Elon Musk was wrong for a couple of years: deliveries of batteries with a record energy density of 450 W h / kg began
The US company Amprius announced the start of deliveries of the first commercial lithium-ion battery cells with an energy density of 450 Wh/kg, which are lithium batteries with the highest energy density currently available.
On November 8, 2021, the company announced the mass production of a battery with a density of 405 Wh/kg, and in just a few months, the density increased to 450 Wh/kg. To achieve this result, an Amprius silicon anode (Si-Nanowire platform) is used.
Interestingly, Tesla CEO Musk stated in 2020 that a battery cell with an energy density of 400 Wh/kg will be available by 2023-2024 and will significantly reduce the mass of the battery. That is, Amprius managed to significantly outperform Musk’s forecasts.
Currently, Tesla Model 3 electric vehicles are equipped with a battery with an energy density of up to 260 Wh/kg. At the same time, the latest battery has a 73% higher energy density, while the volume is reduced by 37%.
Amprius has a very close relationship with Tesla and is located next to Tesla’s battery plant. In the future, the possibility of in-depth cooperation between them is not ruled out. After installing such a battery in electric vehicles, the cruising range can reach 1000 kilometers.

DJI is preparing a new “racing drone” Avata with a quality camera at the level of Mini 3 Pro

DJI recently introduced the Mini 3 Pro compact drone, and soon another compact FPV class model (the so-called “racing drone”) will appear in the company’s range. The source says what is called the new Avata.
Visually Avata is very different from DJI FPV. We can say that conceptually these are completely different models. Avata’s outdoor design makes it more suitable for indoor use.
Together with a radically redesigned design, significantly improved photo and video quality is also promised: it is expected to be at the level of the Mini 3 Pro. The third important feature is improved autonomy. The weight of the novelty will be about 500 grams, along with it, DJI is likely to introduce a new system for controlling the FPV drone. The premiere of Avata is expected in the summer.

Xiaomi has published a teaser image dedicated to the RedmiBook Pro Ryzen Edition 2022 laptop. Its premiere is expected very soon – May 24th. The image gives an idea of the display parameters of the novelty.
The laptop will receive an IPS panel with a diagonal of 15.6 inches, a resolution of 3.2K and a frame rate of 90 Hz. The maximum brightness will be 400 cd / sq.m, the DeltaE value will be less than 1.5 units. The display will cover 100% of the sRGB color space.
Nothing more has been officially said, but the source believes that the laptop will use an 8-core AMD Ryzen 7 6800H APU with 16MB L3 cache and a frequency of up to 4.7GHz. There will be no discrete 3D accelerator. The RedmiBook Pro Ryzen Edition 2022 also has a backlit keyboard, stereo speakers, and a 72 Wh battery.
