New energy vehicle graphene "super energy" battery breaks through the technical bottleneck

Ultra-thin ultralight aircraft, ultra-thin foldable mobile phones, space elevators.

Known as the "miracle material of the 21st century", graphene carries countless imaginations
with its magical properties.
Major countries in the world attach great importance to the development of graphene-related industries and expect it to bring huge market value
.
A "super energy" battery with graphene can be charged to the maximum capacity in 30 minutes, equipped with a cruising range of up to 400 kilometers on new energy vehicles, and the weight of the battery is greatly reduced
.

After adding graphene to the cell, the battery can run 400 kilometers in one hour of charging

At present, the charging technology of new energy vehicles generally cannot meet the requirements of fast charging, and batteries have become a bottleneck
in the development of new energy vehicles.
"The fast-charging lithium battery we developed this time can shorten the charging time to half an hour
.
" Gao Hongsen, deputy general manager of Yuhuang Company, said

Compared with traditional power batteries, this fast-charging battery has an energy density of 135Wh/kg, nearly 40 Wh/kg higher than other brands on the market, and the weight is greatly reduced
.
Compared with ordinary household new energy cars, the weight of this new battery is less than half of the traditional rechargeable battery, charging time, 10 minutes to charge to 80% of the maximum capacity, 30 minutes can be charged to the maximum capacity, normal use of the number of charging times can reach more than 3000 times, several times the current charging battery life in various equipment, and the cruising range can reach up to 350-400 kilometers
.

Gao Hunsen said that the improvement of product performance comes from the improvement of the performance of basic raw materials, and the biggest feature of this fast-charging lithium battery is the addition of graphene
.
As a new nanomaterial with the thinnest and strongest electrical and thermal conductivity found so far, graphene is added to the battery cell to reduce the internal resistance of the battery cell to a minimum, effectively solving the technical bottleneck that hinders the fast charging of lithium battery products, and greatly extending the battery life
.

With the unremitting efforts of the R&D team members, in the first half of 2015, the new lithium battery products were finally finalized
.
Subsequently, Shandong Yuhuang New Energy Technology Co.
, Ltd.
built the first new battery production line, which has been put into production, focusing on the logistics vehicle and sightseeing car market
.

Although this battery has not been officially put on the market, informed manufacturers have begun to continue to come to the door to ask for goods
.
Supporting this, the company's newly built graphene production line can be put into production at the end of this year, which can achieve a production capacity of 3 tons per year, providing a strong raw material guarantee
for the production of batteries.
"It will take a process to officially launch on the market, and I believe it can be achieved
in the next year or two.
" For the future development of this new lithium battery, Gao Hun Sen is full of confidence
