Thanks to the development of new energy vehicles, power batteries are in the wind of high-speed development, and the development of new energy vehicles has also put forward higher requirements for the performance of power batteries The Action Plan for the Development of the Automobile Power Battery Industry is proposed in the "Action Plan for the Development of the Automobile Power Battery Industry".

Lithium-ion battery cycle lifeBatteries are used, feel not durable, capacity is not more than before, these are the continuous decay of the cycle lifeThe decay of the cycle life is actually a changing trend of the actual available capacity of the battery, relative to its rated capacity at the time of delivery.

The primary solution to BMS is security issues and needs to have:1) Overcharge protection, that is, when charging, it must be terminated in time when the voltage exceeds2) Overdischarge protection, that is, termination of discharge when any single unit voltage in the group is below the over-discharge threshold.

Kidman Resources and the Chilean chemical conglomerate SQM have pledged to build a lithium treatment facility in Kwinana, the latest in a series of Western Australian initiatives to challenge China's dominance in the fieldThe companies have been assessing the establishment of the facility, which has an initial capacity of 44,000 tons of lithium hydroxide or 37,000 tons of lithium carbonate per year at the plants in Kwinana, Bunbury and Kalgoorlie.

At present, it is generally believed in the industry that the near-term goal of lithium battery technology is to achieve 300wh/kg through high nickel ternary positive pole and silicon carbon negative pole Medium term (2025) target is to achieve 400wh/kg monomer based on lithium-manganese rich/high-capacity si-c negative electrode; In the future, lithium sulfur and lithium empty batteries will be developed to achieve the monomer specific energy of 500wh/kg.

The South Australia-based manufacturing company Redarctronic expanded the DC-to-DC car battery charger series by adding two lithium iron phosphate(LFP) devices designed specifically for charging 24vLiFeP040 batteries"We now offer two DC to DC chargers for lithium-ion batteries, using chemically specific battery charging algorithms to ensure that they are properly charged to optimal levels," Redarc said in a statement.

I introduction to the structure and properties of grapheneResearchers from the European flagship graphene research project recently explained how a suspension of graphene oxide suspended in water is biodegradable under the catalysis of a human enzyme, and how much of this degradation is related to the colloidal stability of the suspension.

In the past month, Ningde era, Lishen, Zhongtian Storage Energy, and Kelu have all won orders in the power grid storage market, which has opened a new world for lithium iron phosphate batteriesThe Gaogong Li-electric survey found that in conjunction with the national power reform and the power grid group's efforts to ease its own power supply pressure, the demand for power grid energy storage projects based on the transformer's side energy storage and the user side energy storage of industrial and commercial terminals has increased.

The development of battery manufacturing industry has entered the era of labor-intensive, capital-intensive, knowledge-intensive and technology-intensive enterprises The emergence of all kinds of new battery products, the improvement of product manufacturing complexity, the application of high-precision equipment, the battery industryWith the rapid development of electric vehicles and the car, the car with the power source and the rapid development, but the battery has a lot of problems in production, caused the market's battery product quality is uneven, the capacity of the battery cycle life can not meet the design service life of the late, this in battery in production has its unique production process has a lot to do.

Lithium battery overdischarge protection, with constant current constant voltage source directly charge the cell (lithium battery removed after the protection plate a lithium cell); In don't open the battery case, trying to tear the label paper, a small mouth, tore open the outer packing should be an aluminum shell, with constant current source of black pens and toward the anode input end of the protection board, red pens and to the aluminum shell charging, charging voltage to 30 V above can stop, lithium battery protection board at this time of protection natural cancelled; Cover the exposed aluminum shell with tape; Then you can directly charge the battery with the charger, but also pay attention to whether the battery drum, if there is, the battery still can not be used; If the above method still fails to charge the battery, then the battery must be disassembled and charged directly to the positive and negative poles of the cell.
