The innovation of lithium battery technology provides opportunities for the development of civilian electric equipment. Traditional lead-acid batteries are being gradually replaced. Lithium batteries, as the current main electric energy source, are rapidly entering our lives. Topbond Battery as a professional lithium battery manufacturer in China, will tell you about lithium batteries and lead-acid today. The difference in battery!

Main ingredients

The main components of lead-acid batteries are lead and acid. During use, a large amount of heavy metal lead and acid mixture will be produced. Improper storage will cause environmental pollution. The main components of lithium batteries are lithium and some other light metals. From the perspective of environmental protection, lithium batteries are better.

Energy density

The energy density of lithium batteries is about 160WH/KG, and the energy density of lead-acid batteries is only 40WH/KG. If the battery compartment of the lead-acid battery of an electric tricycle is filled with lithium batteries, the cruising range will be doubled, and the weight is only 2/3 of the lead-acid battery.

Life comparison

There is no doubt about the power and battery life of lithium batteries. Anyone who has used lead-acid batteries knows that the capacity of lead-acid batteries will be reduced by about half after one year of use, and the power and battery life will be greatly reduced. The average life of lithium batteries is about three years, which is more durable.

Price difference

The most important thing is that lithium batteries not only have good performance, but also the price is king. Taking a certain brand of 72V20AH battery as an example, the prices of lithium batteries and lead-acid batteries are 1968 yuan and 1238 yuan respectively. The average cost of lithium batteries is 656 yuan/year, while the average cost of lead-acid batteries is 1238 yuan/year.

Although the one-time investment cost of lithium batteries is much higher than the cost of lead-acid batteries, in general, it goes without saying that everyone understands.

Safety performance

But no one is perfect, and nothing is perfect. The higher the energy density of the lithium battery, the lower the stability.

With the development of the lithium battery industry, different brands of lithium battery technology and quality are uneven. Some inferior lithium batteries are prone to fire or even explode in high temperature environments. Therefore, when choosing lithium battery products, you must choose a regular manufacturer, because safety is the foundation. On February 26, local time on Thursday, electric car maker Tesla CEO Elon Musk (Elon Musk) tweeted on his personal social media Twitter that the company will replace the ternary lithium batteries of some electric vehicles with iron. lithium battery. "Nickel is our biggest concern in lithium battery production," Musk tweeted. "That's why we're replacing standard-range EVs with iron-lithium batteries. Iron-rich lithium batteries!"

Musk has previously asked miners to produce more nickel. But metals analyst Allan Ray Restauro (Allan Ray Restauro) said nickel supply will continue to be grim for the next three years. With rising demand, there could be a severe nickel supply shortage as early as 2023.

Nickel is a key component in the production of ternary lithium-ion batteries for electric vehicles, which makes the battery more energy-dense and allows for a reduction in the amount of cobalt used in the battery. Since cobalt is more expensive, the supply chain is more opaque.
