The current iteration of Li-ion batteries are starting to reach their performance limits. As such, a host of next generation technologies are under development to continue the historic improvements to cost and performance. Silicon and lithium-metal anodes, high-voltage cathodes and solid-state electrolytes hold great promise but beyond materials, various cell designs, such as those that incorporate structured electrodes or 3D current collectors, can also play a role in continuing the improvement of battery technology.
Alternative non-lithium battery chemistries are also under development for applications where energy density can be de-prioritised, such as for stationary energy storage systems. These include various flow, Na-ion and Zn-based battery chemistries. Motivations for developing these alternatives can stem from the need for cheaper, more environmentally friendly storage solutions or from a desire to mitigate potential Li-ion supply chain risks. But are these technologies ready for deployment and with announcements of breakthroughs into next generation technologies a regular occurrence, which technologies and companies will succeed?
