Following the introduction of the concept of carbon neutrality, the combination of clean energy and lithium battery has become a certain path toward green development. But there are three major pain points facing lithium recycling. First, worldwide, the proportion of lithium batteries reused is extremely low, estimated to be less than 10%. Second, the waste lithium batteries contain high-value elements such as lithium, cobalt, nickel and copper. While, China imports a lot of lithium, cobalt, and nickel every year, so lithium battery recycling is a good solution to the resource and environmental problems. Third, the current recycling process adopted in the industry costs more than the production of batteries, and the yield rate is low, but the recycling market for lithium batteries is huge.

Year by year, driving up the demand for AEDs, but AEDs are still rare to find in China. Deeply concerned with this, the government has issued several documents to expand the coverage of AEDs. Compared with the developed countries, we can see that the AED penetration rate in China is low, making it a niche market with promising prospects. We conducted a survey on existing products in the market, evaluated them in two dimensions: the prediction and the AED portability, and found that no products excelled in both indicators. Therefore we hope our product can make real-time prediction and carry a portal AED, capable of achieving multi-party linkage and, if necessary, providing emergency rescue with AED to save lives.

The digital human related industries have three pain points: slow calculation speed, poor results and high cost, which have greatly hindered the commercialization of digital human technologies and products. In response, the biggest goal of the insiders is to develop low-cost universal human digitization technology with high-fidelity and credible digital human reproduction technology, create an immersive human-computer interaction experience, promote the digitization of traditional industries, and achieve sustainable development. As an important part of digital human technology, our speech-driven facial expression generation solution can solve these three problems to a great extent.
