Zhi Chunyi believes that due to the high range requirements of electric vehicles and the high energy density of lithium-ion batteries, they will still have an advantage in this market. But considering factors such as the safety, cost, and lithium metal reserves on Earth of lithium-ion batterie...

Associate Professor Zhi Chunyi from the School of Science and Engineering at City University of Hong Kong said that zinc based batteries (hereinafter referred to as zinc batteries) have a history of over a hundred years and are the second commercially available battery in the world, only sligh...

The raised lithium polymer will affect its use in conjunction with mobile phones or digital cameras, and the presence of additional gas will affect the charging and discharging capacity of the battery between the battery panels. There are strict requirements for lithium-ion battery chargers, w...

Is it feasible to recycle polymer lithium-ion batteries? One is that a large number of polymer lithium-ion batteries will reach their retirement period in the coming years. It is expected that in 2015, the cumulative scrap of polymer lithium-ion batteries will be around 20000 to 40000 tons. By...

At the same time, major companies are constantly upgrading the safety of ternary lithium-ion batteries, including overcharging protection, over discharge protection, over temperature protection, etc. With more and more upgrades, the safety of ternary lithium-ion batteries has been greatly impr...

High security The most important feature of this type of battery is that it has a high density of energy and high voltage, which leads to the use of battery packs of the same weight with larger battery capacity and higher efficiency when applied to products. But one downside...

4. I personally believe that although there are already lithium electric cars on sale, their sales are not very ideal and are not recognized by the public. From an environmental perspective, lithium-ion batteries are more environmentally friendly than lead-acid batteries. 5....

There are three types of batteries commonly used for electric bicycles: batteries, nickel hydrogen batteries, and lithium-ion batteries. Lithium ion battery electric bicycles are lightweight and have a long battery life. What are the advantages and disadvantages compared to batteries?...

6. Calculate the rated capacity based on the required working current and working time; Rated capacity=working current× working hours 7. Determine the design capacity; Design capacity=rated capacity * design coefficient...

2. Determine the number of audio cells in the combination battery, as well as the working voltage and current density of individual cells; 3. Determine the total working voltage, working current, and other indicators of the battery pack according to user requirements, select...
