Moreover, the cycle life of lithium-ion batteries is one of its limitations. The battery degradation and capacity loss over time are caused by the side reactions, which occur on the surface of the particle of the active materials as well as in the electrolyte. The design of the battery electrode structure need to be considered to mitigate side reactions. Consequently, any change of the porosity, thickness, and particle size can affect the specific energy, specific power, discharge capacity, and battery lifetime. Therefore, a multi-objective design optimization framework was developed in my second publication to investigate the optimal solution of the battery design. The most important part of this framework a 2D electrochemical battery model is coupled with comprehensive side reactions in both anode and cathode electrodes to predict the battery capacity loss over hundreds of cycles. Furthermore, the framework is an important tool to design the batteries as various objectives need to be considered.

Next generation of batteries
To achieve higher energy density and a longer lifetime for batteries, my future research focus on the next generation of batteries-solid-state batteries, such as, Metal-Air and Metal-Sulphur batteries. Comparing with lithium-ion batteries, the solid-state batteries have solid electrolyte instead of liquid electrolyte which provides high
The performance of the electrode depends on two important factors namely microstructure and morphology and the effect of doping. These two factors influence the type of cathode materials that can be chosen for the battery. Intercalation and deintercalation happen along particular crystallographic planes and headings, so higher crystallinity enhances terminal
Gaidos begins by using statements made by material scientist George Crabtree of the Argonne national laboratory to acknowledge the accomplishments of the more traditional lithium-ion battery, and explain how new batteries could improve upon them. Lithium-ion batteries did alter individual electronics in an enormous way but they are limited in larger
The EPA estimates Americans purchase nearly 3 billion batteries each year (D., 2009). A battery is also known as a voltaic cell, and the energy generated and stored by a battery is actually a result of chemical reactions and not mechanical motion. Batteries are contained in nearly every common electronic device, ranging from small devices like smartphones to larger scale products like automobiles, and chemistry is the driving force behind the function of these batteries.Batteries consist of galvanic cells that carry out the production and storage of electrical energy from chemical reactions. The chemical reactions going on inside of the battery are between the oxidant and reductant of Copper and Zinc metals in there Copper-Zinc Voltaic
The author states that fuel cell engines have several advantages over internal combustion engines and will replace them and provides three reasons. In contrast, the professor states that the reading argument is optimistic about the fuel cell engine and it won't replace the internal comustion engines and she opposes each of the author's reasons.
Kirsch’s main argument in the article is that there are no better storage batteries for the electric vehicle despite smaller technological changes or improvements that have relatively enhanced the capability of these vehicles. The expectations for better storage batteries were not realized though the electric vehicle was
Rechargeable battery evolution accelerated as the world transitioned to instruments enabled by silicon microchip technology from those of bulky electrical components.

Researchers are charged up about biobatteries, contrivances able to harness prevalent biological processes to engender electricity. Most biobatteries are unable to engender sizably voluminous amounts of potency, but researchers recently developed a prototype version that has the potential to be lighter and more potent than the batteries typically found in today's portable electronic contrivances, including smartphones.
From Tesla’s gigafactory for batteries to new battery technologies every day, this field is ever expanding with inventions and opportunities. Batteries seem like one of the most important paths to the future and I would love to be on the cutting edge of energy
Lithium-ion batteries are becoming more common in portable electronic devices due to their high-energy density, lack of memory effect, and high charge and discharge rate capabilities. Research and development work is ongoing to improve safety and increase capacity, charge/discharge rate, and lifetime. Demand for electric vehicle batteries is currently small, but it is expected to grow very quickly. China, Japan, South Korea, France, and the United States are the major lithium-ion battery manufacturers for hybrid and electric vehicle applications.

Electrical vehicles technology has been present for a while and is a proven technology that need only reshaping to meet the global need. Though, in the past, the technology had failed to compete with the internal combustion engine due to initial cost, the technology has done well in the past few years. Electric vehicle ability to reduce the emission of greenhouse gases like carbon and carbon dioxide and the advantages it enjoys such as low maintenance and running cost can enhance it market competitiveness. However, as experts try to make its charging system more efficient and its ability to store charge more long lasting, the global need continue to rise. The research proposal, therefore, aim at addressing an issue like government involvement can enhance improved use of EV, development of better EV batteries, energy management system and fast charging can help enhance the use of Electrical Vehicles and how electric vehicle drive train and the battery can be redesigned to make it affordable.
Electric cars are becoming very popular in today’s world and are becoming more main stream. One reason for this is the need for automobiles that have a lower or a zero carbon footprint. For the majority of the history of the automobile, the propulsion system was a gas or a diesel engine that would run off of fossil fuels. The burning of fossil fuels is very hazardous to our world and also creates much toxic pollution. However, electric cars run off of electricity, which is a very clean and pollution free resource, depending on how the electricity was produced of course. In this paper we are going to examine the history of electric cars, look into modern electric car technology, and peer into the future of electric car technology to see if EVs might be the answer to dramatically reducing our global pollution.
Abstract—In this modern era, many advancements in technology have been witnessed. Research and data collected around the world have allowed for these advancements to take place. This has allowed for a better understanding of the footprint humans leave on the environment. As a result, this has allowed for the planet to become eco-friendlier. An eco-friendly advancement in the 21st century is the electric vehicle. There are a plethora of benefits using electric vehicles. Some advantages include no emissions, cost-effective, and low maintenance.
Technology has been advancing since the turn of the century at an unparalleled pace with the constant announcement of new gadgets and innovations. Of the thousands of new technological advancements made in the past decade, the introduction of the electric car has been the most widely discussed topic. Electric cars are one hundred percent emission free and can replace the fire spitting, bone chilling sounds of a thunderous gasoline engine with the eloquent silence of luxury and speed. However, as with all things technological, electric vehicles have their problems. Electric cars have several benefits and could possibly replace gas cars in the future, but they are not refined enough to take over the world today because of a few technicalities
One of the first examples of a pyramid built in ancient Egypt was the Pyramid of Djoser. It’s the oldest of the 130 pyramids in Egypt. It is what you would call a step pyramid. The Pyramid of Djoser was built around 4650 years ago or 2640 BC. The pyramid was built in Saqqara, which was a part of the Old Kingdom’s capital, Memphis.
