Lithium-ion battery patents exposed, Huawei may launch ultra-high-speed charging technology?

As we all know, battery life is the sword of Damocles hanging over smartphones. Among the many features of smartphones that provide a high-quality user experience, the length of battery life is one of the weakest links. Cell phone manufacturers have been addressing this issue in two main ways: either by adding fast charging capabilities; or by increasing battery charging density.

The State Intellectual Property Office of China recently published a patent for a lithium battery invention by Huawei, which describes a new anode active material for lithium-ion secondary batteries, which happens to be a combination of the above two options. Huawei introduced a high-energy density silicon-based material system in the battery material, and through the innovative technology of heteroatom-doped silicon-based material, it provides a fast channel for the migration of lithium ions during the charging process, and significantly battery fast charging capability.

According to industry experts, Huawei’s choice of silicon material in lithium-ion batteries is significant because its embedded lithium capacity is much higher than the traditional graphite anode. This means that it can lock more energy, thereby increasing the energy density of lithium-ion batteries.

The nitrogen-doped carbon material can be used to bind the silicon material of lithium-embedded expansion, nitrogen atoms and carbon atoms in the form of pyridyl nitrogen, graphitic nitrogen and pyrrole nitrogen combined to form a stable three-dimensional carbon skeleton network to inhibit high-capacity silicon materials; in addition, nitrogen-doped carbon network can improve the overall electrical conductivity of the composite material containing silicon material / nitrogen-doped carbon material, new physical fast lithium storage space and channel, breaking the limit of chemical lithium storage In addition, it can significantly increase the limit value of the battery charging current.

If this assumption is true, then this patented technology is likely to be a new iteration of the Honor Magic battery. It is also an improved version of the ultra-high-speed charging technology that Huawei showcased at the 56th Battery Symposium in Nagoya, Japan. Just as multi-touch technology has changed the shape of cell phones, Huawei’s ultra-high-speed charging technology will redefine the way people use smartphones and save users from “cell phone power anxiety”.

It is worth mentioning that Huawei’s ultra-high-speed charging technology is also used outside of consumer electronics. For example, it can drive electric cars in the form of battery packs. So will Huawei expand its business further in the future? Huawei has not yet responded to this, but we can see from the technology that although the battery is expensive to develop, it will also bring higher returns in the future.
