Now, how lithium batteries can enter the light electric vehicle market can be considered in the following aspects. First, give full play to the characteristics of lithium batteries and design lighter electric vehicles with higher performance. For example, a battery of the same quality can be installed to increase the capacity of the vehicle (rechargeable mileage, gradeability, and load capacity). Second, we designed light electric vehicles with 1, 2, 3, and 4 people respectively. Third, study to improve the quality of cars and reduce prices. Fourth, strengthen sales measures to make it enter the countryside and go abroad. Fifth, let lithium-ion battery electric vehicles enter the market early and withstand the market's exercise.
From 1998 to 2005, the number of electric bicycles in China was used in the field of batteries, which also supported and promoted the development of electronic devices. Nowadays, light electric vehicles have been widely accepted, and lead-acid batteries play a large role. In the past seven years, the production and sales volume has increased by nearly doubling every year. Lead-acid batteries have occupied the position of light-duty electric vehicles at this stage with their mature technologies and low prices.
During this period, the research work of lithium-ion batteries must be continuously strengthened. In addition to improving the performance of lithium manganate and reducing its price, new battery materials must be studied to find new materials with larger capacity, longer life, and lower cost.
The coprecipitation method is the best preparation method. The catalyst prepared by the combination of sodium hydroxide and urea has high activity and thermal stability. The use of NHO to filter out the copper component of the catalyst has shown that there is an optimum copper content in the catalyst and that Cu plays an important role in forming the active site of the catalyst.
