ProLogium presents new lithium ceramic electrolyte generation at CES

The Taiwanese company ProLogium, which specialises in solid-state batteries with ceramic electrolytes, presented its fourth-generation lithium ceramic battery system (LCB) for the first time at CES.

It achieves an energy density of 380 Wh/kg or 860-900 Wh/L (compared to 359 Wh/kg and 811 Wh/L for the third generation) and reduces the charging time to four minutes to 60 per cent SoC or six minutes to 80 per cent (compared to five minutes to 60 per cent or 8.5 minutes to 80 per cent for the third generation).

According to ProLogium, years of research culminated in the fourth-generation LCB battery with fully inorganic electrolyte, eliminating organic content entirely and increasing inorganic content from 90% to 100%. This small advancement greatly enhances energy density, charging speed, low-temperature reliability, and safety, redefining what next-generation batteries can achieve.

Practically, these advancements mean that users can rely on extended range, “refueling-like” fast charging, improved low-temperature performance and better heat dissipation, which results in a higher safety rating. In terms of charging improvement, ProLogium writes that the time was cut to just 4 minutes for a 60 per cent charge or 6 minutes for 80%. The company states that the energy density can even be expected to improve soon: “Building on our success, we’re nearing our 2026 target of surpassing 450Wh/kg and 1000Wh/L with lithium metal anodes,” said ProLogium’s founder and chairman Vincent Yang.

“True innovation begins with the core chemistry of batteries—reducing charging times and enhancing safety to benefit the entire ecosystem. The EV market can only thrive sustainably when consumers trust battery technology and charging stations operate profitably,” explained Yang at the CES, adding: “EVs shouldn’t just be an option—they should represent a better future.”

Towards the end of last year, ProLogium had also presented a new silicon composite anode at the Paris Motor Show and found a supplier to help with the production of solid-state batteries. At the beginning of 2024, the company had also opened a factory for the series production of solid-state batteries in Taiwan.
