Lithium Ion Cylindrical Cells Vs. Prismatic Cells
Cylindrical and Prismatic Cells are the most common options on the market for building Lithium Batteries. Before you purchase a battery cell for your application consider the following advantages and drawbacks of each type of cell.
Cylindrical Cells
Cylindrical cells are the most common cell type in use today. This design allows for better automation processes and techniques that increase consistency and lower cost.
Prismatic Cells
Prismatic cells have gained popularity because their large capacity and prismatic shape that make it easy to connect 4 cells together and create a 12V battery pack.
Cylindrical Advantages
Compared to prismatic cells, cylindrical cells can be produced much faster so more KWh per cell can be produced every day equaling lower $ per KWh. The electrodes in a cylindrical cell are wound tightly and encased in a metal casing, This minimizes electrode material from breaking up from the mechanical vibrations, thermal cycling from charging and discharging and mechanical expansion of the current conductors inside from thermal cycling. Many cells are combined in series and in parallel to increase voltage and capacity of the battery pack. If one cell goes bad, the impact on the entire pack is low. With prismatic cells if one cell goes bad it can compromise the whole battery pack. Cylindrical cells radiate heat and control temperature more easily than prismatic cells.
Prismatic Disadvantages
Prismatic cells are made up of many positive and negative electrodes sandwiched together leaving more possibility for short circuit and inconsistency. The higher capacity makes it difficult for the BMS to protect each cell from over charging and dissipating heat. The larger cell size minimizes the possibility for automation leading to a lower degree of consistency. The internal electrodes can easily expand and contract causing deformation which can lead to a internal short circuit and are more prone to swelling similar to lead batteries.
Electric Vehicle Advantage
An electric vehicle, also known as an EV, is powered fully, or partially, by an electric motor and E-Vehicle battery pack. EVery auto manufacturer in the world has an EV on the road right now or is close to releasing one, with many committed to electrifying their entire line-up over the next 10-15 years.
The Electric Motor Advantage
EVs have better acceleration than gas cars. That’s because electric motors deliver full torque right away, unlike internal combustion engines that need to gear up. Electric motors are an incredibly efficient and durable technology, meaning less maintenance and a longer life time than gas engines.

The Battery Advantage
Electric vehicles use lithium-ion batteries, the same type of battery used in smartphones and laptops. EV batteries hold their charge for weeks at a time and are quick and easy to recharge. EV batteries are 90% recyclable and many companies are looking at re-purposing used-EV batteries for second-life energy storage. This means that at the end of your car’s life, the battery still has value, unlike old gas engines that are bound for the scrapyard.
An electric car, or electric vehicle, is powered fully or partially by an electric motor and battery pack. There are two types of electric car:
1.Fully Electric Cars are powered 100% by electricity and have zero tailpipe emissions.
2.Plug-in Hybrid Electric Cars have small battery packs for short all-electric driving distances (20-80 km) before a gasoline engine or generator turns on for longer trips. Plug-in hybrids differ from gasoline and diesel hybrids in that they provide dedicated all-electric driving distances.
How to take care of your electric two wheels battery
Electric Two-wheeler and Electric Bicycles are becoming very popular means of transportation. Either you want to be environment friendly or you want to avoid public transport in the Covid19 affected world, electric two-wheeler provides a very good option.
There are many advantages of these two wheelers
1. Cheap to operate: Compared to their petrol counterparts, these vehicles are cost effective to operate.
2.Low maintenance needs: In an electric two-wheeler, there is nothing complicated to maintain. You need to make sure you buy your vehicle from a good quality manufacturer and the lithium ion battery is covered by 3-year warranty. For 3 years you will not incur any maintenance cost related to the drive system or the battery. On the other hand for a petrol scooter, you must change engine oil and do checkups based on km driven to keep the vehicle healthy and operational.
3.Never visit a gas station: In today's Covid19 affected world, not going into a public place and being able to charge at home is a great advantage.
