt oxide and lithium manganese oxide. They can also get composed of lithium iron phosphate and vanadium oxides. 

The anode can have graphite, silicon, lithium and its alloys, and intermetallic substances as its constituents.  

Lithium-ion batteries use an electrolyte that can withstand and work with the existing voltage and extremely high temperatures. They must ensure a long shelf life while offering high or superior mobility and transportability to the lithium ions. Hence, to serve this purpose, solid-state, polymer, and liquid electrolytes get used. 

Separators act as a physical barrier between the two charged electrolytes, preventing a short circuit. For liquid electrolyte, foam separators, soaked in the electrolyte, get used. 

Pros and Cons of the Components of a Lithium-ion Battery

The overall material cost of raw materials, manufacture, labor and other miscellaneous aspects add up to the total expense spent behind a lithium ion battery. Nevertheless, the investment behind this technology is worthwhile. These batteries come with and proffer high amounts and quantities of energy and power for extended periods even after extensive and abusive use. 

Lithium ion batteries have built-in and automatic thermal shutdown systems and mechanisms and state-of-the-art thermal management features. They also have adequate and suitable protection against excessive charging, polarity reversal, low voltage, overheating, and various other faults and fluctuations. Liquid electrolytes provide mechanical stability, flame retardance, and chemical resistance.

As a con, the solid electrolytes show poor performance at low-temperature conditions, proffering over less than half of their original capacities and stored power. It can get owed to the reduced discharge rates and energy. Another drawback lies in the truth that lithium-ion batteries are not entirely safe for use and exposure to humans. They can undergo short circuits, breakdowns, overcharging, and over-discharging. In addition to these, lithium-ion batteries can overheat and result in small-scale fires. They can also lose their stored charge over time.For more about the pros and cons of lithium ion batteries and their technology,you can pay a visit to JB Battery China at for more info.
