ProLogium partners with NIO to develop solid state batteries

NIO and ProLogium have signed a strategic cooperation agreement in Taoyuan, Taiwan. Dr. Chen­Dong Huang, Electric Power Engineering VP of NIO and Vincent Yang, CEO of ProLogium were the representatives for the two parties at the signing ceremony.

According to the agreement, both parties will set short-­term goal of creating a prototype using ProLogium solid state battery pack. The companies will have more in ­depth discussions with respect to the cooperation in the production of solid­ state battery pack at a later stage.

Vehicle makers have introduced plans related to the adoption of solid state battery for enhancing safety and extending the range of EVs. NIO chose to cooperate with ProLogium due to its high degree of commercialisation and the innovative battery pack construction technology developed specially to take advantage of solid­ state battery.

If solid state batteries are directly assembled as a conventional battery pack, the full potential of the technology cannot be harnessed. Therefore, ProLogium developed a brand­ new packaging approach with respect to the high security, heat dissipating capability and mechanism characteristics of solid­ state battery, creating the MAB (Multi­ Axis Bipolar Pack) technology.

Commonly defined battery cells are nowhere to be seen in this battery pack. Instead, electrodes are directly stacked via bipolar battery technology for the serial and parallel connection. It is equipped with the heat dissipating function at the battery cell stage to save a huge amount of wires, packaging and heat dissipating materials which cannot provide any electricity. It can simplify the design and space of battery management system, greatly enhance the efficiency of battery pack, and comprehensively strengthen the advantage of solid ­state battery.

“ProLogium is at the leading position in R&D of solid­ state lithium battery technology. Solid state battery is safer with higher energy density, so it will become the mainstream form of battery product to be used by smart electric vehicles in the future. NIO will embrace the upgrade of battery technology and constantly enhance the experience of smart electric vehicle users,” said Dr. Chen­Dong Huang, Electric Power Engineering VP of NIO.

“ProLogium has always been pursuing the front-­end technology with high efficiency and industrialisation prospect. Currently it will take another 10 years for the state­ of­ the ­art battery cell technology to catch up with the mileage requirement on the market. In order to take care of the stability and cost of both battery cell, we do not blindly adopt the high activity positive and negative electrode materials with immature supply chain, small amount of shipment, and high price to boost the battery cell energy,” pointed out Vincent Yang, CEO of ProLogium.

“Instead, we propose a method for simultaneously enhance “Battery cell energy density” and “Battery pack efficiency” to invent MAB (Multi­Axis Bipolar Pack) technology to meet the market expectation right now. By combining NIO's deep development capability of “Battery­ Motor­ Controller” system and ProLogium's accumulated technologies in the field of solid state battery, we can create a brand new, or even optimised MAB Multi­Axis Bipolar Pack to bring the truly safe and highly efficient new energy vehicle to the market,” added Yang.
