Introduction: Chinese scientists have created a fully printable perovskite solar cell with an efficiency of 11.78% by using electrodes made from waste carbon powder in printer cartridges. The battery achieved an open circuit voltage of 0.88V, a short-circuit current density of 24.64mAcm, and a...

These factors have added difficulty and cost to the cascade utilization of retired power lithium batteries. After Battery recycling are recycled, they should be tested first, then classified according to different sources, specifications and capacities, and finally reorganized and reused....

Battery re employment The power lithium battery of new energy vehicles is mainly Lithium iron phosphate ion battery and ternary lithium ion battery. The former has lower cost, while the latter can bring longer endurance but higher cost. Each has advantages and disadvantages....

New energy vehicles are gradually popularized in China, followed by the issue of retired Battery recycling recovery.In theory, the power lithium battery life of new energy vehicles is generally 8 years or corresponding to a mileage of 120000 kilometers. But in practical use, the battery life is usua...

The recycling and reuse of power lithium batteries is not optimistic. Taking the new energy vehicles with the largest usage in the field of lithium-ion batteries as an example, as of the end of 2020, the total number of new energy vehicles in China reached 4.92 million, accounting for 1.75% of the t...

Secondly, the technological innovation of new energy batteries lags behind. After years of effort, the quality of domestic new energy batteries has undergone tremendous changes, with greatly improved energy density. However, the overall technological innovation strength is weak. Among consumer compl...

2021 is the first year of the "14th Five Year Plan". As the concept of Low-carbon economy is improving, new energy will be used more widely. On December 21, 2020, the State Council Information Office officially announced the white paper of China's Energy Development in the New Er...

The third is the full support of national policies. Since the launch of the "863" plan for electric vehicles in 2001, the "Three Horizontals and Three Verticals" of new energy vehicles, including power lithium batteries, have been announced. The State Council, the National...

The second is the continuous breakthrough in battery innovation. Taking the power lithium battery as an example, as the power lithium battery accounts for up to 30% of the manufacturing cost of new energy vehicles, the depth of its technological innovation determines the market width of new energy v...

Looking back to 2020, it is appropriate to describe the new energy battery market with the four words "extremely extraordinary" proposed by the Central Economic Work Conference. In 2020, affected by the COVID-19, the economy at home and abroad was almost at a standstill, and the new...
