Battery makers across the world are constantly developing novel material innovations to enhance the performance of cathodes, anodes, electrolytes, etc., and system engineers are developing precise engineering solutions to optimize battery pack solutions to provide high-performance battery solutions for various use cases.

As part of their net-zero strategy, many businesses are developing their electrification strategy. As a result, batteries are being used in very diverse use cases, from EVs to electric boats. The demand for batteries is pushing battery makers to create custom-made battery solutions specific to the use case.

Innovation at Material Level - Cathode and Anode Battery makers are developing materials to increase the energy density and performance of the batteries while addressing the ESG requirements. In NMC (Nickel, Magnesium, Cobalt) chemistry, price fluctuation in Cobalt has a significant effect on the cost of the batteries, so companies like SVOLT are developing a new generation of NMX cathode material. Some battery makers are finding an alternative approach by reducing the percentage of cobalt in cathode material while increasing the Nickel content, which has brought a series of NMC cathodes in the market (i.e., NMC811, NMC 622, etc.). In LFP chemistry, battery scientists are working to increase its specific energy density while increasing its volumetric energy density.

In anodes, battery makers are adopting various approaches like developing morphological changes in the existing anode materials or developing alternative anodes like Silicon. CATL is developing advanced morphological innovations in anodes to improve its efficiency. For example, CATL has announced that they have developed a new-gen porous anode material for their upcoming sodium-ion batteries. Battery makers are partnering with material innovation companies and developing silicon anode materials for their battery solutions. Custom cells from Germany and Inobat from Serbia partnered with Group14 to advance its Silicon anode technology.

Innovation at the Cell Level Battery makers are developing new-generation form factors like 4680, 4660, and 4640 cylindrical cells. Tesla has already announced its plan for the serial production of 4680 cylindrical cells in Nevada, US. BMW has announced that they will develop 46xx series of cells for their EVs. BMW said that this 46xx series has the potential to reduce the manufacturing cost by 50%, based on current market assumptions, compared to the current fifth generation. In China, BYD has already launched its blade form factor cells.
