Chongqing high-tech zone enterprise research and development of all solid-state lithium battery storage capacity can be increased by 2.5 times

As handheld electronic products become more and more powerful, their performance is getting stronger and stronger, and power consumption is also increasing. However, most of the traditional batteries are not only capable of long-term battery life, but also safety accidents caused by quality problems. In response to various problems of traditional batteries, Chongqing Hanyue Technology Development Co., Ltd., located in Chongqing High-tech Zone, has developed an all-solid lithium battery, which not only greatly improves safety, but also stores more electricity than conventional batteries, and the price is also high. The magnitude is decreasing. With this all-solid-state lithium battery, Hanyue Technology also won the Excellence Award in the National Finals Enterprise Group of the New Energy and Energy Conservation and Environmental Protection Industry in the 5th Innovation and Entrepreneurship Competition.

Full solid lithium battery can be recharged 3000 times

The reporter learned that the existing rechargeable battery provides electrical energy through chemical reaction. If the battery quality is unstable, it will generate excessive chemical gas. When the large current is rapidly charged and discharged, the battery will be forced to explode and even burn. “In short, there is a diaphragm material between the positive and negative electrodes of the battery, and there are many holes for insulation. This part is easy to crystallize after repeated charging, and once the quality is too hard, it may cause an explosion. The all-solid-state lithium battery developed by this company is to replace this part of the diaphragm material from liquid to solid." Ren Yue, chairman of Chongqing Hanyue Technology Development Co., Ltd. said.

Generally speaking, the ordinary battery is divided into a positive electrode + a charge liquid state isolation layer + a negative electrode, and Han Yue Technology converts the rechargeable liquid into a completely self-developed solid electrolytic paper, thereby preventing electrons between the positive and negative electrodes of the battery from colliding with each other.

The all-solid-state lithium battery is not only safer, but also has a longer battery life and longer life than conventional batteries. Ren Yue introduced that the average traditional battery can only be charged about 1000 times, and the capacity is around 1000mAh. The all-solid-state lithium-ion mobile phone battery developed by Hanyue Technology can be recharged up to 3,000 times, with a capacity of about 2400 mAh, and the service life has increased to more than three times. The simplest example is that the battery life of the mobile phone can now be up to 1 day to 1 day and a half, and the full solid lithium battery can be used for 2 days to 2 days and a half.

“Because of the production process of all-solid-state lithium battery, it has the characteristics of high degree of automation and high modularity. It can increase the output of products per unit time during the preparation process, and can greatly reduce labor costs. Secondly, its substrate materials are diversified. According to the different performance requirements, the substrate materials of different cost can be used. In this way, the all-solid lithium battery can reduce the cost more than the traditional lithium battery," he added.

Leverage Dongfeng Chongqing or form a billion-dollar emerging lithium battery market

He told reporters that the all-solid lithium battery is not a single category, can be derived from any form, the thinnest one is only 0.05 mm. It will be used in electric vehicles, mobile phones, cameras, charging treasures and other channels, a variety of products.

“In 2016, the national new energy industry market has maintained a 2 to 3 times increase. The total market demand for power batteries is about 30GWh. As far as the Chongqing market is concerned, three new energy pillar industries have been formed, and the total amount of batteries required will be Up to 30 million kw. If calculated according to 3,000 yuan / kw, after rough statistics, only Chongqing local market can form 100 billion yuan of emerging lithium battery market." Ren Yue said.

According to reports, Hanyue Technology is the only company in the city and even the southwest region to develop all-solid-state lithium batteries. It has won the first prize of Chongqing Science and Technology Little Giant, the second and fifth innovation and entrepreneurship competition in the Southwest New Material Competition. And the outstanding awards of the national finals enterprise group of energy conservation and environmental protection industry. “We are currently negotiating with a number of mobile phone manufacturers and we hope to cooperate with electric vehicle companies in the future.”
