L'azienda taiwanese specializzata nella produzione di batterie allo stato solido ProLogium Technology ha annunciato di aver stretto una collaborazione con la Nio, Casa automobilistica cinese che ha fatto parlar di sé, in passato, per la supercar EP9. L'auto strappò infatti il record di categoria al Nurburgring.
A proposito di batterie
La partnership tra le due aziende orientali mira a testare e mettere a punto un tipo di batterie allo stato solido di nuova concezione. Si tratta di batterie dotate di pacchi "MAB" (MultiAssiali e Bipolari) che garantiscono buone doti in termini di densità (250 Wh/kg) sicurezza e grande capacità nella gestione delle temperature e nella dissipazione del calore. Ma c'è già chi promette prestazioni migliori.
La nuova tecnologia si basa su un approccio nuovo alla costruzione delle batterie allo stato solido. Dalla ProLogium arriva infatti la dichiarazione secondo cui "se le batterie allo stato solido fossero assemblate come si fa con quelle tradizionali, si otterrebbe lo stesso risultato che si ottiene mettendo un aquila dentro una gabbietta per uccellini". Per questo nella sede di Taipei si è lavorato su un packaging completamente diverso, più adatto alle batterie allo stato solido, ma altrettanto efficace in termini di affidabilità e sicurezza.
Più efficienza e più sicurezza
Nello specifico, gli elettrodi sono impilati direttamente attraverso una batteria bipolare con una connessione parallela e in serie. Inoltre, i pacchi batteria sono dotati di impianto di raffreddamento a livello delle singole celle in modo da risparmiare spazio e componenti, migliorando l'efficienza.
Questo il commento dell'ingegner ChenDong Huang, vicepresidente di NIO: "ProLogium è all'avanguardia nella ricerca e sviluppo di batterie allo stato solido. Queste batterie sono più sicure di quelle agli ioni di litio e hanno anche maggiore densità. Diventeranno presto uno standard diffuso e noi di NIO vogliamo farci trovare pronti di fronte alle sfide del futuro. Con questa partnership ci poniamo l'obbiettivo di introdurre nel breve periodo batterie allo stato solido sulle nostre auto.

Release date:2019/08/22
After the threeminute battery exchange and the fastest pure electric supercar, NIO is now going to revolutionize the power battery technology.
On August 22, NIO and ProLogium organized a strategic cooperation agreement signing ceremony in Taoyuan, Taiwan. Electric Power Engineering VP of NIO, Dr. ChenDong Huang, and CEO of ProLogium, Vincent Yang were the representatives of the two parties for signing this agreement. Both parties reached a series of consensus for setting the shortterm goal as creating a prototype using ProLogium solid state battery pack. They would have more indepth discussions with respect to the cooperation in the production of solidstate battery pack.
Domestic and foreign vehicle makers have introduced plans related to the adoption of solidstate battery for the purpose of enhancing safety and recharge mileage. NIO chose to cooperate with ProLogium due to its high degree of commercialization and the innovative battery pack construction technology developed with respect to the advantage of solidstate battery.
If solid state batteries are directly assembled as a conventional battery pack, it is just like keeping a soaring eagle in a bird case; it cannot fully exploit the advantages of solidstate battery. Therefore, ProLogium developed a brandnew packaging approach with respect to the high security, heat dissipating capability, and mechanism characteristics of solidstate battery, and created the MAB (MultiAxis 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 solidstate battery.
“ProLogium is at the leading position in R&D of solidstate lithium battery technology. Solidstate 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 by Electric Power Engineering VP of NIO, Dr. ChenDong Huang.
“ ProLogium has always been pursuing the frontend technology with high efficiency and industrialization prospect. Currently it will take another 10 years for the stateoftheart 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. 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. ProLogium team is very excited about being recognized by a partner filled with innovation energy like NIO, and the expectation is that both parties can achieve good technology exchange during the coming battery verification and R&D cooperation. By combining NIO’s deep development capability of “BatteryMotorController” system and ProLogium’s accumulated technologies in the field of solidstate battery, we can create a brand new, or even optimized MAB MultiAxis Bipolar Pack to bring the truly safe and highly efficient new energy vehicle to the market,” pointed out by CEO of ProLogium, Vincent Yang.
