Nowadays, the power issue in the electric vehicle market has become a focus of attention, and the battery, which is closely related to power, must become the focus. So the question is: which battery has the best performance, lithium iron phosphate battery, ternary lithium battery, or hydrogen fuel cell? What are the future trends? Today, we will compare three new energy batteries to address this issue. Who will receive the ultimate favor?
Lithium iron phosphate battery, as the name suggests, is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material. In the early days, due to material limitations, many manufacturers would find ways to save costs. Lithium iron phosphate batteries are favored by manufacturers for their stability, safety, and low cost. Manufacturers all want to reduce the cost of batteries while ensuring a guaranteed range. So, with the advancement of technology, ternary lithium batteries have emerged. Why was lithium iron phosphate eliminated? It's just high energy consumption and low density. In the same range, this battery has a higher weight, which may result in suboptimal energy consumption. Therefore, some experts once predicted that the development of lithium iron phosphate batteries has reached a bottleneck period, and the replacement of lithium iron phosphate batteries with ternary lithium batteries will be the historical trend in the development of new energy vehicle power batteries.
Survival of the fittest is already a trend in social development. Three element lithium batteries have high energy density and low price, which naturally becomes the choice of manufacturers. Who wouldn't want to reduce costs while ensuring power? In addition, the "Development Plan for Energy Conservation and New Energy Vehicle Industry (2012-2020)" clearly states that the energy density requirement for battery modules is greater than 150 watt hours/kilogram. From this perspective, lithium iron phosphate batteries cannot compete with it. But is this battery really perfect? The answer is negative.
Ternary lithium batteries will decompose at around 200 degrees Celsius, and the electrolyte will rapidly burn. If it is in a "furnace city" with high temperatures and enclosed environments, there is a greater risk of spontaneous combustion and explosion. In addition, if not properly recycled, the positive electrode material in lithium batteries can cause heavy metal pollution. However, in the Chinese market, this battery is still mainstream. Both disposable lithium batteries and secondary lithium batteries contain various metals and organic solvents such as electrolytes. Electrolytes have significant corrosiveness and chemical toxicity. If the battery explodes and burns, it will also produce toxic chemical gases, causing pollution to the environment.
With the shortage of energy resources, the country has begun to frequently implement favorable policies for macroeconomic regulation, hoping to replace lithium batteries with clean energy with less pollution and lower cost. Hydrogen fuel cells are pollution-free, have a long service life, and emit no pollutants, making them very environmentally friendly. Uncle Che is about to start today's physics class again: the basic principle of this battery is the reverse reaction of electrolyzing water. It doesn't need to be charged, only hydrogen gas needs to be added, making it easy to use. With this battery, we no longer have to go to great lengths for charging. Car owners no longer need to spend a lot of time charging, they just need to add some hydrogen gas, which is as convenient as refueling now. Therefore, the industry also believes that this battery is known as the "ultimate new energy power solution".
