Known as the "king of new materials" by researchers and media, graphene is a new type of nanomaterial with high strength, good toughness, light weight, high light transmittance and good electrical conductivityGraphene polymer batteries, which shine in all their brilliance, have advantages such as higher energy ratio and faster charging rate, which are exactly the pain points of today's electric cars.

As nokia Lumia920, Google Nexus4, samsung S6 and other models have added wireless charging function, this year's apple's annual flagship phone iPhoneX also added wireless charging function, so wireless charging is good? Here for you to bring the advantages and disadvantages of mobile phone wireless charging analysis, a lookPrinciple of wireless chargingThe concept of "wireless charging" sounds pretty cool, and it seems to have the same impact as mobile phones replacing fixed lines, digital instead of film, and WiFi instead of cable.

Power battery is the power source that provides power for tools It mostly refers to the battery that provides power for electric cars, electric trains, electric bicycles and golf carts.

China has become the world's largest producer of lithium-ion batteries, matching South Korea and Japan in the global market China's power battery production capacity has reached 38 kilowatt-hours, accounting for 60 percent of global capacity, according to a report released last week at the China (qinghai) lithium industry and power battery international BBS conference in xining, capital of northwest China's qinghai province.

E-bike lithium battery can be used for a long distance, there is no pollution problem to the environment, renewable, in line with the concept of sustainable development1, storage requirements: the temperature is 25 + / - 5 ℃, humidity is no more than 50% of the environment, transport to avoid air and water vapor on the aluminum foil erosion;2.

In recent years, as the production and sales of new energy vehicles in China have entered a blowout period, problems such as fraudulent subsidies and automobile safety have also begun to be exposed How can we promote the steady development of new energy industry? This not only requires more scientific and strict market access rules, but also introduces "catfish" like tesla to the industry.

South Korean scientists have made a breakthrough in research and development of car batteries Siliconoxidenanopowder, a newly developed cathode material for lithium-ion batteries, can more than double the mileage of an electric car in a single charge.

At present, people use mobile phones, the energy density is generally in the 560-580wh /L range, and the battery capacity is limited to 2500-3000mah or so, that is to say, the charging frequency to reach a charge or two a day, whether your mobile phone is an iphone or huawei, xiaomi charging common skills, to save every lithium ion batteryFifty percent is a trap.

The battery capacity of a new energy pure electric vehicle usually measured in kilowatt-hours (kWh).

"Now the mobile phones are all lithium-ion batteries Do we still need to charge new battery for 12 hours on the beginning?" The public is generally unaware of this problem.
