(August 2) Tesla Motors rose nearly 5% in morning trading.
Elon Musk confirms Tesla AI Day will be on August 19.
In addition ,Last Thursday, Benzinga Proalerted its users Tesla hadfiled a patentthat would allow it to recover and recycle nickel and cobalt from old lithium-ion EV batteries.
The patent, titled “Metal Sulfate Manufacturing System via Electrochemical Dissolution,” would allow the EV and technology company to recover the two crucial raw battery metals and reuse them making its supply chain more efficient.

性能电池和普通动力电池究竟区别几何？牛瓦时克联合创始人王佳伟给出了自己的观点。“从电芯选择上，性能电池需使用功率密度极高的电芯，而动力电池则使用能量密度高，功率要求低的电芯。”
“自然，考虑到性能电池的高功率输出，势必会产生一些不可回避的挑战。最直接的就是发热，所以我们不仅需在BMS（电池管理系统）上做足文章，还必须使用高导电性的材料。举个我们产品的例子，在我们的‘入门级电动赛事电池组（eRacing Junior Moudle）’产品里，温度传感器的数量约是车规级的五倍以上。另外，适应于性能电池的一般应用环境——赛车运动，我们需对整个电池组的强度进行处理，碳纤维保护外壳是标配。”

What are the differences between everyday ordinary batteries and high-performance batteries? The answer is easy, different target!
Our co-founder Jiawei Wang has his opinions: "High-performance batteries use core cells with extremely high peak and continuous power rating, and ordinary batteries choose high energy density."
"Considering high-performance batteries’ extreme power output, challenges are inevitable. Firstly, as we know, there is a trade-off between the power density and the energy density. It means high-performance batteries normally cost more."
"Secondly, the heat generated means we need to extensively modify the BMS (Battery Management System) and HMD (Heat Management Design) for the safety and efficiency, at the same time use materials with high conductivity. Our eRacing junior module is a good example, the cars have 5 times the number of temperature sensors compared to Road EV. "
"Finally, in the tense environment of motorsport, a strong case ensures the strength."
