Why does lithium battery charge more temperature than discharge

The battery products of many companies can achieve normal discharge at low temperature, but at the same temperature, it is difficult to achieve normal charging, or even unable to charge. When Li+ is embedded in graphite material, it must first be solvated. This process will consume a certain amount of energy. Li+ is hindered from diffusing into the interior of graphite; on the contrary, Li+ will have a solvation process when the graphite material is released into the solution, and solvation does not consume energy, and Li+ can quickly come out of graphite. Therefore, the charge acceptance of graphite materials is significantly inferior to the discharge acceptance.

Innovation drives the sustainable development of the new energy industry. Guanjia Lithium Battery keeps its mission in mind and sticks to its original intention

Under the electrification transformation of the global energy industry, the rapid development of the lithium battery industry has set off a global storm of lithium batteries. Statistics show that the global lithium battery market segments have maintained rapid growth. For example, the shipment of lithium batteries for light vehicles will reach 9.7GWh in 2020, a year-on-year increase of 78%; 124%. China's lithium battery companies have ushered in an opportunity for comprehensive development. But at the same time, the lithium battery industry is characterized by capital-intensive, talent-intensive, technology-intensive, and high-quality risks, which is an industry threshold that is difficult to cross. On the other side of opportunities are challenges and risks: investment encirclement and blind expansion lead to overcapacity structure; attack from all sides while ignoring business management and deep cultivation of market segments; blindly pursuing a single data indicator, ignoring comprehensive technical requirements; ignoring quality , quickly gain the market with low-price competition, and seek short-term benefits. All of these may become hidden reefs under the changing situation of the industry.

The electric bicycle market may become a new battlefield for lithium battery companies

Due to the huge stock of lead-acid batteries, the market prospect of "lead-to-lithium" in the field of electric bicycles is attractive, but the road to replacement is not smooth. Lithium battery companies that come from across the border want to profit from the electric bicycle market. It is difficult to imagine, and they are facing challenges in terms of cost, channels, and product standards.

What are the recycling channels for power lithium batteries?

The life cycle of a power battery includes production, use, scrapping, decomposition and reuse. After the power battery is scrapped, except for the decline in chemical activity, the chemical composition inside the battery has not changed, but its charge and discharge performance cannot meet the power demand of the vehicle, but it can be used in places with lower power requirements than automobiles. The cascade utilization of power batteries has therefore become one of the most discussed recycling methods in the industry. The batteries that are about to be used in automobiles will be used in energy storage or related power supply base stations, street lights, and low-speed electric vehicles after they are eliminated, and then enter recycling. system, but this business model also faces the consideration of whether it can be profitable, involving channels and technology issues.

Why is the power battery market strong?

According to the China Association of Automobile Manufacturers, from January to May 2017, the production and sales of new energy vehicles were 147,000 and 136,000, an increase of 11.7% and 7.8% year-on-year. Among them, the production and sales of pure electric vehicles were 122,000 and 111,000, a year-on-year increase of 22.8% and 20.7%. In the lithium battery market, the power battery has increased from 43% in 2016 to 55% in the first half of 2017, and the market prospect has been rising all the way.
