The future of lithium batteries

From a small point of view, lithium batteries provide the possibility to facilitate and enrich life. In the long run, the use of sustainable energy sources such as wind power, hydropower, and solar energy is the trend in the future. Lithium batteries can be used as energy storage devices to preserve these energy sources. Use when needed to make the power generation device "decentralized".

In addition, as the car gradually began to "electrical", lithium batteries have become the "darling" of the automotive industry.

The use characteristics of car-mounted lithium-ion batteries are different from those of electronic products, such as mobile phones and computers. The design of lithium-ion batteries is "fast charging to meet daily use, and long-term performance does not need to be overly considered." However, electric vehicles require "constant performance over multiple cycles, large power, and fast charging". The conditions are more stringent. Among them, their importance is arranged in order. Cycle durability is the most important, high power and fast charging. It's almost an order of magnitude.

Therefore, for electric vehicles, the high requirements for their lithium-ion batteries have made various manufacturers continue to try new materials or new formulas to meet market demand.

At present, there are only two schemes that are used more frequently, NCA811 (nickel-cobalt-aluminum lithium battery, the number represents the ratio) and NCM811 (nickel-cobalt-manganese lithium battery). However, due to patent reasons and other factors, NCA is only adopted by Tesla, while NCM It is the scheme adopted by most manufacturers. Both have their pros and cons. NCA has higher energy density, but NCM is safer.

With the increasing popularity of electric vehicles in the future, lithium battery technology may become a key part of the "reshuffle" of major car companies. With the trend of global sustainable development, lithium batteries may be as important as petroleum.
