V2G goes commercial: the school bus fleets leading the charge. Zum’s 74-bus Oakland fleet returns 2.1 GWh annually to the grid. Xos entered production V2G in April 2026. About 230 electric school buses now supply 8 MWh to strained grids. This analysis breaks down the economics, the utility programs, the key operators, and the path to scale for the unlikely but perfect V2G platform.
Megawatt charging for trucks: Scania’s 750 kW V2G demonstration explained. On May 26, 2026, Scania achieved one of the world’s first vehicle-to-grid implementations for heavy commercial vehicles using the Megawatt Charging System. The system pushed 1,000 amps and 750 kW back into the grid. This analysis breaks down the MCS standard, the 3.75 MW capability, the depot charging use case, the economics of V2G for fleet operators, and the challenges that remain before parked trucks become revenue-generating assets.
The Stellantis-Factorial solid-state road test: what it proves and what it doesn’t. FEST cells are now logging real-world miles in a Dodge Charger Daytona. The integration required a patented mechanical architecture and validated on a production platform. But 600 cycles is still short of automotive qualification, manufacturing scale does not yet exist, and the road test does not change the fundamental timeline. Here is the honest assessment.
ProLogium’s Gen 3.5 solid-state battery: inside the first mass production line. The Taoyuan facility is manufacturing 185.4 Ah all-solid-state cells at 381 Wh/kg, verified by TÜV and classified as all-solid-state by UL Solutions under China’s GB/T 43568-2026 standard. This analysis breaks down the Logithium architecture, the roll-to-roll ceramic coating process, the Dunkirk gigafactory plan, the Mercedes-Benz partnership, and what the first true mass production of solid-state cells actually proves.
Solid-state vs. semi-solid vs. quasi-solid: a clear guide to battery terminology. China’s new national standard GB/T 43568-2026 has finally drawn the line between these confusing labels. This guide explains the three official categories, the quantitative test that defines all-solid-state, the companies using each technology, and why the terminology matters for consumers, investors, and policymakers.
The rise of LFP: why lithium iron phosphate is winning the volume game. LFP now powers more than 55% of global EV battery deployments, costs over 40% less than NMC, and is being scaled by CATL, BYD, Tesla, Volkswagen, and Stellantis. This analysis breaks down the market share data, the cost advantage, the technology breakthroughs that eliminated LFP’s performance penalties, and the global supply chain realignment that has made LFP the default chemistry for mass-market electric vehicles.
EV battery costs fall below $100/kWh: what it means for price parity. Global battery pack prices fell to a record low of $108 per kWh in 2025, with China LFP packs at $84/kWh and Argonne modeling $96/kWh for 2026. But price parity is not a single event. This analysis breaks down the numbers, the four drivers of cost decline, the regional disparities that remain, and what the threshold actually changes for buyers in China, Europe, the US, and emerging markets.
Sodium-ion batteries reach commercial scale: CATL Naxtra and the 60 GWh deal. The Changan Nevo A06 entered the market as the world’s first mass-production sodium-ion passenger vehicle. CATL and HyperStrong signed the largest sodium-ion supply agreement in history covering 60 GWh. This analysis breaks down the Naxtra battery specifications, the cold-weather advantage, the manufacturing ramp, the cost trajectory, and what the dual-chemistry future actually looks like.
CATL’s Super Technology Day: six innovations that redefine battery performance. From the third-generation Shenxing battery charging 10% to 98% in 6 minutes 27 seconds, to the Qilin Condensed Battery delivering 1,500 km range at 350 Wh/kg, to the Naxtra sodium-ion battery entering mass production, CATL unveiled a multi-chemistry strategy that reshapes what electric vehicle batteries can do. This analysis breaks down each innovation, the engineering behind it, and what it means for the EV industry.
Lithium-sulfur batteries: the £3.4 million bet to replace nickel and cobalt. Gelion, Nissan Technical Centre Europe, and the University of Oxford are developing solid-state lithium-sulfur batteries that use abundant, ultra-low-cost sulfur instead of expensive, supply-constrained nickel and cobalt. This analysis breaks down the CoRe-SoLiS project, Gelion’s NES cathode technology, the 402 Wh/kg performance already demonstrated, the Longspur Capital “Cheaper Than China” thesis, the polysulfide challenge that has defeated previous attempts, and the realistic timeline to production vehicles.
