Huawei’s lithium-ion battery conductive binder patent passed
According to the latest information, a new patent related to Huawei’s lithium battery was passed and was published by the State Intellectual Property Office. The name of the patent is “a conductive binder for lithium-ion batteries. According to the description, this patent uses polyvinyl alcohol, polyethylene glycol, polystyrene, starch, sodium alginate, etc.
As per the data, the value of graphene is 0.1%~10% of the total mass, the thickness of graphene particles is 5nm~50nm, and the D50 particle size is 50nm~5000nm. This invention uses two adhesives, the first adhesive accounts for 20%-50%, and the second adhesive uses materials such as polyacrylic acid and polyimide, which are combined with the first adhesive through chemical bonds.
The patent details that it has as a silicon particle, 2nd is graphene, and 3rd is a binder. Silicon particles are confined in this hollow structure, even if they expand, they will not lose performance.
According to the patent description, in order to increase the energy density of current lithium batteries, graphite anode materials are often replaced with alloy materials such as silicon.
After 50 cycles of the two-button prototype batteries made by this patent, the capacity retention rate is over 90%, and the discharge efficiency is as high as 97% and 98%, which means the battery’s internal resistance is still very small and there is no loss.

Huawei Sound X4 smart speaker was launched on Huawei Mall, and full pre-sale started on the same day, and the first sale of the new product started at 20:00 on October 31.
The smart speaker is available in two colors: Rhythmic Black and Dynamic White, priced at 2199 yuan and 2599 yuan respectively.
The speaker contains eight units, including 1 woofer, 4 mid-range speakers, 1 tweeter and 2 passive radiators . Officials said that the high, medium and low frequency units work within their respective frequency response ranges, giving full play to the advantages of each unit. A HUAWEI Sound X4 can bring “symphony orchestra-like” sound effects.
The speaker has obtained Hi-Res high-definition sound quality certification, which can provide more sound details and also perceive the spatial sense of the sound. Its subwoofer has a power of 50W and is also equipped with 2 passive radiators. The low frequency dives to 36Hz and has a 25mm stroke.
In addition, its high-frequency unit has a power of 3W and the mid-frequency unit has a power of 5W, and they use pure titanium diaphragm and self-developed mica fiber diaphragm respectively.
The speaker is equipped with Huawei SOUND bass enhancement algorithm, which can actively control the vibration of the speaker, reduce distortion, improve the transient response of low frequency, and achieve deep and powerful low frequency performance. It adopts Sym-Pole mirror design to offset vibration noise and bring rich bass.
In addition, it supports control methods such as one-touch, one-cover, and two-tap, which can respectively complete operations such as lighting, muting, and turning off the lights. The speaker also supports intelligent recognition of spatial structure, emitting sound waves to detect the room structure and receiving feedback, and can automatically match the sound effect scheme in the spatial scene.
Huawei’s GoPaint App was released in May this year and officially launched in August this year. The App is a digital painting software provided by Huawei. Yesterday, the app was newly adapted to 4 tablets including the MatePad Pro 11-inch 2022 model.
A user recently asked in the community for the app compatibility and support replied that “This function is expected to be supported in the first quarter of 2025.”
According to reports, the official version of GoPaint App has over 150 preset brushes, more than 80 brush parameters that can be adjusted, and fluid brushes that can restore the real pen-and-paper rendering effect. At the same time, new realistic canvas styles have been added, including watercolor, ink, oil painting, rock color, etc.
The official version of GoPaint App also has Fangtian Painting Engine 2.0 built in, supports 100+ 6K high-definition layers and 8K ultra-large canvas, and is the first to use a floating splash brush, which can splash ink by double-clicking the pen.
Huawei has now started rolling out the September 2024 security patch update to the Pura 70 lineup in Europe.
