The 11th International Conference on Electric Vehicle Technology and Exhibition was held in Shenzhen, China on May 15. Organized by the China Electric Power Research Institute, the conference attracted over 3,000 participants and showcased a total area of 280,000 square meters.
Lithium batteries have become a mainstream product in today’s market, with market penetration exceeding 90%. However, the high energy density of these batteries has raised concerns about their safety, particularly in light of recent incidents involving accidents due to battery failures. To address this issue, despite various manufacturers in the country striving to improve battery safety standards, challenges remain in completely resolving safety concerns associated with lithium batteries.
Currently, there are many enterprises focusing on water-based batteries as an alternative solution. However, these batteries face challenges as well. Limitations in the electrochemical properties of water-based batteries are hindering their development. Presently, the energy density of water-based batteries is relatively low, at around 75Wh/kg, while conventional lithium batteries range from 100Wh/kg to 250Wh/kg. This disparity restricts the application of water-based batteries in high-energy-demand sectors, such as electric vehicles.
Shenzhen is home to several advanced battery manufacturers that are exploring high energy density water-based batteries. The conference highlighted the innovative technologies being developed in this sector. These advancements in battery technologies are expected to contribute significantly to the fields of energy storage, electric vehicles, and emergency power supply.
As the industry continues to evolve, it is crucial for manufacturers to adapt to the growing demand for higher energy density and safer battery solutions. The focus on water-based batteries and other technologies will play a vital role in the sustainable development of the electric vehicle market.
