According to Bloomberg News, Tesla CEO Elon Musk said in a conference call that Tesla has mastered technology to reduce amount of cobalt metal in lithium-ion batteries The original quote: We think we can get cobalt to almost nothing.

Advantages:Energy ratio is high With high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times of lead-acid battery.

Battery China Network collects data of new energy vehicles in the first quarter of 2018, and analyzes top 10 automakers in production of new energy passenger cars, buses and special vehicles, in an effort to find development trend of new energy vehicles in the futureIn the first quarter of 2018, the total output of new energy vehicles was 141,069, of which passenger car production was 128,912, accounting for 91%; passenger car output was 6,935, accounting for 5%; special vehicle production was 5222, accounting for 4%.

Ternary materialTernary polymer lithium battery refers to a lithium battery using a lithium nickel cobalt manganese ternary positive electrode material for the positive electrode material There are many kinds of positive electrode materials for lithium ion battery, mainly including lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate and so on.

Recently, the Ministry of Finance, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the National Development and Reform Commission jointly issued the “Notice on Adjusting and Improving the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles” The new subsidies have increased thresholds of the energy density of the power battery system for non-fast-charged pure electric buses and special vehicles, speeding up the elimination of low energy density batteries.

Lead-acid batteries are safe, durable and more affordable for civilian use There are many kinds of lead-acid batteries.

Lithium-ion battery protection board is charge and discharge protection for series lithium-ion battery pack; when fully charged, it can ensure voltage difference between each unit battery is less than set value (generally ±20mV), and achieve equalization of each unit of battery pack and effectively improving charging effect under series charging mode Also simultaneously detect overvoltage, under voltage, overcurrent, short circuit, and over temperature conditions of each single cell in the battery pack, protect and extend battery life.

Lithium ion battery has the advantages of high energy, long cycle times and high efficiency and is widely used in various electronic products For example, our common battery charger is composed of 18,650 lithium ion batteries.

Yesterday, the news from a professor at Hunan University who developed an aluminum-ion battery appeared in major media In the report, the professor of Hunan University published a paper in a famous scientific journal, and developed an aluminum-ion battery with fast charging and long cycle life, which will change the world.

Why is the battery the heart of an electric car? This must start with the history of electric vehicles When it comes to electric new energy vehicles, it is easy to classify them into a whole new technology and things.
