About Me

Hello!
I am Harshad, an Engineer specializing in energy storage.
I have been working in different areas of energy storage technology for a while. I have designed and tested Li-ion battery packs and battery management systems for various applications. I also have experience working with a Lithium-ion battery (LiB) material research. As an Electrical engineer, working with material gives me a deeper insight into LiB technology.

As entire humanity is facing ill effects of global warming like never before, governments around the globe are pushing hard for clean transportation. Since one of the most important components required for clean transport is the energy storage device, I thought about starting a blog addressing fundamental knowledge, current problems, and opportunities for improvement in the area of energy storage, green transport, and clean technology. I hope this blog will help you understand the state of the art technology. Please feel free to drop me a message regarding any professional consultation related to these areas.

Decoding Li-ion Cell Voltages Of Different Chemistries

Image
While deciding an optimal Lithium-ion cell chemistry for different applications, I came across this question quite a few times, ' Why different Li-ion cell chemistries have different terminal voltages? ' There are numerous LiB chemistry types available in the market. e.g. Lithium Cobalt Oxide (LCO), Li Nickel Cobalt Aluminum Oxide (NCA), Lithium Tantalate Oxide (LTO), Lithium Iron Phosphate (LFP), etc to name a few. However, each and every battery type has its positive-negative points. Although the working principle of all these chemistries is the same, their terminal voltages are different. For example, LCO cells can go up to 4.25V, NCA can be charged up to 4.2V whereas LFP and LTO type cells can have a maximum of 3.8V and ~2.5V respectively. This difference in the voltage has a very large effect on the battery capacity (since energy capacity is directly proportional to the battery voltage). In this blog, I will answer 'Why different LiB chemistries have different

How Does The LiB Work?

Image
It has been almost three decades that the Lithium-ion Battery (LiB) was first commercialized in 1991 by Sony (I have worked at the same R&D lab! 😊).  LiBs has shown good reliability over time and now it is the most sought after energy storage chemistry for automotive and numerous other consumer applications. In this blog post, I will describe a fundamental working mechanism of a LiB. A large number of resources are available on the internet for getting insight into the LiB mechanism. I will try to give a consolidated and brief overview of: LiB charge-discharge mechanism Non-idealities in LiB operation Overview of Energy Storage Devices Figure 1 shows different types of energy storage mechanisms ranging from mechanical, electrical and chemical energy storage (it is not an all-inclusive picture. Numerous other techniques exist for storing different forms of energies)  Out of those main three types, Chemical energy storage devices are called 'Batteries' in

The Problem With Fast Charging

Image
One of the major drawbacks of EV over the IC engine vehicle is charging time. As we know filling the gasolene tank only takes a few minutes. however, for the same drive range, it takes about an hour for an EV to recharge itself even with a fast charger. In this blog, I will discuss some of the problems with fast charging in the case of LiB. Before we dive into what happens inside LiB when we try to fast charge, I would like to talk a bit about LiB construction.  LiB Construction In my previous blog, ' How Does The LiB Work? ', I indicated LiB as a simple construction with 2 electrodes (Anode and Cathode) placed in an electrolyte. As shown in figure 1. Figure 1. Oversimplified LiB However, the construction of an actual Lithium-ion cell is not at all like what I have shown above! In an actual cell, Anode and Cathode are placed very close to each other in order to pack as much active material (material which takes part in intercalation/de-intercalation) as poss
