No matter how many generations of smartphones have been launched, we face the old question of how long the battery life is the same No matter how much optimization the vendor makes, it's ultimately just an hourly difference.

In 2016, the relevant policy departments issued an important regulatory document for the size of the power battery This is the "Size of Power Battery Products for Electric Vehicles"(draft for comment), which was released in October 2016.

Smartphone batteries have become the biggest pain point for users, and mobile phone manufacturers are looking for ways to alleviate the lack of battery life, but with little success As a user, while we hope that R&D institutions will solve this problem as soon as possible, we must also pay attention to some methods for charging and using mobile phones, so as not to make the already stretched mobile phone life ability even worse.

On May 9-10, 2018, the GB/T drafting meeting on functional safety requirements and test methods for battery management systems for electric vehicles was successfully held in Ningde Times New Energy Technology Co, Ltd.

 Professor Yang quanhong of the Institute of Chemical Engineering of Tianjin University and his research team finally completed the "tailor" of graphene wrapped in active particles through the design of high-volume energy density lithium ion battery negative electrode materials, making lithium ion batteries "smaller" Become possible.

On May 11, Corun announced that it would increase its registered capital by 2176 million yen (about 12.

Chuanfu Wang once said that it was easy to make Tesla Now that both Beiqi and BYD have broken through 400 kilometers in terms of cruising range, from the perspective of batteries and power systems, is the domestic electric vehicle really only a little distance from Tesla? Both BYD and BAIC have already exceeded the 400km mark on their cruising range.

Dry batteries are one of the most widely used products in our daily life From cameras, tape recorders, calculators and electronic alarm clocks to pagers, electronic dictionaries and PDAs, we are inseparable from dry batteries.

Nickel-metal hydride batteries are known as the most environmentally friendly batteries because of the low levels of environmental pollution Compared with lithium batteries, nickel-metal hydride batteries have higher memory effects and higher self-discharge rates.

First, China's hydrogen fuel cell vehicle industry related policies In October 2016, the “Blue Book of China Hydrogen Energy Industry Infrastructure Development (2016)” issued by the Resource and Environment Branch of China National Institute of Standardization and China Electrical Equipment Industry Association first proposed the development roadmap of China's hydrogen energy industry The development goals of medium and long-term hydrogen refueling stations and fuel cell vehicles in China have been planned.
