Batteries are actually a core part of most technological devices being manufactured. They are in smartphones, tablets, computers, automobiles, drones, airplanes, ships, inverters, trains, satellites and so many other inventions. The core factor about batteries is that it is chemical energy that is being converted to electrical energy and it involves 3 major components. These are Cathode, Anode and Electrolyte. Batteries have evolved over the years, having gone through series of changes such as different phases of chemical combinations and implementations. We have seen the evolution of batteries from Voltaic Pile to Daniell Cell; then from Lead-Acid to Nickel Cadmium battery, which further evolved to Alkaline Battery; Nickel-Metal Hydride (NiMH) and we are currently down to Lithium-ion battery. All these batteries come in different shapes, sizes, power capacities and other unique features. All these features determine their output, lifespan and capabilities. The major aim of this article is to discuss the lithium ion battery pack.

NEW ERA: According to research, there has been a major increase in the sales of lithium ion batteries.

For instance, in 2005 alone, the sales of lithium-ion batteries grew up to about $4900mil. By 2015 the sales have further increased to about $15200mil, of which $4800mil comes from the automotive industry alone.

The research also shows that the sale of lithium ion batteries in America is presently at 0.3% but is expected to reach another 10% increase by 2020 based on the projection that there would be increase in the total number of cars on the road that are battery EVs. A further increase of about 35% is expected by 2035.

The growth rate in China, Europe, and Japan is much higher compared to that of the USA. Based on statistics, the US will be consuming 1900TWh of lithium ion battery pack by 2035. This is the equivalent needed to power the whole of US for 160days.


FUTURE: Battery technology is still expected to keep developing and evolving although presently there hasn’t been any new major battery invention since the evolution of lithium ion battery packs.

Lithium ion battery packs are configured such that they can deliver the desired voltage, power density, and capacity.


The contents and the proportion of the combination of raw materials may have been changed or reconfigured to enhance its capabilities, but more work and improvement still has to go into the battery technology.


The aim of battery manufacturers is to reach over 700Wh/kg as against the 400Wh/kg that is in use today. The main projection is that by 2020, 75% of batteries will likely contain more cobalt along with better anodes, cathodes and boosting electrolytes.



From the above, it is obvious that lithium ion battery pack cheaper and more efficient than the other existing batteries, especially in the long run. Not only that, Lithium Air technology is in the works. This will likely offer 10 times the energy density that Lithium ion presently offers. This means that the world of lithium ion battery pack is still here to stay, at least for the next 50 years, which makes it one of the biggest developing technology sectors.
